Fw: Re: [cal] Alternator Replacement Question
Thought I'd forward to the new list to see if Tom or any body else had any replacement part/model number(s). It's SEV Marchal, 35 Amp, single 2" foot, 3/8" drivebelt off a 1979 Volvo Penta MD7A, and I'd like to replace with 70-80 Amp one I can get at an auto parts store.
Thanks...

Tom,
Thanks very much. I'm having a little trouble with my local auto parts store because they can't find anything without a auto make, model, year. I have found a lot of info on the web on the Leece-Neville ones, do you have any part number that would help? Also, is a 100 amp one too much for my 3/8" drive belt?

Hi John,
There are several alternators that can be made to fit. My preference would be a 100 amp Leece-Neville, (L-N). You can modify the bottom bracket by turning a spacer or using several washers. It is very important to assure perfect alignment of the pulleys.
I have used a internally regulated L-N's on my Perkins 4-236 and on my Yanmar genset since 1989, over 6,000 hours on the genset and 3,500 hours on the Perkins. No problems, yet, but I carry a spare just in case. These large L-N's are the type used on large trucks, ambulances, fire engines and police cars, so they are stout and well built. My local NAPA store has them, rebuilt for less than $200. I do not like the, supposed "marine type" souped up, small frame alternators like Balmar. They do not dissipate the heat adequately in a small engine room, so are short lived.
Hope this helps.
