Another Lubricant Question

IBPALLETS · Mar 18, 2005

I just got my Emerybuilt [Jinma284 w/FEL] and manual says engine 15/40 deisel oil and all other [diffs and trans] Hydraulic fluid. Called dealer and stated Multitrac fluid [coastal] is great . I was currently using that in my old Kubota so I will continue.

( l and all other [diffs and trans] Hydraulic fluid. Called dealer and stated Multitrac fluid [coastal] is great )

Strongly disagree. And I'd be real interested in seeing that manual myself. I won't pretend to speak for a Kubota, but in a JM284 - EmeryBilt or whatever - hydraulic fluid for the hydraulics and steering, GEAR OIL for the transmission and differentials.

I found the lubricant spec, (such as they are) in the Jepe (Futian Euro Leopard) book. I would guess my dealer told me correct. Here is a picture of the scanned page in the book.

Yup. What Futian is calling "dual purpose" corresponds with the UTF we're talking about, a hydraulic fluid/gear oil hybrid product. The N100D corresponds to it's containing AW100 hydraulic oil, the N68 to AW68. Look for those numbers on the container label before buying.

Jinmas however, aren't engineered for UTF. As I said - for the benefit of IBPALLETS - it's hydraulic fluid for the hydraulics/steering and gear oil for the transmissions/differentials.

I've got a question. If (since) UTF is designed as a gear lubricant ( final drives.. etc... ) why won't it work in the rear end of a jinma? Same question for the tranny.. especially since I see some many questions about the issue of the creeper gear not getting lube with thick gear oil..e tc.

Same for the power steering? just about every other 'modern' tractor I've seen with power steering either recomend their labeld brand of utf for the PS.. or it shares a commpn sump with some other item, again.. using utf.. etc.

Chinese pumps not up to pumping anything thicker than water? Or is there other restrictions that the oil weght is super critical about?

Jinma354 · Mar 20, 2005

I run 303 in the transmission and rear end in my 354. I've had it in there for a couple of years and going on 300 hours. Hope its not doing damage I can't see? /forums/images/graemlins/confused.gif I shorted the 303 a couple of quarts and added two Lucas. Lots of the old timers that have been around Chinese tractors for years say 303 is what to use. I've wondered a few times if I should drain the 303 and run 80w 90 GL-4 but never have. It shifts too smooth with the 303 in extreme cold. I do run gear oil in the front end.

( I've got a question.)
several, as it turns out.

IMPORTANT: BIGBEAR's question that started this thread concerned his 354 JEPE. You've managed to turn it into a Jinma thing, and not all Chinese tractors are Jinma clones. So it's important to note that my responses to you are Jinma-specific and are unrelated to BigBear's original 354 JEPE question, or to Chinese tractors in general.

( If (since) UTF is designed as a gear lubricant ( final drives.. etc... ) why won't it work in the rear end of a jinma? )
I don't recall anybody saying it wouldn't. What HAS been said repeatedly is that "gear oil is for gears", and that "UTF has a gear oil component". But I still recommend non-foaming 80W90 for Jinma transmissions and differentials.

( Same question for the tranny.. especially since I see some many questions about the issue of the creeper gear not getting lube with thick gear oil..e tc.)
The dry creeper issue is one of contamination, not of lubricant choice. It's relative to the dirty 30W that's apparently put in by Jinma for storage and transit before sale, and is one of the prime reasons the kerosene flush is recommended before putting these small Jinmas to work.

( Same for the power steering? just about every other 'modern' tractor I've seen with power steering either recomend their labeld brand of utf for the PS.. or it shares a commpn sump with some other item, again.. using utf.. etc.)
See, there you go again Chris. If you actually owned one of these things, you wouldn't come up with all this second guessing. The smaller Jinmas employ only one pump - in a closed loop configuration. Whatever fluid you pour into the hydraulic reservior is used for everything hydraulic on these units.

( Chinese pumps not up to pumping anything thicker than water? Or is there other restrictions that the oil weght is super critical about?)
Again, it's not the pump - it's the cheap hydraulic suction filter - something you'd already have learned, if you owned one in cold country.

( I shorted the 303 a couple of quarts and added two Lucas. )
If the Lucas has been in there the whole 300 hours, you've probably been running close to a 80W90 equivalent anyway.

( Lots of the old timers that have been around Chinese tractors for years say 303 is what to use. )
I wonder if those old-timers weren't thinking JAPANESE, rather than Chinese? Because UTF is very commonly specified for tractors of Japanese origin.

( I've wondered a few times if I should drain the 303 and run 80w 90 GL-4 but never have. It shifts too smooth with the 303 in extreme cold. I do run gear oil in the front end. )
Assuming you're using 80W90 up front, I recommend a field viscosity test. On a COLD day, loosen both fill plugs and compare the dipsticks side by side. If the Lucas has stabilized the 303 so it doesn't drip any faster than the gear oil, leave it as is - Lucas is too expensive to throw away without justification. But if the Lucas-stabilized oil still drips faster than that from the front diff - change the 303 oil out for a non-foaming 80W90.
