Case 1070 transmission

Unless a gear in the transmission has a broken tooth (very unlikely), it should be possible to repair without any or very little disassembly, some adjustment and almost no cost except time.

You obviously know your stuff. I finally got over to the dealer and had a chance first hand to see the damage. The problem started when the "basket" that holds the fork shafts cracked in one corner preventing the detent from holding it in neutral. When the tractor locked up in both ranges in the field repeated attempts to manhandle it out of gear resulted in the chipping of a number of gears. 4th gear is the worst, completely missing a number of teeth.

It my understanding that to replace the 4th gear which is on the pinion shaft requires splitting the tractor and pulling the rear end completely apart thus a pretty hefty labor bill. I did locate a used transmission and we're in the process of ripping it apart hoping to find lots usable parts.

Unfortunately I don't have a shop well enough to do the job myself. I hope that the decision to fix the tractor pays off in the long run.

We also have a 1978 1070 Case 5000+ hrs. very well built, virtually no repairs.
Another Case 2670 we have and use as a dozer tractor broke a planetary gear in the powershift---local dealer quoted $9000 Can. to repair---fixed it ourselves for under $1000 in parts, free labor(on our own time).
You may want to consider a second opinion on your quoted repair it seems excessive.

Would you recommend looking for a complete transmission, rear end included? If so should I put the rebuilt powershift from my tractor into the replacement?

Have they got that tractor opened up so you can see the actual damage they are squealing about?

If not, this smells a little fishy to me, because to tear up those gears, you would think you would have heard it while it was coming unraveled. If it is not opened up and with less than 4000 hours on the tractor, plus the fact that you have just had it overhauled anyway, I think they are doing a guessing-jig dance with your money.

Now, I know absolutely nothing about your tractor, but I do have a shop guy here who works on 'em. He tells me that he runs into "oil apply" quirks in the hydraulic systems with these powershift tractors.

If the tractor is still in one piece, I'd be for getting a second opinion.

Just tryin to help ya,

The tractor is at the dealer and they opened up the top of the transmission to give me the bad news. I haven't had the opportunity to see it for myself but I'm planning on it. The dealer is reputable and did the powershift repair. They didn't notice, nor did I any problems with the gear transmission at that time. The tractor would get stuck in gear, multiple I now assume, on occasion. I would have to wrestle with the shift level but it would eventually come out then run fine for a while. I was surprised to hear about the gears being shot. I'm the only driver and don't recall any grinding when if finally got stuck for good. Either way it sounds like a major teardown to fix these gears thus the high price of the repair?
