A-model Shortblock
Remanufacturing
WELL known for their crankshaft
remanufacturing, the Newton,
Wisconsin
based
Darkhorse
Crankworks division of Hoban Brothers
has now introduced an A-model
Shortblock Remanufacturing program.
Following Harley's decision to close its
own remanufacturing program last
year, Darkhorse has designed a
program for their dealers that
"provides an economical method" of
remanufacturing 2007 and later Harley
engines.
Darkhorse's General Manager John

Dahmer told AMD that "we know most
of our dealers currently provide cylinder
boring or valve/headwork for their
customers, and we don't want to
compete with them, so designed this
program to help make their dealership
more profitable.
"A dealer can send us a complete
lower end and we will manufacture it
back to better than new specs at very
attractive prices."
Darkhorse utilize their proprietary ProPlug system to "ensure that the
crankshaft stays truer, longer than any

OEM replacement crankshaft, and we
back that up with a two-year unlimited
mileage warranty.
"Our skilled craftsmen verify all
tolerances to meet or exceed all OEM
specs on the entire crankshaft and
crankcases, which provides the
strongest foundation for all stock-type
engine configurations."
For builds larger than the OEM 96" or
more powerful performance engine
configurations, Darkhorse offers
upgrades including proprietary
connecting rods, crankshaft balancing,
DHC engineered Timken bearing
upgrades and any other crankcase
modifications on request.
Dahmer went on to say that they sonicclean the crankcases and replace all
bearings with OEM or other upgrade
options. "It is the attention to detail
that results in value and durability. For

John Dahmer, General Manager,
seen here left: "We verify all
tolerances to meet or exceed all
OEM specs. The service is designed
to help our dealers make money, not
to compete with them."

example, main bearing races and
connecting rods will be replaced if out
of tolerance, and the crankshaft will be
assembled and trued within .0015" at
the main bearing races, using only
genuine Harley-Davidson main
bearings and OEM connecting rods."
