Vickers V20 Hydraulic Pump Replacement -
[email protected] - 08-20-2026
So I just finally got around to replacing my hydraulic pump on coach 490. This pump is a venerable Vickers V20, the chevy small block of hydraulic pumps. It started leaking and leaving a spray of hydraulic fluid in the engine bay. I tried replacing an internal o-ring in it and it did not change anything. I am also getting some whining when the fan comes on along with some groaning and moaning from the steering box. Not sure if either of those will be cured with the replacement of the pump but it needed to be replaced anyways. I am going to tear down the old pump and see what it looks like. I am guessing its going to be worn, especially since it appeared that the hydraulic filter had never been changed, or it had been a long time since it was changed.
Here is the pump, its a Vickers V20 #V201P11S38C11L:
Here is the hydraulic filter that fits mine Wix #51756:
Here is my video of the project:
