JD 4020

LarryH · Oct 17, 2014

I need help with a JD 4020 LP. I am looking for a rebuild kit to go from a 340 ci to 360 ci. Does anyone know where I can locate one?

You would need a crankshaft. The later, larger engines had a quarter inch longer stroke. Mike

I put an overbore kit from M&M in a 105 gas combine engine that supposedly turned it into 362 cubes. It did have more badly needed grunt with the increased cubes. M&W is no longer around but I'm sure there are overbore kits out there for ga. LP might be another breed of cat. Jim

Ditto what Mike stated.
