description

This 522-3138 limiting plate is fitted between camshaft gear and thrust structure. It works together with thrust plate to control camshaft end play and share axial load, stabilizing gear meshing and avoiding timing shift caused by gear wobble. Made of precision stamped low alloy steel with double-side ground and hardened surface, it is extrusion resistant and not easy to warp. It fits the same series CAT engine camshaft assembly, replace on demand during timing disassembly and inspection.

Part No.：522-3138
Name：CAT 5mm thick plate
Thickness：5mm
Material：Carbon Steel
Treatment：Double side grinding + surface hardening
Matching part：522-2827 thrust plate

Application：CAT 320D3 GC 320D3 excavator

Advantages

• Provided with 4 mounting holes to fit a fastener of size M8.
• Manufactured to a precise specification and are built for durability, reliability, and productivity.

1. Tight thickness tolerance, standard adjusting plate for accurate axial clearance setting
2. Double ground working surface, low friction coefficient, less heat and wear
3. Good toughness alloy substrate, resistant to deformation and cracking under alternating axial load
4. Combined with thrust plate to distribute pressure and extend service life of whole thrust assembly

FAQ 

Q1：Can 522-3138 replace 522-2827?
A：No. They have different functions. 2827 is main thrust plate, 3138 is limiting adjusting plate.
Q2：Can we stack multiple 522-3138 plates to adjust clearance?
A：Stacking is not recommended. Multi-layer plates tend to wear unevenly. Use proper shims.
Q3：Can plate with light scratches be kept in service?
A：It can run temporarily without grooves or warping. New replacement is recommended for overhaul.
Q4：Which side should face the gear during installation?
A：Both sides are identical, either side is acceptable as long as flat contact is secured.
