WARNING CAUTION Original pushrods must be cut with boltcutter. If cut with saw, metal chips may enter the engine and cause extensive damage not covered under warranty. S&S recommends replacing stock pushrod cover retainer clips and aluminum inner covers with S&S covers for increased stability.

They can be installed and removed without removing the gas tank and rocker covers if the original pushrods are cut for removal. Allow 5-10 minutes for lifters to bleed down. After lifters bleed down and pushrods can be turned with light finger pressure, extend pushrod covers and install S&S® or similar retainer clips. CAUTION Rotating engine before lifters have bled down may damage pushrods and other parts. 11. Start engine and observe for leaks.
