Do you need to reset a hydraulic tensioner?
Typically, a hydraulic tensioner needs to be “reset” and locked after removing it from the engine. Remove the lock only after the tensioner, pulley, or slipper, and timing belt or timing chain are installed and aligned.
When do you remove the lock on a tensioner pulley?
Remove the lock only after the tensioner, pulley, or slipper, and timing belt or timing chain are installed and aligned. The next time you work with a drive belt, timing belt, or timing chain, you’ll likely have to loosen a tensioner pulley to remove it.
How do you release the tension on a serpentine belt?
Release the tension in the serpentine belt by inserting the drive end of a 1/2-inch ratchet wrench into the square hole in the belt tensioner, which is mounted near the top of the engine. Turn the ratchet counterclockwise until the belt loosens. Continue to hold the ratchet while sliding the serpentine belt off of the nearest pulley to you.
How to release explosive tension from a come-along?
These describe using the spring release in the arm to speed the process. Wound up your come-along for the first time, the branch didn’t break, and you don’t know what you’re going to do next? Don’t panic! Excuse the misspeaks: Cable (not cord), Clockwise (not counterclockwise), PAWL (not Paul), Ratchet Wheel (not ratchet), Tension (not stress)!
How do you release tension on a come along?
Watch the video to see the following procedure in action. To release the tension, we start by just sliding the spring’s hook from the bottom of the slot to the top. That releases the drive-pawls and they can swing freely. That doesn’t yet release the cable’s tension, though.
How to release tension on a Harbor Freight come-along?
That clunk is the sound of the stop-pawl being pushed off of the ratchet, thus releasing the tension just a little. The cable will release one step of the ratchet. Keep doing this and every time you push the handle all the way and then relax it, it will loosen the cable one more step. Do this until the tension is mostly gone.
Why do you need to release tension on a ratchet wheel?
It needs to be released in order to release the cable tension but it’s not possible to use your thumb on the trigger to do it at this stage due to the pressures involved. The drive-pawl is what incrementally pulls the cable in. It also prevents the ratchet wheel from reversing as long as they are in tension. They also need to be released.
Typically, a hydraulic tensioner needs to be “reset” and locked after removing it from the engine. Remove the lock only after the tensioner, pulley, or slipper, and timing belt or timing chain are installed and aligned.
How does a variable hydraulic tensioner model work?
Variable hydraulic tensioner models allow the tensioning of several thread sizes or types of threads using one Hydraulic Load Cell. The variable hydraulic stud tensioner models also have side hydraulic ports, giving them the lowest installed height. The operator places the Bridge and Load Cell over the nut.
When to remove retaining pin from hydraulic tensioner?
The retaining pin should only be removed after the installation of all the components: new belt, pulley, lever, hydraulic actuator. The reason for this guideline is that, once installed, the hydraulic actuator is in a vertical position and there is no risk of mixing air into the oil.
Where does a hydraulic tensioner need to be stored?
Here are some main points to consider when dealing with hydraulic tensioners: Hydraulic actuators should be stored upright (visible part of the piston rod to the top) to prevent leakage and to avoid oil mixing with the air.
