How does chain tensioner work?
Belt and chain tensioners reduce belt or chain slack and transmit drive torque uniformly. They also reduce noise and vibration; decrease sprocket, pulley, belt, and chain wear; and increase the life of drive components. Spring-loaded tensioners automatically maintain tension as belts or chains wear and stretch.
Why do I need to replace my timing chain tensioner?
The timing chain tensioner is responsible for keeping the proper tension on you timing chains. It does this by keeping constant pressure on the guide rail. If you are starting to get chain noises from the engine, especially on cold start ups you should inspect or replace the tensioner right away.
When to install chain tensioner on Hughes Engine?
As a fix to this problem, Chrysler issued technical service bulletin (TSB) #9-07-97 for the 1990-1997 V6 engines. The TSB required the dealership technicians to verify if chain/lifter noise existed, and if present, they were instructed to install a timing chain tensioner.
Can a chain tensioner be installed on a V8 engine?
The TSB required the dealership technicians to verify if chain/lifter noise existed, and if present, they were instructed to install a timing chain tensioner. It did not take long for Mopar devotees to begin installing these on the LA/Magnum V8 engines they rebuilt.
What kind of timing chain do I Need?
According to Melling, most of its timing chain sets have three keyways to ensure accurate timing for early or late-model vehicles, compatible for use with either performance or stock cams, and allow you to set the cam timing to stock, 4 degrees advanced, or 4 degrees retarded.
Is a chain tensioner really necessary?
A pulley chain tensioner is necessary when the frame has vertical dropouts because they stop the wheel from moving forward and back. In consequence, one cannot control the tension of the chain without a derailleur or a chain tensioner. But if the frame has horizontal or semi-horizontal dropouts a pulley chain tensioner becomes unnecessary.
What is the timing change tensioner?
The timing chain tensioner is a part that requires a lot of work to change . That’s caused by the necessary time to reach the tensioner and to synchronize the chain, which is in the engine, not as a belt that is external.
How does a cam chain tensioner work?
How it works. The purpose of the tensioner is to take up the slack on the cam chain as it stretches with normal use. It’s designed to only move in one direction. Springs push on a pushrod, which pushes on the cam chain guide.
What is a timing chain kit?
A timing chain kit is a selection of parts that link the movement between the engine crankshaft and camshaft. A basic timing chain kit will include the timing chains (metal links), camshaft and crankshaft sprockets, tensioners, guide rails, and necessary gaskets and seals.
