LR90 Posted May 22, 2006 Share Posted May 22, 2006 OK, good news is I've managed to get a disked braked axle to build up for the 90 and it came cheap Bad news is its pretty scabby so I'm looking for ideas on cleaning it up and getting some protection on it before it is built back up and fitted. Left to my own devices I think I'll be using elbow grease, wire brush and a couple of coatings of two pack epoxy. Are there any better suggestions? Don't think shotblast and galv would work as it would end up with galv in places I didn't want it. Used to be a container refurb place in Wigan that would do a great blast and isocyanide(?) spray that would have been ideal (though you had no say in the colour) but rather far away now. Anything similar in Hants? Anyway, ideas/suggestions/recommendations welcome. Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted May 22, 2006 Share Posted May 22, 2006 rather than elbow grease and a wire brush, I used a wire brush wheel for an angle grinder, and wear eye/breathing protection, because you'll probably end up red. it wasn't fun, but its fast.

Jon White Posted May 22, 2006 Share Posted May 22, 2006 Yep - wire brush in the angle grinder then a coat of chassis black. Dont use hammerite - its rubbish. Chassis black is great casue theres no need to prime it and it sticks like **** to a blanket! Jon Quote Link to comment Share on other sites More sharing options...
dollythelw Posted May 22, 2006 Share Posted May 22, 2006 Im a fan of shotblasting but unless you get a blaster that knows what to hit hard and what not to - and will mask all threads, seals etc that you dont want destroyed I would go with the grinder route - a cup brush and a flat brush can work wonders, a good degreasing before you start will make life easier as will putting the axle on trestles and securing it well, paint wise you can't beat 2 pack (IMHO) but a good, cheap and tough alternative is Bodyline chassis paint, thin it slightly and its goes on a treat, takes a day to reach a "soft" cure but within a couple of days you can beat the pooh out of it and it still comes back shiny Quote Link to comment Share on other sites More sharing options...
Daan Posted May 22, 2006 Share Posted May 22, 2006 I went the blasting route and then had it zinc plated. It looked good to begin with, but the after one winter, the zinc plating had gone very crappy and rusty. From everything I have done on my landy, the only thing which worked long time was galvanize. So I think that would be the way to go. Anyone here has experience with galvanizing axle cases? Daan Quote Link to comment Share on other sites More sharing options...
GBMUD Posted May 22, 2006 Share Posted May 22, 2006 You could go for a hot zinc spray - just as it sounds - that way only the bits you want coated get a coating leaving gasket surfaces, threads etc. alone. My feeling is that plenty of good quality paint will be ample. I back that up on mine with copious oil leaks. What about powder coat? That is well tough but will be damaged by dragging over rocks and stuff. Chris Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted May 22, 2006 Share Posted May 22, 2006 I always get my casings shotblasted. (i've got one ready to do actually.. that reminded me!), but shot blasting IMO is much better than wire brushing, which just seems to "polish" the rusty bits and smooth them out. at least with shot blasting the item comes back with a surface that the paint can stick to VERY well. costs about £20~ for an axle casing.

dollythelw Posted May 22, 2006 Share Posted May 22, 2006 Ive always found powder to be more brittle that two pack - I think Ripleys the man to ask which one is chemically stronger Quote Link to comment Share on other sites More sharing options...

Happyoldgit Posted May 22, 2006 Share Posted May 22, 2006 I would go the shotblasting route as well use someone who knows the biz. Quote Link to comment Share on other sites More sharing options...
simonb Posted May 22, 2006 Share Posted May 22, 2006 Just doing my series 3 axles. Wire brush attachment fitted to angle grinder will get them back to bare metal. Then rust proof using the Hammerite rust proofer from Halfords which neutralises any remaining rust. Its a white liquid which doesn't need to be washed off. Then I've sprayed with a rich zinc primer, Unidox zinc rich Primer from Witham Oil and Paint 01502 563434. It came out the number 1 for rust proofing in a car mag test years ago. Tin is mega heavy cos there is so much zinc in it. Gonna follow that off with a couple of coats of normal primer and then several coats of chassis black, the synthetic stuff - doesn't chip like hammerite. Thats if it ever stops raining Not enough room in the garage, so the axles are on stands under a tarp on the drive... Quote Link to comment Share on other sites More sharing options...
LR90 Posted May 22, 2006 Author Share Posted May 22, 2006 Wow, thanks for the input everyone. Sounds like I'll need to search out that grinders thread and replace my burnt out bosch unless I can turn up a local shot blasters. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted May 22, 2006 Share Posted May 22, 2006 If you're playing with the wire brush thingy, get two or three. They're not expensive, and they moult. As people said, hand and eye protection, and prepare to find little twists of wire in all your clothes (including underwear ) for weeks afterwards.
