Jackson Gear Drive

I contacted Summit Truck Style for a Geardrive for my 1990 4.3L
GM V6. I wanted it to sound like it was not a little 1300cc 4 banger
and have the advantage of very accurate timing at the same time.
Being that my motor has a factory roller cam, the only brand that
would fit was a Pete Jackson GearDrive. The roller cam has a smaller
mounting area so the other kits will not work and the setup does
not have an adjustable cam button as there is not room for it. It
came well packed, had very well written directions and is as easy
as installing a chain setup.I was quite surprised to see how bad
my chain was! I sure am happy I tore into this motor before it failed
on the trail.

On
my SUZUKI I can just pull the grill/rad support with a few bolts
and then the rad, so it's all open to work on in 15 mins or so.
|
|
|
Now
just pull off the belt only one on my vortech 4.3L and then remove
the fan.
|
 |
Next
is the water pump. After that, off comes the pulley then balancer.
Be sure to use the proper puller or it will separate ruining the
balancer. I like to put each of the parts bolts/nuts ect into plastic
bags, makes it easy to keep track of them and easy to find if the
project takes a few days or weeks/years ect.

 |
Now
take out all but the back 2 oil pan bolts, just loosen those and
the pan will drop enough to get the timing cover off and on with
ease.
|
 |
Now
pull off the old gears and chain, remove the 2 bolts holding the
cam retainer and replace with the low profile ones supplied, use
some locktight! Install cam gear and torque to spec, bend over the
lockplate tabs and make sure to pound them as flat as possible so
they won't rub on the cover. Install the crank gear, line up the
marks and slide the idler gears on 1/2 way only. Now is when you
re-read the instructions provided. Push the cover with gasket onto
face of block, pull cover back off and check the clearance as per
the instructions. If correct then crank motor over by hand 2 full
times and check the movement of the reverse idler gear, see instructions
for how this is done, as it may vary depending on which kit you
have. Here is what it looks like installed.

Now just install
everything in the reverse order. I like to use the black RTV with
graphite in it, as it holds up well. Be sure to use a thin coat
not the fat beads, except on the bottom of the timing cover where
it meets the pan. I laid a medium bead there. Now this is the
"Quiet" gear drive but they are not silent, just not
as noisy. So expect some gear whine. I wanted a noisier one but
they are not made for the factory roller cam motor. After I took
it for a test drive, the throttle response was notably better!
That was a bonus I was not expecting! Thanks to Summit Truckstyle
my rig runs (and sounds) better.
