My 8652 F-3 just stripped a gear. Did any MPC diesels have metal gears? I am thinking about swapping the trucks out if possible with one that has metal gears. Is this possible?

It's possible, but not necessary.
Check the parts list(s) for the 2243 and order the corresponding metal gear to replace the broken nylon gear.
I believe that did change over from nylon to metal in the early 1980's. For example, I have a GGI from the late 70's with nylon, and another GGI from 1981 with metal.
MPC went to metal gears in later years. A metal replacement gear should be easy to fine.
MPC used the same power truck on a number of engines. Replacing the gear should not
be too hard or just replace truck with a truck with good metal gears. The parts are
not hard to find at hobby shops or train shows. You may have to call around.
Paul, contact Lionel they have a metal replacement set for that.
TM actually did a segment in Lionel Nation 7 about replacing the motor truck of some MPC engines, like the F-3's, EP-5's, and the Virginian E-33. The benefit is not just replacing the plastic gears with metal gears, but also gives the engines Magnetraction equipped axles. It's just a matter of removing the truck frame on top from the MPC truck and placing it on the postwar version.

If you see that as a benefit...
The dual motored Fundimensions F3s with traction tires - like the New Haven 8851/8852/8864 set, were some of the best pullers ever.

What is their number?
Lionel's number that I have is 586-949-4100 and they will take good care of You.
That number isn't working, it just says it needs a one and an area code.
I called a different number on Lionel's website. The kind lady on the phone redirected me to Brasseur's Electric Trains. I shot them an email and hopefully I can get this fixed!
I replaced the MPC trucks on my Virginiaan rectifer with a post war power truck.
Easy replacement and world of difference in operation.

The 586- part of the number Larry gave above is the area code.
So you'd dial 1-586-949-4100. Need to do that when dialing a number that's outside of your service's area code (long distance calls). 
The 586 area code and the number is all wrong, they are in North Carolina now. If you need a truck with meetal gears, email me in my profile...
