One of them was to promptly repair seal leaks. Simply installing new seals, however, isn't always the answer. If cylinder wiper seals are leaking, it means that contaminants are getting into the system. One of the things contaminants do is scratch the bore, accelerating wear of the piston seal. This results in internal leaks that silently rob your machine's performance.
Light honing prior to new seal installation makes for a complete repair.
Light honing provides two benefits. First, it renews the sealing surface of the cylinder bore by correcting minor scratched and imperfections. Cylinders can be light hones to .010 oversize while still using standard seals. The resulting true bore and proper surface finish are necessary to get maximum life from the new seals and peak performance from the system. Internal leaks can silently rob your machine's performance.
