We asked the bearing brainiacs at Mahle for some tips on fitting engine bearings. The first thing they emphasized was the importance of getting an accurate measurement. “When measuring bearing measurements, they should always be taken at 90-degrees to the parting line to determine the minimum clearance. If measuring the bearing wall thickness, use a
This week in our Mailbag, the Summit Racing tech department is troubleshooting bearing-clearance measurement and engine-cranking issues in a small block Chevy. Q: I’m building a 350 Chevy engine and have a problem. When I torque the main bearings down, the crank is very hard to turn over. When I install the connecting rods, the starter
“Upgrading even the most basic engine parts like engine bearings can give you a great performance advantage,” said Summit Racing tech expert Norm Koval. In this short tech tip video from Summit Racing and Powerblock TV, you’ll hear Koval explain how specialty coatings which reduce friction, and include certain machined design elements give performance bearings
