1850 crank pulley on Perkins

young tractor · Jan 24, 2022

Hi guys thanks for all of your help on the previous post. I originally pulled the tractor in the shop to reseal the power steering cylinder. Its leaking. I watched the Chris losey video on how to do it. He mentioned that on Perkins engine that the crankshaft pulley needs to be removed to get the steering cylinder out to rebuild. Is the front crankshaft pulley like my 1755 where the seal rides on the crankshaft pulley. Im nervous to pull the pulley and then put it back together and the crank seal then leaks. Is there any way around removing the crank pulley? Also am I better off unhooking the oil cooler lines and removing the oil coolers with the radiator or can I in bolt them from the radiator and lay them down. Thanks for your advice.

Thanks j Schwiebert. He talked to me again on the phone to help me out. He is a great asset to have on this site. To take the time to help people like he does speaks volumes to who he is as a person. Thanks again for your help.

So what was the answer? Does the front pulley have to come off? I know I've had the gear and shaft out of mine without taking the pulley off, and I had the whole thing off at least once, but that was likely when I had the engine out. I can't say with certainty that I've had the whole thing out with the engine in. I know that I had to take the pulley off the White 2-135 to get the cylinder out of that when it started leaking bad. I've had them out of the 1550 and 1600 and they lifted right out.

We discussed a few options in case it does need to come out. One possibility was to take the small bolts out of the dampener and just remove that. Or if possible take the shaft up and out of the steering cylinder. Im going to dig into it this weekend.

That's kind of what I was wondering, about taking the shaft and gear out then tipping the cylinder to get it out. I broke the shaft once and pulled the shaft and gear. I think I changed the quad ring in that one maybe and pulled the shaft and gear again. I'm pretty sure I rebuilt the whole thing once, but did it when I had the engine out. That's the problem with having several different models around, I can't remember what I did or when to which tractor. I wonder about taking the front motor mount bolt out and loosening the ones in back and just jacking up the front of the engine barely enough to get the cylinder out. I think you'd have to take it up a fair distance to damage the PTO shaft. I'd hate to tell anybody to do it though and be responsible for somebody doing real damage.
