Product Description

Product Overview

The AT101451/AT163523 Reverse Transmission Charge Pump is a core repair part for older John Deere models such as 210C, 300D, and 310D. Its mounting flange, shaft diameter, and oil port positions are identical to the original factory pump. No modifications to piping, brackets, or installation positions are required—it can be directly swapped during disassembly, significantly reducing repair downtime.

The core value of this pump replacement lies in its direct interchangeability with OEM specifications, smooth and stable shifting performance, and high cost-effectiveness. It rapidly restores transmission shifting functionality, ensuring continuous operational capability for older equipment. Regular replacement of transmission fluid and filters is recommended to extend the service life of both the pump and transmission.

Frequently Asked Questions
Are AT101451 and AT163523 interchangeable?
Yes, these are functionally interchangeable parts. Their interfaces and parameters match OEM specifications, allowing direct replacement for John Deere 210C, 300D, 310D, 315D, and 482C backhoe loaders.
What preparations are required before installing a new pump?
Drain residual pressure from the system and clean all pipe connections, filters, and the oil pan. Always replace transmission fluid and the filter to prevent old contaminants from damaging the new pump.
What is the mandatory procedure for the first startup?
Manual oil priming and bleeding are essential. Fill the pump with fluid and rotate the drive shaft by hand 2-3 turns to expel air. Idle for 10-15 minutes and check for leaks before resuming full operation.
What causes slow gear shifts or insufficient pressure?
Common causes include worn internal gears, aged seals, clogged inlet lines, or dirty filters. Troubleshooting should start with checking the oil level and filter element before inspecting the pump body.
How can I extend the lifespan of the transmission pump?
Replace transmission oil and filters every 500-1000 operating hours. Avoid mixing different oil brands and ensure all connections are tight to prevent cavitation and seal damage.
What should be done if the pump makes abnormal noises?
Abnormal noises often stem from shaft misalignment, incorrect oil viscosity, or trapped air. Check the coupling calibration and perform the bleeding procedure immediately to avoid internal damage.
