what is the difference between an oversized rod bearing and an undersized rod bearing

Undersized bearings compensate for the amount of material removed during this machining process. #menu ul ul li { Undersize bearings have more metal on the inside of the shell meaning a smaller diameter internally when the 2 shells are put together.Used when the crank is ground down. It's far less expensive (than $11 per bearing HALF from Honda), and works just as well. For instance, if a completed bearing measures 3 inches on the outside diameter and has a stock metal thickness of 0.20-inch, then its inside diameter will measure 2.40-inch.

I have used oversized rod bearings and had the crank micro polished after it was ground with no issues. This procedure involves bolting the mains to the block and running a big cylindrical cutter through all of them.

No trouble in 8000 miles (1.5 years, just don't drive much). Bearings come standard, oversized, or undersized. Im not being hard headed Im just trying to tilt your heading in a slightly different direction of thinking... we aren't dealing with SBC or BBC or SBF..... these are Subarus where just like you said cutting mains isn't common. I shouldnt have referenced the hx as oversize above but technically it is oversized when measured to the crank journal. An oversize, but check with plastigage at 90º angles to be sure that the rod pin is not oval. The crank shaft face is very good so i can not justify stripping them for a regrind, the engine was running well before the piston ring went. Which would give you more clearance on a stock journal. req.send(null);

What are some mods i can do to make a suv handle a little better? This chat is about membership and for login-issues, no technical requests please!' Bearings can and do spin in the block sometimes, but more often than not, oversized bearings find use in blocks that have been line-bored. I measured it with a plasigauge and sure enough, it has been worn out of spec. Thanks Agrimax, So does undersized bearings actually mean thicker bearings?
