alternator belt

I'll rephrase my question. When belt is in the V of the pulley does back of belt sit level/above pulley or below pulley sides? Backside of belt below pulley sides indicates worn out pulley's thus belt won't be tight enough. If bottom of pulley V is shiny that a dead give away that belt is riding too far down in pulley & belt is slipping in pulley.

The substitution number is actually 1/2" longer than the original T20334 belt. Original belt is 48" long and R97758 is 48.504". According to Deere, the original is still available but it is only stocked in Germany. Should still be able to get it, but will take a while to ship. Ask your parts person to override the substitution and order the original number. Or you could source a 48" belt from auto parts store possibly. Width is listed as .688" and thickness at .406".

May I ask how you looked up the spec's for T20334? I understand if one enters part # in JD parts shopping cart then left click on part # in cart that part spec's can be viewed on some selected parts.
Thanks,Jim

I wonder too. It seems more and more parts no longer have specs listed other than weight.

The dealer access includes a system called Parts Expert. It has more specs listed than system available to public. Many times if part is obsolete, the spec is wiped out from dealer view also. Since the T20334 is still available from European warehouse, the spec is still listed luckily.
