The early Chisholm Ryder's w/ the 3000 were underpowered according to the guy that I talked to the other day. If you had any type of incline (hill), it taxed the engine. The 4000's did better, but most who had them were pushing the limit still. Heck, I remember that when it ran into mud in the vineyard, they had to shut off the PTO/hydraulic system to get enough power to drive out.
The repair shop I talked to the other day had a 4000 engine available for rebuild. He estimated $3500 to rebuild that engine, since it was an older one that was RnR-ed. And I'm not sure if that includes installing it up into the machine. A lot of people pulled out the 3000 engine and swapped to the 4000 according to him. I guess I'm just taking it one step further....
While I was at their shop the other day, they had a newer harvester (4000 on top) that they just "fixed". The owner purchased a rebuilt 4000 tractor w/ the SOS tranny and told them to swap out the 4000 that was on the harvester. So they split the tranny and axle and put it up there.....
I've thought about taking the spare rebuilt SOS I have, having that shop look at it and then installing it w/ the new engine. Just in case the "current" SOS might have an issue. It was just a thought....
This machine has been picking our grapes since my father asked the original owner back in the early 1970's. It was sold twice by the original owner (original 2nd owner ran it, but missed payments, so he took it back). The "2nd" 2nd owner ran it for years and I bought it from him. So technically, I'd be the third/forth owner.
I plan to keep the old engine. Sentimental value (core is only $800). I'm friends with the original owner's grandson (never knew him as a kid, only met him at the local community college when we both went there). I'll put it back together after I pull it down for storage. Plan on rebuilding it eventually....maybe to put it into service as a stationary motor (if I can find the PTO setup for them).
(I'll grab my digital and take pics of my machine/engine and post them.)
PS- I'm told the 4630 engines have 'real' glow plugs! I suppose that harvester will be working for another 30+ years after this refit...... Gotta give them credit though....its been running for 38 years, well over 12,000 hours.
