Doesn't fit Vortec Truck!

By

About Me Auto Enthusiast, Truck Enthusiast

Comments about CARQUEST HP Set Double Roller 250:

Cranshaft Reluctor Ring is too swallow for thicker double roller timing chain. You will be better off getting a single roller or stock. Did test mock based on another users review and reluctor was making contact with chain in two separate areas. Pins on chain made contact on larger diameter ring surface and chain was hitting chamfered locating surface at sprocket. Depth of reluctor ring is 3.3mm and chain extends 3.7mm about .016" of contact between chain and reluctor. Need a .025" Thick arbor shim ID 1.25" X OD 1.750" to possibly avoid contact. Too much thicker shim may change pulley alignment and causing problems.

Wrong chain

By 

from USA

Comments about CARQUEST HP Set Double Roller 250:

This chain is indicated as an OEM replacement, but it doesn't fit under the timing chain cover. It's approx 1/10" too thick.

Check your application *very* carefully. Don't trust the description.

      warning the timing set will not fit if you have a timing reluctor .The timing reluctor will rub the timing chain and the metal chips will fall into your oil pan .The engine will need to be replaced shortly after installing.The words exact fit are not true .The timing gear caused my engine to go bad and nobody wants to step up and take care of what happend .
