So GSR/ITR bearings have this fancy coating on the rod bearing, pic below. This fancy coating will be trashed after scraping off the crushed plastigauge. Any problems with scraping off this coating?

You should not be "scraping" anything off your bearings. Any form of "scraping" that is harsh enough to remove a coating off the bearing is far too harsh. Perhaps you should be a little more careful and come up with a new method to remove the crushed plastigague. You do know that you can leave the crushed plastigauge in there (unless you need to reclearance) and it won't hurt anything, right?

I haven't plastigauged the rod bearings yet, that one is straight out of the bag and as you can see the coating is very delicate (couple of places where the coating has touched something and flaked off). Hence the my post before I do proceed.

I did not know that the plastigauge can be left on, as this goes again conventional wisdom to keep everything as clean as possible.

Any other opinions/insight out there?

The plastigauge will wear off as soon as the crank is turned after you have torqued the bearings. I have never had an issue leaving the plastigauge on there. To be honest, I do my best to remove the larger sections, but I never scrape the bearings to where I damage the coatings. The initial outter coating on most bearings is very soft and easy to scratch.

 

that coating does nothing. its from the manufacturing process. will be gone after a few revolutions.

 

The trick is to make the plastigage stick to the crank and not the bearings. Then there no need to scrape da plastigage off da bearing.

PAM fo da win!!!

Wish I knew this before I started but anyways the plastigaging went well. The fancy coating dissolves when assembly lube is spread on the bearing.

 

A little brake cleaner on those blue shop rags do the trick to, just be gentle and you'll be fine!

Always told solvents are a no-no for bearings. Oiling the bearing plus scraping with a finger nail FTW. Make sure the finger is clean!!

 

i just leave the plasticgage on there. it'll be gone as soon as you start the motor, and it IS oil soluble, so don't be worried.
i wouldn't scrape the bearings, though.

 

How guys checking crank fitment (the turn da crizzank and feel resistance by hand) wid da p-g in dere?

Cajuns wanna kno.
