Mornin all!

Anyone know anyone who can do repairs on alloy rims with minor rim scrapes such as those created when becoming intimate with concrete gutters? And If so, do you know what they charge?

I recently bought an R33 GTR and the wheels it had in the showroom were nasty 3 spoke uglies. I asked them to replace them with the original GTR rims but the only ones they could get were slightly scraped.

Any help would be appreciated as these little things are as annoying as flies up your nose! Well that's just me.

Thanks

O.K, I've repaired gutter rash before on rims....I get really cheap rims by buying them all scratched up!

Depending on how deep your scratches are, this process will work. I have used it on scratches up to 2mm deep. Anything deeper, and you'll probably need to have material welded in so you can rework it.

Remove tyres from rims(makes things a LOT easier).

Start sanding with a sanding block and very coarse wet/dry paper, I usually start with 60/80 grit. Work the paper so you follow the rim around, be patient, the early stages with the very coarse paper are when you remove lots of metal. You'll go from 60 grit to 180, then 240, then 600 then 1200.

Keep going to a finer paper(I like to do all the rims with one grade, switch grades, go over them again etc, just so you don't get confused)

You'll need a half sheet of paper of each grade per wheel, maybe a whole sheet of the coarser papers if your wheels are a bit mangled.

When you get to the 1200 paper, you have the choice of leaving it in the 1200 paper look, which is a nice brished look, or polishing. I use that polish in the pink tube, forget the name at the moment.

Allow 2 hours per rim and you should get close.

You may want to consider stripping the old paint before you start this if you have any old paint on your rims, any god stripper that's safe on aluminium will work, paint comes off aluminium easily.

Regards, Andrew.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
