Allis Chalmers loader

CCer · Apr 22, 2017

Have a loader, I think it was originally for a D-17. Can't keep lift cylinders from leaking. Cylinder barrels are visibly swelled. Need a loader model number to look for parts. My tag is missing. I think it was on middle of front cross bar. Can anyone help?

Is it a "trip-bucket" loader with one-way lift cylinders?????????? or is it a hydraulic dump bucket with two-way cylinders on boom and bucket ???

It is all hydraulic, two way cylinders thank you.

Should be a model 400 or model 500 loader. Seal kits are the same for all four cylinders.

I wonder if the cylinders were designed for the newer D-17 Series IV with the low pressure/high volume hydraulic system and were used on one of the earlier high pressure/low volume systems?
I've often wondered what would happen in that situation.

Low pressure in a high pressure cylinder doesn't hurt anything. High pressure in a low pressure cylinder can blow one up. I stroked out a 2x8 low pressure cylinder numerous times on a WD and never hurt it. That next time though...
