Robert_in_NY,
I have a Chisholm Ryder and pick grapes (not much, prob. 150 acres total- I do custom harvesting too). It's actually one of the first ones brought to Washington state, from what I've been told. I'm guessing it was one of the first 5 machines here. It's a 1968/1969 model year based on the SOS ID numbers. And it's been picking grapes ever since then..... I'm the 3rd owner- well 4th if you count the guy the original owner had to repo it from.
And her top end has been completely rebuilt. I posted here last year on the saga of changing an engine up top. The old 3000 diesel was worn, compression was WAY below spec- and upon inspection of the engine, a wrist pin had come loose also- left a nice scratch in the bore (or maybe in the past and someone just let it go- not sure). Any how, she has a Ford/NH 4630 engine in it right now (so should be about 50-55HP at the PTO) and a fresh rebuilt SOS (the old one had input shaft wear and it turns out, the PTO clutches were going bad- they found out when they took her apart).
The place I got the tranny rebuilt has a great reputation. The gentleman that owns/runs the place was a former Ford tech (mechanic) back in the early 1970's. As he says, he was sent to school by Ford to work on the Select-O-Speeds. Here's his website:

They 'always' have a SOS tranny instock....for those times during harvest when a picker goes TU. Last year, I ended up buying their tranny before the season started (so they were w/out). The machine came w/ a spare (suppose to have been rebuilt), but after getting it install w/ the new engine.... somethign went wrong. Turns out someone forgot a small part in the bellhousing, so that's why the small oil line came out...forgot the retainer of all things! The other thing was, the PTO clutches on that spare went were bad. Who ever fixed it before only looked at what was broken...didn't inspect the whole tranny.
Ask your friend if he's done any business with DW's Motor Machine- Located in Grandview, WA. From what I've heard, people from all over the country seem to call on him for parts.
Oh, also, would you mind asking your friend if he's ever had any lower axle issue with his Chisholm Ryder. From what I have heard, some machines always have an issue w/ breaking axles, while others have not. I broke my first this year... but the last owner, I know of it breaking at least 2 other times (once while they were harvesting at my place a few years back). I'm just wondering what folks in your area are doing for parts or if there is anyone else besides DW selling parts (lower/upper axles I'm wondering). Those axles are all custom built now..... Better to have lots of options.
Too bad no one from California frequents this section. I'm wondering if anyone does stuff for these old beasts there......
(I know of two other Chisholm Ryders for sale here....one has the International Hydro tractor on top and the other is a Ford unit. But overall, there are TONS of Chisholms here still. Some are still being brought up from California to replace worn out machines- I say abused machines.)
