Cleaning Oxides from Motor

[pmilano1]

Greetings-

I have a GS540, and the motor is horribly oxidized. Is there a magic solution to de-oxidizing the motor? Internally it is like new. The entire motor seems to have a layer of oxides though.

Thanks in advance!

Fine steel wool and elbow grease, buddy!:-D

Scrubbing bubbles (yes the bathrooom stuff) work pretty well (espicially on powdercoat), dont get it on chrome.

You could also try some of the CLR type products, elbow grease is going to come into play at some point though.

whatever the chem you use, make sure you get a good rinse afterward.

If you can find it (apparently from comments, they are rare) use a very thin flapper wheel on a drill.

Works great! I have been thinking, and am going to try something and get back with folks here about it... take a thicker wheel, like a 1/2" wheel, Soak it in water while still packaged (and thus round and packed tight) and freeze it.
Cut it in half, widthwise, deep in to the cloth. Deep enough to penetrate fins. Polishing compound works great as a finisher, before you use the high temp aluminum polish to keep it shiny.

Thaw, dry, and use that. It will likely do it faster and better than my single 1/4" wheel.

Ok... Thanks for the advice.

I read about this somewhere, mostly for grease and all, but figured it was so silly it might work. So....

I had a can of that no-touch tire spray lying around. Wow. It did not get some of the heavier stuff off without assistance, but it polished up the engine very very nicely. At this point it is ready for some finishing. I tested it out on some fins first, but before long I found myself getting all spray happy.

And I never thought it would shine again.

I recently asked for some Simple Green at the auto parts store, they said they carry some stuff called "Purple Power" and that is a similar product. Well it isn't, becasue I should be using a resperator with the stuff. Anyway, I cleaned my engine cases on the 81, and de-carboned the cylinder head and pistons with it. Use it with a bunch of different size brushes. And if you really want to resurface your engine, scrub with a Scotch-Brite pad. Rinse and good as new!

Gnaht told me he had good results with a angle grinder, i have yet to try this method though :-D

WOW! I am taking a moment from cleaning my GS750L with an old toothbrush and the Magic Purple Stuff. 25 years of greasy kid stuff is going bye-bye.

Alumibrite

Alumibrite

There is a product out there called alumibrite spray it on scrub with a stiff brush and rinse off and it brightens the aluminum.Caution wear gloves and goggle and try not to get it on the paint as it will etch the paint.It can be found at marine shops and probably at truck stops also.

best thing i found to work is kerosen and toothbrush, then spray that with super purple degreraser or simple green, and rinse. then use a scotchbrite pad.

there was a guy in my shop yesterday with 81 gs650l shaftie and he had his engine blasted with co2 there is a company that will came and do. they blast it with isicles the size of tooth picks about 1\4 inch long and no mess, his engine looks great

 

[lord1234]

interesting...would such extremely cold temperatures cause damage to the engine?

 

[akreider]

When I painted my engine I first tried Gunk Engine Degreaser, Purple Power, Simple Green, and Kerosene. But being an impatient man none of those were fast enough. Then I found the epoxy thinner (mineral spirits do not work nearly as well) in the collection of cans gathered over the years and brushed some on the block. OH MY GOD does that stuff cut through the layers of crude. Another benifit is that it strips the old clear coat from the aluminum without causing any damage.

Just remember when using epoxy thinner to wear gloves, ensure proper ventilation (have you ever met a normal painter?) and put down a tarp or something under where you are working.

After you finish stripping the years of crap buildup from the engine, clean it with dish soap and a good stiff brush. Use a garden hose to spray down the engine to make sure that all contaminents are removed. Then dry and paint.

Yea, after reading this I got some work to do

 

[Blueandorangefish]

The place I work at uses ice blasters. It's a pretty interesting method of removal, but I can attest to the fact that it will remove just about anything. Whatever that won't get off a bead blaster with silicone beads will do nicely. I sure wish I had one to blast the paint off my tank so I could repaint it.

Nothing works better on the side cases than "Solvo Autosol" aluminum polish and for the fins, high heat aluminum paint - very quick to dry and the piant on my 850 has been on for over 15 years.

As said by a few - just a little elbow grease too. Have fun rubbing - wax on - wax off! \\/

"OFF" Spray on oven cleaner.
Wear a mask! as the smell is intense.
Try it, it really does work.

+1 on the Autosol......

Watch taht Purple Power on blacktop driveways. it will discolor and disolve the surface. Don't apply Simple Green or Purple Power to a warm engine or allow to sit on a aluminum engine for too long as it will react. Wet the engine before applying it and clean it off completely.

Simple Green is Biodegradeable, Purple Power less so.

I use Lacquer Thinner to clean an engine off, it works too.
