Polaris Vac-Sweep 380 / 360 and “Trade Series Exclusive” TR35P / TR36P Pressure Cleaner Lock Washer, Axle Block (9-100-5130)

The lock washer, and axle block is replacement part made by Polaris. The same high-grade materials were used for the original factory part. Making this a certified OEM product.

These lock washers are designed to slide onto the 4 screws (8-32 x SS) that help lock in the axle block kit (both front and rear) to ensure they are not able to move. If they were to move or adjust in any way this would ultimately disrupt the cleaning process, making the pressure side cleaner ineffective.

These washers are a copper-like color making them very easy to identify. These parts can deteriorate over time or can be lost due to their small and thin-sized capacities.
