1、Applicable Model: Bucket pin shim is fit for 65mm pins, such as replacement for Case 9013, CX130, CX135, CX135SR; replacement for CAT 311, 311C, 311D, 311F 2、Hardest Material: Bucket pin shims are made of the strongest engineered polymers, with low friction and high wear resistance, reducing friction losses and extending service life. 3、Multifunction: Shims make loose joints tighter, from the bucket to the boom, improve the stability and performance of the overall equipment; Increase grease spacing; And prevent dirt from entering the bucket pin. 4、Increase Lubrication Interval: Bucket shims prevent the loss of grease due to loose joints, reduce maintenance frequency and cost, save time and effort. 5、Stop Dirt from Spilling: The most worn pins are those closest to the dirt, and spacers prevent dirt from spilling into the bucket pins, extending life.
