RRJ-350 : Reluctor Ring Installation Tool
The patented Reluctor Ring Installation Tool is designed to fit Generation III engines, including the 4.8/LR4, 5.3,LM7 and 6.0/LQ4. It is designed to align GM #12559353 and #12586768 sensor rings on the crankshaft in the correct phased position. All steel construction. Now with an extended length to fit the extended flange on manual transmissions.
TECH TIP: Heat the reluctor ring to 450ºF (232ºC) then slide it onto the casting. Be sure to deburr all components before beginning assembly. Any sharp edges will cause the reluctor ring to catch on the casting, making assembly impossible.
