I think you have to be, it connects the engine to the hydro pump via the driveshaft (no longer in unit ) I don't believe the universals would hold up to the wobble it would subject them to, I thought it would have at least taken out the rear seal yet its been running several times and setting in the same place for over 24 hrs and no drips, it's a shame because it is a nice sounding engine That tractor and its' weights want nothing to do with you... you have history.. :poke:Thought the same thing, serial number and specs number put it beyond the bad oil pump era on the 532's , pretty much the fact that its a 2087 with the plastic dash and PTO brake did as well. It's a shame, the engine sounds really good.
I wasn't aware there was an era of bad oil pumps on the k532. The id tags are gone from my ht20. Are there other ways to tell? I was thinking of doing a rebuild on mine this year, though they horror stories of the busted cam shafts after rebuilds has me hesitating. I should start a new topic on this though.
