Theoptional side load adaptor provides long lasting solution. Secure the side load adaptor with Loctiteor lock nut on the shock absorber. Material: Threadedbody andplunger: Hardenedhigh tensile steel. Hardened 610HV1. Note: Material that impacts the side load adaptor shouldbehardened to a similar value.We recommend that you install the shock absorber/side load adaptor using the threadon the side load adaptor. Problem: Rotating impactmotion causes high side load forces on thepiston rod. This increasesbearingwear andpossibly results in rodbreakageor bending. Solution: Install side load adaptor. Maximumangle: 250-0141, 250-0145, 250-0146, 250-0562250-0762=12.5° 250-0554,250-0561, 250-0763=25° Note: By repositioning the center of the strokeof the side loadplunger tobe at 90degrees to thepiston rod, the side load angle canbehalved. Theuseof an external positive stopdue tohigh forces encountered is required.
