will a late john deere A block A3703R work in my 1953 jd 60

 

[Mike Aylward]

The block will physically fit but will be lacking the two mounting holes at the bottom for the frame bolts. Otherwise they are interchangeable. Mike

Mike, the A3703R block is the same as an A4320R block as far as mounting holes. you must be thiking of the A3462R block. Roger

 

[Mike Aylward]

Hi Roger. The later 4320 block has mounting holes on the bottom side that go up through the frame on a 60. These holes are not in the 3703 block. Otherwise they are the same. The later 4320 block was the factory replacement for A tractors above serial number 648,000. Mike

Yes, the crankcase end is the same. But like Mike said, on a A4320R block there are 2 holes on the bottom, about 1.5"ish back from the deck for a 5/8 bolt to go thru the frame on a 60 into the block. The A3703R Block doesnt have these bolt holes, or previsions in the casting to add these bolt holes because a late A didnt have frame rails under the block for said bolts to go thru.

Mike, sorry did not think of vertical holes! but you would be fine without using them most of them i remove don't have them there anyway. Roger
