Message: <blockquote data-quote="Skidder Dave" data-source="post: 120634" data-attributes="member: 6952">753H Bobcat - Request advice for blower access.  My radiator blower squirrel cage impeller is slipping on the shaft.  It spins when the engine is running...  intermittently.  I suspect the problem was ironically caused by squirrels storing their walnuts in the impeller cavity, and the impeller demolishes the nuts, with a lot of impact and one heck of a noisy racket, on machine startup.  "Cheat method" - I am able to reach in through the side grills and check the bolt tightness with a 3/4 deep socket wrench and the bolt IS tight - but the impeller is still somewhat loose on the shaft.  Q:  Does the vertical shaft have a flat or key that is supposed to hold the black plastic impeller from spinning, or is it supposed to be "slip-gripped" only by bolt and washer friction against a shaft shoulder???  Q:  If I put more washers, or maybe a conical (Bellville) washer under the nut, will that work to hold the impeller in place???  (I can do those solutions through the side grill - I think, but it's like working thru a mouse hole).  I do have a 753 manual and apparently, I can ("correct methods") access the top of the impeller by A: Removing the oil radiator and also the coolant radiator from over the top of the impeller, or, B.  Removing the hydraulic oil reservoir and pulling out the gearbox along with the complete blower housing, with the cab raised.  Neither method looks particularly easy.  Has anyone in this forum bloodied their nose on this problem???  Am I wasting my time trying to add washers thru the side grill???  Can you offer any "here is the best method to do this" advice???  Thanks in advance for your help!  ****"I spend a LOT more time fixing it, than I do using it!"****</blockquote>
