  1. As above. It looks like the vetus unit on mine. the two stainless cap screws go through the motor stool, the wall of the tube and into the bronze hub carrying the impeller inside the tube. Don't undo them unless your in dock and have access to the tube to 're- make the joint once you disturbed it. It's not the most robust mounting arrangement but seems to work ok. If it's not leaking leave well alone. Again, A coffer dam or a full height bulkhead is a good idea should the worst happen.

    4lk fuel consumption

    This was an attempt at actually measuring fuel consumed whilst moving, against a stopwatch. Once you add in other variables, like river currents, waiting at lock landings, battery charging etc, the results would be different again, more in line with your results. Remember I'm only measuring over one hour under optimum conditions, I.e engine fully warmed up, very little parasitic loads etc.

    4lk fuel consumption

    Have been playing about with a calibrated fuel measuring flask for a while now, it's really just a little two pint tank with a glass tube on one side marked in 1/16 pint divisions. Results so far are between 1 9/16 to 1 5/8 pints per hour, over timed 1 hour runs, with fully charged batteries, at normal cruising speeds. This bears out the average of a litre an hour, for most narrowboats, this being a little less, at around 0.9 litres per hour. This is for a 65 foot trad, driving 24x19 prop through 2:1 reduction. Draft 30" alternator load minimal, 5-6 amps, lighting load. Probably not far short of what a modern engine can achieve. The above figures were measured over time, not distance travelled, at a sensible cruising speed.

  5. So the plan is to make a hydraulic coupling between your engine, and the input shaft of the enfield drive? So the reduction and clutch function is being retained? I can't remember, does the enfield have an integral clutch for fwd/astern? So your going to have to make two adaptor plates, to carry the motors/pumps, two couplings, pipework between the two, a header tank, a relief valve, pressure and return line filters, and possibly a cooler. If you can afford it, it would be best to let a specialist company specify the equipment, and let them take full responsibility for design, installation, flushing and commissioning. Flushing is vital, and cannot repeat cannot, be over stressed. The slightest suspicion of contamination in the system, be it dirt, swarf, water etc, can destroy a pump in seconds. Hydraulics are very reliable, as long as the oil is clean and free of water. It ain't just a matter of coupling a couple of motors together with flexible hoses! Make a start by looking at what torque and speed input the enfield drive requires, and find a motor that fits the bill, from makers catalogues. This will give you the required flow, which will allow you to size the driving pump and pipework. Look at Dennison, Parker, Vickers, Bosch hydraulic catalogues for some ideas. Try and keep the working pressure as low as practical, by using large displacement low pressure pumps rather than high pressure low volume pumps. Best of luck.

    DIY facilities north west

    Portland basin has a good covered drydock not expensive either. For longer dockings try Jalsea marine northwich, plenty of hardstanding and facilities.bit hard to find, you drive through a council estate to get to it, it's . On the weaver.

    BMC 2.2 and 2.5 crankshafts the same?

    My father ran a fleet of fx 4 taxis in the late 60`s through the 70`s with the bmc 2.2 engines, clapped out ex london rejects they were, held together with chewing gum, spit and hope. These all had the 3 main bearing cranks, being 2.2s . in 1977, queens silver jubilee year, he 're named it jubilee taxis, and splashed out on a brand new fx4, mnc 385p. The only new vehicle he ever had. This had the new 2.5 engine, an alternator, not a dynamo, and those funny little heater plugs in parallel, instead of the 2 volt series things that never seemed to work. It was an improved & updated replacement for the 2.2, with 5 main bearings. I'm wondering now if there was an early version of the 2.5 with a 3 bearing crank, later ones having 5? I was talking to mate of mine today who had a taxi repair business around this time, he remembers bmc 2.5`s having a 5 main bearing crank too. I put one in a series 2 landrover once, was a popular conversion at the time.

    BMC 2.2 and 2.5 crankshafts the same?

