Merc Bearings x ref
 

I asked this question some time a go and nobody answered. I tore one apart and here is what I saw:

Input gear set: Merc 31-86763a2 $137.75
Timken 383a $10.59
and Timken 28621 $16.64

Upperhousing roller (2): Merc 31-87156 $11.75
Torrington b168 $2.28

Lower propershaft: Merc 31-86752a1 $42.80
Timken m802011 $5.17

Drive shaft: Merc 31-86748a1 $33.90
Timken m802011 $5.17

Drive shaft: Merc 31-86754t $44.80
Torrington DD-51417 (no match found)

Upper gear set bearing (interior to the gear), must buy gear.
Torrington b3216 $8.09

Looking for:
1. thrust bearing part numbers
2. 3199328a1

If not next week I will prees out the two other drive shaft bearings and take the thrust bearings to the local shop.

Great information--what drive--hopefully TRS

Bravo...sorry.

I have some old TRS drives that I can probably pull the # from.
