JW Bell O-rings
 
Bought a used TH200 with a JW Bell. What size O- ring do I need to mate the bell to the pump. Can't seem to find a part number.

Silicone around that area and on h the bolts works just fine. I only used the o rings the first time.

It uses the Pump Bolt sealing O-ring from a 700R4/4L60, The trade part number for it is 74309A. GM part number is 8654341, You will need 6 of them as they are sold each. PM me if you have any questions.

-011 is the size, 5/16 ID x 7/16 OD. Anyone who sells seals or bearings will have them.
