300 Amp delco remy alternator

Morning David

To remove the belt,there is a idler pulley in the center of the engine with an adjustment bolt (about 8 inches long) aboveat an angle.Loosen this bolt about two inches allowing the pulley to move away from the belt and you can remove the belt.

The alternator pulley is removed with a 33mm socket.(1 3/8 may be close) A 1/2 air gun with 100 psi will get it off, but don't "rattle on it" for much longer than 10 seconds at a time.

Once the nut is off the pulley will slip off easily as it is a splined armature shaft.You will now see the seal plate held on with 6 bolts,remove the bolts and the seal plate will come off revealing the front bearing. Now remove the sealcollar still on the shaft and an o ring.Scrape the seal plate gasket off the alternator housing.Change the seal on the plate being careful to press the seal in properly,if the seal surface is dry apply a thin coat of grease an the lip.Reassemble the oring ,seal collar and seal plate and pulley, washer andnut,then the belt and re-adjust with theidler pulley with the long adjusting bolt and you have now saved a lot of time and money.

Also I have a seal, gasket and o-ring kit available if you need it.
