Creeper Gear Box Oil

[Jinma284]

I had to remove the creeper gear box cover on my Jinma 254 today. I was surprised that the oil level is so low. I checked the level on the dipstick and it is fine. Anyone else had it off and thought it might be low? Pat

Pat,
The creeper gear box is filled through the small shaft holes from the transmission gear box. If the transmission level is correct, the creeper level will be correct.
But this also means that when you drain the transmission fluid and creeper fluid you need to allow adequate time for the creeper to fill and then recheck the transmission level. I usually try to let mine set overnight after refilling.
Some people have put an access hole in the top of the Creeper lid just to double check that the level is the same as the transmission level.

If you pull the next cover to the rear off(main gearbox), and measure down from the top lip, I think you will find they are both the same height. The gear boxes don't have to be full. the spinning gears swinging down thru the oil sling/transfer the oil throughout the gearboxes..

I checked the level on the dipstick and it is fine.

Just so we're clear, threaded dipsticks on Asian products do not get screwed back in for the level check. Unscrew it, wipe, set in the hole, remove, check level. And remember; when you put gear oil in through the dipstick hole, it takes a long time to flow forward into the creeper box. Depending upon the temperature, an hour is not unreasonable.

To make sure that you have adequate flow from the transmission housing into the creeper housing, park the tractor on a level surface. Remove the creeper housing top plate. Then remove the dipstick again and use a small diameter dowel or equivalent for a level check. Just insert the dowel so that the tip only skins the surface of the gear oil. Put a mark on the dowel that approximates the bottom of the threaded dipstick hole. Move the dowel to the creeper box. Put the mark level with the side of the housing. Ideally it will demonstrate that the level is equal in both boxes. If the tip of the dowel doesn't touch the surface of the gear oil, it indicates a flow problem.

I measured with the cover off and the level is correct. I guess I was expecting more because so much transmission oil is used. Almost all must be in the rear end. Pat

I had the same concern so what I did was make some careful measurements then drill and tap a hole in the cover to accept a 1/2" pipe plug. I then welded on a piece of 1/8" rod and put a grind mark in it at the proper level. I now have a way to fill it quicker then letting the fluid trickle through the little ports and check it via the dipstick I made.

Good idea Chris. I may try that someday. Got a few other things to work on first. Pat
