description

This 8S-1491 is thin steel lock plate for camshaft thrust plate assembly. It secures the fixing bolts by bending tabs to prevent loosening caused by vibration and thrust plate shifting. Made of cold stamped steel with good toughness, precise thickness will not interfere with axial clearance. It fits 3304 and 3306 engines on wheel loaders, motor graders and generator sets. It is a mandatory replacement part during camshaft overhaul.

FAQ 

Q1：Can intact 8S-1491 lock plate be reused after disassembly?
A：Not recommended. Bending area has stress and will fail quickly on second use.

Q2：What failure will happen if lock plate loses function?
A：Thrust plate bolt loose, thrust plate shift, camshaft axial movement and timing drift.

Q3：Is this lock plate the same as thrust washer?
A：No. Thrust washer bears axial load; lock plate only locks thrust plate bolts.

Q4：Should I replace this lock plate together with new thrust plate?
A：Yes, it is disposable locking component.
