Alternator relocation is the third part of the
ProCharger installation on this 2018 Jeep JL.
What you’re looking at in this photo is the new
alternator bracket (left) and the stock alternator
bracket (right). The idler pulley on the factory
alternator bracket will be removed, saved, and
reinstalled on the kit’s main bracket later.
Main bracket assembly and installation is the
fourth part of this ProCharger Jeep JL applica-
tion. In this photo, you can see the idler pulley
from the factory alternator bracket has been
relocated to the passenger side of the new
main bracket. The driver-side idler pulley will
also be removed from the timing cover and
reinstalled on driver side of the main bracket.
This shot from below shows how the factory
alternator was relocated to a position near
the steering box. The crescent moon–shaped
alternator bracket is mounted to the timing
cover using kit-supplied hardware to replace
two factory timing cover bolts. A kit-supplied
stiffening brace was also added between the
far end of the bracket and a tapped hole on
the engine block using supplied hardware.
With both idler pulleys now attached to the
timing cover side of the main bracket, the
kit-supplied hardware (and one factory bolt
removed from the alternator) was used to
install the main bracket. The belt was then
threaded through the inside of the two idler
pulleys for the next step—the installation of
the ProCharger head unit.Fifth in the series of procedures is installing the
ProCharger head unit. The first of those steps
was to fill it with the 6-ounce bottle of super-
charger oil supplied with the kit. You will need to
burn up all the old fuel (or at least have no more
than a quarter tank) in your Jeep before running
this blower though; anything less than premium
(91 octane) gasoline can cause detonation.The ProCharger head unit has a dipstick so it
can be routinely checked for oil level. Accord-
ing to ProCharger, the head unit’s oil should
be completely changed for the first time at
500 miles, and then at 6,000-mile intervals
after that. The hex-head drain plug on the
underside of the head unit can be removed to
drain the oil.Nestled into the main bracket, the ProCharger
head unit was held in place until a couple of
its six kit-provided mounting bolts that come
in from the back of the bracket were finger-
tightened. Two of the six mounting bolts
(meant for the bottom of the head unit) are
hex-head, allowing easy tool access with an
open-end wrench. The top four of the six bolts
are socket head cap (Allen) style and can be
accessed with a ratcheting wrench. Once all
those were tight, a^1 ⁄ 2 -inch breaker bar was
used to pull the tensioner pulley toward the
driver side so the belt could be slipped over
the ProCharger head unit’s pulley.
