What does the main bearing caps do?
Bearing caps contain the main bearings of an engine’s crankshaft. As part of their required processing, bearing caps must undergo a tough splitting operation, requiring strong and stable operations. Tooling for bearing cap machining is highly complex and often custom in nature.
What are bearing spacers?
Bearing spacers are small metal cylinders that fit into a skateboard wheel between the bearings. Their purpose is to reduce the weight distributed to each bearing, which can make your turns smoother and more stable and also extend the life of your bearings. For example, 8mm x 10mm is a very common bearing spacer size.
What is a main cap?
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.
How do you measure a shim?
Standard measurements of shim sizes include the following:
- Size A: 2″ X 2″ with a 5/8″ slot.
- Size B: 3″ X 3″ with a 13/16″ slot.
- Size C: 4″ X 4″ with a 1-1/4″ slot.
- Size D: 6″ X 5″ with a 1-5/8″ slot.
- Size E: 6″ X 6″ with a 2.00″ slot.
- Size G: 7″ X 7″ with a 1-3/4″ slot.
- Size H: 8″ X 8″ with a 2-1/4″ slot.
How do you calculate shim thickness?
The equation you’ll use to determine the new shim size is as follows: New shim size = (measured valve clearance – specified valve clearance) + old shim size.
