Specs At A Glance

Good To Know

Q: Does this tool install the seal or remove it? A: It is a seal driver, so it presses the new front output seal into place; use a seal puller to take the old one out.

Q: Will one tool cover both the front and rear output seals? A: No, this driver is sized for the front output position on the NP246, so check the seal diameter before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
