Bolt Together Torque Converter Replacement O-Rings
All Neal Chance Bolt Together Converters use an O-ring to seal the two halves. If you need a replacement O-Ring, you can buy them from us direct, or if need be you can get these at an Auto Parts Store. We use the same seal as popular transmission front pump O-rings, so they are readily available. See chart below for applications.
Torque specs on the bolts around the converter are 17-20 ft. lbs. – Do Not Over Torque!! Make sure and use a star pattern for the first 8 bolts tightened.
