For my 149, need Hydro and Rear End advice

Good to see someone doing hydro rebuilds despite the fact that it seems frowned upon... not sure why, there's an entire section in the repair manual dedicated to hydro pump maintenance

If you priced a NEW "replacement piston Assy" or was lucky to find one, you would not have purchased it as they are quite pricy.
As far as mixing pistons in the bores:
it will now be noisier that it was before they were mixed, lucky they were not worn bad.

I should clarify that you don't want to mix up parts from the pump side and the motor side. Port plate and usually the barrel and piston slippers are different, even though that difference is not easily seen.

As for a hose supplier, I'm several thousand miles from Alabama, so I wouldn't have a specific recommendation. But many industrial suppliers make up common hoses and these are not high pressure. Just take your old ones with you.

Tractor supply sells an assortment of sizes/lengths, also was making custom hoses but don't know if they still do.
Napa in my rural area makes hoses also.

Yeah, no wonder I couldn't find any for sale anywhere. Realistically I coulda bought another pump and stolen the parts from that, but at that point I may as well just swap out the whole pump. I guess it could have been done for the sake of keeping the whole rear end original, but still too late now! That whole rear axle is completely dismantled at this point and I don't have any intent on putting it back together any time soon, I also don't have the gasket set. Not that I can't do it, I just don't need to. And it's much easier to store.

I guess really the only thing I was frustrated about was the simple fact that when I wanted to rebuild mine everyone said "just buy a new one" but then a year later this guy does it (still a great job, and I hold nothing against you for doing this) and everyone is fine with it, I don't believe I saw a single person suggest replacing the pump in this thread.

Like I said before, not much I can do now. And the 107 runs and drives anyway, even without the original hydro, so I'm happy!

CC 107, the biggest problem with the ag industrial supply is "intentional proprietary" manufacturing and labeling. That is having a product made just slightly different then the norm or simply having their own numbers attached.

It may be difficult to source internals for a CC 149 hydrostat, but for a shop like I worked at, it would be no problem to cross it over to a readily available model. Sundstrand (Now Sauer Danfoss, I believe) still sells all the parts, but you better take good care of the case. Very, very few shops will look beyond their own parts lists and dealers certainly will not. Dead end.

And rebuilding VS buying new often comes down to labor. At shop rates of anywhere from $80 to $180 per hour, it won't take long to overcome the price of new. But a careful and reasonably competent home mechanic can still save a ton of money. Whenever we advised do-it-yourself'ers, we had two minimum goals for them. Take it apart without breaking anything and getting it back together exactly as it came apart. Same oath as for doctors: "Do no harm."

Google; Pioneer Parts Rebuilding in Prince George BC for a look at a well equipped hydraulic repair shop.

Well, I am certainly no expert on hydraulic systems, but I do have a decent understanding of the Sunstrand hydro units, how they work, and how to disassemble/reassemble them. I don't doubt that I could probably do a rebuild with little to no issues.

Straying away from my 107, my 147 project tractor, might be worth it to open up the pump, and make sure everything is good in there. Replace all the seals and gaskets, clean up any gunk, etc. It did sit outside for like 15 years, and it seems to make a strange sound when you push it manually. Main difference between this one and the 107 is that this one isn't blown up!

I might have to look into a rebuild on my 147's hydro for the sake of making sure nothing is wrong or damaged. But that will need to wait until I finish with the engine
