Beta 43 Engine Install on Beatrice. Caldon Canal.

Winter work, 2018. Swap out the original 20 year old Perkins for a Beta 43. Beatrice is a popular and much loved trip boat on the Caldon Canal run by a great group of people and out pretty much everyday from April – October.

Old engine out. All the work was done at Park Lane Services on the Caldon. I’m well setup to do this type of work on the towpath with cordless power tools, genset welder, lifting tackle etc..

Tapering engine bearers modified and profile cut steelwork welded in ready for the much smaller Beta.

New engine partially stripped down to fit under the rear hand rail. Light as a feather compared to the Perkins.

Centaflex coupling and new smaller propellor fitted to suit the new setup. Rudder has to be dropped out and old prop/shaft pulled out backwards while a short shaft pushed in from the front. All done on the towpath with no need for a dock.

Heat exchanger fitted before the skin tank. This transfers excess heat from the engine cooling system to the existing cabin central heating system. Works really well and ultra reliable heating ideal for a trip boat. On Beatrice it will replace the ancient Webasto system. Hospital silencer also fitted. Blanking plate & bleed fitted replacing the original unreliable pressure cap on the engine as optional remote header tank fitted. Charity is really happy with all the work.

Webasto Repair, Pillings Lock Marina.

Called out to Pillings lock marina. Webasto playing up – not starting up and for some time has been taking longer to warm up.

Main fault is that water has got inside the power plug and damaged a terminal in the plug and burnt one of the pins. This fault isn’t that uncommon and Webasto dealers would be changing the circuit board and plug (£300+). If the heater timer is left on it’s possible fuel is dumped into the exhaust as heater continually momuntarily switches on and then off as voltage at the pin drops out under glowpin load.

Only proper way to fix is to solder leads directly to the pins – cables properly soldered to the pins, sealed using adhesive lined heat shrink and then silicon which is hard to see in the photo. This is a 100% reliable fix.

The problem with the heater taking longer to warm up than normal is down to fuel supply issue. The original installer had T’d into the engine feed after a pre filter which is most likely partially blocked. This is a really common error and done to save time in the installation.

Best to install the Webasto fuel supply properly with dedicated feed taking diesel from around 6 inches off the bottom of the tank. Heater now runs perfectly.

Solar Installation. Aston Marina.

Customer contacted me after speaking to a boater for whom I fitted a solar power kit previously. They wanted the best quality equipment so I fitted 2* LG335 panels with my mounting bracket kit and Victron 150/45 Smartsolar controller. 6mm cable from panels to controller and 35mm cable to batteries.

A curved Liverpool Boat/Orchard Marine roof which my brackets fit perfectly. Saw 610 Watts and over 40amps at 12V in mid day sun which is very good for April. Also install a Victron BMV700 battery monitor. Customer very pleased with the job.

Webasto Install. T&M, Stone.

An engineer had fitted a Webasto Thermo Top Z as a replacement for an Eberspacher D5W. The photo shows how badly the install was done – notice they’d used the original 24mm Eberspacher exhaust (Webasto 22mm), Eberspacher fuel pump (which has different pulse rate to the Webasto and heater running way too cool never getting up to temp), and connected Eberspacher 4mm fuel line to 5mm Webasto burner. Also see the header tank feeds outlet side of heater (not low pressure side of waterpump) and this always is a bad idea and making bleeding v difficult. The Thermo Top Z’s were fitted to Rover 75’s and Land Rover in early 2000’s. People will tell you settings are different  – running temp is slightly higher and cut off voltage is higher but this has no affect on how it will run if properly installed in a narrowboat. Only problem with the Thermo Top Z is control units can fail and they’re now nearly 20 yo.

I properly install a Webasto Thermo Top E kit. Steel upstand welded to the swim and heater mounted on rubber mounts. New isolation ball valve and Webasto copper fuel line kit. Hard to see in photos. Customer very happy with the work and noise from the heater through the boat kept and minimum.

