a. See Figure 2. To properly locate the thrust washer (2), install the O-ring (3) in the grinding relief groove on the splined end of the rear camshaft between the machined area and the secondary cam sprocket. Do not stretch or break the O-ring as the O-ring is not sold separately, and damage will require purchase of a new Rear Cam Roller Bearing Kit.
b. Slide the thrust washer down the rear camshaft until centered over the O-ring in the grinding relief groove.
c. Slide the bearing inner race (1) down the rear camshaft until contact is made with the shoulder of the machined area.
d. Install the primary cam sprocket spacer (4) and sprocket on the camshaft, and secure using the thicker flat washer (6) and long flange bolt (5) from the Drive Gear Retention Kit (Part No. 25533-99A, purchased separately).
e. Wrap a clean shop rag around the camshaft to get a firm grip and also to protect your hand from the sharp edges of the sprocket. Tighten the flange bolt until the bearing inner race makes firm contact with the thrust washer (2).
f. Verify that the thrust washer is locked in place and cannot be rotated. If necessary, install the shaft in a vise using brass jaw inserts, and further tighten the flange bolt until the desired result is achieved.
g. Remove the flange bolt, 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.
Bearings may be a press-to-loose fit. If necessary, clean the OD of the bearing and apply Loctite 243 - Blue before installation. Use caution to avoid getting compound on the rollers or bearing ID.
3. For 1999 Touring and Dyna models only: Install the Cam Support Plate Oil Control Kit (Part No. 94667-00, purchased separately) into the billet cam support plate, after verifying the crankcase version, per instructions included in THAT kit.
4. See Figure 1. Install the new front cam ball bearing (6) and rear cam roller bearing (1) into the cam support plate as follows:
a. See Figure 3. Get the SCREAMIN' EAGLE CAMSHAFT/ CAMSHAFT BEARING REMOVER/ INSTALLER (Part No. 94085-09).
b. With the secondary cam chain side facing up, place the cam support plate on the support block (1) so that the outer races of the 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 the new bearing over the bearing bore with the lettered side up. Slide the pilot shaft of the bearing driver (3) through the bearing into the hole of the support block.
d. See Figure 4. Center the bearing driver (1) under the ram of the arbor press. Press on the driver until bearing (2) makes firm contact with the counterbore in the cam support plate (3).
e. Repeat the procedure to install the second bearing.
5. Apply Loctite 243 - Blue to the threads of the four bearing retainer plate screws. Fasten the bearing retainer plate to the cam support plate. Tighten the screws in a crosswise pattern to 2.3–3.4 N·m (20–30 in-lbs).

3Punch marks
Figure 5. Align Punch Marks on Teeth of Camshaft Sprockets
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.
11. Place the cup of the camshaft driver ( Figure 3 , Item 2) over the end of the front camshaft only.
NOTICE
During press procedure, keep tensioner shoe clear of chain to prevent damage to tensioner assembly. (00474b)
12. Center the end of the front camshaft under the ram, then slowly apply pressure to the driver to just 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 the 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 make sure that the assembly remains square and the inner race moves to the installed position in the roller bearing.
15. Refer to the 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.
17. See Figure 6. Be sure the primary and secondary cam chain tensioners are assembled as shown. If assembled incorrectly, the tensioners will not function properly. Install the secondary cam chain tensioner. Tighten the fasteners to 10.2–13.6 N·m (90–120 in-lbs). Remove the locking clip from the tensioner.
NOTE
Replace the original cam plate to crankcase O-ring with the new O-ring (Part No. 11301) from the Cam Service Kit (Part No. 17045-99D, purchased separately).
