Went out to do my final mow of the season this weekend. I hit the PTO switch on my GTX18 and heard the belt squeal and no blade movement. thinking I probably just had a twig jammed in the blades again I jacked up the tractor to investigate. Hmm, nothing under the deck and I can sort of move the blades by hand. I then took the belt off to check each blade individually thinking I probably have a seized spindle bearing. Sure enough, one of them will barely spin and then I noticed that the spacer that sandwiches between the blade and the spindle housing is broken. I decided I might as well pull the deck and check them all out. The other two spindles seem ok, though one had a cracked spacer. the housing on the seized one looks like the spacer continued to spin and ate into the housing.
So I guess I'm going to replace the bearings in all three spindles, along with the spacer. Last year I replaced the tensioner and idler pulley along with a new belt. Looks like I'll be finishing the rebuild this year. I ended up mowing with my trusty Honda push mower. 13 y/o and I've only ever had to change the oil and put gas in it.
Does anyone happen to have a used spindle housing? Part number is 1765092, 1769048099, or 1769048. I might be ok with the one that got damaged, but if I can find a used one to replace it I might as well.
FYI, the bearings are p/n 1185574P and the spacer is 1765029. Both are readily available from many sources.
