3 questions

TractorGuy1 · Nov 24, 2005

Both questions are for a Jinma 224

1. What should I set the idle RPM at.

2. To remove the cover plate for the creeper gear do I need to remove the creeper shift lever first or will it come off with the plate. If it needs to be removed first is this done by tapping out the roll pin through the shaft.

3. Should I put a few hours on the tractor before adjusting the clutch plates as the PTO is allways rotating when the clutch is pressed down.

1. Somewhere in the neighborhood of 800 rpm
2. no need to remove the lever, but be VERY careful of the gasket
3. parasitic friction turns the spline, you'll very likely never adjust it out. I can stop mine by simply grabbing it with my hand.

TractorGuy1, If I did it correctly...the link will show you some pic's with the creeper/shifter cover removed.

I would NEVER grab a PTO shaft with my hand, unless you want your arm torn off in the event your wrong and it is engaged,(PTO's love long shirts) Hook up a implement and see what it does, way safer, unless you like the nick name Lefty.
Many lose limbs every year because they get to comfortable and think they know more than that tractor does, the tractor will bite when you least expect it.

I wouldn't either TAT, that's why I said spline.

Now if a PTO shaft itself is turning with the PTO lever disengaged - THAT's a whole different story, one that would in fact suggest a PTO clutch adjustment may be in order.

But you can stop a parasitically turned spline by hand without fear.

To suggest that he test it by grabbing the spline is dangerous, UNLESS the tractor engine is off. Maybe somebody could sit on the tractor and depress the clutch and see if it can be turned.

I know where your coming from, but your going to get a lot of heat on that one Greg! /forums/images/graemlins/blush.gif

Tool Man,

I know where Greg g is coming too, we both have KAMA 454s. The spine will rotate very slowly when not engaged. I mean very slow. There is no doubt when it's turning at 540 or 1000 rpm.

He is just trying to prevent an unrequired adjustment or concern. I supose if in boubt, use a 2x2 apply friction to the spline.

( Maybe somebody could sit on the tractor and depress the clutch and see if it can be turned. )

Maybe somebody could point out where I recommended anybody grab the spline on a running tractor. If you look again, you'll see I simply stated that I can grab and stop MINE without difficulty or fear.

Nevertheless, it doesn't matter if it's a KAMA or a Jinma. And you don't need the second person.
With the tractor RUNNING and no PTO shaft on the spline
1. set brakes
2. place transmission gear select in Neutral
3. depress clutch and engage PTO lever
4. release clutch and STOP ENGINE
5. dismount tractor and try to turn spline by hand

If properly engaged in step 3, spline should not rotate

6. disengage PTO lever
7. try to turn spline by hand

If properly decoupled by step 6, spline should rotate.

If the spline cannot be moved by hand at this point, ONLY THEN should a clutch adjustment be considered.

You can STOP yours by grabbing it with your hand, implying the tractor is running or do you have a PTO that turns without the engine running?
TAT??, maybe tat2z1969? wrong, you have me confused with my uncle. Maybe to your disbelief, but more than one Jim in western PA owns a JD60 and lives on a farm.
