Hi Guys: Well I am back working on the HG 42 with a Hercules IXK again. Stamp date on block is 8 -11 - 44.
Noticed that Number 3 and 4 Intakes Valves are defective, severe pitting on face of valve.
The face of the Valves are stamped as follows:
INT
Hercules
27140 A
RMC
Severe pitting exist on the valve face. I am assuming water leakage past the head gasket during the combustion cycle. Very nominal pitting on pistons 3 and 4.
Pistons are marked 3122 A.
Could someone please supply names or sources for
both Intake and Exhaust Valves. NAPA list the Intake Valve as being available. No Exhaust Valves are listed.
I was thinking Landis or Ray probably have them and perhaps Jerry Biro. Guess, I will be checking all the valves after what I found on the intakes on 3 and 4.
Do any of the IXK experts have any additional sources for valves and does anyone know what the initials RMC on the face of the valve stand for?
Thanks! Orangeman
RMC made the valves. Napa also purchased the valves. Right now I am trying to remember the vendor. Do you have the block out? Might be a good time to install valve seats especially for the exhaust valves. Jeryy has them.
Hi John: Thanks for the reply, I was at NAPA yesterday and yes they do list only the intake valve. They are still relying on the old 2000 Industrial Engine Parts Catalog. Seems that as a company they would have taken a crack at updating the catalog.
The engine is not out of the machine. I will check the seats when pull the valves to clean up the valve chamber. So thanks for the reminder.
Hope your summer is going well!
What I have done is take one of your intake and one exhaust valves to a shop that rebuilds engines and go through their scrap bin. Many times you can find perfectly good used valves that are exact matches that you can get for practically nothing.
It's how I learned that Mack (forgot the engine model) intake valves will work perfectly in a 28-50 Hart Parr tractor if you use the Mack keepers.
And that John Deere M valves will fit in a Caterpillar Ten.

Blake: I have done half of that I redid a 12-24 hart parr and used all Mack valves including stellite exhaust valves and rotaors. I have a spec book. I will check out the IX valves between now and the weekend. John
Checked with NAPA, allowed two weeks to pass, could not obtain valves either intake or exhaust.
Went to specialty machine shop, same conclusion.
Called Landis Zimmerman, had Valves within four days.
Conclusion, Zimmermans has what you need with Good Service.
Thanks to all those that posted. Appreciate your efforts.
Take Care! Orangeman
