If you have questions about fitment please contact Balmar before ordering. Balmar 1.360.435.6100
Pulley Bolts: The bolts supplied with these kits are representative of the particular engine the kit was modeled off of. These supplied bolts are not guaranteed to fit your particular engine.
Engine manufacturers often change bore depth and this is beyond the
control of Balmar. The bolts in the kit can potentially be either too
long or too short. It is up to the purchaser to ensure the correct
length bolts are used to hold the crank and waterpump pulleys.
Some pulley kits may include black anodized pulleys or a mix of black
and blue pulleys. On slower moving engine kits the turnover can mean,
that despite changing to blue many years ago, some black pulleys are
still in inventory. This is considered normal.
Belt Length: Balmar
tries very hard to supply the correct belts but variations in
alternator brackets, even on the same engine models, mean the belts in
the supplied kit may not be the correct length. Balmar will swap
them out if this is the case but you will need to supply us with an
accurate measurement and return the supplied belts to Balmar.
While many of these kits will "drop-in" without too much fussing, this
is not always a guarantee and some alignment may be necessary. Again
slight engine variations mean a 100% perfect drop-in fit is not always
The Pulley Kit:
These pattented AltMount / Balmar serpentine pulley
kits can drive an amazing amount of alternator horsepower. They utilize a
J-10 belt design with ten ribs yielding tremendous grip with minimal to no belt dust..
These kits are specifically designed to fit select Westerbek engine
models and Balmar is growing the list every day. If you don't see your
engine listed please contact Balmar or myself at the email address
Marine alternator upgrades using a single 1/2" or 3/8"
drive belt are severely limited by the amount of power that can be
handled by the belt. When increasing alternator size, using a
serpentine belt considerably increases your total potential output and means
little to no belt dust. Another benefit is that less belt tension is
required to drive up to three times the HP. This means longer lasting
water-pump bearings as well.
The kit comes with a set of anodized 10 groove
pulleys which fit over the existing crankshaft pulley and a replacement
water pump pulley. An alternator pulley is also in the kit. Kits include
a J-10 serpentine belt, Loctite, Tef-Gel and a spare belt.
Alternators, regulators & temp sensors need to
be purchased separately. If you order an alternator package
from me, it will come with the appropriate pulley pre-installed on the alternator.
