825i Constantly Jumps Out Of Gear

I have a Deere 825i that consistently jumps out of gear. I eliminated linkage as the problem by disconnecting it, and manually selecting each gear to the detent position. Low and reverse hold fine. High jumps out with anything more than the slightest amount of acceleration or the smallest amount of incline.

I'm pulling the transmission, but still waiting for my service manual to arrive. What's the trick to removing the inner secondary clutch sheave?

The service manual will have very little on clutches- It sounds like your primary needs to be re-worked. If you are removing the spider you will need specialized tools. 3/4 drive breaker bar and torque wrench- spider nut socket- clutch holding fixture- large bench vise ( must hold clutch fixture tool and up to 300 ftlbs of torque) See attachments.

If you don't have these tools - it would be far less expensive to look at the Handfitted clutches by MBDiagMan . He does an excellent job of Re-working clutches. Perhaps he could re-work yours?

On Edit: I didnt understand or read the original post correctly-- sounds more than the clutch...good luck

If you said you had trouble shifting I would consider the primary clutch as a problem but it has nothing to do with your transmission staying in gear or popping out of gear under load. You will want to remove the secondary/driven clutch to get at your transmission. Luckily it can usually be removed without a clutch removal tool.

Yeah, it's not an issue with the primary or secondary clutch, however I need to pull both to pull the transmission. What's the trick to removing the inside half of the secondary? Mine seems to be pretty tight on the shaft.

Have you tried any of the freeze off products? I have used dry ice - on other applications with amazing results...

I haven't since I wasn't sure how it was supposed to come off. Is it supposed to just slide off once the bolt is removed? That is what I'm familiar with for most secondary clutches on snowmobiles and ATV's.

I have seen a secondary clutch removal tools advertised on EPI's website for older Polaris's- but I didn't think you needed one for a 825i

If it's a pre-600000 serial number 825 with original clutch, you can fashion a primary puller with a 9/16"-18 bolt and a rod or cut off bolt for a shank to transfer the force front heed of the bolt others ofthe crankshaft. Make sure the bolt engages as many threads as possible and lubricate the threads.

If it is a late especial number, you will need to buy the puller,because it is a very fine thread and you really need to be sure you don't strip it.

Hope this helps.

For anyone following or finding this later... the service manual came, and I confirmed the secondary clutch just slides off the shaft. Turns out it was only mildly tight and light pressure behind it with a pry bar easily removed it.

My primary clutch puller did not arrive yet, but I was able to pull the trans with the primary still in place. Pulled it apart and found the failed shift collar and mating high range gear. You can see evidence of the wear caused each time it jumped out of gear and ground to a halt.
