This gage is used to determine crankshaft deflection during alternator installation on Evolution, and FDL, and Tier 4 engines. Simply attach the proper length mandrel onto the gage to correspond with the engine being serviced.
Directly below the gage is a counterweight so that when the gage is positioned between the webs, it will automatically face downward displaying the gage face. The kit comes complete in a compact storage box for added protection.
The dial indicator has .0001" gradations.
Replacement parts are available:
Tier 4 Mandrel for Nitrided Crankshaft
T81252-2D Tier 4 Mandrel for Induction Hardened Crankshaft
This kit and mandrels come with custom ground carbide points (T81252SP - Sharp Points) which thread into both the mandrel and opposing indicator stem, but can also be substituted for the rounded points (T81252T).
Caution: The dial indicator reads in .0001" increments and is very delicate. This must be treated as an precision instrument otherwise it will break.
