Time to change the clutch

mffarmall · Dec 9, 2013

Hi all,

It's almost time to change my clutch. I have three basic starting questions. Followed by a lot when I get started.

1. Where is the best place to get one from, is their a better off brand then stock?

2. Are their any special tools other then a gear puller needed, or tools that help with a part?

3. Are their any hard adjustments other then checking the pedal clearance and bolt behind it, making sure the fingers have enough clearance?

If your clutch is slipping, either the clutch is misadjusted (not enough gap at the fingers), the clutch is contaminated with oil, or you need a new disk. The clearance is adjusted not at the stop bolt, but either by adjusting the length of the link rod between the clutch pedal and the fork, or by adjusting each of the three fingers at the bearing.

For replacement, you don't need a gear puller, at least not on my Jinma 354. You do need the clutch alignment tool that Tommy from Affordable sells. I think he's the only source.

I detail the process for my tractor, including all the required tools. Yours will be slightly different but the general principal is the same.

Hi Mffarmall. We will have all of the parts you need to change that clutch in stock. I can also walk you through all of the adjustments over the phone. It's not a tough job and since it sounds like you have done one before you shouldn't have any trouble. The two adjustments you mentioned are the main things you will want to check. Let me know if I can help!

We also have any of the parts you may need including the Splined clutch alignment tool, we give that to you free if you buy the complete clutch assembly from us, which you will want to have for sure.

Let me know if we can help you

Absolutely get Tommy's clutch alignment tool. It is remotely possible to get a two-stage clutch together without one, but it will be long hit-and-miss process filled with frustration. With an alignment tool it is a snap. I split my tractor for a different problem, but it still involved tearing down the clutch pack and so was no different than replacing the clutch. You canread about my process here:Major Tractor Woes in Paradise | CHINESE TRACTOR WORLD FORUMS. Tommy was a great help to me with advice and parts I needed. At the time I did mine, Tommy hadn't quite gotten his alignment tool to market, so I made my own. I have a lathe so it wasn't too difficult to make, but I'd have bought one if I could.

Looked at the clutch. Is it just a pain to replace the disks. Is it better and faster to just change out the entire clutch assembly?

mffarmall · Dec 15, 2013

What would be the assembly that I would need the 8 or 9 inch. What numbers to you need. The engine and the tractor or year?

I just went out and gave the clutch every chance to work that I would think of. I tightened down the front until it was almost touching both plates. I also let out out pto springs as much as possible. Then I pushed the bolt all the way in, and pulled the peddle in as far as I could. I checked and there is nothing left but grinding. It has given it's life.

I believe all that blind wrenching has truly screwed the pooch. On these Chinese two stage clutches, there's a definite sequence to follow - which is difficult at best to perform through the inspection window. If the tractor is still split, you might be able to be talked through the realignment process. My recommendation is to buy an entire new clutchpack with both throwout and pilot bearings. Don't assume the clutchpack will be ready to mount right out of the box. There are a few gaps you might have to correct before mounting. Then you can rebuild the take-off clutchpack at your leisure.
