[Frank Sorbello]

I need to replace my hydraulic cooler fan for my pt-422. Anyone know a good source for replacement?

thanks,
Frank

Several folks have said auto junk yards.

This is where I bought mine:

JayCorp Technologies - SPAL 7.5" Slim Fan

Not cheap... but this is the same size and brand that I have on my hydraulic cooler for my PT422. YMMV.

Ebay has fans cheap that you can use.

Thanks Tim, The fan I have looks the same but is an 11.5" or 12" fan. They have two types, push and pull. I am confused. I want the cold air to be pushed on to the cooler, right?

If yours is like mine, it is a pull fan (mounts on outside of cage, pulls air out).

Yours is probably this one (11"):
JayCorp Technologies - SPAL 11" Medium Profile Fan

or this one (12"):
JayCorp Technologies - SPAL 12" Medium Profile Fan

Purchased two 12" fans off ebay for $34 and free shipping. Look just like the original, except two of the four mounting holes don't match up.

Fan is not coming on after running hydraulics for a while. There is a oil cooler thermal relay in the manual. How do you check to see if that is working properly? Is that a common part or something I need to go through PT to get?

Thanks

First, make sure the fan works with 12V across it.
If fan works, then,
Suspect the fuse for the fan.
If fuse good, then,
Suspect the thermal relay.
Put a meter on it. It should be open when cold.
Run up the tractor for 20-30 minutes and put a meter on it again. If its still open, its probably bad.

Mine went bad about 5 years into ownership. I just bypassed it and hook the fan to 12V directly each time I run the unit. Someday I'll repair it, maybe.

Put a hair dryer or heat gun on the thermal switch.
