Fan blade trimming

[coldtaco]

One could also try balancing by placing assembly on some sort of cone or triangle to check balance and trim as needed. But that would probably be going overboard.

Most people probably are not into it but 90% of all tropical spec 70’s I have seen have no fan clutch. They run a direct drive fan. Everyone I have seen also runs very cool 24/7.

You can still get the fan hub without a clutch.

The 1993 PZJ75 that I drive in the PI was ordered for the Philippines climate by the Fire Dept and does not have a fan clutch.

So the truck actually ran about 10 degrees warmer with the new fan and Tridon t-stat.
Anybody l ow what the temp rating is on these for sure? I assumed it was 82 celsius, the same as what I took out.

I have found that thermostats usually come in two or three temp ratings.

I am going to have to confirm the temp rating on the t-stat.
