1948 Oliver 60 adjustable wide front end engine rebuild info

Postby tractorman7788 » Sat Jul 11, 2015 1:04 am

I'm looking to rebuild the engine in my oliver 60 tractor. I would like to bore out the sleeves and install some larger pistons in the engine. i was wanting to know what the difference is between an oliver 66 piston and the ones i have in the 60 besides the difference in bore.thanks for any info that can be provided :wink:

I did an article for the Oliver collectors magazine several years ago on how to do that. There is 3/8 of an inch difference in the size of the wrist pins between a 60 and a 66. You want to use Continental pistons. Questions? I still have a copy of the article I think.

oliver 60 adjustable wide front end engine differences

Postby tractorman7788 » Thu Jul 16, 2015 9:47 pm

i was doing some research between the two engine and found those differences to be quite a bit. like the connecting rod being 6"long for the 60 engine and 6.75 for the oliver 66 engine aswell as the diameter of the wrist pins. i was wondering if pistons from an Allis chalmers B 125 cubic inch engine are offset in the wrist pin area or even like the oliver 60 the wrist pin diameter is .8131 for the allis chalmers and .8746 for the oliver 60 any ways i would still need to know the length of the connecting rod for the allis chalmers engine to make sure that would work, i could see boreing the sleeves in the block i have.

yes i would be interested in your article.