    No. Bmc 2.2 had 3 main bearings 2.5 has 5 main bearings.

    Reddish aqeduct

    Reddish isn't that bad, compared to errm.. no can't see any tourist potential in it either. Might gentryfy the area a bit though, put nelstrops mill and lanky hill on the map.. if we renamed it New Chelsea or something, it might attract rich foreign investors, bit like when they re named ancoats and beswick New islington. Was just wondering like what the aqueduct looked like, the canal pre dated the railway, so it must have been built around 1860s ?

    Reddish aqeduct

    I used to work down at the bottom of station road in the 1980s, at Rowland grinders, shown as climax works on the map, and remember the hump on station road where the canal bridge was, by adamson containers. Alas reddish electric is no more, a very new housing estate there now. My father remembered it being built early 50`s . Reinstating the aqueduct across a double track railway is going to take some doing, don't think it's going to 're open any time soon.

    Reddish aqeduct

    Was cycling the fallowfield loop the other day, and tracing what is left of the stockport branch canal around debdale park reservoir and north reddish. There was an aqueduct carrying the canal over the railway just before reddish north station. Anyone remember it? Or know what it looked like? Or when it was demolished ?All traces have vanished, no abutments or anything can be seen from the bridge over the railway at reddish electric depot, looking towards reddish north station. Nothing to be seen on Google earth either, it was very close to Beresford crescent apparently.
  13. I'd suggest that unless your interested in the engine per se, get something modern and supportable. After all you are missing out on 60 years of diesel development having an old engine, like a snapshot from the past. Lk spares are out there, but you have to track them down. The last ones were built in 1968 ish. Check If there are any spares with the vessel, and try to obtain them. Get both the engine manual, and the workshop tools book, read and inwardly digest. They are no more difficult to work on than any other engine, though like most Gardner's, you can't withdraw the pistons up the cylinder bore, the cylinder block is lifted from the crankcase instead. The crankshaft runs in thick wall gunmetal bearings, not thin wall shells in the accepted sense. The bearing areas are massive, and wear very slowly. They do have one unusual feature, that the Cambox and timing Chain are lubricated by surplus oil from the pressure relief valve. In a worn engine at idle the pressure can drop enough to starve these of oil. 37 psi is about right. The sump can corrode, I've broken a couple of badly corroded engines for spares, the alloy used is a magnesium alloy with the trade name Elektron. Most Lk`s had cast iron blocks and heads, though there was a special all aluminium version for private cars, but I think these were to special order and dropped during the war.
  14. No more of a liability than any other engine really. I've owned Gardner's for well over 30 years now, and the lk is a wonderful engine. PROVIDED, IT'S in good condition, I.e built to the correct running clearances, and properly set up. They can be a right box of frogs if they have been codged up, don't just look at the shiny bits. If you get a good one, you'll love it, there not too big for a 60 foot plus boat, but need to swing a big 24" prop if driving through a reduction box . They have a smaller bore and stroke than the lw series, and can rev to 2100 rpm against the lw at 1700. Bore glazing won't be a problem if you use the right oil, and it shouldn't smoke if the injectors "sprayers" are right. Spares. You won't need any! If it's been done right. You'll never wear it out. The oil filter is a washable fine gauze, only the fuel filter needs changing and these are readily available. As for rpm , mine drives a heavy, 22 ton 65 foot trad through a 2:1 scg box , 24x19" prop. 400 to 600 rpm on shallow canals, 600 to 900 where you can get a move on. It will go up to 1850 on open water, but becomes uncontrollable. They are definitely an enthusiasts engine, just don't look at a 1935 designed engine with 2017 eyes, things have moved on. It will smoke a bit till it's warmed up a bit, but should be clear after a few minutes. That 2lw crank looks like fatigue failure. Not enough inertia in the revolving mass at idle to iron out the torque reversals. Comes of running too slowly for too long. Shame that, that's one crank ruined, they aren't making any more.
