Yeah, that's what the standard product runs. We keep all mill spec on our product for the last 20 years, along with all clearances for each pump and gear set since it's 100% inspect. All we need is the serial number to verify.So I just tested my unused Boundary OPG and below are the results. The tester is within calibration and was verified with a calibration block prior to the tests.
Martenwear gears use a progressive heat treat that surface hardens the gear to hrc 55-60. Those run 299.
I actually think for a core and good wear surface hrc 30 to 40 is ideal. The gear will deform before cracking if something large gets in it giving you time to shut it down.
Most of the gears you see damaged on the market are caused by debris, but some are clearancing issues or hardness related.
From our research
16 to 30 is 8000 or less
30 to 40 is 9000 or less
40 to 50 11000 or less
And our Martenwear have tested out to 13,000 which is 55+. We haven't found any takers going higher.
These can vary because of two step use, line lock, heavy crankwalk caused by extreme levels of forced induction.
If anyone has any questions happy to help.
