Title: Cleaning rear hub
Post by: paulbaker1954 on June 14, 2016, 06:28:30 AM
Anyone used any magic potions on rear hub. I want to clean mine up better but can't get in there cos of the spokes. I tried alloy wheel cleaner (Autoglym) but just wondered if anything else would do a better job

I've always had good results using Wonder Wheels.

an old toothbrush is always good for getting at difficult places and if you're feeling really fancy, an electric one.

Pretty sure that hub will be clear coated if its original. This yellows slightly with age. No point in polishing it before that is removed. It comes off literally in seconds with Methylene chloride based paint stripper. How do I know? I stripped 6 fork legs and 5 Honda hubs yesterday. Very difficult to polish whilst laced. Toothbrush and solvol etc. Mine were all bare hubs. The dry-state  US import ones are amazing once you remove the yellowed clear coat. UK ones are a totally different kettle of fish. I just bead blast UK ones with 0/50 glass beads and then polish the outsides. A guy in Hull says he will vapour blast all of the hub centre portions after I have dry bead blasted  I have ( about 12) for 50 quid, just need to convince myself that the vapour finish is worth the extra expense as the dry glass finish is pretty neat.

Good option!!!

Good advice Ash, as you say mine is pretty yellowed

When you say paint stripper would Nitromos do the job?

Also a bit wary of using such stuff around tyres etc, any advice

Nitromors is rubbish now. I used the stuff in the 5l tin but both will work fine. Just keep away from the tyre. Doesn't seem to attack zinc plating if you are quick.

Don't get me on about Nitromors - it used to be fantastic until the Eurocrats insisted the formula was changed.  Now, you might as well pee on it for all the good the over expensive 'new, improved' Nitromors does. As Ash says, you need a stripper with methylene chloride which was the active ingredient.  I've said this before but I'd like to bet that more folk have died with heart failure ranting about 'new improved' formulae than ever died from the so called nasty chemicals. 

I always dismantle wheels to polish hubs, it's just too tedious otherwise.  Measure all offsets and take plenty good pics of spoke pattern and build them back yourself with a simple home made jig.  Just remember there are inside and outside facing spokes.

Good advice Ian...thought Honda wheels had zero offset .. that's what I was told on HondaTwins.net site

Hi Ash,
Yes, all the Honda wheels I have done (so far) have no real measurable offset but the spokes have enough thread to allow the rim to be upto 5mm off to one side, so I always lay a straightedge across the hub and record the distance to the rim before dismantling.  That way, no matter what kind of wheel I'm doing, the result is always correct. Another thing I try to do is match up the valve hole with any 'witness marks' on the hub.

Must talk to you about a supplier for the DCM stripper - always awkward in Orkney
Regards,
Ian

I managed to knock down the lady selling it to 20 quid for 5l  at autojumble and £7 for the 1 litre stuff..(1 litre stuff is more of a gel and marginally better) If you want me to get you any next time I am there , no problem and I can tie up with you if your'e in Hull anytime or leave it with someone who's coming to visit you.

Many thanks for that Ash,
Not sure when I'll be down in Englandshire again but will certainly bear it in mind.  Everywhere seems to want some cast iron guarantee that it will only be used in industrial premises, so might have to be economical with the truth - you know, like politicians.

That looks like the stuff Paul .. typically £7 / litre & even £20 for 5l at autojumbles though (e.g. Newark) if you haggle. I stripped a 750K0 rear hub carrier this morning, lacquer came off literally in seconds !

I picked up a 1l can of the Final Systems stuff from The Bay for £12.49 delivered which seemed not unreasonable.
Looking at the tin it seems pretty evil stuff, so before using it can anyone offer advice on the best way of applying and removing it, particularly on fiddly stuff like around brackets.
Thanks in advance.

Use it outside and don't get any on your skin as it stings like hell. Guess it has formic acid in it, which is the stuff in ant bites plus methylene chloride (supposed to be banned for DIY use). OK but just avoid the  fumes. It will removed Honda hub lacquer in a matter of seconds . Brush it on thickly with an old paint brush, leave for a few minutes then wash off with hot water and cheapo washing up liquid using a stiff brush or thick gloves and a scouring pad. You could also use a pressure washer after brushing in some neat washing up liquid. Totally non-PC stuff but awesome at removing paint/lacquer. Don't forget that for yonks we were sold Nitromors original formula, which is essentially the same stuff  and I have never heard of anyone having long term health probs from using it. OK if you were using it all day long, that a different matter but not for odd occasions in bike resto. ENJOY  :D

Just noticed the place you bought it from is in Hull Chris !!

Thanks Ash, that's really useful, I will give it a go.

I hadn't noticed where it came from, I was more interested in the line a bit further up the page starting with a '£' sign!
