Lycoming engine questions/IH truck

Postby birddog » Mon May 07, 2012 5:58 pm

The unit that appears to be the original generator is gear driven. First question, does the drive gear on it have anything to do with the timing? It looks like someone removed the guts to the original generator and then mounted another generator to the frame rail. Second question, is the pulley on the back of the original a modification they made to run an add on generator or was it part of the original, in order to run something else? ( if so what? )

The tag on the generator reads as follows.

Another question, just because, when did Remy become Delco - Remy?

My guess is not - just not logical to have to retime the idler and cam gears if the generator were removed and the engine rotated a bit.

You will have to get the engine manuals to double check. My guess is that the generator is powered by an idler gear or the cam shaft gear. Similiar to the hydraulic pump on the Cub. Could also be driven by the flywheel - hard to tell exactly where the generator is located from the photos.

Where does the belt go to? My guess is that the generator is original to the truck.

Gear driven generators were not uncommon, that may be all it is. However, my old IHC truck had a gear driven generator that had the distributor mounted on the end of the generator. The engine spun the generator which spun the distributor. Where is the distributor on your truck?

Thanks Eugene;The distributor is on the right front of the engine a little below and to the right of the cam pulley. ( the cam pulley runs the fan )

Thanks Landreo; You can't see the distributor in the picture but it is mounted vertically on the same housing right behind the coil.

Because of the location of the cam, distributor and the generator is why I was wondering about the timing. It looks to me that the generator should be far enough right not to be a factor, but you never know.
