HYDRAULIC RADIATOR FAN MOTOR

[FRED MASINO]

I'm searching for o-ring sizes and replacement parts for the Sauer Danfuss hydraulic motor that runs the cooling fan for the radiator, Model # TAM22-90/26,5C107. The motor is starting leak hydraulic fluid.

Fred,
try calling M&M (Chino, CA).

They modified my fan unit last year and seemed very familiar with it. I highly recommend them for service and repair.

What did the modify on your fan?

The fan was not actuated when the A/C compressor was on (not un-common I was told and maybe not consistent across all Alpine model years).

The modification involved solenoids and a valve to actuate the fan whenever the A/C compressor is running.

In my case, the A/C system over-heated and failed without this modification.
