Teds new project a CB500 K1 mostly version 0.5 circa 1972.

[McCabe-Thiele (Ted)]

Isn't that because the heated it a little too much? My powder coating guy re-did  my Guzzi wheels (which looked fine to me!) without me even asking. He said that the pimples / spots were because the oven temp was a little high.

My hubs are okay - if it bugs me in the furure I can have the brake plate  re-done next winter - the Guy at CWC was a  Brummy with the famous patter so I accepted his reasoning that it was old alluminium causing the gassing problem. I had done some preparation on the brake plate beforehand as well.

Despite the warmer weather I am leaving fitting the wheel bearigs until I've done some other household tasks plus some garden work. I plan to ride the 400 as soon as the weather really warms up for me - I can finish  the 500 build if we have a wet summer.  My original plan to have the 500 done for my Birthday in early May 2024 has been put back a month or two.

Never say never -  atm the 500 is my last full project - I've gone off the Maicoletta idea for now as there is a very small pool to choose from with all the attendant parts finding problems. Might all change when I go to Stafford Bike Show as the Maico Owners Club will be there.

I haven't the room for 3 bikes and despite it being too small for me I like the 400 more each time I ride her so I can't bear the thought of it having to go to make room for a  Scooter.

Another shed Ted!😜 (and it rythmes)

My opinion for what it’s worth Ted. Don’t sell your 400 Ted after all that time , effort, blood sweat and tears. Only you know and can fully appreciate how much has gone into it. Going slow and tinkering away with the 500 will keep you garage busy this summer. Wthrres no rush if you’ve got a bike to ride and enjoy. When both are finished would be a good time to think about another project, if any. 👍

You speak the truth David - my first project is like my first GSDog only death parted us after 14 years. 

PS Not to mention the Money Pit balance!

Not  worthy of any photos as it's a pretty mundane task needing a bit of energy with a medium sized lump hammer.
So this morning fitted the front wheel bearings in my 500 hubs.

As well as the bearings being kept in the freezer for a couple of days I warmed up the hubs a tad with one of Wendy's old Hairdriers on full heat as I did not want to risk anything hotter.
I had checked that the new retainer fitted the threaded section beforehand.
After fitting the bearing the new retainer did not want to go in by hand - I started to panic.
I saw that there was a slight bit of thread near one of the four original stake marks that was slightly flattened - probably caught the edge with my drift tool.
I used the old retainer as a sort of thread cleaner after loading it with grease. (I cut four slots across the width of the thread, wire brush and remove any burrs.)
New retainer then went in by hand after clearing out any debris in the grease.

I have a small piece of plastic speed fit pipe with a slot along it's length that I use to hold the retainer in position when fitting the second bearing. It might have been my imagination but the bearings  seemed to knock in a tad easier with the added heat on the hub.

I could not find a torque setting so settled for very tight plus a bit of extra on two opposing slots with a small screwdriver blade.

Sounds like good work done there Ted! Satisfying end to a small crisis.👍

[McCabe-Thiele (Ted)]

It was a sheer panic moment at first Johnny - front wheel is now fitted with caliper in place just leaves torquing up the front of the axle clamps, then the rear.wheel bearing to fit.

Currently starting work on the rear hubs.👍👍👍

[davidcumbria]

That’s a proper old mechanic trick for cleaning up the thread. Satisfying to get the nest bearings in 👍

[McCabe-Thiele (Ted)]

It's something my late father taught me when I was in my early teens David and have never forgotten.
Not done it for several decades though as I pretty much stopped servicing my own cars twenty years ago.

For the range of smaller Honda threads I have a few taps & dies.

Question

Do the rear hub cushion rubbers need to be fitted completely dry ?
I was thinking a light smear of rubber grease might help with fittinng the outer drive part.

[McCabe-Thiele (Ted)]

I have fitted the left rear fixed bearing in place together with the short & long spacer & retainer ring nipped up. Spacers all held in place with a piece of slotted plastic overflow pipe to maintain alignment.
My next task is to fit the right rear wheel bearing - my concern is to avoid any chance of thread damage to the bearing retainer threads whilst fitting the other bearing.

I was going to leave the retainer screw off, then fit the bearing but want to avoid any chance of damaging the hub thread as I use a wooden support at the centre with a rubber pad on top.

Would it be okay to fit the retainer ring first and just support that instead?

Is there a best way round to do it?

I plead guilty to over thinking in advance!

Never had a problem just knocking them in Ted

Never had a problem just knocking them in Ted

thinking it through Bryan  it will make no differance if the sprocket carrier is in place or just the steel retianer ring - same force on the same part when knocking the bearing in - I'll make sure I've warmed the housing up first.
