I've run into an odd problem with a friend's Cub Cadet 528. It's about a 2010 vintage.
I know it's an MTD product, and I've worked on a few of them. Pretty simple machines overall, but this is baffling.
Back in the spring a I did a complete PM following the factory service manual. He'd never done one, although he had replaced the auger drive belt. In addition to the PM, I replaced all of the springs for the auger as they were pretty rusted. He also had a couple of bent auger blades, so I took the auger apart and replaced those along with the skids and scraper plate.
So, a PM plus a number of repairs.
One thing I noticed during the work was that the auger drive belt was very sloppy and that seemed to slap agains the plastic cover over the drive pulleys. I checked the belt part number and it's correct, weird as it seemed.
I put it all back together and everything worked. The weird thing is that even when the augur handle is released, the auger still turns. It turns slowly, and it will stop if it's run into some snow. My friend insists that it has done this since the belt was changed, so I'm reasonably sure it wasn't anything that I did.
I've looked at everything I can think of. Other than separate the auger unit from the drive (which I won't be able to until spring), I can't think of anything else that I can check.
Is it possible that the auger drive pully (the large one) has a rough enough surface that it's still grabbing the pulley when it's released?
I should mention, that I loosened the auger cable, actually I took it off, to eliminate adjustment.
So, two questions.
1) Is it normal for the drive belt to be so sloppy when not engaged that it slaps the plastic cover. Slaps it hard enough that it chews up the inside of the cover. That doesn't seem right to me and I've never seen it with the Troy Bilt machines that a neighbor has that I've also worked on.
2) What the heck is causing the auger to keep turning when the belt is supposed to be disengaged?
Thanks.
