Silver Engine Powder Coat Problem

[TxRIIIRider]

Good info, Eric..
Next time I'm in Austin, I will have them take a look at it. I plan on taking it up there this Winter some time to have the valve shims checked and make sure my cam chain tensioner is holding up.
My local dealer wouldn't have a clue..

I think they just look better black.

I actually prefer the silver engine!
The paint on my Silver engine still looks good but the silver paint on the final drive is starting to bubble.
Does anyone know what paint and colour would be suitable?
If I removed it could the bearings stay inside if it had to be powdercoated in an oven?

I don't know what the color is.
If you removed the final drive, You probably would also need to remove the bearings if you intend powdercoating.
Powdercoat is sprayed electrostaticly, the powder goes everywhere, insides stc.
Also to get the powder to liquify and flow as well as cure dry, the object has to be baked at about 300 to 400 degrees fahrenheit (150 to 200 degree C.) I don't know if this is good for the bearings. Also with the expansion of the bearing recess, the bearings may move?

I am thinking that you could have the drive shaft housing sprayed with a eurethane enamel, does it get that hot in service?
A base coat with a clear coat may do the job. Maybe you could visit a automotive paint distributer and ask him to borrow some paint sample chips to take out to the parking lot.

cleaning

TxRIIIRider.

I am curious, your engine looks very clean.

Do you use a special cleaner to wash the grime and dirt off.
The reason for the question is: maybe the detergents in the cleaner are too alkali for the type of powdercoating that was used.

Thinking too much, that's all

Unfortunatly yes ... more like 'i've been down a very long road and ran most of the way'

I was told you only run when your being shot at

bingo...exactly what I was thinking...did someone shoot some carb clean on the block to remove grease/grime..possibly the aluminum wheel cleaner stuff with an acid base....

I think it's two problems.. on the left side I have used wheel cleaner to remove some grime... and on the exahust side, I think it's just the heat.

This is only one out of thousands of silver engines. I was just asking if anyone else had this issue. I could have a engine finished by some guy with a hangover on an early morning in July 2004 who didn't clean my engine properly before it was coated..

My 05 Silver Motor still look good I just give it a clean water pressure spay wash occassionally it comes up good..

Maybe that is what it is!

Wheel/brake cleaner is on the acid side and some strong detergents can be on the strong alkali side on the Ph scale (I am thinking of the stuff that is normally diluted with water, use it straight or not enough water blend and it can cause a similer problem to acid)
