Powdercoating pulleys
 

Wondering if anyone has done this or if you know anyone with it done. Getting close to having motors running and wondering if anyone has blasted and powdercoated their pulleys. How does it hold up? This is for v belts if that matters. Will it affect the belt? Thanks for any help.

I've powder coated just about everything that can fit in an oven except for pulleys. Not that I wouldn't but just easier to throw a coat of paint on when the engines are out. I don't see where it would hurt in the groove but if the powder coat does start to chip in the groove where will it end. Can also use heat tape in the groove I suppose. Rattle can some merc blue on them and be done with it. Just my advice. During the marinizing with removal reinstall etc there are parts that tend to hit the floor at times. Im careful as it is but it comes to a point where enough is enough.

powdercoating is good stuff, 3/8" rope in the grove, masking tape, tube of cheap silicone and a cauk gun I would cover the v with something, belts are cheap.

Sorry I didn't directly answer your question but just throwing an opinion out there. I'm rather particular and like to keep things neat, clean and even a little over and above pimp but there's just so much you don't see or notice once all said and done.

getrdunn you can remove what I suggested before it goes to the heat cant you? I have only seen powder coating on a assembly line, I might be all wet here, and don't want to give bad advice.

Tape the grooves. Id prefer paint.

Just curious why?

Great answers guys. Keep em coming. All of my accessory brackets are being done in silver. Painting motors, heads, intakes blue. Valve covers to be blue with silver logos. Was thinking of pulleys being done in same silver. Just to give an idea of what I'm thinking here

Surpentine belt pulleys it does not work on. It tightens up all the tolerances to much and the belts don't fit unless you tape off all the surfaces perfectly even the inside of the taper. I Found it much better to tape off and paint the faces.

You ought to buy an inexpensive gun and just do yourself. Just find an old oven for your garage or shop. It's extremely easy. In regards t othe groove they make different widths of heat tape that can withstand the heat. 3/4" I think even came with my kit. Only thing is with poweder coat is you need to be extremely careful from where you coat to the oven. Anotherwords don't sneeze on your parts. Lol.. honestly I don't think it would be a big deal if you coated the goove especially if you didn't consentrate on it. Just both sides and a little mist in the groove shouldn't hurt anything. Ck on eBay. If I remember the kits are under 100.00 and when you get merc blue and silver you'll be powder coating everything. Keeps you out of trouble also. Hah

If I lived in cape coral, FL had a 35' Fountain I would throw the rattle can in the trash and never look back, but I don't yep I use the rattle can.

I just black anodized a brand new pair of polished aluminum serpentine pulleys for my Hardin 3 stage water pumps. All so they would match the OEM black on crank and other accessories. Turned out nice, and no need to worry about paint or coating pealing off. But that only works on aluminum.

I don't see why powder wouldn't work. However for the time and cost involved, probably just sand and paint them and still look as good.

The powdercoating I plan to sub out. A few shops around me that do it. I have to finish and paint motors. Trying to get this thing back in the water asap. I have a whole bin of parts. Some of it to be blasted and coated. Some just blasted. Just thinking of tossing he pulleys in the bin. Lol

Very inquisitive abought the anodizing and the powder coat as far as color matching? I do automotive paint. anodizing is soaking in a some sort of bath with electrolisis am I right? can I 5 gallon pail a few small parts and if I can what would I be left with in waste. my gut tells me the powder coat would be more easy to match. New era fellas I see the epa getting castrated.

i.c.u.loking sorry I look back in my wake and see I may have highjacked your post not my intention.

It seems like the v belts would just ride a smidge higher in the groove is all as long as the powdercoat stays intact.

Power coating serp pulleys is no big deal, Ive done it on several engines with no issues, Im now doing my own.

Mine are vbelt. But that looks great man. Nice job.

Ken, where are you getting them powder coated locally? Looks good

Industrial coatings did those, but Im doing my own now, heres a ps reservoir I did.

They look a lot better in person, their a candy blue but it doesnt show up that way in the pics

Wanna do a few more. Lol. Looks good

I powder coated pulleys for my 540s a few boats ago. No problems. I did them at home with my own powder coated and shop oven. Held up, no problems. Silver

Sure, thats why I bought the equipment, I've got some black chrome powder that Im anxious to try

Black chrome???
Interesting

When do you plan on doing it? Would like to see some pics. I have a lot of hardware that is bright anodized. As I understand it the metal is polished prior to anodizing. It has a very smooth polished appearance and I was considering trying it on the pulleys. I'd like to see if your black chrome powder is similar.

Waiting on my media blaster to show up, I should get it baked in about a week or so

I'll start pulling pulleys:drink:

Alright...I see some new toys coming to my garage. Does this just ruin the oven and need one dedicated, or can it be thrown in with the wife's pot roast on Sundays?

Let me know how that one works out for ya.... :eating:

I bought one from craigslist and have a dedicated oven. Easy to find old takeouts that the oven still works

Here is some from Brembofreak

Can you powdercoat over powdercoating, or does it need to be blasted off?

My blank metal before coating! some of my engine are made fraom alloy,as new Motor ! I would do alltime again.
My meaning first was that coating go away on area where the pulley belt work. But it is there like new.No signs of wear.
Very hard coating! Michael

If you have the correct equipment you can, it has to be done at a higher amperage, the PS reservoir picture that I posted is a chrome base color with a candy blue over the top.

I powder-coated my serpentine belt pulleys several years go- 0 problems and the pully surfaces are unblemished.

Michael,
Is that a 496 in your Baja? It looks nice with the powder coating! Was the alternator spray painted, and was it did-assembled first? Thanks

No, is no 496!
One Generation after with many alloy parts like pulleys but also aloy heads.
The Generator was spray painted one year later.But i have an aftermarket here that i want take in parts and also coating.
Also want to powder the heat exchanger too.

So it's the 8.2 HO 502 correct?
