New, Stronger " Drive Ratchet Available{0610}
Usage:
A new 5P7443 Ratchet is stronger than the former ratchet and is made with enough clearance to use either a gear with 20 teeth, or one with 30 teeth. The 5P7443 Ratchet has a 3/8" drive and is a direct replacement for the 8H8572 Ratchet.
The gear with 20 teeth is standard on the new 5P7443 Ratchet; however, two repair kits are available for parts service. See the chart which follows:
