Wear limit gauge 2”

Wear limit gauge 2”

Technical Specification

The JOST wear limit gauge may be a valuable tool for you. 
The lock on JOST fifth wheel couplings is adjusted at the factory to provide initial horizontal play of approx. 0.3 mm in the direction of travel with a new king pin.

This longitudinal play may increase to 2 mm as a result of wear on the lock jaw or wearing ring.
2” fifth wheel couplings (Class G 50) from JOST offer infinite adjustment to compensate for wear in the coupling lock. Only when this adjustment distance has been exhausted does the fifth wheel coupling need to be repaired. The JOST wear limit gauge makes it possible to determine whether the lock on a 2” JOST fifth wheel coupling or a 2” king pin has reached or exceeded the permitted wearing limit while the coupling is disconnected and closed.



Order No.: J 1027





Further instructions for testing when coupled are given in the JOST instructions for fifth wheel couplings.
