Changing lubes

[Degolyerent]

My neighbor has a Jinma JM224 he wants to service it but needs some info. What type of gear lube does the transmission and creeper case use? And I believe from what I can gather it uses 5.55 gal. ?? I see it has a dipstick to check it and I understand that it takes a little time for it to flow into the creeper case. Also what type of Hydraullic oil should he use? I see there is a filler tube behind the seat, and it uses 2.38 gallons but I did not see a place to check the level of fluid.
He also has a problem with the 4wd it seems to go in gear but the front end does not work, is it difficult to check the front shaft? Any info you can give me I will relay it to him.
Thanks
John

Cool to moderate climates use 80W90 gear oil in the creeper/tranny and both differentials. When you include the front, I think the total is over 6 gallons. 8W140 works better in warm to hot climates. AW32/ISO32 hydraulic fluid in cool to moderate, AW46/ISO46 or AW64/ISO64 in warm to hot climates. You found the right location to fill, that's where you check level too. The dipstick should be attached to the vent/fill plug.

Is the 2wd/4wd select lever a direct connection to the housing? or does it pull a cable that connects to a different part of the housing?

I guess you would say it is a direct connection to the housing, he took the cover off and you can see it hooks to a rod that runs toward the rear of the tractor( inside of creeper cover)
Thanks for the info on the lubes that is very helpful, I thank you and I am sure my neighbor does also.

Ok. Two biggest problems with that lever is rust and broken roll pins. If the lever itself is stuck, it can be freed (eventually) with WD40 or PB Blaster. If it moves but doesn't engage/disengage, check for a broken roll pin at the base of the lever. That's how the vertical lever is attached to the horizontal shaft. Less common, but not unusual, would be if the shift lump inside has broken. To check that you must again remove the cover plate. The shift lump is the fingered device at the end of the horizontal rod.

Take the Silver cover with the rubber boot on it loose under the engine, the shaft has 12- ball bearings in couplers that drive the 4 x 4 .Most of the time its a broken circlip that lets the ball bearings fall out. If you need more direction give us a call 979-865-4002 it's pretty simple to repair most of the time

Degolyerent-

Before you pull the rubber covers off the front drive shaft, be sure you're working on a clean floor or a piece of carpet or plywood or something like that - if the balls are, in fact, loose, they'll fall out on the ground and promptly get lost. When you go to put them back in, use some stiff grease to hold them in place while you put things back together. All in all, the job is pretty straightforward, you just don't want to lose the balls.

Hey thanks for the replies y'all,I will get with him and let him know what to look for. I will get back to you when he figures it out.
Thanks

Well he and I fixed it today the circlips were broken on each end of the driveshaft, it was an easy fix. I want to thank all of you for the feedback that you gave. Thank you very much

Thanks for the update - I hate it when I don't know how it turned out! Glad to hear you got it fixed easily.

I agree with Rich. Glad it was an easy fix.
