Topic: Rear rim removal on 1971 CB750K1 Swingarm

[Yamahawk]

Now, I have been working on bikes for years, and have ran across some rims that are easy to remove, and some that take a bit more work. My Royal Enfield is pretty easy, with the sprocket staying on the swing arm, and the chain also.
I was reading up on removal of my rim on the CB750K1 I have, and both manuals say to just loosen the nut on the axle, but do not say to remove the axle, but to loosen the chain adjusters, and swing them down, and remove the rear wheel. This is after disconnecting the brake stay and rod. Is it possible to remove the rear wheel without pulling out the axle first, or the chain? I imagine that the axle would have to be removed eventually for brake shoe replacement, or tire replacement, but was curious as to the easiest way to get the rim off the swing arm? I was prepared to disconnect the stay, brake rod, remove the castle nut and cotter pin from axle, then withdraw the axle from the rear rim, and extract the rim from under the rear fender, after breaking the chain at the master link. Would this be the proper way to do this? Or, is there a more efficient way that I am not seeing...

  You can leave the chain intact by going forward, slipping it off the sprocket then go back off the swingarm, under it and slip the chain off the side. I usually pull the axle since it's almost always coming off anyway. Keep track of the spacers.

 The reason the book says to do it that way was because when the bike had the four original exhaust pipes it was not possible to pull the axle out the side because they were in the way,hence the ability to slide the rear wheel out the back with it (axle) in place. On 750's I am working on that do not have original pipes I just drive out the axle and do it that way.

Aha! Makes sense. Those pipes were nice, but looked like they were in the way, at least Honda devised a way to remove the wheel without removing one or more of the pipes. Thanks!

My K6 has a riveted chain.
Rear wheel too front position for max chain slack. I lift the front sprocket with chain on, move it backwards. The rear sprocket will then get chain slack enough to lift the chain off. Since my bike has 4-4 the axle cannot be removed without wheel taken out first.
Brake rod and  bracket to brake cover to be removed wich take a minute.

Chain guard to be lifted too.
Riveted chain adds a lot of extra work!    Chain with clip much easier to handle when rear wheel has to be taken out.
Cut the chain and rivet again? NO thanks!!

Unless your chain is endless it's easier to remove the master link than to keep the chain intact. Have to take off more parts to get the chain off intact. I just had the wheel off my 400 and the axle just barely cleared the muffler (the head of the axle is on the muffler side and it slides out with millimeters to spare).

Yeah, I just ignored the manual and took it off like I have all the other bikes I own lol... Got it sitting in the back yard, and am going to take it to the shop as soon as they open! Hopefully Pat has some brake shoes handy that will fit it. and I will replace them also!
