mower deck spindle part number

[MSZ40 7]

Hello, long time wheel horse owner, started with a used B-80, sold to family member to purchase a new 312-8 in 1996.  Divorce seperated me from that one and 10 years ago I bought a used 314-8 with 42 side discharge deck.  Spindles are noisy and need rebuild. Can't find any tag or part number on deck so looking to get correct spindle bearings.  This 3 balde deck is not original deck either.  Any help appreciated.  Also have a snow blade and many parts like new for an un-used mold board plow.

Thx

Mike

42" deck---  Model # on the deck?  OR--- Do the top pulleys have a key-way slot in them or not?  Take off one of the top nuts to see.  OR----what is the dia of the TOP spindle shaft---3/4" (bng pair # 106084 & #106085)  or 5/8" (two # 109966).   I ask b/c there are 2 spindle styles of the 42" deck and bearing are different.

If it has 5/8" nuts on top of the mower spindles the bearings are metric 6203  ( 40mm OD  17 mm ID and 12 mm thick.) That is what should be on a 314-8 if it's the same model deck. 

The older decks with 3/4" nuts on top of the spindles also used a 6203 bearing with ( 40mm OD  3/4" ID  and 12 mm thick. ) 

The old Double D spindles have a 3/8" bolt on top of the spindle with a compression washer.  Blades and compression washers are hard to find for the old Double D  decks and suggest newer metric spindles.

All three types will bolt on I have had all three on my deck in the last 46 years.

It appears the top of one of the outer spindle shafts is 5/8" not 3/4", although I did not check it with a caliper.   There is a sticker on the trailing end of the deck that may offer some info but nothing I can decipher.
