Hi,

Anyone know of differences between a B43G & B48G that would cause problems when changing out a B43G with a B48G on my 318?
I checked the JD Parts catalog and the one area I am not sure of is the PTO end of the crank. The B48G was used in the 420 and it used a dual pulley PTO. Is the crankshaft length the same?

John,

Thank you for the info.

Bob- It's an easy straight across swap, you should be able to do it in an hour. The only difference I had in mine was I used the 318s starter on the B48g
