How does a spring tensioner pulley loosen a belt?
Push the pulley toward the other pulleys or accessories, loosening the belt. Spring tensioner pulleys, as the name implies, use a spring to hold tension on the belt. Most, if not all, spring tensioner pulleys are NAI tensioners and include a hydraulic damper.
How to find the tension in a pulley?
A train toy is made up of three carts of different masses connected by pieces of string. If string A is pulled with 7.05 N [right], find the tension in strings A, B, and C. 2. Two boxes (5.00 kg and 7.25 kg) are tied together by a rope and hang vertically from a frictionless pulley.
How does hydraulic damper work on tensioner pulleys?
The spring maintains tension, while the hydraulic damper keeps it from bouncing under load changes. This prevents timing belts and timing chains slapping and jumping teeth and keeps drive belts from slipping and making noise.
How do you reinstall a serpentine belt on an auto tensioner?
Reverse the procedure to reinstall the serpentine belt on the pulley system auto tensioner. Be careful to get the belt on the the other pulleys and aligned properly on all parts of the complicated routing, then apply the tool to allow the belt to be slipped onto the tensioner pulley.
What’s the hole in an auto tensioner pulley?
That hole is for a 3/8-inch ratchet nub, the part that holds the socket. Place the nub of the ratchet wrench into the square hole of the tensioner pulley and rotate the wrench. Try both directions, which will require you to flip the selector on the wrench to the opposite direction (so you can loosen or tighten).
Can a tensioner be replaced on a drive belt?
The bolt on the tensioner pulley is the one used to move the tensioner, to remove tension on the drive belt for removal. My plane is to replace the drive belt, the tensioner pulley, and the No. 1 and No. 2 idler pulleys.
What does the auto tensioner on a serpentine belt do?
The auto tensioner and its pulley is a spring-loaded device that keeps the serpentine belt tight. Its pulley is usually smooth while the other pulleys are grooved.
Where is the tensioner on a 2GR Fe?
The No. 2 idler pulley was smooth, while the tensioner was rough. The tensioner (p/n 16620-31040) for the 2GR-FE includes the pulley, the tensioner, and the bracket, which has five bolts which face the front. The bolts are behind the a/c compressor, which would have to be moved for clearance.
