Dec 1, 2019 | CYLINDER HEADS

We have used a Lisle hand held keeper installer tool to assemble small import heads for many years. It can be hard on your hand pushing on the tool to get the keepers to seat, especially on aftermarket springs that are stiffer than the originals. But it is much faster than using a spring compressor. It occurred to me that the tool would work just as well mounted in the seat and guide machine and it’s much easier on your hands! Pre load in all your springs, retainers, and keepers, then go right down the line and pop them together. This head went together in minutes.