Canaline Isuzu 42 120amp Alternator Upgrade.

Called out to a 2010 narrowboat in Penkridge with battery problems on an Isuzu 42 engine. For the 12 months of ownership there’s always been a problem with fridge cutting out in morning. New set of batteries recently fitted at boatyard but problems still persist. Poor output from alternator. I fit this 120amp alternator: 20171010_110603

With a 60mm pulley and Gates Quadpower belt.

20171011_191338Also fit a Victron BMV700 battery monitor and rewire/balance the battery bank. The new alternator keeps up with the Zanussi washing machine. At the same time resolved problem with solar install. Customer delighted.

 

 

Barrus Shire 90 Amp Narrowboat Alternator Upgrade replacing the original Barrus 80 Amp unit.

The most popular alternator upgrade job that I do – I’ve fitted this kit to ~ 200 Barrus Shire engines all over the canal network.

barrus80A

It replaces the original factory fitted 80 amp alternator which is expensive, unreliable and has poor performance providing nowhere the rated 80 amps. The kit I fit is far better in every respect. Charging performance is transformed with tickover output significantly improved.

Barrus90

The shims and a high speed pulley have been made for this specific job and this marine alternator fits perfectly. I use a longer Gates Quadpower belt which increases wrap around the pulley and brings the alternator further away from the exhaust manifold.

Cable sizes should suit the 90 amp output. Notice in the photo with the original alternator the cable size is 10mm. I upgraded the charge circuit to 35mm including the battery link leads and earth.

Have to be careful with the fixings for the terminals – with heat the insulating washer on the B+ terminal shrinks and can cause the nuts to loosen off which can destroy the alternator. I fit spring washers and locking nuts to prevent this. Also the insulated return negative terminal is only M5 and with the original nuts sustained high current can be too much for the contact – fitting good quality copper tube terminals and extra nuts helps this.

Charging has been totally transformed and customer very happy with the job.

 

 

 

 

60 ft Aqualine Semi Trad Narrowboat. Webasto Thermo Top C Heater Install.

The boat has an Alde Compact gas boiler fitted from new. My liveaboard customer doesn’t want to be reliant on expensive and inconvenient gas. I installed a Webasto Thermotop C diesel boiler into the Semi Trad engine bay. All my installations are done to the very highest standards. It’s very hard to hear the heater running from inside the boat.

Originally customer was expecting to remove the Alde boiler but we retained it and the 2 systems work perfectly alongside each other with no compromise. Also fitted the latest Webasto Thermocall module and the heater can be remotely controlled using the Webasto smartphone app.

Customer delighted with the work.

It’s very important the fuel supply and central heating circuit inside the boat are installed to Webasto’s specifications to ensure that the heater performs efficiently and is reliable long term. These are points and basic standards which you might assume every Webasto fitter installs to. Many engineers, boatyards and even main dealers don’t install to these fundamental standards. Above the basic requirements my installs are always neat and tidy and well thought out. The standard looms shortened, clipped and supported properly. Exhaust systems are supported and installed neatly and where necessary extra lagging is used – the lagging sock supplied by Webasto are not great. Fuel pipe is properly fixed and supported. I pay great attention to refinement and add extra features so the heater runs quietly. Sometimes the heater can be mounted on a welded steel upstand on the swim. This is a neat way to install, keeps fuel pipe lengths short, and helps maximise refinement inside the cabin.

Trojan T105 6 Volt Narrowboat Battery Bank Fitment.

Trojan T105 batteries have become much more popular in the last 3/4 years. They are high quality, have a capacity closer to what they are advertised at, are good value and have a long life if looked after.

Typically 4* Trojans will replace 3* standard 110AH leisure batteries.

t105.jpg

On this job 3* Crown 155AH batteries were replaced with 4* Trojan T105’s. 50mm link leads. All loads taken across the bank (which is sometimes hard with the standard short studs with less room for the terminals). Crown batteries are excellent quality but have only lasted 3 seasons of light use which is pretty poor. I think this is partly down to the original fitment of a Beta Alternator controller (on Beta 43). I removed this and fitted a standard Iskra regulator which gives higher charging voltage over a longer time.

