    Got the trans and diff out. Don't like all the rust.





    Looks like the compartment could use a cleaning.





    Got the diff and trans inside and ready for inspection.





    Couple of pieces of metal loose inside.





    Here is a source of extra metal, no rollers in the pinion support bearing

    OOOPS! This does not look good at all! Lots of nice aluminum shavings on the screen. Also a broken shim on left.





    Here is the source of the shavings. The gear on the right shed some parts and chewed the aluminum ring.





    Here is the gear. All of the bolts were finger tight and the 4 missing bolts were chewed up and lying in the bottom

    Wow more exploded views of Hyster components.

    This is uncanny you found all these issues, you must have a 6th sense!
    It's like you needed to find something wrong....and did!

    Good work so far!

    How about getting the wheels chromed on re-assembly to go with
    the new paint??

    This is impressive! Wish I had the time to do this with my forklifts! They will be good for a long time if you can knock out these issues

    The parts are my main concern. The oil pump seems OK but I'm concerned that some of the garbage found its way into the torque converter.

    As for the wheels, I'm looking for those nice spinner wheels like you see on the pimpmobiles.

    As far as the steering, it's a two piece rim and the tire just flops around with about a 1/4" space between the tire and rim.

    This was at the not pretty stage before but we are now traveling rapidly downhill.

    Here's a closer look at the clutch pack with the chewed aluminum plate.





    Here is the disassembled unit.




    This is one of the better clutch plates. Note the lack of lining on the outer portion.




    This is the front faceplate. That white powdery looking stuff is finely ground aluminum shavings.




    Up till now I was hopeful that I could get this working even if I had to make some parts but this is going to require external sources.

    The guy I got this from says he might have another but doesn't know if the trans is intact. It has no engine.

    Anderson forklift tells me he can get most of the gaskets but has to check his archives for other stuff.

    I didn't really want to 'reply WITH quote' but that seems to be the only option at this point....
    Anyway, which parts are/were actually made custom by/for Hyster, and which were purchased?
    Are those clutch packs something they bought or made inhouse?

    Dunno
    I talked to Chris at Anderson forklift and he's going to get back to me.

    Till then I won't know where I stand.
    My activity calendar suddenly filled up which is slowing me down a bit.
    I'll never understand how I ever found time to work 8 hours a day.

    Any progess ??? There was a YE40 in a forklift scrapyard here in Phoenix, but I believe they scrapped it when the price of steel went up. I'll double check, but it would have been a good source of parts.

    If you pull apart the 90 degree gearbox that drives the cooling fan I would love to see pictures of it.

    I've got a line on another YE 40 in Vegas. I'll have to check it also.
    Haven't gotten to the fan, I do have several people saying they are looking for parts.

    May have a source for clutch plate rebuild.
    Meanwhile I'm looking at the seal (# 1 in first pic of post 46)



    It looks like a fine crystalline structure. Could it be some sort of cast?
    I may have to try to make one if nobody has one.
    I need to find out what material it is.

    I'm currently buried so this goes on the back burner till I find some parts.

    Don't know if I would ever admit this in public, but I bought another YE40. I don't have it in my possession yet. Could be a parts donor or a runner not sure.

    Turns out the other Hyster is a HE 50 with a side shift on the forks.
    It's missing the engine but the trans looks to be the same. Also has the floor plates.

    It's in the back parked on soft dirt and sunk in to the frame so it will be a bit to get out.

    Default Service Manuals...

    I just purchased a pair of manuals for my new to me '64 Hyster S20A from a guy via Craig's List. I paid $25.00 ea for a Customer Edition Parts Manual and a Service Manual. He claimed to have all kinds of Manuals, so you might give him a try. PM me for his contact info.

    Thanks for the interest. Did you get your YE 40?

    I finally got someone to fess up on the parts manual.
    Gary at Bern's in Calif. faxed me a copy of the trans layout and is currently checking on the parts needed.
    Hit a dead end on Keythl's lead, he has nothing for my unit.

    Meanwhile the wife's cancer took a turn for the weird so most of my time is spent going to doctors and her chemo.

    Mr Kimfab,

    Sorry to hear about your wife. I hope it all goes smoothly as possible for you. I recently had a friend go through chemo and he just checked out fine....no more cancer. So good things do happen with chemo.

    I should be getting the second YE40 next week......moral to the story don't buy large heavy objects far away from you. This one is a manual trans.

    Probably the voice of insanity talking here. Got the other YE40 forklift which runs, but needs some love like they all do. It is a two speed manual shift....scoots along pretty quickly in high, but the steering gets ultra sensitive. Both seem to have different "personalities......guess that comes with age....wouldn't know anything about that

    Notice the slots for radiator cooling air flow are different and the hood vents are different. The all yellow one appears to be an older model.

    I didn't want to mess up this outstanding rebuild thread with worthless comments, but I cannot help but admire your work. I recently went through some repair on a Yale fork lift that I had bought, and it was acting up on me. I had to fix it because I needed it. I did not go quite as far as you did, but I almost pulled the engine and the counter weight.

    Anyway, I do have a couple suggestions that may help you. First, if you value your engine, go to Jegs or maybe a local car parts place and get some cam break in lube. That moly grease you found in the oil pan could have very well been from the assembly process. I suggest this, because a new cam will be destroyed very quickly if it is run dry right off the bat. A cam gains some of its strength from work hardening, early in its life. Just smear it on all the lobes, so they have instant lubrication when you fire it up. I would also suggest adding a zinc addative to your oil, and with each oil change. It is a hot rodder trick, and with the EPA forcing the removal of zinc, many new rebuilds were failing. These older engines rely on zinc in the lubrication. This will also help with cam life.

    Other than that, it looks like you have it well in hand! Outstanding work.

    I would also like to add my prayers and thoughts out to your wife's speedy recovery.

    Bill

    Assuming S50 = 5K capacity, it probably weighs more like 7,500 lbs. And even if it was brand new Chinese steel it would still weigh 7,500 lbs, as otherwise it couldn't pick up 5K... pesky geometry and all that.
