I believe that the original stanchions were only chromed on the area below the bottom yokes as the rest is covered by the headlamp brackets, mine stayed rusty!
Love the 500 and 550 have a 500 called Lazarus under restoration

Made this rusty bad boy after work today to try to remove rear hub bearing retainer. A quick clockwise tug did nothing but need to have a proper go tomorrow. Bolts are specials from a Kwak Z900 ...hows that for extravagance  ;D.

Read on the US site that you can hot tank the hub in the Ultrasonic cleaner to remove internal corrosion. Worth a try before I fk it up,

Wife was out   :)  If she's in Am Dram 'play' mode she'd probably not even notice it anyway. .... its sqeaky clean now anyway since I washed it in the parts washer then  bead blasted it.

Hmm .. The arrow to me means the tightening direction (CCW) for a LH thread so CW for unfastening .. or is too early in the morning. Not going to tug to hard on that retainer ... will heat the old US bath up and hot tank it for an hour or so.

BTW Found a great way of removing side reflector from the fork ear without damage ... push a CB750 K0->K6 carb inlet rubber onto it and unscrew that way. Loads of friction grip and zero damage to rare small reflectors (CB 250/350K2 part too I think)

I bought the tool from Silver's to remove my CB500 hub retainer last year. Incredibly tight all the way out, I had to have several attempts at it and yes, it was a left - hand thread (1974 UK model).

I know it's a left handed thread, the manual says so, however it doesn't make sense why Honda would do that as it loosens as the wheel spins, usually they'd have the tightening for security reasons if nothing else. Clockwise is the direction to undo a left handed thread so you were going the right way Ash, just threw me for a moment that.

Rotary inertia when braking?  Dunno?

Anyway Hot tanked it in a big Ultrasonic cleaner for three hours tonight as recommended by SOHC.net USA site ... still no joy. Soaked it in WD40.... again! Going to try lots of heat tomorrow but with care not to melt cush drive rubbers... difficult ! Also will drill stakes out a bit more just in case.

Had day off but worried I would fk it up if I didn't try US hot tanking firsts, so decided to investigate the cause of the non-operational kickstart on it's baby brother  it came to me with....the CB175K4... see new thread

I find that a good shock will sometimes start them off, once you have them going things go a lot easier. Try whacking the tool with a heavy hammer to see if you can shock the threads loose. Sometimes you need to do this in order to break the thread locks grip.

As far as I recall the rear retainer is not staked, unlike the front one.

Yea FBH I guess. Problem is, and it's my fault entirely, I stripped the wheel first not realizing what a b*st*rd these are to remove. Think I will weld a bar to the old sprocket to get a good purchase on it. Stripped the alloy retainers from about 12 Honda hubs, without the proper tool, over the past two years and never ruined one yet. But these are something else.

Yup, were always a barsteward to undo and all I ever had was a hammer and punch. Cant remember any stakings on the rear one. Talk to me if you damage it Ash as parcel is slowly being built up mate

Had another go tonight .. made a 5 foot long extension bar and heated the retainer as hot as I dare without damaging the cush drive , still no luck . Only thing I can think of now is it to locally heat the retainer by mig welding the top (high power mig at work) or just machine it out  and buy a new one. Getting pi@@ed of with it now .. it has to be the worst job by a mile  to do on any Honda I have ever owned.

How about cutting a slice out with a dremel.   The thickness oof the kerf should be enough to loosen it.  I shifted a bearing shell like that.
Where's that 10mm socket got to?

Yes ....not a bad idea  Mike.. Think I am just going to get a repro retainer from Silvers for 24 quid unless anyone on here has one to sell me.

Came home fed up after struggling in the freezing cold with the retainer on my own, so decided to do a few jobs that are totally within my comfort zone. Stripped switches, look fine. I have  reels of the correct sleeving for both sides   from way back. Will bead blast the housings and then paint and bake with PJ1 satin black, then light polish with Solvol.  I know renowned, top-notch restorers who use this method. Got spare parts as I just got repro Yamiya switches for my 750K0 and some parts are common but all contacts ect look fine and PVC wiring is still soft. Original black sleeving was toast.

Bars look OK and would look fine  if cleaned up but taking them tomorrow with kickstart etc.  to get the plating stripped, then I am going to polish and then get rechromed.

Repaired the one broken lug on one of the side panels... have to get it over to Menno Dek next week with the other side and the tank. Just love Candy Jade Green. Used the patent Ashimoto repair 2-pack adhesive mixture.

YES Pete it's the kitchen worktop again and she saw me doing it. She didn't moan .. just asked where her cuppa was !  After all these years I think she's given up and accepted it  :D

Mix this stuff below :- with 50/50 ground ceramic powder/aluminium powder until its the consistency of soft butter. Bond the two surfaces together with it (immerse the container in boiling water so the adhesive flows' ( it takes yonks to cure at room temperature) put the excess in a container in a sealed plastic bag in the freezer (don't tell the missus  :D) Once cured up ( about 24 hors)  take epoxy mix out of freezer and 'defrost' then build up behind the joint with the defrosted 'putty'. Wear disposable gloves !When hardened, fully post cure at about 65°C for about an hour until  it cures rock hard. Sand down to correct contour.  Trade secrets ... blah .. tell everyone, that's my motto.
