I bought an old 's Lancer boss forklift very cheap,reason it was so cheap was theres no brakes and also an oil leak. The oil is leaking out the bottom of a bell housing between the engine and the transmission.
Theres a hole at the top of this housing and i can see the ring gear,and ive been told that there is a torque converter in here as well. Oil splashes out of this hole when its running. This forklift would have spent a lot of time out in the open,so i think water may have gotten in through the hole at the top,because the oil coming from both areas is white.
I've checked the engine oil and its not discoloured so that rules out any major engine issue. It leaks an awful lot more when its running,i presume this is down to viscosity and not pressure,because it doesnt spray out just drips a lot. I've been told its most likely the transmission seal. It moves fairly slow up a hill and needs plenty of revs,but apparently they were like this from new,but on the flat it moves itself well,so i hope that means the torque converter is ok and not the source of the oil leak.
I checked the trans dipstick and the level is good but the last owner may have been topping the trans or engine up. The oil is red so im presuming this trans takes Automatic transmission oil.
So i have a few questions, Does the trans share oil with the torque converter? Could there be another source of this oil leak besides the trans seal,ie a pump?
Is it a feasible job to clean up a rusty brake master cylinder? Is there a tool or chemicals suitable for this? I think i will need to lift the engine out to sort this leak out. Will the weight have to come off to get the engine out? I've never worked on a forklift before so any advice on how to go about doing this job is much appreciated. I'll get pics up later to help in identifying the model. I can only offer a small amount of advice here; regarding the master cylinder if its pitted inside then its scrap because fluid will simply pass any new seals you fit via the rust pits, secondly I would also look at the brake slave cylinders too as the seals in those may very well of perished on an old truck like that.
Regarding the oil leak I am pretty sure that the torque converter has its own oil supply, is all of the leaking oil milky white or is any of it red in colour? If the leaking oil is red then its certainly ATF automatic transmission fluid which could of leaked from either the torque converter or the gearbox, either way it would really require the engine out to sort it. I am no FLT expert but its a fair bet you would need to lift off the counter weight to remove the engine and transmission. Hope this helps and good luck.
Re: Lancer boss Forklift Post by BulldozerD11 » Thu Jan 27, am There is a firm that refurbs brake master and slave cylinders think they sleeve them that advertises in some of the old tractor mags.
A number of early ones were based on tractor skd units reversed. Re: Lancer boss Forklift Post by Green Dragon » Thu Jan 27, pm Ned, you don't say what model you truck is, but if the oil is leaking from the flywheel housing it could be the seal between the tansmission and the torque convertor that has failed.
Usually ATF is use in these transmissions. On forklifts this usually means an engine out job. Whether the counterweight has to come off depends on the model.
