The spindle housing (mandrell) came as advertised but with no 'tapped' holes for bolting to the mower deck as had been the case with the OEM equipment. Further, the mounting hole bolting area was compromised by the mis-alignment of the two pieces that made up the housing and smaller bolts had to be use to mount the unit. This oversight in MFG cost me an additional $8 dollars for mounting hardware and over an hour to get to the hardware store from the mowers remote location. At the very least a notice should have been noted on the web-site indicating mounting through-bolt hardware was required for assembly. Once assembled the unit worked as expected; however, because of the lack of tapped holes, I'll have to check and recheck the security of the mounting bolts with every use of the mower. Will it work, yes. Is it acceptable, no.
