'77 GL1000 Rear End Ticking

[Whiskerfish]

Can't beat the price of this rear end ...might even have GEM gears installed ~:<)

Wingnut Why would you think that?? I did not see any indication in the listing??

Ben, GEM gear sets are a different ratio gear set that was primarily developed for those that that put side cars on their Goldwings. Over the years they have become quite desirable due to their limited availability.

OK video detectives, I've got a new video for your listening pleasure. I took the bike for a long ride to get everything warmed up. Came home and held the phone to the rear end while I pushed the bike back and forth with the motor off. I'd swear it was wheel bearings if I hadn't just swapped them out.

Take a listen please.

I was going to reply earlier about the possibility of something inside the wheel itself. Another member here (I don't recall who) described a very similar sound. The rim of the wheel is actually extruded, formed into a circle and welded. There are cavities inside, and it is possible for a stray piece of metal to be captured inside...
You may also have something captured inside the inner rim/flange area. I'd pull the wheel and give it a spin by itself. My 2 cents...

Hope it's not this but on a friend's Valkyrie with a tick like that, I finally found it to be the bearing land was slightly out of round. That let the bearing "wiggle" ever so slightly as the wheel turned. The only way I found it was with a stethoscope while turning the wheel, then used an inside gauge to check for trueness(is that a word?) of the circumference of the land once the wheel was removed for the Nth time along with the bearing. A little backyard engineering got him back on the road while waiting for a replacement wheel. I cut a ribbon out of a beer can and placed it in the low area of the bearing opening, letting it extend above the land and it pressed into place with the bearing. He actually left it in there until his next tire change since it didn't seem to create a problem, not sure I'd have done that however.

had a bearing start to go bad and it did a tick, it was from the bearing race starting to move within the wheel

I pulled the wheel. There's definitely something rolling around in the wheel. That's one sound. I'll get that taken care of.

The worrisome sound is the ticking. Without the wheel, I could just barely hear it when turning the spines on the final drive unit. I pulled it, cleaned it and now I don't hear the ticking, but I do hear a little bearing noise from the first bearing aft of the shaft drive coupling. What bothers me more is the obvious damage to the preload retainer and some heat marks inside the spline shaft.

I've got a final drive coming from eBay next week. We'll see if that one is any better.

Might not be anything to worry on the heat discoloring on the inside of the spline drive. It is likely from the induction hardening of the spline teeth that does a shallow hardening of the surface of the teeth for wear and fatigue resistance. There is always some heat discoloring on the thin sleeve. We do the same thing at work for auto trans shaft s and clutch baskets.

[rcmatt007]

I wonder if you had an overheating bearing

[Ben Diss]

What do you think of the preload retainer and all the damage? Maybe some debris got in there and chewed it up?

[rcmatt007]

all depends on whether a NEW bearing fits snug

[Ben Diss]

I picked up a replacement from eBay. It sounds good, but I'm disappointed that it's not in better condition cosmetically. I decided to rebuild the brakes since I had everything apart so I won't know if it's fixed until my rear rotor comes back from resurfacing.

[Ben Diss]

Update: I had the tire pulled and wheel inspected. The noise is coming from some debris inside the channel that forms the rim. Nothing that can be done about it, but nothing that could cause a problem either. That item at least, is closed. As to the bearings, I'm waiting for a brake line to come--I rebuilt the rear brakes since everything was apart--and I'll get an answer on that as well.

At least it's the devil you know now. Better than the devil you don't! Debriss. Who'd a thought it'd be debriss. (emphasis on the 1st syllable as they do in jolly old England).

Would it be possible to drill a hole in the area and fill it with foam?

[Ben Diss]

Would it be possible to drill a hole in the area and fill it with foam?

Perhaps. I'd worry that drilling from the inside might leave an edge that could wear the tube.

Perhaps. I'd worry that drilling from the inside might leave an edge that could wear the tube.

The last time this was discussed, the thought was to drill in the area of the rim that is covered by the tire bead. I don't recall if the person ever did do anything about it.
