1855 rear end lube pump

CDN 400 · Dec 26, 2023

Does the lube pump drive off of the input shaft? The reason I ask is because I want to start it without installing the IPTO shaft. I just finished an overhaul and want to light it before I put all the steering and hydraulic lines back on so it easier to do a retorque and valve reset.

Ipto shaft does not effect the transmission pump

Thank you very much thats what I needed to know.

Correct me if I am wrong, but the long shaft from the pressure plate that goes to the pto in the back drives the transmission lube pump on all the 55 series tractors I have worked on. It slides through a splined collar with a small gear on it. That gear works with a drive chain to turn the lube pump. We had to fix one where the drive chain had fallen off.

Any time you are doing that also run the transmission in low range.
