INSTALLATION
NOTE
See Figure 2. If not enough of the splined shaft is exposed to install the sprocket, omit the spacer (4) and proceed to Step 2e. When the bearing inner race is started onto the machined area, remove the flange bolt (5), flat washer (6) and sprocket, then re-assemble using the spacer (4). Repeat Step 2e to fully install bearing inner race.
1. See Figure 2. Obtain new Rear Cam Roller Bearing Kit (8983) from Cam Service Kit (17045-99C) and install according to the following:
NOTICE
To center thrust washer, be sure O-ring is installed in relief groove. Damage to bearing cage and engine can occur if thrust washer is not centered. (00473d)
2. See Figure 2. Install O-ring, thrust washer and bearing inner race onto rear camshaft as follows:
a. To properly locate thrust washer, install O-ring (3) in grinding relief groove on the splined end between the machined area and the secondary cam sprocket. Do not stretch or break O-ring since the O-ring is not sold separately and damage will require purchase of new roller bearing kit.
b. Slide thrust washer (2) down rear camshaft until centered over O-ring in grinding relief position.
c. Slide bearing inner race (1) down rear camshaft until contact is made with shoulder of machined area.
d. Install primary cam sprocket spacer (4) and sprocket on camshaft and secure using thicker flat washer (6) and long flange bolt (5).
e. See Figure 2. Wrap a shop rag around camshaft to get a firm grip and also to protect hand from sharp edges of sprocket. Tighten flange bolt (5) until the bearing inner race makes firm contact with the thrust washer (2).
f. Verify that thrust washer is locked in place and cannot be rotated. If necessary, install shaft in vise using brass jaw inserts, and further tighten flange bolt until the desired result is achieved.
g. Remove flange bolt, flat washer, sprocket and spacer.
NOTE
See Figure 1. The front and rear cam bearings are not interchangeable. The rear bearing is a roller bearing and the front bearing is a ball bearing.
NOTE
Bearings may be a press-to-loose fit. If necessary, clean bearing OD and apply Loctite® Threadlocker 243 - Blue (99642-97) before installation. Use caution to avoid getting compound on rollers or bearing ID.

3. For 1999 models only: Install Cam Support Plate Oil Control Kit into billet cam support plate, after verifying crankcase version, per instructions included in the Oil Control Kit.
4. See Figure 1. Install new front ball cam bearing (5) and rear cam roller bearing (1) into cam support plate according to the following:
a. See Figure 3. Obtain the CAMSHAFT/CAMSHAFT BEARING REMOVER/INSTALLER (HD-43644).
b. With the secondary cam chain side facing up, place cam support plate on support block (1), so that outer races of bearings are properly supported. Note that one corner of the support block is contoured to accommodate the chain guide blocks cast into the front of the support plate.
c. Center new bearing over bearing bore with the lettered side up. Slide pilot shaft of bearing driver (3) through bearing into hole of support block.
d. See Figure 4. Center bearing driver (1) under ram of arbor press. Press on driver until bearing (2) makes firm contact with counterbore in cam support plate (3).
e. Repeat procedure to install second bearing.
5. Apply Loctite Threadlocker 243 - Blue (99642-97) to threads of four bearing retainer plate screws. Fasten bearing retainer plate to the cam-support plate. Tighten the screws to 2.3–3.4 N·m (20–30 in-lbs) in a crosswise pattern. Verify that the hole in the retainer plate is properly aligned with secondary cam chain oiler (except 2005 and later models).
6. Place the cam support plate back on the support block, if removed. The block supports inner races of bearings as camshafts are installed.
7. See Figure 5. Align punch marks on teeth of secondary cam sprockets (outboard faces). Use a colored marker to carefully mark the punch-mark locations on the inboard side of the sprocket teeth. These marks help align the camshafts when they are pressed into the bearings.

Figure 3. Camshaft and Camshaft Bearing Remover/Installer (part number HD-43644)
8. Place the secondary cam chain around the sprockets of both the front and rear camshafts. To maintain the original direction of rotation, the colored marks on the chain link during disassembly must face opposite the cam support plate during installation.
9. Position the camshafts on opposite ends of the chain, then verify that the colored marks placed on the inboard side of the sprocket teeth are aligned.
NOTE
Do not mix camshafts during the press procedure. The rear camshaft, which can be identified by the splined shaft, must press into the roller bearing at the rear of the cam support plate.
10. Maintaining the position of the camshafts on the chain with the colored marks in alignment, place the sprocket ends of the camshafts into the bearings.

12. Center the end of the front camshaft under the ram, then slowly apply pressure to the driver just to start the front camshaft into the bearing ID.
NOTICE
Be sure rear camshaft is aligned during press procedure. Misalignment can cause inner race to catch on bearing rollers resulting in bearing damage. (00475b)
13. Slowly apply pressure to the driver on the front camshaft, while wiggling the rear camshaft as necessary to guide the inner race between bearing rollers.
14. When the inner race on the rear cam is started into the roller bearing, apply pressure to the driver until the front camshaft is fully seated. If necessary, keep finger pressure at the top of the rear camshaft to ensure that the assembly remains square and the inner race moves to the installed position in the roller bearing.
15. Refer to the applicable Service Manual and check for proper cam-to-cam timing using a straightedge along the punch marks.
16. Install the new retaining ring in the groove at the end of the front camshaft.
