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 ?
