Ford Lehman Marine Diesel engine stuff

By mark on Feb 21, 2009 | In News, Fixing stuff | 24 feedbacks »

Had a few emails over the last month or 2 from folks that have googled upon us with a similar Ford lehman engine to ours, ours is the Lehman 2715e.

so thought it it might be useful to stick on or 2 bits on here and let google do its stuff for anyone else in the same boat (ho ho!) as us

had a couple of enquiries about starter motors. First off, avoid anyone company that has the word marine in it! Find an Auto Electrical distributor, and ask for a Lucas starter motor for a ford lehman 2715e. the lucas part number is Lucas 77121A 12V. The mariney type chaps wanted anything up to £500 for one, the auto electrical type chaps charged us £100 or so. Other engine bits, like the oil pressure sender are bog standard units, pretty much any 12v oil pressure sender will work. The temperature sender that screws into the cylinder ehad has the following numbers on it: 23B8, BM1, and 41953 in case anyone eneds to go down that particular avenue, and the alternator that is fitted to ours is another standard Lucas part - A376, which also happens to be the same alternator that was fitted to Ford Fiestas up to the Mk3 version. Hopefully that little lot might help someone somewhere

And finally, if anyone needs a manual for the borg warner velvet drive, or the Ford Lehman 2715e engine, or part numbers for the engine, I've stuck some PDF's I found up on here:

Borg Warner Velvet Drive Gearbox Manual

Ford Lehman 2710 2715 manual & parts lists

Ford Lehman 2710 2715 owners manual

might be worth bookmarking this blog post, I'll probably added a few more bits of useful stuff and as and when I stumble upon it. As much for my addled memory as anything else!

/****

just another wee note, for major engine components check out Ford Cargo 6D engines, and New Holland Combine harvesters

update, October 2009:
just added a marinisation pdf, how to marinise an engine, particularly ford diesel:

Marinising the Ford Lehman 2700 - 2715 series of Diesel engines

and just found the parts list:

Ford Lehman 2700 complete parts list & manual

will be giving her an overhaul and service shortly so will list the part numbers or equivalent part number and supplier for all the necessary bit n pieces, oil filter, fuel filter, injectors, sensors and so

hi greg, there's one on ebay at the moment - item number 120439535694

I believe the block/head is the same as was used in the ford cargo 6D trucks here in the uk and also in New Holland combine harvesters as well

I live on the west coast of Canada and am looking into buying an 36 ft. old Taiwanese trawler with a older Lehman engine (5000+ hours use). I wonder how they mostly fail from use. i.e. what gives out in the engine? Is it the cylinders and bearings or stuff in the head? If it were the latter, one could presumably do a less costly head rebuild and not have to pull the whole engine for machining etc. P.S. Thanks for the manuals - very useful.

Hi, just found this site, very interesting and helpfull. I have a 36ft motorboat with a 6d 120hp/borgwarner fitted. Just been out to her and found I'd left the water intake on and this has filled the engine, god what a bad day I'm having. Hope to be able to empty the sump and be OK??? Very usefull the PDF wokshop manual.

water in the engine?? If its water that has just got in the sump from the breather or dipstick probably be alright, change the oil straight away though

you might find you got water in the gearbox as well if its been that far under water - we're borgwarner boxed and our little flooding incident a few weeks ago filled the gearbox as well

there's a link to a marinisation article up the top for the ford lehman as well:

looking for some kind of an idea of how many hours a lehman 85 hp marine diesel should be expected to run?the boat is 27 years old.I assume that to be the age of the diesel.also assume it has been taken proper care or ..(maintence wise).any realistic coment from expience greatly appreciated

bit of a how long's a piece of string question that one!

I had heard 5000 hours between major rebuilds, suppose it'show the thing has been used and/or abused in its life thats the key.

if its any help, ours is an early 70's motor, no obvious scars to suggest its ever been in bits (all the bolt heads etc are still flat and true), so I reckon ours has had nothing more than the normal servicing when needed. Pansy used to have a Kelvin K3, and whilst it would be lovely to still have it, the fact that ford parts are cheap as chips, and they are pretty reliable workhorses, makes it worthwhile.

Hello, we have a 2715E in our lobster boat and last day during haulout the "cold start" button on the side of the fuel lever did not click into it's usual spot. Is this a linkage issue or is there something internal that needs to be looked at. If it is in fact a cold start button it doesn't work like it has in the past. Any info would be greatly appreciated.

hi ray,
for what its worth I'm sure the cold start button has ever done much on ours either. Its not really a cold start do much as an excess fuel device that sticks extra fuel in to up the compression and help it start. on ours it moves but has little effect on cold starting. Have just discovered there's a heater system that can be fitted to the inlet manifold which makes life much easier. Will dig out the details, its just a few quids worth/bucks worth of bits

what ratio is you borgy box? I've got a spare one.. the one that's in is 1.5:1 and only has about 450hrs on it. I've got a 2.1:1 I'm replacing it with because we need a bigger ratio to get the prop gearing right

hello All nutters, am just rebuilding the ford 380 in my working boat conversion, and found enginefixuk (ebay seller) a good source for parts, i've had my crank reground and am replacing main and big end shells,rings and obviously all gaskets, found i got the parts required for upto half the cost of my early quotes using good old ebay (tigger1590 for gaskets) though as yet i'm struggling to find decent price for a damper plate (i have a 2:1 velvet drive box) if anyone has any suggestions? would be appreciated, cheers,
