I can't even find the dipstick, I had a quick look around the engine/gearbox department yesterday but couldn't see one, but to be fair i was really concentrating on the inching system as the pedal doesnt seem to be working (if i press it there's no effect until i get to the point where the brakes operate, when i say no effect, what i mean is the machine drives just the same).

I read elsewhere that the dipstick can be on the left hand side near the upright, i'll have a real close look this morning.

Thanks for the input.

Doesn't it saw what oil goes in the gearbox on the dipstick. Its engine oil I think 10w or 30w cant remember.

Thank you for the reply Triggs.

I only took delivery late last night, i'll check the colour today, but from what the previous owner told me, it looks like it will be hydraulic fluid.

I **think** i read somewhere that some models of forklift use hydraulic oil to power their drivetrains, I always assumed it was "auto transmission fluid", do you know if thats a possibility ?

Thanks for the confirmation that it shouldnt slip that much when cold, my train of thought was that it could either be short of fluid or have a badly adjusted inching brake or maybe a faulty valve in the inching system, please let me know if you think that's not likely.

Thanks again.

"I don't have much experience with that exact model, maybe a caterpillar tech might chime in with specific engine info. As far as trans dipstick/fill port, check under the floorboard. I would check color and odor of the oil leaking to identify which system its leaking from. Its possible the wrong ATF was used because it shouldn't slip that much even when cold."

Thank you for the reply Andrew, it's LPG powered so I assume petrol, either way that's very helpful thank you.

I'll check to see if ther's a propshaft system as you descirbe, thanks.

I only got it last night so will check things out further today.

Do you have any idea how the inching pedal system works ? will there be a hyraulic valve or will it be electrically controlled ?

Is it gas or diesel, if its gas its a Peugeot engine from a 504 car. Sorry don't know the engine model. If its a diesel its also a Peugeot 2.1liter as fitted to 505 pick up and ford sierra/Granada. Its a long time since I worked on one of these, the transmission is in 2 halves I think, there's a part bolted to the engine and a part bolted to the front axle and a propshaft in between They weren't very good from what I can remember.

Thank you for the reply.

The engine that is fitted to them would be helpful, as would anything to do with the transmission.

I purchased it knowing that when cold it required a lot of revving to move it until it warmed up, then it drives much better.

There's a dipstick/cap for the hydraulic oil on the left hand side under the engine cover (right on the mark), i've no idea if this is also the level for the transmission.

When cold it moves like you would expect a manual car to move with a very worn, slipping clutch.

I'm hoping it's something as simple as low transmission fluid, blocked filter or maybe badly adjusted inching pedal, so any information / diagrams on the transmission would be of great help.

Not sure if it's relevant, but the previous owner also told me that when it's been parked up overnught, it drops a small puddle of oil, he told me it's been like this for the whole of the 15 years he owned it, it was just used to lift engines in and out of vans, so he never bothered to do anything with it.

There should be a plate or label somewhere on the top of the engine with specs. What info are you exactly looking for?
