We bought two Chevy Kodiak dump trucks, with large stainless salt
spreaders, from CTA (Chicago Transit Authority). Both trucks are
equipped with Caterpillar 3116 diesels, snow plow mounts, hydraulic
PTO, and stainless hydraulic salt spreaders.

Three things sweeten this deal:

*) The stainless salt spreaders will probably pay for the purchase
*) They have almost brand new Bridgestone 11R22.5 truck tires, same as
our semi tractor, where the tires are very worn
*) One truck has 9,998 miles (true) and the other has a little under
15,000 miles. I believe this, because they belonged to CTA and they
would not mess with odometers.

We have no idea whether they can even run.

The trucks, though, are not without problems. They clearly sat around
for years. The biggest problem is that there is a lot of rust on the
main belt pulleys. So much rust that I am afraid to even try to run
these engines, as the rust may shred the rubber belts.

Is there any "easy" trick to clean that rust on the pulleys off,
without taking the engine out?

Take the belts off and use a twisted/knotted wire brush on the
grooves = preferably with the engine turning. It is not the safest
thing to do - but it is likely the most effective.