Smartgauge also installed – simple to fit and use, and relatively accurate battery monitor.

Isuzu Canaline Narrowboat Engine Wiring Loom Fuse Protection.

I had to completely replace the loom after what I assume must have been the ignition feed to optional 110amp alternator shorted out on the engine bearer. Completely destroyed the wiring loom and could have caused a fire.

Most engine mariners fit a fuse at the starter motor to protect the ignition/engine loom but for this engine they didn’t. Well worth checking yours if you have an Isuzu fitted.

Liverpool Boat Isuzu Canaline Charging Upgrade. Narrowboat, Adverc, Trojans, BMV700.

A revisit to a previous job after I was asked to look into fitting a kill switch for peace of mind while disabled wife is maneuvering through locks.

killswitch

I took the opportunity to take some photos of the previous job.

This was a charging upgrade to a standard liverpool boat with Isuzu 42 engine.

Start battery relocated to welded in steel tray. Fit 3* 12V Trojan Batteries. Upgrade to 90amp Alternator, 60mm pulley & Quadpower belt and fit Adverc regulator adjusted to 14.8V for the Trojans. Fit Victron Battery Monitor. Alternator works very hard generating 60+ amps at tickover. Massive improvement on the original setup.

System has worked perfectly for 4-5 months of Summer cruising every year. Trojan batteries still in excellent shape after 3.5 years.

Customer delighted with the system.

Thornycroft T105 Charging System Upgrade. Twin Adverc. T&M at Salt.

On this job I did the bits the customer couldn’t do and combined 2* 90amp Prestolite alternators with an Adverc twin system. 2* 160 amp split charge diodes. 50mm charge leads. 60mm pulley for alternator driven off the small crank pulley and 65mm pulley for alternator driven off large crank pulley and Gates XPA Quadpower Belts. 700AH Rolls AGM Batteries, Victron monitor.

Adverc Voltage adjusted for the batteries.  System works well achieving 180amps just off tickover and customer happy.

Beta Marine Travel Power Idler Pulley Repair at Aston Marina.

Original engineer had told the customer the Travel Power unit needed to be sent away for repair when actually there was no belt fitted! On this version of cocooned Beta 43 there is an idler pulley mounted on a swinging bracket which acts as the adjusting mechanism and it can be a pain. The idler pulleys bearings had worn into the steel causing the pulley to twist and damage the belt. Rather than replace the pulley we made up a different type of adjusting mechanism.

TPadjuster.jpg

Heavy and agricultural Idler pulleys are frequently fitted to engines with Travel Power such as Beta 1903 and most Barrus and Nanni. It’s normally best to remove the pulley and fit a freewheeling pulley to the Travel Power which will increase the grip the belt can generate. If an idler pulley is also used to tension the belt then an adjusting arm like this can sometimes be used instead.

On this engine it wasn’t possible to fit the freewheeling pulley as alternator is mounted backwards and runs CCW.

Dometic / Electrolux 3.5 Travel Power Generator Rebuild. Narrowboat.

This is part of the process in a typical rebuild on the Bosch Travel Power alternator. A new slipring is epoxied and then soldered on. An engineering firm turns the slipring down so it’s perfectly straight. New bearings are fitted and the rotor is re-magnetised. I have rotors rebuilt to this stage so a generator can be turned around more quickly. It’s not always necessary to replace a slipring – some tend to wear more than others. Only high quality parts are used.

IMG_0933.JPG

It’s important a travel power alternator is serviced from time to time as it’s possible bearing failure can destroy an alternator. The rear bearings tend to fail more frequently than the front. If there’s any play or roughness bearings should be changed.

The earlier Bosch alternator is a re worked low voltage unit popular in the 70’s and 80’s and was never designed to run a poly-V belt system. It’s very easy for owners and engineers to over tension the belt which can lead to premature failure.

