i have a exmark turf tracer, i believe my right pump is going bad. yesterday while running in 97 degree heat for about 3 hours straight my right pump started making a racket. it just started all of a sudden. it seems like the more i idle it up the less sound, or the engine is louder and i cant hear the clanging. or is this because its not getting enough oil? maybe my hoses are collapsed, or a valve stuck? if not this then i figure the pump is going bad. i just had a new clutch and wiring harness put in. my local dealer did it and when i realized a month ago the clutch is going, he said run "it till it dies". so i did.... do i do the same with the pump? if its going bad?
