I've got type KS motors from International Projector Corporation attached to SH-1000s.

Couple of questions... the manual says to give each of the two "grease cups" a 1/2 turn monthly. This iteration of the motor does not have cups, but standard injection nipples. Anyone know what 1/2 turn would mean in terms of volume?

Oddity question... the motor has a flywheel guard with an reservoir that drains via a petcock. What the heck is it for? Was the outlet of the valve somehow attached to the sound head to fill the latter?

Hi David:

The grease equivalant would be one pump of a standard grease gun.

And that reservoir and valve were there to catch the oil from the projector head..the Supers and E7's had a metal catch plate that mounted between the projector and sound head to direct the oil to that reservoir.

If the motor was rebuilt almost every modern motor shop would have replaced them with sealed bearings

Tony, thanks for the info.

Nice to know the reservoir is vestigial. I figured it had to be a catch basin, but wasn't sure what it would be catching. [Wink]

Gordon, I'm pretty sure these haven't been rebuilt, given the condition everything is in. I've got an SH-1000 and motor out being rebuilt now. I'll have to find out how they're handling the bearings.

Probably a good idea to replace both bearings with shielded and carefully clean the old grease out. Remove the grease cups and replace with plugs.

Good idea, Dick. I turn the motors over so that the holes are on the bottom after removing the unnecessary grease.

In my life, I've never seen that motor with something other than sealed bearings. Much grease, however. The grease being the main reason that the motor failed. Louis

Hmmm, is this something a person with good mechanical skills can do? Or should I leave it to the pros? I wouldn't touch in any case until my 2nd SH-1000 and motor are back in-house.

David, not a difficult task, but one best left to a motor shop, they will have the proper shims on hand to get excess end play out of the rotor assembly, and can make sure the rotor is dead center in the field, critical to prevent hot spot damage to the windings.

That said, I have done it myself with good results.
