"O" Ring Part # needed TD15B/175B

[Johnny Burnette]

Does anyone have a parts manual for the 15B's or 175B's?

I need the part number or specs for the large O ring (like 20 or 21 inches) that goes between the torque converter housing halves.

Have my engine ready to go back in with the exception of this O ring...it is a little stretched and I have spent WAY too much on this rebuild to even chance it.

My serial Number is L175BP 15129

Sorry, don't have the "B" parts manual, but the part # for the "C" is 321 988 R1. May be the same for both machines? Anyway, hope this helps you in some way.

Measure the diameter of the oring groove then the thickness of the old oring

As a follow up, the 175C O''ring #321 988 R1 measures ID 19.725" X OD 20.145" x .210" Dia.