Beta Marine often fitted soft aluminum alternator pulleys and often these wear and loose their poly v profile leading to belt slip and over tensioning. I have smaller 50mm freewheeling pulleys which run dramatically smoother than a fixed pulley and increase belt grip and lower belt tension required.

Lister ST Alternator Upgrade. Small XPA Pulley.

Called out to battery problems in Stone on a recently purchased narrowboat. Lucas A127 55amp alternator output poor and doing very little at tickover. Adverc ok. Tidy but badly installed system by well known and reputable boatyard (not in Stone) : cable sizes poor and Adverc battery sense fitted to common post of 1-2-both switch however long cable run  (6mm cable/yellow crimps to domestic batteries) after the switch. Alternator pulley large. Fit a 90 amp marine alternator modified for Adverc. New long span laser cut curved adjusting arm, longer bolts, shims and 60mm custom XPA pulley. Gates Quadpower belt. All cable sizes including earth increased to 35mm and re-routed to shorter runs. Transformed alternator performance quickly jumping to 14.4V at low engine speeds.

stalternator

The ST drives alternator at 1/2 speed off cam shaft alternator output is often poor at lower engine speeds. ST’s can often be improved relatively easily as the cam pulley is normally a reasonable size. I’ve fitted this alternator to 5 ST’s now with great results.

Alternator problems on Narrowboat with Lister Alpha LPWS.

Call-out to Bollington to look at problems with a 4 cylinder Lister Alpha. Newly purchased narrowboat where the previous owner fitted the best equipment which looks good on paper. Smartgauge, Victron BMV, 2 large Victron AGM batteries, 24V 150A Mastervolt Alternator, Victron Multiplus etc.. Problem was with the ridiculously over spec’d Mastervolt alternator (like using a power station to supply a house). Mounting system was complicated and engine vibrations causing all the engine mounts and engine brackets to continuously work loose. This had been an ongoing problem. My solution was to fit a standard 60 amp 24V alternator with a smaller custom 65mm XPA pulley and single Gates Quadpower belt; Remove the 16mm charge leads (150A alternator!) and increase to 35mm due to lack of intelligent charging. Charging system is great and a match for the 220AH 24V battery bank. Engine runs smoothly and transforms the boat. Customers delighted.listeralpha

Vetus M4.14 Alternator and Charging Upgrade on the South Coast.

Travelled to Chichester Marina to work on a beautiful and superbly restored classic 1960’s wooden racing yacht Blue Saluki. Re-engined with a Vetus M4.14 6/7 years ago and the charging system has never been good. Customer couldn’t find a local engineer who was used to working with Adverc systems.

IMG_0902

IMG_0900

The charging setup on this generation of Vetus engine has been badly thought out: The original factory fitted alternators have low output right across the engine rpm range. Alternator spec according to Vetus ranges from 40-60 amp (optimistic figures), alternator pulley size is large, crank pulley small and output at tickover pathetic. The replacement cost of this poor performing alternator from Vetus is extortionate.

My brief was to sort out the charging system. An Adverc system was already fitted with 1-2-Both switch. I fit a 160amp split charge diode; 90 amp Marine Alternator with custom smaller high speed pulley and Gates Automaster belt. Domestic charging cables increased to 35mm (some of original circuit was as small as 6mm). Rewire all batteries (3 domestic, 1 start) with new HD post terminals and marine spec 35mm cable. New Blue Sea isolator switches.

IMG_0899

With jobs like this I tend to load my van with a range of different alternators/pulleys/belts etc… There seem to be some differences in the front timing cover & raw water pump of these Mitsubishi engines and it isn’t always possible to fit the one I intended. Have to play around with pulley sizes as Gates Automaster sizes are limited. Clearance between wet manifold and alternator stud terminals was incredibly tight. I had to grind terminals down slightly and fit all cables before I fitted the alternator. Access particularly poor – pretty sure some fitters would insist the engine lifted out to do a job like this.

Charging performance has been transformed and customer is delighted.
