Check on ebay for part.

There may be a member on the site that has a spare arbor. I am not sure if there is a difference between the 42" deck arbor or a 48" deck drive arbor?.

Sorry Earl, but I sold my only remaining center arbor to "Bunky". The part# for the arbor is 21085004SM.

Your deck appears to be the older version with "keyed" arbors, the newer products have "spline" arbors.

It is available on Partstree @ $52.

May I ask, The only "break" I can imagine is you sheared the threaded end portion by over torquing* the top jam nut. Am I correct?

Torque spec for a 3/4-16 nut = not to exceed 180 foot pounds!!

id="quote">Mark,The original part#s for the center arbors are different. What the difference might be IDK, perhaps the length(?).

The reason I asked is I thought I might have one for the 42" deck.

You are correct, The length would be different due to a deeper deck.

Thanks for everyones help. I was mowing through corn husk that had blown in the ditch and the arbor broke where the setscrew tightens to the key. It took a big chunk out of it. I'm thinking it must have been loose. I took the deck off another tractor I have which needs a coil due to the end of the muffler blowing off and I kept mowing, which than melted the coil. I need to do a lot of repairs.

The arbor has a keyway in it and the pulley bolts on with three bolts.

would Sandy Lake have that arbor?
