B17 on engine parts

Post by diaz1510 » Tue Feb 13, 2018 6:00 am

OK, first time B17 user, so be gentle, LOL.

I got a pretty good setup for stripping and rinsing. I'll be stripping a bunch of motorcycle parts but my question is regarding the engine components. Specifically the cylinder jugs of a Harley Twin Cam. I know it will strip the powder coat just fine, but my concern is the interior of the cylinder jugs. If I dunk it just long enough to strip the powder and rinse it thoroughly, will the cylinder interior be fine without having to hone them or anything? Or would I be better off brushing this stuff on? Everything is aluminum, except for the cylinder liner.

Thanks in advance.

It’s gonna Rust, but if you rinse and dry it quickly it will be fine then after coating just use some wd40/oil something to Coat the sleeve until you get it back together..

As Herb said - it will flash rust no matter what.

Don't sweat the time in the stripper, that's not what causes it to rust. You want to give it plenty of time so you don't have to work to get the coating off as you are rinsing. I use a pressure washer. It won't start to flash rust until you wash it, and it won't do that immediately either.

Rinse it well. Any B17 that is left on the steel will cause more flash rusting as it dries.

Wipe the bore dry immediately, but I would put anything on it until after it's coated.

Probably to late but I would run them thru a oven cycle to bake out any oil and or stripper that might have seeped in between the cylinder sleeve and the cylinder housing. I know most will say never gunna happen but I have had many times oil bake out once heated. Weird I know but better safe than sorry.
