I finally got both pistons out of the rear brake caliper.....It took the pneumatic powered grease gun and a lot of coaxing. Took a while to get all the grease out. Now, I have realized that my master cylinder (rear) is in disrepair. I'm going to have to rebuild it. Looking for those o-rings that go inside the caliper for the pistons. There were 2 for each piston; a small one and a larger one.
I always got my 1100 brake rebuild O-rings and such from partsnmore.com.

Okay. I replaced the water pump, front engine cover gaskets, fuel tank, sending unit, radiator hoses, battery, dog bone fuse, and some other things that I can't remember at the moment. So I filled it with oil and antifreeze and fired her up. Everything wss running like a dream. I shut it off to adjust the idle and noticed a hole in the RR case (I'm guessing that this is the transfer case??) and a bolt was sticking out with a washer jammed in the hole. Obviously this had nothing to do with the engine so I'm assuming it is the transmission or clutch. I gave up at that point and decided to cut my losses and just purchase one that is "ride ready", but after having 24 hours to mope around, I decided that maybe this is just another part that I can replace. So, what do you guys think? The fact that it used to belong to my late father is the only reason why I've been trudging along with the repairs needed from it sitting for so long. Should I continue or is this something that isn't worth repairing/ replacing? I've posted pics of the part. Thanks again!

That's the bolt that holds the rotor for the alternator in place on the shaft. Thread the bolt back in there and torque it down (don't have the torque spec handy). You may want to shift transmission into 5th and have someone hold the rear brake to apply the torque, otherwise you'll just be turning the engine....

There's a threaded cap that screws into the hole. I think it's the same cap as goes in the final drive for oil fill. Looks like your cap is missing... Still available as of a couple yrs ago.

Mine did this too....

Ahh. But what the picture didn't show was the threads inside the cover for the cap. I'm almost certain that they are pretty messed up. I found a replacement cover on Ebay for $35. Very clean. What do you suggest? Found the torque specs in the service manual - 62 ft lb

I think you might find the threads in the cover are OK after you pick out all the remnants of the threads from the cap that are stuck in them. I can see in your picture a chunk of that getting ready to fall out. A sharp enough pick to dig the detritus out of the threads and you may find you don't have to replace the cover.....

Of course, if you can't clean out the threads, the new cover isn't that bad a price :)

You might want to pay extra attention to your charging voltage, when the bolt backed out on my rotor, it allowed the spinning rotor to slide into the stator and ground down some of the windings, ruining the stator. with any luck, your rotor hasn't done that, and just tightening the bolt you will be ok.

After you put the bolt back in, start the engine and measure charging voltage, if it isn't up to snuff there's other tests you can confirm the rotor with. But be prepared, you may need to order a stator, too.

10-4. Thanks for the advice. And, from what you have said, I won't be cranking the engine until that is resolved. Thank you very much. It's good to have fellow wingers that can help out with these (strange to me) issues.

***UPDATE*** I just cleaned the threads, put the bolt back through the washer and when it gets to about 16 ft-lbs of torque, it breaks free. Thinking that the threads are busted. Hoping that is not part of the block, but that's what it looks like. Worse case scenario, I can check the bolt after every time I ride it or try to find a replacement block. What do you suggest? I have a new cap coming in Monday. Only paid $6 on Ebay for it.

Thanks again,
Randy

Well in the pic of the bolt you put up that thing on the right looks like the remnant of the old cap, if thats what you are refering to as a washer leave it out of the equation for now. Looks like it was overtightened and the centre broke off, I've had that happen before, they are just cast aluminium and dont hold up well to over torquing.

As for the breaking free are you sure it's not just the engune thats turning?

That's a good question. It makes sense after browsing through the service manual, it continues to show the T-1 mark in the inspection cap for the timing. I figured that if it was turning, I would have heard some noises indicating that the engine was turning but I don't recall hearing anything like that. Does that mean that I will have to remove the timing belt cover to lock the engine in place or can I just put tee transmission in gear to keep it from turning?

Put the engine in 5th gear and have some one hold the brake down.

Roger that. Only problem with that is that the brakes have been removed, but 5th gear may be doable.

***UPDATE*** For everyone else interested in the project so far, this is a link to my YouTube upload of the bike cranking before I replaced the water pump. Not bad for half pipes, rebuilt carbs, plus sitting for almost 18 years.

You could probably put a bar or a broom handle thru the rear wheel resting against the swingarms. Rear wheel won't turn then.

i love a good resurrection !
i don't see where anyone has mentioned it, but i have read that certainly harley davidson mufflers can be fairly easily adapted for use on these bikes. they are all over craigslist for cheap because the harley guys take them off when new.
keep up the good work.

Thanks for the support. Btw, the is no rear wheel on the bike so that is not currently an option.

Another trick to holding the engine crankshaft while tightening some other bolt....
Pull spark plugs. Push a few inches of rope down one plug hole. Slowly start the tightening process as piston comes up to "compress" rope. Finish tightening, slowly back crank a short way in reverse and remove the rope.
We use this technique on jet skis which don't have brakes or gear boxes... to remove flywheels or couplers.

Well, I got 12 tubes of Permatex Red 271 (I think) which has a 500⁰ temp resistance and is a permanent bond. It should hold for what I need. I'll keep an eye on it after I start riding it. Why did I get 12 tubes, you ask? They were marked down to $.05 @ Advance Auto Parts and he couldn't sell anything marked that low so he just gave them to me. They were discontinued and it would make they're sales numbers look bad or something to that sort, so I took all of them. Anybody need a tube?

Next step, while I build up capital for the next steps, I need to find some used or new brake calipers, front and rear, along with the front brake reservoir and rear brake master cylinder. I'd rather just replace them than rebuild them. I've searched the web and Ebay and have only found the front right caliper on Ebay.

Thank you.

Even if you find them on e-bay you would likely have to rebuild them too.

You're right. Good news though, I was able to fix the front calipers. They were stuck. I also cranked it again today. No issues except that it must be cold natured. It's in the 40's here in Alabama. But, for some reason, the rear brake lever is not springing back. The spring appears to be connected properly. Any suggestions?

Thank you.

Probably rust in the pedal pivot. You'll probably have to take the pedal off and clean/lube it.

A very common problem. Take the rear pedal off, wire brush the corrosion off the pivot pin and the inside of the brake lever, pack it up with lots of grease, and it should be good for another 20 years.
