Upgrade & Restore Your Tire Changer's Mechanical Rigidity

The Proguard Positioning Pin Extension / Anti Rotati is a high-tensile structural fastener designed to clamp and secure cylinder plates, tower bases, and mechanical brackets on professional tire changers.

Worn, stretched, or cross-threaded bolts cannot hold the proper clamping force, which leads to mechanical shift and misalignment. Replacing them restores rigid mechanical alignment.

📋 Factory Service Bulletin Guidance:

Update Date: May 2013
Subject: ProGuard – Positioning Pin Extensions

There are currently three different positioning pin extensions for the ProGuard. The standard equipment long silver pin shipped with the machine, 0.450” in shaft diameter, is P/N 83031335. The optional medium length silver pin is P/N 83032133. The optional long black pin, 0.550” in shaft diameter, is P/N 85607767. The long black pin is stronger than the long silver pin and is less prone to damage during use. (There may be a few wheels with stud-holes too small to fit the black pin.)
