I would start with simple green or 409 de-greaser and the hose hooked up to your hot water. Clean and try to get a better idea of where the leak is. Maybe lift the bed up after you cleaned it and its dry, start coach and take a look? Go from there if your a do it yourself person as I am. You may want to try to find the motor make and model. You can also search this forum for ideas. Post what you find and this group will point you in the right direction. I had a 2000 alpine too. Loved it.

Thanks for or help.

Sauer Sundstrand motor.
Tam 22-90/26.5 CI 07 RUL E/OB
Date code 00C01
Type 551101143170

Determined leaking between motor switch valve and motor housing is the suspected area. All hose fitting dry, fan shaft dry.only area wet with ATF when engine running is between switch and motor housing.

Now looking for a lead for rebuild or replacement. Is their anyone in the Seattle area? I can't seem to find anyone with knowledge these motor assemblies.

Another area of my concern is a broken motor valve switch cap plug that I found broken.

Is there a supplier that still supports these Tam 22-90 motors.

Will post few photos.
Thanks for everyone's help

Few photos broken switch
Valve cap, this is a concern.

Have been told there is a "O" ring between the valve switch and motor housing that is most likely cracked causing the leak.

Unfortunately Allen screws holding everything together are seeded tight.

Concerns of thesnsnapping then will need machine shop work.

Any one know of a good machine shop where a can have them turn a new cap bolt and if needed drill out a few broken Allen bolts if they shear off during removal.

Update on Hydraulic fan motor; found a seal kit from White House Products LTD
in UK. Kit # 5SMLGO1143002. Received the kit in 3 days at a cost of $85.21 + FedEx Priority shipping, $23.99. Disassemble the motor and found a damaged hydraulic plates and seal. This damaged was caused by an empty plastic trash bag wrapping around the fan shaft and causing the fan to become unbalanced. I had to order a new motor from White House Products LTD. Part # 5SM/42050CC. The tag on the motor said it was a Dynamatic Limited UK, type 551101299170. The stamp on the motor said made in Italy. No need for any modification, this motor was an exact duplication of my old motor. I received the motor in 3 days at a cost of, $665.28 + FedEx Priority shipping $69.04. US Companies wanted twice as much and as long 13 week to receive the motor. If anyone needs a pump motor they have it also. Thanks to, White House Products LTD in UK (tel# +44 (0) 1475742500) they made this repair very easy. Call them.

Whitehouse is also the goto company for the fan/brakes/steering hydraulic pump. When I bought my pump I ordered it on a Thursday morning and it was at the shop here in So Cal the following Monday morning. Pretty darn good service as far as I'm concerned.

Shops here in the states were telling me 8 - 12 weeks to get the pump!!
