CAT Engine Parts Camshaft Bearing Set 4P-8495 4P8495 3406 3408 3412 for Excavator

This camshaft bearing, part number 4P-8495 (also written 4P8495), is a direct-fit replacement bearing for CAT 3406, 3408 and 3412 diesel engines. It is the component that supports the camshaft journals inside the cylinder block and keeps the valve train running on the correct centre line, so oil clearance, cam timing and valve lift all stay within specification. As one of the fast-moving CAT Engine Parts in any rebuild programme, the 4P-8495 / 4P8495 bearing is ordered in sets by engine rebuilders, fleet workshops and parts distributors who service excavators, wheel loaders, track-type tractors, motor graders, off-highway trucks and generator sets.

• OE-matched bore and wall thickness for CAT 3406, 3408 and 3412 camshaft journals, standard size installs without line boring
• Steel back with babbitt lining gives high load capacity and stable performance in continuous duty engine operation
• Oil holes and finished oil grooves are machined to the original layout, keeping lubrication reliable at idle and at full load
• Controlled crush height and wall tolerance hold the oil clearance inside the recommended band after tightening
• Every 4P-8495 4P8495 bearing is checked for roundness, surface finish and burr-free edges before packing
• Supplied as a complete set for one engine, so a full camshaft bearing replacement is done in a single step

The 4P-8495 4P8495 camshaft bearing fits CAT 3406, 3408 and 3412 diesel engines in both naturally aspirated and turbocharged configurations, including the common 3406B, 3406C, 3406E, 3408B, 3408C, 3412C and 3412E builds. These engines are found in excavators, wheel loaders, track-type tractors, motor graders, off-highway trucks, pipelayers and generator sets, which is why this camshaft bearing is a repeated item on maintenance schedules and overhaul parts lists.

• Correct fit for 3406, 3408 and 3412 engine families, reducing downtime during in-frame and full rebuilds
• Consistent batch quality, so workshops can standardise on one part number for several engine models
• Stable oil clearance helps protect the camshaft lobes, lifters and valve train after assembly
• Clear identification by both dash and non-dash part number formats, avoiding picking mistakes in the warehouse
• Practical packing for container loads, pallet orders and small trial orders
