              Qualified oil seal TCM919772 supplied by Dongfang yoyik

The skeleton oil seal TCM919772 is a combined hydraulic seal, which is mainly used for the overall seal of the EH oil circulation pump, and is a frequently used accessory during power plant maintenance.

As an important sealing part of the oil pump, the skeleton oil seal plays an important role during the normal operation of the pump. The sealing of the entire pump body must rely on the skeleton oil seal

Replacement method of Skeleton oil seal:

1. Separate the circulating pump from the motor.

2. Completely disassemble the circulating pump.

3. Replace the skeleton oil seal and reinstall it.


1. When disassembling the circulating pump, it is necessary to prepare the necessary tools for the smooth disassembly of the pump.

2. To replace the skeleton oil seal, it is necessary to soak the oil seal in EH oil for 5 minutes to achieve proper fit.

3. Try to choose a clean place to avoid polluting the remaining EH oil in the pump.
