I'm looking for a repair manual for my Yale G52 forklift

Awesome thx for that

I found that I have a manual for the 1967 G82. 90-140 wt gear oil in the differential, type A ATF fluid in transmission, and 42-46 hydraulic oil. There is a seal between the differential and trans.

I'll check where that tube goes and if the oil type is on the stick. Cant thank you enough for your help on this! I did find a manual on Ebay last night I ordered. Cheers!

the dipstick in the front, does it come out of the differential tube? or does it go back into the transmission case?
If it comes out of the differential tube then it is the fluid level for the differential fluid and you would use 90wt oil in the differential.

If the dipstick is coming from the transmission case then it is separate from the hydraulic oil and does not share the hydraulic system.
Now as far as which fluid to use?
The hydraulic system uses 10wt oil (todays equivilant is aw32).
The transmission would most likely be atf, check the dipstick, it should tell you which type fluid to use providing the stick is not corroded up and unreadable.
To be completly sure on the fluid types and weights i would refer to the specifications in the manual.

I'm going on memory on this and it's been decades since i worked on one so if you could find a manual i would do that to be honest just to make sure.

Hey Swoop223 my bad that's a G82. Small machine 2500bls I believe. It has the IH 135 in it on gas. It does have the dip stick on the front. So does that mean the Hydraulic oil circulates through the trans and Diff? I've drained the hydrc oil tank and the diff. I've put an ios46aw hydraulic oil in the tank, but haven't put anything in the diff fearing there may be a wet clutch. Should it just be an ATF? Or will the 46aw work? Or something else?

scotty,
both pedals may move when the clutch is pressed but it is the linkage between the two that makes it appear that way. I believe the design is made so when the brake pedal is pressed it disengages the clutch at the same time, so naturally when the clutch pedal is pressed the brake pedal may move down a little.
As for the oil used, it sounds like it has an oil clutch so yes the transmission fluid would be the same as the clutch housing fluid.
Some units did circulate the hydraulic fluid into the differential but i would check the differential tubes for a dipstick or a dipstick pointing out from the front just under the right side of the firewall/kickpanel between the mast and firewall panel. If you do not find one there check for a level plug in the differential housing bell in the front.
As for the engine, i never saw an IH engine in one of those but i know they did use a chrysler slant 6 in some of their units, probably the G51 series. I didnt run across too many L82's in my area.

I believe I have a l82c as well. Mid 1960's vintage best I can tell. What I need to know is, what oil to use in the diff? It has a clutch, and when it is pushed down to engage it, the brake pedal goes down at the same time. It looks like the trans and diff use and share the same oil?? Thx in advance for any help on this.

It's been quite a while since I've seen one of these. I get my tune up parts at NAPA. If a picture is sent to my e-mail of the distributor, I may be able to help. I have old buyers guides from NAPA which have the pictures in them. Their newer books don't have nearly as many pictures, but if you know the part #'s, the parts are ususally available.

I have the NAPA part #'s for a L82C with the IH engine, they may be the same- don't know for sure- they are as follows:
Distributor cap: IH350
Rotor :IH300
Condenser :AL869
Points :CS1600

As far as the ig. wires- I use the metal core-cut to length NAPA # 700172.
Hope this helps.

You'll have real fun when the brakes need service- it's got the weirdest self adjusters you'll ever see.

BTW- Duo- you're correct- the ones I serviced had the continental flathead engine installed

Yes it does have the IH engine. Engine model is a U-123, at least that is what I am showing.

The # on the engine definitely sound like an IH # but I thought they only used that engine in the G82 series truck. The IH engine is an overhead valve engine.
All of the G52 series trucks that I've seen used a Continental F124 flat head engine.

WOW, your good mrfixit

I think you have a International Harvester C135 engine. They used that in farm tractors also. I don't know about the points but maybe NAPA could look that up. Distributor cap is Yale # 5104828-00. The ring gear is # 0155309-00.
