Title: Can you identify this engine?
Post by: Jeff Obermeyer on February 18, 2008, 06:37:55 PM
Hello everyone,

I picked up this Fox engine and was wondering if anyone can help identify it. In each of the three pictures it is the one on the left next to the Fox 35 Stunt (placed for size comparison) the mounting holes are different than the .35 and the bottom of the case is larger. I'm guessing it is a .40 but not sure which model. Any suggestions?

Thanks for your help!

Its a plain bearing .36. They're pretty powerful too.

They also like to throw cranks.

It's a 1974 version Fox 36 bushing, Fox cat. no 13600.

All Fox 35s started out with the same mounting bolt pattern.  The cases on the 1960 needle bearing combat specials, the ones with the removeable front ends, were pretty weak.  By 1962, Fox made the bottom end of the case thicker, thus inceasing it's outside dimension and the bolt pattern width, from 1 1/2" to 1 5/8".  There after all the 29Xs, Rocket 35s, 36s, and combat specials have had the wider case and wider pattern.

  That engine was also produced in the .29 size.  If it is a 29, it should have 29 stamped to the top side of the left hand mount lug.  29 or 35/36 sleeve will drop right in either case.

What do you really mean by "throw a crank".  I ran several of them a lot and never had a problem.  I did have one eat a bearing up on "kool aid fuel" though.
