I did try a flow reducer valve, but I think I should try one like I have on my 446 I use for tilling. I would have to plump the return to the reservoir, but that shouldn't be a big deal...The way the stack is plumbed it has the pto in both sides, so when it is on, it can flow through, if that makes ...

I had thought of tapping into the three point circuit for mine, as I believe it has lower flow? I have tried flow limiters, but the difference is negligable at best. I'll have to see if I can find specs on the original pump, and such. Maybe I can run a hydraulic motor off the PTO for it's own pump? ...

Here is a pic of the tiny backhoe:

I think this is the section I should post in. Guys, I have a tiny backhoe that came off the smallest excavator I have ever seen. (It was a SS16 by Kobelco) I have fabbed up all the mounts to put it on my 646, but the hydraulic feed from my PTO is way too much pressure, I think. It is super jerky, to...

This is my second 646. My first one was a complete basket case also. The loader had been cut off of it, and the arms were cut forward of the cylinder attach points, engine had pitting in the cylinders, much of the three point was missing, and the only two cylinders it had were the three point, and t...

Yes, when I decarboned the heads, I saw that the pistons were marked with .030 on top. There was no ridge.I may just pick up those pistons you linked to. Seems parts are often hard to find for these guys.------Metalguy

Been a while, but I have the engine installed, and running pretty well. Sadly, it does smoke some, probably worn rings. It has .030 over pistons. Are rings readily available for this? At any rate the 646 runs, drives, stops, starts, and digs like only a 646 can. ------Metalguy

I think I will drill aq hole through the wheel, and shaft, and put a through bolt in there, cinching up the crack. My newly aquired one has that already done to it by a prior owner, and it seems to work well. -----Metalguy

Hey guys, my 646 (1973) now has a cracked steering wheel hub. Under difficult steering, it will "skip" on the splines now. What I want to know is, has anyone found a good way to repair one? I thought about perhaps drilling , and tapping for threads to pull the crack together, but wanted to...

I used the set screw, and also fabbed up a stepped washer that allowed me to install a bolt into the end of the crank as well. The engine is now setting in the 646, and only fuel, and wiring to finish up! ------Metalguy
