Powder Coating the Pork Chops....

[Richard Z]

I've been looking at some of the older and different models. I've noticed that some have the RED Pork Chops. I'm guessing that is the term....

 

Any guides for removing them? Suggestions? Jacking? etc.....

 

I have my own powder coating stuff and have been doing it for some time now....

 

Thanks,

They bolt to the rear end of the "spine" which is T'd to small discs that mate with bosses on the backside of the porkchop and are fastened with those 4 domed allen head bolts and nuts.

 

At the bottom they link the lower sub-frame.

 

Those large chromed nuts which appear to be jamb nuts (and are) fix the swingarm pivot shafts, which are threaded into the porkchops.

 

Pretty simple.........

 

Support the front wheel ( I use on of those drive-on wheel chocks).

 

Mount the bike on something under the engine to support the weight and unweight the suspension.

 

Stabilize the frame at the handle bars and upper subframe (remove the seat) to ceiling trusses if you can.

 

Remove the swingarm pivot shafts.

 

Remove the rear brake master cyl.

 

Remove all of the porkchop bolts/nuts and off it comes...

Thank you for the reply...... I have a motorcycle lift and an ATV/motorcycle jack. So, elevating and securing wont be a problem. I thought the removal looked straight forward. Just thought I would ask just in case there is anything hidden.

 

Thanks for the help.

One of the few places Guzzi gremlins are unlikely to be found.

 

Be careful with the lift......... the swing arm is going to fall out........

Make damn certain that the backsides of the porkchops are clean with no dirt or grit anywhere. If there is, you stand a chance on buggering the swingarm pin threads in the porkchop. BTDT, currently have one good and one bad black powder coated set of porkchops out in the shed.

Carl, can you explain that? How would contamination affect the swing arm pin threads?

 

Do you mean that contamination might lead to cross-threading when reassembling? or to some kind of wear as a result of pork chop to swing arm misalignment?

 

Assembling those pins into their threads was definitely a challenge!!

Thanks for the tip... After removal I was surprised by the corrosion that is already present. I am doing them one at a time so not to get my A$$ kicked going back together. While I'm at it. I'm coating the exhaust and anodizing some of the controls and brackets.

I polished my exhaust pipes.... resulted in a beautiful shiny gold color......

I used a silver coating that is about the same color as the cylinder heads. Almost has the same look as Jet Hot with a more satin finish. Took 2 hours to cure in the oven but turned out great. The PorkChops, well that another story. The Victory Red and Cardinal Red Powders are more orange than the paint. I found some darker red today and have to blast them again to recoat. What a PITA! (PITA=Pain in the A$$)

callison, was right... Its easy to booger up the threads on the porkchop.....

 

With some persistance I got it back together. I found a way of doing this without removing the the pivot bolts.... Do each side one at a time and don't touch the pivot bolt or jam nut. Just realign the pin when reinstalling. Use the outer monting bolts to realign the porkchops. I just masked off the bolt when coating and removed the tape before putting in the oven.

 

The threads on my left side are a little loose due to my error. So if there is an extra one someone has laying around, give me a shout.

That's powdercoat on the exhaust???

Yes, its a High temp coating from Eastwood. I used a conventional oven and a Craftsman powder coater. The first coating started to burn thru after a bit of riding. probably in my prep. So I sandblasted them again and roughed up the surface a bit with 3" medium grit scotch brite pad on a small dotco grinder. that give the powder something to bite into. Been about 1500 miles without any discoloration or peeling.

I've got check these posts more often...

 

Okay, I was adjusting my swingarm centering after having the pork chops powder-coated. Somehow, I got some grit or dirt between the swingarm and the porkchop on the pin. Centering the swingarm involves running the pins in and out full depth to take measurements and while I backed one of the pins out, the grit invaded the threads and started galling the aluminum threads badly. It ruined the porkchop. I can't even remove the aluminum that was bound into the pin threads. It was NOT cross-threaded, I had been running the pin in and out with no problem during the centering process until that tiny bit of contamination screwed up the whole process. Just make sure that everything is spotless around the pin on both sides of the porkchop when you're doing any adjusting.
