I have a hustler 48" super duty mower that's keeps spinning out the pulley and fan assembly. Anyone had this problem or a solution to this? Thanks

I have the same model, and have not had any issues. Could you add more information, photos/where/left or right/ when and after how long plus what you do to solve it? I heard there was an recall or upgrade to the 3100's in the fan but not sure this applies to you?

thanks

Can't post pictures but, its the right side and the mower has been doing this since it was a year old (almost 3 now). The problem is where the hub and pulley mesh together. The hub spins inside the pulley wallowing out the star groves and the friction is melting the washer in the bottom of the plastic fan. Have not solved the problem as of yet but, tired of paying 81.00 or a fan assembly. Local dealer is of no use.

DC1,

Find a way to get some photos of the pullies and post them. Have a neighbor or just anyone to help you get them up here.

Also, how old is it and is it under warranty? If under warranty, have you contacted customer service at the manufacturer?

I have the exact same problem and the exact same side! Dealer is no help neither was here...

This first time I had it go I was dragging my driveway the weekend before with the mower and thought the drag was maybe too much for the mower. (sold tooth john deere drag with cement blocks on it for weight) the second time it happened all I ever did was mow. Now I'm on my third pulley and so far so good, but I feel it's just a matter of time.

I've been through over a dozen pulleys in 2 years. Finally had enough with the dealer about a month ago, the Police say I can't go back there anymore! :confused2::confused2::confused2: lol

How tight are you putting the nut on? Dealer told me this last time to run it on with an impact until its tight. Don't hold it there, but until it clicks a few times... So far I have 4 hours on the new one and everything looks good, but it took 10hrs for the last one to melt the fan.. The time before I didn't use an impact and put it on tight, but not as tight as an impact would have.

Hi guys,

I have a Hustler Superduty Fastrak 54" 2012 model. Everything was fine up until I reached about 250 hours of which was about 40% pulling a small trailer with yard rubbish and 60% cutting 5 acre residential property. Very loud metallic rumbling noise which as that time I thought may have been the entire Hydro unit, however replaced the Fan Pulley Kit Part Number 601941 (or for some reason here in Australia the dealer part number is HG72124) and everything seemed fine.

- Then at 307 Hours I replaced the Fan Pulley again, didn't think much of it at the time.
- Then at 335 Hours, again, same noise. thought I had stuffed up the torque setting of the nut on the fan unit on the previous replacement, so purchased another Fan Pulley Kit and pulled out the Torque wench and set it to service manual setting along with Locktight and reinstalled and then all good again ...until now.
- At 379 hours, same noise, same Right Hand side (only ever the right hand side, never the Left hand side transaxle).
There is either a defect with what Hustler is providing as part of the Fan Pulley Kit or maybe Transaxle spline is somehow causing an ongoing damage to the Right Hand side Fan Pulley. I have checked the Transaxle spline and from reviewing the photo's it looks seemingly fine.

Any ideas anyone ?

Bolt the pulley & fan together with cap screws then place the complete unit over the spline and do the nut up nice & tight
If you have a welder then spot of weld one the top of the pins would not go astray.
I can not see any reason why the whole shooting match could not be one piece

I can see where you are going with this option. Like you say, can't see why Hustler don't provide this as a complete single part. Don't have a welder, however will see the next door neighbour to see if he can do a couple of spot welds for me to weld the pulley and the metal piece that goes over the Transaxle spline together. Then surely it cannot wear.

Thanks for the advise / option.

If there is space slip a large washer or plate under the nut to clamp the two bit better and some GREEN or BLUE loktie ( NOT RED ) on the clean threads of the spindle would not hurt either.

Grab yourself an action camera with either a super heavy duty magnetic mount or clean the surface of the area you intend to use the suction cup mount so the camera doesn't fall off. Now, place the tiny camera along with a decent led light in there with you so you can film the drive belt. You're interested in seeing if the drive belt is flopping around excessively causing it to hit the blades of the fan.

If you find this is the case, options are: Heavier tensioner spring (which more than likely will not resolve your problem) add an idler pulley to wrap the belt farther around the pulley that keeps failing. Also check to make sure the two pumps are lined up as closely as possible so the belt isn't trying to ride one side of the offending pulley.

Also, be sure to follow Bert's advice, he is the man.
