Starting to do DFL (Dry Film Coating)

Ever pull apart an engine and you look at the bearings and say to yourself "those look good, I bet I could reuse them..." but you don't because the are stained or have the odd speck in them?
Well these puppies are getting expensive and some are hard to find.

For the most part you don't need expensive measuring tools to figure this out, you just need eyeballs and fingernails.
If it has obvious physical damage, wear through, pitting, material missing or large scratches you can catch your fingernails on, then sorry you need new bearings. Minor scratches down the middle that you barely catch a nail on may be OK.
Also look at the backs, loose bearings will "walk" scoring the back. Again stains are OK, physical damage is not. Also when you remove the bearing does it just fall out (not good) or does it still hold itself in the saddle (good sign) and you have to wiggle it out.

On Porsche 911 I'd say 9 out of 10 of the #8 bearings can be reprocessed.

Used main bearing set

Not offering this on type 4 bearings (except I will do the steel backed split middle) at this time.
This may change once I test a process.

Piston skirts and ceramic piston coatings coming soon.


Inspect and process full 911 engine bearings set (main, #8, rod and intermediate bearings, new or used) $175
Turn around 2-3 days.
