Please don't trash the old rockers and shafts- - - - -they can be refurbished. I regrind the shafts to a smaller diameter (18MM) and ream the rocker arms for Torrington needle bearings. Drop me a private message, and we can discuss shipping costs, etc. to get the "discard" parts recycled. Thanks!

The top ends of the pushrods are the most common failure areas. The cupped part where the rocker arm adjusting screw fits can wear unevenly, and cause damage to the adjusting screw- - - -resulting in inaccurate valve lash. If the rocker screw tips have a projection worn into the middle, they will cause wear or damage to the top cup on the pushrod, and sometimes even break the cup area.
