Jinma 204 tranny fluid and clutch question

RandyS · Apr 21, 2007

Drained tranny fluid out, lots of water came out first. Should I "rinse" it out with something before refilling it? Also, what do I put back in, standard tranny and I live up north.
Secondly, my nephew said the clutch slips. What to do about that? We have adjusted it a couple times before.
Thank you.

Flush with kerosese, twice if what comes out the first time suggests more is better. But please explain what you think constitutes clutch slip. And specifically what did you do the first two time to think you might be correcting it?

Greg,
I'm not sure about the clutch slip thing. My nephew usually uses the tractor and not me. I'll see him tomorrow and ask him. Think his father had to take a plate off the side of the engine area to adjust something.

Your choice what you put back in,,,,I have had 40 weight nondetergent in my 254 for about 570 hours with the addition of lucas,,,,don't know,,,many use regular gear lub/oil,,some use 30 weight,,some I have heard even use a auto type oil univeral oil,[very thin],,,who knows,,what does your owners manual say,,,whats that,,you ain't got one??,,,I'd go with a thicker rather than a thinner what ever,,but it seems it really don't matter,,I wouldn't flush with kerosine either,,these things have voids and holes that I'm not sure you can drain dry,,I would just drain and fill back up,,if its got more water,,you'll be able to tell it,,,than do it again,,make sure you look for drain plugs,,there are several,,not just the ones in back,,would feel better with a little bad oil mixed up than oil with kerosine,,thingy

Ditto what greg says.

For oil.. I'd use an 90w, 80w90 or 75w90 in cold weather.. unless it specifically called for 85/140.

For clarification, I don't recommend a full synthetic (75W90) on a Chinese tractor, until it has logged at least 300 hours of break-in time. And summer's are hot enough in this part of Kentucky, where I've begun to switch over to 85W140 on my own tractors (and straight 140 in my mowers). I've not fully committed yet - but am giving serious consideration to eventually moving 75W140 full synthetic for gears, 5W40 full synthetic for engines. Haven't thought far enough ahead to the hydraulic fluid yet.

But synthetics are so danged expensive, that a very thorough flushing is only sensible. You don't want putting nice clean synthetic into a dirty sump. If you're tempted to use diesel fuel instead of kerosene for your tranny/differential/hydraulic flush, kero has a more advantageous specific gravity. It settles out (separates) better from the lubricants to alleviate worries about residuals. Short version; it drains better.

But I'm a long way away from where you're at right now Randy. The reason for flushing new Chinese tractors is to purge the sumps of the metal by-products of manufacturing and break-in (not to mention the substandard fluids that they're shipped with).

I sold lubricants for a number of years. Oil cools, cleans and lubricates. Synthetics do not extend drain intervals as many advertise. Consequently, I'd stay with standard oil, such as RotellaT15w/40 in the engine, Shell Spirax 80w/90 in the differentials, and in my tranny. I run ATF in my hydraulics. I have a KAMA TS254C, and that's what I am using year-round. North Idaho gets real cold in winter and plenty hot in the summer. Oil's pretty cheap compared to a failure. I drained it the day I got it off the delivery truck. Ran 25 hours and drained everything again and refilled, changed filters, etc. Now I change engine oil every 50 hours... I've had my tractor less than a year and have 305 VERY HARD hours on it. No problems other than the clutch that I fried cause I was riding it (duh).
