S&S Cycle Chain Drive Camshaft Set for Harley-Davidson Twin Cam 88 Engines - Manual (Page 5)

13. Support cam support plate on table of hydraulic press.
Using camshaft remover/installer tool H-D ® #43644,
remove stock cams and bearings from plate. Mark
chain with magic marker to indicate direction of travel.
See Picture 7.
Do not attempt to remove cams from bearings while bearings
are in bearing plate. Cams and bearings must be removed
from plate together. See Picture 7.
Cam and bearings may press out easily. Use care to support
cams so they don’t unexpectedly fall to the floor.
NOTES
●
Bearings are usually damaged during removal and should
not be reused. If S&S
® Cam Installation Support Kit is not
used, new cam bearings should be obtained from other
source and installed with new cams.
● Check primary and secondary cam shoes for wear and/or
damage. Do not re-use either shoe if more than
1 ⁄
2
the shoe
thickness is worn, or if there is any evidence of melting,
burning or cracking.
● Replacement shoes are installed per appropriate Harley-
Davidson
® service manual.
● If upgrading from keyed rear camshaft to splined rear
camshaft, further steps require use of 2000 and up splined
rear sprocket and spacer. Spacer style used with keyed cams
is not compatible with splined cams. Spacers are available
in five different thickness.
● Further steps require roller bearing and washers from S&S
installation kit 33-5175, or roller bearing kit H-D #8983. See
Figure 3.
● Do not remove the O-ring pre-installed on the nose of the
rear cam. It centers the original sprocket spacer.
● Do not use the O-ring provided in installation kit 33-5175.
It is included for use with original rear cams only, and it is
placed under the rear thrust washer.
● Do not use the .055” thrust washers in installation kit
33-5175. It is included for use with original cams only,
and is placed behind inner bearing race.
E. Installing New Cams and Reassembly
1. Test fit front and rear bearings into bearing bores. If
either bearing will slip into the bore, use red Loctite
®
271 on bearing outer race during installation. If either
bearing will not slip into bearing bore, use assembly
lube on bearing outer race during installation. Using
tool H-D #43644 and hydraulic press, install cam
bearings in support plate, roller bearing in rear location,
and ball bearing in front location. See Picture 8.
2. Using Loctite ® 243 (blue) on screw threads, reinstall
bearing retainer and tighten screws to 20-30 in-lbs.
3. Align cam timing marks and install secondary cam chain
in original direction of travel. See Picture 9.
