What does Melonized mean?
“Melonized” is a process well explained by Mike532. It’s supposed to make the surface harder and therefore more resistant to the wear of dissimilar metals when one is harder. Like a steel roller cam.
What to know about improper distributor gear selection?
COMP Cams’ Dan Hodgdon started off by saying, “There are several trouble areas that may arise due to improper distributor gear selection. First of all, it is imperative that shimming heights are correct, meaning it is critical for the distributor gear to be centered to mesh properly with the cam gear.
Can a high volume oil pump cause distributor gear wear?
Davis agreed, “Excessive distributor-gear wear can be a problem with Ford engines. Most of the time, the problem again results from the use of a high-volume oil pump. High-volume oil pumps put a lot of stress on the distributor and cam gears. A high-volume oil pump is not necessary on a street-driven engine that turns no more than 7,000 rpm.”
Why is distributor gear better than cam gear?
Selecting the improper gear can lead to premature camshaft wear.” “Ideally, your distributor gear will be softer than your cam gear. This allows for proper mating and prevents excessive wear on the cam gear. Most cams come with multiple distributor-gear options.
What kind of distributor gear does a flat tappet use?
Cast-iron distributor gears work well with most cast-iron flat-tappet camshafts. We checked with several distributors and camshaft specialists to get the lowdown on gear meshing and materials in this often-overlooked maintenance procedure.
