its hard to tell, we have two, im not sure the age of that one. i would estimate well over 5 years, damn near ten maybe
lets do the math;
40+ vehicle fleet
weekly torque checks 3 per wheel x 4 hubs = 12
52 weeks
24,960 torques yearly
now add in a LOW average of 40 torques per day for brake jobs, tires, and not to mention tail shafts, bearings, radius rods etc
14,240 maintenance torques ranging from 210 - 600
______
39,200
x 5 years
______
196,000 torques
/2 per wrench
______
98,000 torques estimated at 5 years service, and that wrench is DEFINITELY older than that. so a low low estimate
its good to 100,000-200,000
