Small Alternator for under the Hood installation

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

Please post any other questions and I will try to answer them.

I have also used this alternator on A's, B's, C's, and Super C's. To my thinking the smaller size looks much better hanging on the left side than one of the bigger ones. Just my preference.

GOOD LUCK
