How are main bearing caps measured and inspected?
The main caps and journals are inspected and measured before replacing the worn bearings. The main caps become oval from the intense downward pressures imposed on them by the engine’s crankshaft. Inspection: A line boring tool bores the main bore through the bottom of the engine block and the main bearing caps.
What is the role of bearing end cap?
Bearing end cap, as one of the most important mechanical parts, is widely used. The main working surface of the part is the outer surface of the left and right end faces and the left end face. The majority of small and medium-sized reducers use rolling bearings, and the bearing end cap of the rolling bearing is the most common part.
Do you need to remove the bearing cap?
To replace main bearings, remove the bearing cap and take out the worn lower shell. You should remove the main bearing cap and pull the oil seal out.

Which is the best cover for ball bearings?
Yellow ABS caps stand out from darker equipment, reducing the risk that someone could accidentally get caught in bearings. PETG caps are clear, so you can visually inspect bearings without removing the caps. Lg. Wd. Ht. Max. The lubricant in these mounted ball bearings is suitable for incidental contact with food.

Why are the bearing caps on an engine oval?
The main caps become oval from the intense downward pressures imposed on them by the engine’s crankshaft. Inspection: A line boring tool bores the main bore through the bottom of the engine block and the main bearing caps. Each cap is bolted in place during the process. It isn’t perfect, especially toward the end of the boring process.
