Ruckstell P147 notch plate spacer ring Why?

Post by Mark Gregush » Tue Nov 12, 2019 12:09 pm

When I got some Ruckstell part these were with the group. The notched ring was glued to the P147 notch plate with old grease and the notches line up. Any ideas why and what it would have been used for? Was it something used as a spacer between it and the thrust bearing on the early ones? It is approx .190 thick and the two parts have become somewhat magnetic.

It's nothing that ever came from Ruckstell. Probably something to be able to use a thinner bearing or to take up the wear in the case somehow.
More thought required.

The thickness is somewhat close to that of a typical bronze thrust washer. Could this be to take up the gap of a missing thrust washer? Obviously, it would be the wrong thing to do, but an unknowing past tinkerer may have seen it as a solution to an odd gap that he couldn't explain, seeing as how a "babbitt" washer may have disintegrated without a trace. Just a thought...

Stan I was thinking along the lines of worn case too. Jerry it would move the ring gear the wrong way.

Mark: This is just a guess; the notch plate has a lot wear on some teeth and if the sliding clutch teeth had even more wear then the Ruckstell was probably popping out of gear a lot, bad news. If better parts were not available then moving the notch out a little but keeping a place for the lock screws to catch it allows the sliding clutch to engage the bad notch teeth with better sliding clutch teeth.

Interesting idea. Too bad I didn't get more guts to find out.

Mark,

Yes, it definitely would. As I mentioned, it would be the wrong thing to do. That said, I like the other suggestions here better!

Thanks guys for the help. I got a case that had the axle tube cut off with them. Before I loose the spacer I will give a trial fit, that is when the rest of the parts fall into my hands. LOL

This whole unit fits into the case and the notch plate locks in with two screws. One that also holds the shift lock on and another short one on the top of the housing.

If the bearing has stuck and worn the boss that the shift plate fits into, which it can do if the lock bolts are not holding the plate, the plate can turn and wear into the case. Putting a shim behind it -- such as the piece you have here -- would move the entire unit back to at least a somewhat correct position, cause the lock plate to be in position to hold when the lock screws are tightened against it and move the ring gear against the pinion gear so it would work.

These things were abused beyond belief. Parts were not available. Repairers and restorers did what they thought would work and did what the had to do to get things back working.

I can see no other use for that washer but as always, I could be wrong.

Thank you Stan, Sounds like a very good reason to me. I will have to pull the housing out that I got with these and see what is up with it and if these parts came out of it.

I did a look over on the Hall-Scott housing I got with these parts. I don't see anything amiss to say the notch plate I was asking about even went with it. So it will remain unknown. Up there with the 3 steel thrust plates welded together that was posted as to why . Only they knew and they aren't around to tell us. Thanks again.
