painting a prop shaft
blakep82 - 25/1/10 at 05:36 PM

this might sound silly, but i remember reading something like this before somewhere...

i'm going to want to paint my prop shaft. the paint finish isn't great from the factory, and some has scraped off already. its not been run on the car yet, so don't really want to get into taking it all apart and risk breaking it, so...

... can i just hang it from my garage roof and spray it? or should i mask up all the bearings and greasing points? i obviously don't want to ruin it lol

Mask bearings. They should be sealed but, paint solvents can be quite thin.. Used a paint brush on mine, problem solved..

I'd masking tape the any nipples before spraying.

This might sound dafter, but make sure you get an even coat all over, more paint on one side can throw them out of balance!!!!!.

yeah, something else i was concerned about. the prop is quite long too.

is it possible to brush paint with paint intended for spraying? its going to go the same colour as my axle, gearbox, and bell housing, and a few other bits, so was wanting to get everything all ready to do at the same time. but all the bearing and stuff just worry me a little.

..... and after painting it, check for any insects stuck in the paint, heaven forbid a ladybird throwing it out of balance!!

I suggest you get it to lay on a sofa with one of it's UJs bent in a suggestive manner. You put on a smock and a big floppy beret, come in, set up your easel and say 'ze light iz perfect', paint away.
Surprised you hadn't thought of this yourself.

awesome

so, if i make sure the nipples (he he) are taped up, i guess i can spray the rest, any paint on joints will just break up i suppose but obviously try and avoid it as much as possible, and i can then re grease them just in case anything got in?

You probably should mask the bearing seals (to stop the thin paint getting past them). It might not be required but I would not want to risk getting paint in the grease.

You re-grease them using the grease nipple... Once rubbish is in the bearings you would need to take all the UJs apart and clean and re-assemble with new grease...

I used to build props for a living ........

The only parts we used to mask were the gearbox slip yokes (the part that slides into the gearbox). We didnt get paint on the flange surface becasue we sprayed away from it.

I would not worry about the Uj`s, seals etc. Just wipe the paint off the nipple before greasing.

If you wanted to be absolutly correct you should mask the flange where the bolt heads sit. It is bad practice to have paint between clamped surfaces and that includes under washers or bolt heads.

Cool, simplified that then I suppose the only problem might be if you have a modified prop the seals may-not be great (I know mine are a little split something for me to keep checking).

awesome top man!
so, mask the yoke, maybe blace a bolt and washer in the flange, mask the grease nipple (just because) and spray?

seems faily easy. thanks hopefully get a go at it later this week or next week
