I have the chance to get some 6202 C4 Nachi bearings for relatively cheap. Anyone have experience with the c4 vs the c3?

I understand the c3 is rated plenty high rpm/tolerance for the 372 these bearings are going into, but is the higher rpm/tolerance going to cause any issue? IE rate of heat expansion (or lack thereof) on looser tolerances?

5105 needed some cleaning (carb, oil pump and lines)
Slapped a NOS bar on it and some square chain.
Needs a muffler mod (cat delete)

All I had nearby was some cedar but it didn't stand a chance...

Yes NY saw...
Chain I found by accident looking for a loop of appropriate length for the nice NOS bar I had...
Didn't even know I had it....
It's kinda butchered up but it's a start towards the square thing....

C3 are already loose tolerances as far as bearings go. I think c4 might be too loose

Just finished port work on @crackerbuilt MS661. Waiting on the rest of the parts to assemble. Here's what we're starting with IMG_2819.JPG
How fitting a former chef receives a box of busted saw in a restaurant dish tub. Lol! Steve got this saw for free. It has about 20 minutes run time. Shouldn't be a stretch to figure out what happened :facepalm: Here's some port work pics. I'll post an update when everything is here to assemble. IMG_2813.JPGIMG_2814.JPGIMG_2815.JPG

Bus tub to beauty. Like it never happened ;-)IMG_2825.JPGIMG_2826.JPG
Waiting on a maxflow from HLSupply and forgot to order the handle cover that goes behind the clutch cover. Had the cylinder on by 4:30. A few random pieces went missing and had to comb my parts stash, then fought a few pieces that had to be "massaged " to fit.IMG_2821.JPGIMG_2822.JPG IMG_2824.JPG

Case fit was dead nuts up front and off a whisper off in the back. For those keeping score on the QC front. Took .035 from the band and .020 from the base. Factory gasket installed with .020 squish. Muffler mod tomorrow. Time for an adult beverage
