Small Alternator for under the Hood installation

Posted by BIG JOHN on November 04, 2003 at 14:26:17 from (205.188.209.82):

I see the Mike J is asking about this so thought it might just be time to put this on the board again.

I have been putting this small alternator on several tractors, replacing generators under the hood.

It is a Hitachi #14231 which was used on 1978-79 Nissan 620 pickup with a 2 liter engine and a 1980 Nissan 720 pickup with a 2 liter engine. At NAPA it is part #2138130 - cost is right at $50 + core.

The alternator is 4 1/2" in Dia. and 7" in length and will go right on the orginal mountings on the tractor. Use an 8" x 3/8" bolt and some pipe for spacers. Being Hitachi means that it is METRIC. You will need to drill out the mountings to 3/8". The tension adjusting bolt is also metric thread.

The alternator is a three (3) wire set up which can be converted to one (1) wire. There are spade conections labled S & L and a BAT post conection. The L spade is for the idot light and can be disregarded. Use a jumper wire from the S spade to the BAT post and you are good to go.

The pully is a split type that you can widen using a spacer (once again metric). You will need to use a disc type lock washer and some locktite because there won't be room to reuse the split lock washer that comes with it.

There is a built in regulator and a resister to keep the battery from feeding back to the alternator.

This is a sweet fit under the hood that I have used on H's, M's and W models, also Cubs and many others.

Hope this is of some help.

GOOD LUCK
