There needs to be a correct relationship between the components of the valve train to allow an efficient transfer of the cam lobe information into valve motion. This relationship is often referred to as the valve train geometry. On many OHV engines the geometry is adjusted by changing the length of the pushrod. A large number of variables are involved in determining the correct length pushrod for your application. Pushrod length is affected by any of the following: | There needs to be a correct relationship between the components of the valve train to allow an efficient transfer of the cam lobe information into valve motion.
