Thread: Powdercoating a GEN V help

GEN V with 33K miles is getting powdercoated.

How do you completely take it apart?
What needs to be replaced after taking it apart?
How do you put it back together?

I spoke with Farnsworth about getting my Gen v powdercoated. The snout needs to be completely torn apart and you definately need new seals and probably should replace bearings but don't have to. He said he doesn't yet have a tool to remove the needle bearings on the Gen V so good masking would be in order. I also don't think putting the rotor pack through the powdercoating would be worth it for the little strip of exposed metal(polish it maybe). I don't know what to do with the actuall blade of the bbv but just make sure masking is emaculate. Ultimately i decided to paint it instead





I'm going for a two tone can't wait to remove the masking.

Are the case needle bearings differen in the Gen V from the Gen III?

If they aren't, Ive got a tool to remove them. I can take pics of it because they are easily made.

^ I asked Farnsworth about prepping for powdercoat because i knew he routinely took the blowers apart for polishing. He said something to the effect of he didn't have a tool or didn't know how to remove the needle bearings from the GenV yet.

Well I'll work from the assumption that the Gen III and Gen V use the same needle bearings. I cant see any reason they would use different set ups. And in that case I have a tool that will remove the bearings. In fact I used it on my spare case to pull the bearings out to replace them.

Can you post a link to the needed tool?

There isnt a link actually, but I can post up some pics. Its a simple tool.

If this is what you REALLY want to do, here is some help for you.

If you powder coat a M90 the snout will have to be gutted, not bearings or the seal should be in it when its done. Prime example of one that was not gutted when it was sandblasted, and then powder coated:

The rotor assembly...not a good idea to send that through an oven, unless you fully disassemble it to remove the seals behind the rotor gears. You can do it...but you will regret it later down the road. Again...trust me on this.

The case, you will want to fully gut it as much as you can. The BBV butterfly flapper, there are two screws that hold the butter fly to the shaft, take the screws out, and then the flapper will pull out, and then the shaft slides out. You will want to take special care to seal off the exposed needle bearings that ride on the shaft, you do not want sand or powder getting in or on them. These are not fun to replace.

As for the needle bearings, they are the same as whats used on a genIII M90. problem being is a GenV does not give you "ports" to tap, and insert your threaded grease pressure remover tool to pop them out.

This is what the tool looks like:





Flip over a GenV there will be no holes in the case. I have designed a tool that will remove the case needle bearings from a GenV. It will pull them out instead of push them out. I just need to make it.

For the mean time, if they are not bad, seal them off good using high quality tape that will tolerate the heat from the oven. The special tape I use on my parts before they are powder coated will withstand temperatures up to 500*F.

I have never had to send in a complete M90 to be powder coated. I have done many snouts, and then I have also removed powder coating from blowers to polish them, and then a whole bunch of painted ones too for those who have changed their minds later down the road.

Farnsworth, thank you for clearing that all up. I did not know the Gen V did not have the holes on the bottom and as you pointed out, without those the tool is useless.

I am curious about that tap set you used in your ClubGP post. Where do you get one that works with a ratchet?

F,
Lets just say I don't trust myself doing it, do you have the ability to to it if I send it to you? I know you specialize in polishing, but can you have things PCed as well? I trust you more than anyone on here to dis-assemble these.

I bought it from ToolParadise.com - It's Paradise for Tools! Professional Tools for the Mechanic and Serious Hobbyist

I think its this one:
ToolParadise Database
but the one I have is in a blue plastic case.

Comes with a lot, but bought a few extra pieces that I needed for a few special jobs here and there. Worth its weight in gold for me, and how much I use it.

Powder coating, thats where I got my start helping people out. It can be done yes, if you really want it done. Colors...name a color, or if you have a for sure particular color you want it done in, send a swatch sample ahead in the mail, and let me do my best to match it to what all 200 colors they have in stock. Then, we'll go from there if you like.

I'll see about getting you a quote once the colors been decided. Cheaper colors they run all the time is flat, satin, and gloss black, few reds, and whites, and silvers. Other colors are called "specialty colors". Meaning its not a normally run color, and they have to stop the line, and reload the gun for that one color. They do all of Big Dog's motorcycle frames Big Dog Motorcycles - About Us for them as a big time customer name drop of theirs.

Just a simple bright white.

That would be easy enough to manage I'd say.

I'll do some checking for you on a price and get back with you.

Great, thanks for your help. And you are confident you can take it apart and put it back together correctly?

For your GenV or any other M90, I am not going to even mess with the rotor assembly. Too many people picky about their rotors to have a problem come up, and fingers get pointed. I will not even do that part of a M90 for powder coating regardless of how much you pay me.

If you want to do the snout, and the case, I can do those no problem, and stand behind my work 100% no questions asked.

I can handle it, and am pretty confident of what I do with everything else. Been doing M90s for quite a few years.

So before I send it you would want me to seperate the 2 halves and remove teh rotors? No problem there, I think I can handle that part. It is housing and snout, and probably some other misc parts just so the PC matches, brackets and such.

Yes, you can separate the rotor assembly from the snout and case, and just keep that. It will also save weight in shipping, as thats the heaviest part of the blower.

Do you, or somebody you know own a torque wrench? You will want to use one when you put everything back together, and of course reinstall it onto the engine. Just a heads up.

What other brackets, and misc parts do you have in mind? Give a list, or take a picture of it all.

Know what looks bad ass on white IMO, chrome. The bolts to the blower and other hard wear near or on the other things you are thinking about having done in white, getting the hard wear chrome plated would look so hella bad ass.

Just throwing that out there in case your interested.

Farnsworth, am I to understand correctly that the rotors themselves could be powder coated?

Parts:
Snout
Housing
TB adapter
T-Stat housing
Coil bracket dogbone mount
Opposite side dogbone mount

oh....and the color scheme isn't going to be white and chrome, but I do agree that would look sweet!
