Hello, I have following question. Give me an advice what kind of tool should I use to install retainer for pushrod (Evo engine). When you want to mount retainer for spring cover what is the best tool to do it. Using just hands it is very difficult (maybe for strongman not). One time I used large screwdriver but it was also not so easy. Look at this film on youtube: Harley adjustabl pushrods, N-gin - YouTube The guy is using (time 4:15) wrench (what size??). He put on it a rag. But maybe you can advice me is there any special tool, not just wrench, to do this work. How to make it, etc.
