GATES TRAINING: Micro-V Stretch Fit Belt Installation

GATES TRAINING: Micro-V Stretch Fit Belt Installation


Until recently, all automotive belt drives had
Two things in common: One of more belts had transfer engine power to
Various accessories, And a device to maintain the correct tension
On the belt. correct belt tension is critical for long
belt and bearing life, low-noise, and the efficient transmission of
power from the crankshaft. While belt tensioning systems are still critical
components on most cars, A new, self-tensioning V-Rib Belt technology was introduced to the OE market several years ago on some two to four-point drives. These self-tensioning belts do not need a separate tension device, in fact they’re designed to stretch slightly over the
pulleys during installation, and then automatically adjust to the correct tension needed for the application. Gates Micro-V Stretch-Fit Belts were designed to do just that. Gates has been manufacturing these patented Stretch-Fit Belts
for the OEM market for several years. Now, Gates is the first manufacturer to make self-tensioning belts available in the aftermarket. Here’s what you need to know about this new
belt
technology. Stretch-Fit Belts are made from highly engineered EPDM Elastomer, they have aramid fiber reinforcement, and a patented tensile cord. They look just like standard Micro-V belts but they’re not interchangeable. Because they’re designed to stretch slightly during installation, they are sized shorter than the standard V-Ribbed Belts. Stretch-Fit Belts require special installation tools available now from your Gates servicing supplier. Finally, if the vehicle has a self-tensioning belt on the
drive, it must be replaced with a self-tensioning belt. Of course, a good indication that a Stretch-Fit Belt is needed
is that the drive does not have the tensioner. Check your current catalog or your online parts look-up for the appropriate applications. Let’s take a look at the correct installation procedures of these new belts. Installation instructions are printed on the inside of each Stretch-Fit Belt sleeve. It is very important that the instructions are
followed correctly to avoid damaging the belt. Each application can have a slightly different set of instructions, s so be sure you look at the inside of the
sleeve each time you replace the Stretch-Fit Belt. Here are the installation instructions for the Ford Escape. Always start any installation by turning off the vehicle and
disconnecting the negative battery cable for safety reasons. Place a new Stretch-Fit Belt around the drive, making sure the
ribs are aligned in the pulley grooves properly. Put a zip-tie three millimeters in width through one of
the holes of the pulley around the belt. Pull the zip-tie snug, this will keep the belt in place. Next, rotate the crankshaft using a socket wrench
Until the belt slides easily on the pulley.
This
should only take about a half-turn before the
Belt slides easily on the pulley. This should only take about a half-turn before the
Belt slides easily on the pulley. Make sure the belt is aligned in the grooves of the pulley. To complete
the installation, cut the zip-tie off with a pair of side cutters. Remember that stretch with belts do not need tensioning,
the belt tensions itself on the drive. Reconnect the battery cable, and installation is complete. Here the installation instructions for Chevy CK series vehicles. Always start any installation by turning off the vehicle and
disconnecting the negative battery cable for safety reasons. The installation on the CK Series is slightly different than
most because the drive can have two V-Rib Belts. The outer accessory drive is what you’re familiar
with, as a regular tension V-Rib Belt The Stretch-Fit Belt is on the air-conditioning accessory drive. While you are replacing the Stretch-Fit Belt, this
is a good time replace both belts. Let’s now walk through the installation procedure. In order to get to the Stretch-Fit Belt, you’ll have
to remove the outer accessory drive belt. Begin by cutting off the old self-tensioning belt. Now place the new stretch-fit belt around the AC drive. Make sure the ribs are aligned in the pulley grooves properly. Next, place the Gates Stretch-Fit Mounting Tool against the crankshaft pulley,
with the lip over the outside edge of the pulley. If you do not have the mounting tool, do not use a screwdriver
or other tool to pry the belt on the drive. It will damage the belt and make the belt unusable. The mounting tool is available through your servicing
parts store as part number 91030. It is re-usable, so you do not have a re-purchase one for each installation. Now rotate the crankshaft as you guide the belt around the pulley by
allowing it to slide over the lip of the installation tool. Check to be sure the belt is aligned in the pulley grooves properly. Finish by installing the new standard accessory drive belt. Reconnect the battery cable, and installation is now complete. If you need further assistance with installation, you may call

  1. @ajhnson you have no choice if it came with a strech belt u have to use this belt. they dont come with Tensioners anymore. Pay more attention to the video next time.

  2. This is very general,, use care to make sure the belt tool clears everything on the back side of the pulley as you turn the crankshaft  and also make sure and remove the tool before restarting the motor.. these steps were not mentioned..

  3. How do you remove that strech belt if you had to replace alternator ? Do you have to cut it and buy another strech belt ?????

  4. Don't you just love when you're treated like an idiot?
    Why not explain how the new belt tightens?
    And why a used belt must be discarded?
    Didn't really show how the tool works, did they?
