Found source of Ruckstell noise

Post by Ruxstel24 » Wed Nov 20, 2019 6:57 pm

Went to get a last putt in couple weeks ago and was surprised with a snapping noise coming from the rear.
Got around to pulling it apart today with some help from my partner in crime. ;)
Everything went smoothly removing it and we made a support for the axle and got it mostly apart...most of one tooth MIA on the pinion gear and the ring gear is damaged too. :(
I have to get pictures of the inside yet, but there’s a weird looking shim on the left inner next to the locking plate. And what appears to be a thin snap ring ?

Can you post a picture of the strange parts? From what you have said, something must have been out of alignment between the gears.

Here ya go Norm. I think someone used this for shims ?
Joe Andulics and Tim Morsher are both kind enough to be sending me the manuals, Joe the Ruckstell and Tim the standard axle book. Thanks guys !! :D
One little chip on the ring gear, but not for me. I heard nothing odd, till I went to go out the other day....then snap snap snap, continually and I only went a couple hundred yards and back home. 13-39 gears ruined is a bummer.

Dave, if that chip is the worst of the ring gear, I would not be too quick to discard it. If you need a 13 tooth pinion, I have a nice one I removed from my speedster before I sold it. Maybe 5000km only. I kept the 39 tooth ring gear and used it with a 12 tooth pinion in my roadster. Let me know if you want it.

Thanks for the offer Allan !! :D
I am going to search my inventory for a 12 tooth and I will run that if I have one. If not I will probably take you up on your 13 tooth.
Hopefully today I can get it apart the rest of the way and clean everything up and get some better pictures. I will see if the crown gear has any other oopsies.

Looks like the spool for the pinion bearing is chipped on the edge and also I have not seen a lock ring like that on any Ruckstell I have worked on.
A problem with using two used gears which came from different axles is that each gear is worn to mesh with its mate and if you change one of them, you will have a different point of contact. This can cause at least three problems: Rapid wear until the gears mesh together, noisy gears, possible broken teeth because of very small area of contact which puts leverage on the tooth and cause it to snap.

I don't think the pinion housing is chipped, looks to be a lead gasket that has slipped. I think the shim and ring are spacers used because of wear in the case where the thrust bearing and notch plate fit. While a howling rear end might happen with mixing gears like the Model A, I have mixed gears in T rearends and not had noise issue. I don't think straight cut teeth is as much an issue in this case (so far in my limited experience). Personally I think people setup the rearend too tight for how it was designed so could be a factor in fast wear.
I know the voices aren't real but damn they have some good ideas! :shock:

Got the rest apart, nothing catastrophic found...
Everything looks pretty good, have to do some measurements to be sure, but most appears to be able to reuse.
I now understand how the outer bearings are setup. A sleeve is where the Hyatt was and a sealed bearing is in the hub.
Anyone recognize these ? I would like to get new bearings, maybe a local bearing supplier can match them up... ;)

More pictures...
The piece that looked like the spool was chipped was a bit of sealer, it’s on the floor now. ;)
Looked pretty hard today, no 12 tooth found.
Anyone have one, please let me know.

Dave, this is my 13 tooth pinion gear. It is barely polished and still shows machining marks on both sides of the teeth. Chaffin's 1916 catalog price was $175. I can let this one go for $150, including postage to your door. If you don't want it, others may chime in.

Thanks for the kind offer Allan !
I’m gonna hold out for a little while for a 12 tooth, but I may still take you up on that. :)
We aren’t having summer like you for a little while yet.

Anyone have an opinion on the gears Snyder’s sells ?

Is it possible that the snap ring came from the large bearing in the ruxtall? Next question is why would there be a bearing in the hub? If you were running the newer safety hubs that replace the Hyatt bearings in the housing I could see it but it appears you are not.

Dennis, those are an early version of the “modern safety hubs”. I was recently told.
No snap ring, so potentially you could lose a wheel if an axle snapped. But it’s still taking the weight off the axle and onto the housing. And no outer Hyatt bearing. I believe greatly lessening the chance of breaking an axle. Probably was set up in the late 60s or 70s.
It’s a large drum, so maybe it’s deceiving but it has sleeves where the Hyatt was.

I will inspect the large inner Ruckstell bearing closer, but it seems tight, smooth and intact. I haven’t started the clean up process.
