I replaced both front and rear drive belts (confirmed MTD belts) on a 2000 MTD Yard Machine, Model 13AK673G088, with variable speed drive. First problem was not being able to get the crankshaft pulley lowered in order to remove the front belt and accidentally bent the upper pulley a little in the process. I tried to straighten it back as best as possible but it's not pretty. I wound up bending one of the tabs on the frame around it in order to get the belt off and replaced. After that I bent the tab back.
The next issue I had was that the mower wouldn't stop completely. I followed the manual to adjust the brakes and both linkages for variable pulley and brake. After adjusting, I finally got it to stop, but the front pulley is slipping and heating up. Is it normal for the front pulley to slip when the clutch is engaged? I can't help but think either there is some mystical perfect alignment of all the adjustments for this to work with no tolerance or I messed something up on the pulley. If the latter, I don't know how to get the pulley off to replace. I tried using a pulley puller with no luck.
