1977 B-80 36 inch mower deck pulley

[stvski80085 37]

Hello again,

I am trying to find the manual for my mower.  It's a right hand discharge 36 inch mower.  The tensioning pulley is bad.  Can't replace the bearing on this one so it looks like it's one unit. Second question, I guess there is no grease fitting on the main bearings.  Not sure what the name of the 3 main shaft's are.  Do you have to take them apart to grease them up.  I'm pulling the whole thing apart to clean and paint the deck so if I do no big deal.  I think I could drill and tap a grease fitting into each of those unless that's a bad idea.

If you search our files using a model number as written above and look at ones with IPL in the title there is a breakdown of the different spindle assemblies used on that deck. The first one is the original.

An example. Click on the fuzzy picture in the link below and click the thumbnails to enlarge.
