Questions & Answers

This idler pulley is plastic and the bottom flange has broken off. I would like to get a metal replacement if I can. I can not get the pulley off of the threaded shaft to measure it. Do you know the dimensions (bearing bore, thickness and and running o.d).or know of a metal replacement that I could purchase? Thanks,Fred

Hello Fred, thank you for your question. Unfortunately, there is no replacement for this part in metal. Everything is cataloged by model number in our system, so we unfortunately do not have the specifications of this part.

Completely rebuilt the deck, everything was worn out.
Dissembled deck completely and reassembled with new parts. Diagrams that came with parts were very helpful. All parts fit better than new. Deck cuts better than ever. I saved a lot money.

Nothing ! - got the parts for my winter overhaul yet to be done
Great service from you guys, really appreciated it - my old (1991) model Murray mower is still running fine, (one his third mower deck and probably 10th set of blades!)
I needed a left hand headlight lens (part 91319) but so far haven't found one - got the right hand lens and all the other parts aok, so looking forward to the winter overhaul in the shed - if anyone has any idea where I can get the lens I need, new or second hand, would be great to hear !

Cheers
Kelvyn
