B model generator


Recommended Posts

Anybody out there have a GOOD B model generator that was equiped with power steering that is for sale? The PS pump mounts on the back of the generator. I would even buy just the correct armature if its a good one. Thanks

I have seen those at truck shows but I can’t think of anyone who has one ,, I’m sure they are out there,, I’ll keep my eyes open for one, I know a guy who has a few old Bs junked ,, I’ll ask him . I have an air compressor for a 673 with a PS pump on it.

the air compressors with PS mounted pumps were  and to a point still are more common then generator mounted PS set ups. not doing any good today, back in the day I did see the generator set ups which even then weren't common. due largely to fact PS wasn't a standard item .  men were men and drove Macks LOL

The pump mounted on the air compressor might be the way I have to go. A few people have suggested mounting another pulley on the crank and mounting a belt driven pump up on the engine. Not sure, because I have not done a lot of investigation, but it looks like and extra pulley would push the balancer out to far and it would rub/hit the radiator. This is on a B61 and there is not a lot of room between the balancer and radiator to begin with.

seems conversion to air compressor /PS combo would be way to go. parts availability should be better, even to find generator/PS combo would be nice for originality ; replace /repair down the road will get worse before better. air compressor set up might prove to be a better system for operation also. eventually changing over to an alternator will put you back to square one with the generator set up tooo.

Was the air compressor with the pump mounted on it a common Mack part? If so what years should I be looking at and are the air compressors fairly standard to bolt up to a 673 engine? Thanks

Most of the Bendix Tu-Flo type compressors were available with an open back for a P/S pump.  So were a lot of Mack branded ones.  Do you know what compressor is on there now?
