From the position of the arm I would say you have over sized shoes in, but that is not a bad thing, I like the over sized because it gives a little more to work with when fitting the shoe. Or you have very little shoe left and the arm was installed 90% out.

Fitting the shoe, rub chalk, blue, or liquid shoe polish on the shoe lightly apply the brake and spin the wheel. Remove the brakes and sand down the areas that the marker has rubbed off, repeat, repeat again and repeat again until you have an even rub on both shoes all the way around. You will be shocked at how much brake you end up with.

As for checking the round simply take a piece of baling or tie wire clamp it to the swing arm with vise grips, bend it so the end is just touching the inside of the brake drum (you have to remove and use a spacer for the back plate) spin the wheel slowly and if the end of the wire shows even all the way around you are good (adjust the wire by bending it slightly in the middle) You can also use it to check the sprocket as well.

Not as accurate as a dial indicator but a whole lot cheaper.

I think DD had a thread about centering the drum somewhere on here a few years back.

I would take a look at the backing plate for signs of rubbing. unless the drum is rusty, the shoes usually do not make a scraping sound, the wheel just gets tight in spots. I have seen this before when the wheel wasn't spaced right. also look at how the plate is in relation to the swing arm.

Is the FSM term for the "backing plate" the brake side plate?

I have dealt with this problem - spacers were not correct.

Got the rear wheel and rear brake off and immediately noticed that the pads weren't beveled (thanks Junior!), not sure how big of an issue it is but could be part of it. Any recommendations on how to bevel these? I have a bench grinder but imagine there a better ideas than that...

The pads are .19--is that stock? Couldn't find that info in the FSM or the parts catalog, is it in either manual anywhere?

Pads look smooth and have a fairly consistent .19 throughout, but do have some "imbedded particles" but nothing major so I think they'll stay:



Not sure how severe this is but it looks like there is wear on the cam shaft (not on the shaft bearing surface, right?):







I still need to check the roundness of the drum, and will check/post pics of the backing plate and measure the spacers tomorrow.

The linings are stock thickness and new.

Take some pictures inside the drum and around the back plate edges on the inside.

Was that cam seated all the way in? (doesn't look like it)

You can bevel the lining with a heavy cut file or if you are very careful on the grinder I like the file myself, takes more time but makes a much nicer looking job.

Also check and make sure the third bearing is still in the wheel.

It is a lot easier if you take good pictures of everything that could be an issue and post them all at once instead of piece mealing things one at a time, that way we aren't left to guessing.

Looks like it is the washer on the end of the cam is what has been causing the noise. It is supposed to be a thin, flat spring steel washer, and it is not supposed to be worn down like that.

If it is a regular washer rather than spring steel it will not work, needs to be replaced with the correct part.

Mick--I looked at 44264-54 on ebay and I have the same flat spring steel washer, but mine has a lot more wear and is not round. Given that it's the same flat spring steel washer, think I should replace it?

simeli--I'll take pics of the backing plate and drum, and check the bearings

If it is the actual spring washer, just worn, it should be OK. They are a PITA to replace. Easier to buy a complete replacement cam. Might look further into why it is worn so much. If it is the part causing the noise something needs to be fixed or adjusted.
