Yanmar 4JH5E motor and Ample Power 4023-S alternator

Postby tbeetle on Tue Sep 28, 2010 3:05 pm

I telephoned Ample Power to ask if Ample Power's 4023-S alternator with 2.6" diameter pulley will mount onto the Yanmar 4JH5E engine in place of the Yanmar-provided Hitachi 80amp alternator. It was suggested that I obtain technical support from the forum, therefore I'll ask the question:

will the 4023-S alternator with 2.6" pulley mount onto the Yanmar 4JH5E engine in place of the Hitachi 80 amp alternator?

My goal is to simply swap out the alternator, and not reconfigure the motor with an adapting mount. Note that I have an Emon II, the SAR V3 regulator, and have been a super happy Ample Power Customer since 1992. I am repowering and replacing the Perkins 4-108 with the Yanmar, and would like to put the 105 amp alternator onto the new motor.

Thanks much!
