Jackson 999-210 Automobile Battery Charger User Manual


 
power steering bracket to attach your lower bracket
to, you will use special bracketry that we have
included with your kit. Turn to figure 3.4 in the
installation manual and find the note describing the
bolt that will be used for the non-power steering
car’s lower strap bracket anchor. The Mazda idler
pulley set-up for your 4-rib belt has a cast iron
bracket that is bolted to the engine block. This
bracket is held on by three large bolts. The lower
bolt of the triangle pattern will be the one you
attach our “L” bracket to. It is in the position noted
in figure 3.4. This is where you will attach the small
“L” bracket to the engine block using the new
Ml0x50 fine thread bolt we provide. The lower strap
bracket can then be attached to this “L” bracket,
supporting the outside of the supercharger. For the
belt drive, please remove all the adjustment hard-
ware from the cast iron Mazda idler bracket (the idler
pulley, the special mounting bolt, the vertical adjust-
ment bolt, etc.). You will be left with just the naked
iron bracket on the engine. Using the 2.5” diameter
idler we provide, and the Ml0x50 bolt, washer and
nyloc nut, mount the nylon idler to the front of the
Mazda cast iron bracket. Make sure to put the Mazda
Cast Iron washer under the bolt’s head and to aim the
bolt toward the radiator (see diagram). Run the belt
over the crank pulley the supercharger and around
the air conditioning compressor. Push the idler down-
ward and tighten its center bolt to properly tension the
4-rib belt. If you are careful, a screwdriver can be
placed in the cast iron Bracket’s vertical slot to lever
the pulley downward. This will help you get the proper
tension on the belt. You should have less than
3/8inch deflection on the longest run of the belt. If
you find the belt to fit too tightly, gently rock the car in
fourth gear while pressing the belt onto the pulley.
Watch out for your fingers. UNDER NO CIRCUM-
STANCES SHOULD YOU USE THE ENGINE
STARTER TO “BUMP” THE BELT ONTO THE
SUPERCHARGER. DOING SO PUTS A HIGH
LOAD ON THE SUPERCHARGER BEARING AND
WILL VOID YOUR WARRANTY. IT ALSO IS VERY
DANGEROUS. Loosen the pinch bolts on your relo-
cated power steering adjustment assembly (12mm
head on pillow block pinch bolt, 14mm head on
lower front bolt). Tighten the long bolt “D” per figure
3.4 to achieve correct belt tension. The longest run of
the belt should not deflect more than 3/8 of an inch
when pressed down with around 22 pounds of
thumb pressure. The tension specification is 90
pounds. Re-tighten the pillow block pinch bolt, idler
bracket bolt, and the power steering pivot bolt. An
easy check for proper belt tension is done by listen-
ing to your belts during warm up. If turning the steer-
ing wheel with the air conditioning on creates a
squeal, then the tension is far too loose. In general,
only a slight amount of black dust should appear
around the supercharger nose when the tension is
correct. Heavy dusting indicates excessive belt wear
from a loose belt. Check your tension again after the
first 500 miles - it will loosen slightly as the belt wears
in. NEVER ATTEMPT TO ADJUST THE BELT
WITH THE ENGINE RUNNING! Re-tighten all bolts
and double-check your work.
