Steel billit solid roller , bronze or Melonized gear

[fy469rtse]

gears ? Bronze or Melonized , oil pump drive shaft , any one had any success trying the new Melonized gears , inspected mine , bronze and showing wear pattern ,
3 rd one , just when I thought this had settled , run in etc
Ron or challenger340
would be the guys if any that have had experience with these,
Thinking on compatibility of these steels , what is the process involved manufacturing Melonized ?
There's lots of post regarding MSD melonised gears and GM product on other web sites

Or composite gear from comps, states for R 5 engine ? Is this a race only application
300% increase in wear rate over bronze

I've only used the bronze gear on a billet roller cam core....no experience with the others. Usually accelerated wear indicates a thrust/endplay problem

Or a HV oil pump that's causing undue load on the drive gear.

end play checked Ron , thanks john , yes was going to put standard pressure pump in next, yes high volume pump
just disapointed that in my research on this engine, that this didnt flag like a bull in a china shop , to me anyway
went with the high volume thinking a lot more oil to this area couldnt hurt
melonised gears on forums keep popping up in discussions mainly on GM stuff , and keeps me wondering ?
