How to loosen a tensioner on a car?

How to Loosen a Tensioner 1 Open the hood and locate the drive belt (s). Either locate the serpentine belt routing diagram in the engine compartment, or refer to the repair manual. 2 Determine the type of tension applied to the belt you’re replacing. 3 Locate the belt tensioner per belt routing diagram.

Which is the correct tension for a fractional rig?

For most fractional rigs the correct shroud tension is the same as that for a masthead rig, i.e., a tension setting that will keep the leeward shrouds from going slack. However there is one exception. On certain fractional rigs, the upper and lower shrouds lead to chainplates that are aft of the mast. The spreader is swept back.

How do you relieve tension on a pulley?

To relieve the tension, a tool is inserted onto the pulley or a square drive is provided to insert a tool or ratchet. Apply the correct tool the tensioner calls for, and turn the tool counterclockwise to loosen the tension.

What should the tension be on a boat?

There is a simple criterion for shroud tension. The initial rigging tension should be high enough that the leeward shrouds do not go slack when sailing close-hauled in a reasonably brisk breeze. The proper value for your boat can be found by a few trial runs under sail. Once the correct tension is known, the gauge can be used to maintain the value.

How do you remove a belt tensioner bracket?

Remove the other bracket bolts that hold the belt tensioner to the engine block. Use a ratchet and socket and turn the bracket bolts counterclockwise to loosen and remove the bolts from the belt tensioner bracket.

How can I loosen the tension on my alternator?

While holding the tool in place with the tension relieved, slip the belt off the most accessible pulley that you can reach. Loosen the two (or three) bolts on the alternator, on older vehicles that do not have an automatic belt tensioner.

Where is the hole in a belt tensioner?

Some belt tensioners have a 3/8-inch square hole in the end of the spring-loaded arm that can also be used to relieve the tension from the belt. Rotate the pulley on the belt tensioner counterclockwise to relieve the tension of the belt with the proper sized socket and ratchet. Slide the belt off of the belt tensioner pulley.

How do you loosen tension on a drive belt?

There are three ways to loosen tension on a drive belt, depending on the vehicle. The most common way in today’s vehicles is an automatic belt tensioner. This application is used on serpentine belts, which connect to every pulley of the engine. Older vehicles may have drive belts that were removed by pivoting an alternator to release tension.

Where can I find the belt tensioner diagram?

Often, if the belt routing diagram can be located, it will display if an automatic tensioner is being used. If you only have one belt connected to all of the pulleys of the vehicle, then you have an automatic belt tensioner. Locate the belt tensioner per belt routing diagram.

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 does a belt tensioner work on a belt?

Locate the belt tensioner per belt routing diagram. The automatic tensioner is a pulley on a pivoting bracket. To relieve the tension, a tool is inserted onto the pulley or a square drive is provided to insert a tool or ratchet. Apply the correct tool the tensioner calls for, and turn the tool counterclockwise to loosen the tension.
