Oil Charge Pumps

800-576-2492

The oil pump is the heart of every transmission. The slightest drop in performance puts thousands of dollars at risk. That’s why our new and remanufactured pumps are individually inspected by our top quality control personnel.

Trans Machine manufactures over a dozen new replacement oil pumps for Allison, John Deere, and other heavy duty automatic transmissions.

In addition, we remanufacture many other Allison oil pumps. When possible, we manufacture and install oversize gears in order to salvage otherwise unusable pump housings. Using oversize gears eliminates the need to restore the gear pocket to its original size using material build-up, sleeves, or other repairs which require bonding, thus eliminating the possibility of material separation in the repaired area leading to premature failure.

We stock many remanufactured pumps as "Rebuild Complete" items.

Rebuild complete means all of the following as required for a particular style of pump:

All parts are thoroughly washed and blast cleaned as needed.
The pump body is re-machined as needed to restore the gear pocket depth and if needed to enlarge the pocket to accept oversize diameter gears.
Worn gear journals are repaired if possible.
Gear-to-body dimensions are restored to OEM specifications.
New standard or oversize diameter gears are substituted when used gears are out of tolerance and no longer repairable.
All new bearings and pins are installed.
New bushings are installed where applicable.

Check out our complete list of new pumps and rebuilt pumps available with and without an exchange.
