RPM 1,190 Report post Posted June 16, 2018 On my thrust damage to the crank and bearings, a couple of fellas believe excessive high pressure in the fmx causes thrust damage like mine. I've searched high and low to find a high pressure port to hook up a psi gauge on the tranny to check pressure. I'm hoping we have at least one knowledgeable guy here who has some good info for me. Thanks Quote Share this post Link to post Share on other sites
MAC390 327 Report post Posted June 16, 2018 Just looking at the factory manual under general transmission service. For a FMX hydraulic bench test you put a pressure gauge in the 1/8 pipe plug fitting at the trans case. You have to turn the front pump in a clockwise direction. They say turn the front pump at 75 to 100 rpm and check the pressure against the specs. Don't know if this will help or it's crap Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted June 16, 2018 Thanks Mac. So how does one measure 75-100 rpm? I received an answer from Ken Collins on his Bad Shoe fb page. The port is located forward of the shift linkage. Quote Share this post Link to post Share on other sites
MAC390 327 Report post Posted June 16, 2018 Hey Bob, i have put the pump shaft in a lathe and spun it at low speed. Quote Share this post Link to post Share on other sites
