Step 1)
Open your package and ensure you have all 12 parts:
2 Aluminum Brackets
1 Black Pulley
1 Pulley Spacer
1 Square Pulley Bolt
6 Alan head bolts (3 different sizes)
1 Set screw (you remove this after install is finished)
|
 |
Step 2)
Put the brackets together. Use all three screws to
hold them together, do not over tighten as it's
aluminum. Use of a thread locker is ok.
|
 |
Step 3)
Put the pulley spacer against the back of the
bearing (side where you see the whole bearing) with the
small side of the spacer on the bearing.
|
 |
Step 4)
Put the square bolt in the slider area of the bracket
and put it against the spacer
|
 |
Step 5)
Put the longest alan bolt through the front of the
pulley and lightly tighten it up but leave it loose
enough so that it will slide
|
 |
Step 6)
Same just another pic.
|
 |
Step 7)
Screw in the set screw so its up against the square
bolt. If your unit looks like this your set.
|
 |
Step 8)
This is where you will be installing it
|
 |
Step9)
Use the last two remaining screws to tighten the bracket
to your block with the pulley facing the timing belt,
obviously. Tighten it down, don't strip it and use of
thread locker here is also ok.
|
 |
Step 10)
Tighten in the set screw so the pulley is snug against
the belt. It will be set properly when you notice it
taking up the slack. You need only take up a small
amount of slack, too much tension will not help and
cause wear on the belt or pulley.
|
 |
Step 11)
Finally tighten down the pulley now that it's in the
correct position. Remember you left this bolt loose
during the assembly process.
|
 |
Step 12)
Here is how it should look now. Notice the pulley
only pressing slightly on the belt. This is all you
need.
|
 |
Step 13) Another pic. REMEMBER TO REMOVE THE
SET SCREW (still shown in this pic) as it will
eventually fall out! Once you tighten down the pulley
it's not needed, but keep it for future if you need to
re-tension the belt.
