Installation Requirements
This kit also requires the separate purchase of Gasket kit, top overhaul (2007-later models) (17049-08) or (2004-2007 models) (17049-04A). These parts are available from a Harley-Davidson dealer.
This kit also requires the separate purchase of Cam gear cover gasket (25263-90D) which is available from a Harley-Davidson dealer.
All washers and fasteners used in the engine are hardened. They must not be mixed or replaced with unhardened parts. Do not reuse cover gasket.
Rider and passenger safety depend upon the correct installation of this kit. Use the appropriate service manual procedures. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00333b)
This instruction sheet references service manual information. A service manual for your model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.

Kit Contents
See Figure 2 and Table 3.
The kit is intended for High Performance applications only. This kit is not legal for sale or use on pollution controlled motor vehicles. This kit may reduce or void the limited vehicle warranty. Engine-related performance parts are intended FOR THE EXPERIENCED RIDER ONLY.
Check the engine for valve spring coil binding at full lift, valve to valve clearance and piston to valve clearance. Harley-Davidson recommends that this inspection or any subsequent piston modification is done by a Harley-Davidson dealer.
See the service manual for steps 1-8.
1. Remove main fuse.
2. Remove spark plugs.
3. Rotate the crankshaft so both valves are closed on the cylinder being worked on.
4. Remove rocker box covers. Remove and discard gaskets.
5. Remove the inner rocker housing assembly.
6. Remove pushrod covers, pushrods, tappet guides and tappets.
7. Remove gear cover screws. Remove gear cover. Remove and discard gear cover gasket.
8. Mark or note all the position valve train components. Valve train components must be reinstalled in their original positions during reassembly.
The pinion gear, oil pump gear or oil pump do not need removal.
9. See Figure 1. Rotate engine to align timing marks. Cams are numbered 1-4 from the rear exhaust (1) to the front exhaust (4). Remove camshaft (2). One at a time, remove camshafts (1), (3), and (4) and replace with the appropriate camshaft from this kit. Be careful to maintain timing mark alignment. Install camshaft (2) from this kit last. Carefully check alignment of all timing marks.
See the service manual for the following steps:
10. Assemble gear cover.
a. Check that specified camshaft play is present.
b. After final assembly tighten screws.
Torque: 9–12 N·m (80–110 in-lbs) Screws
11. Install the tappet guide and tappets using the new O-rings. Verify that tappets are fully oiled.
When installing non-stock cams, piston-to-valve clearance must be checked.
12. Place modeling clay, about 1/8 in thick, on piston valve reliefs (in areas where valve would contact pistons).
13. See the service manual for steps 10-11.
14. Install cylinder heads using old gaskets.
15. Temporarily tighten cylinder head screws.
Torque: 9.5 N·m (7 ft-lbs) Cylinder head screws
Wait ten minutes before turning engine after installing pushrods. This wait allows tappets to bleed down and prevents bending pushrods or valves.
16. Temporarily install inner rocker housing assembly using old gaskets.
17. Check pushrod length. Install pushrods. Allow tappets to bleed down.
18. Rotate engine so both valves on the front cylinder are partially open. Shine a light through the exhaust port. Look through the spark plug opening. If necessary, rotate engine to the point where the exhaust and intake valves heads cross.
19. Check the clearance between the exhaust and intake valve heads. Use a 0.040 in (0.102 cm) wire gauge to make this measurement.
20. Repeat previous inner rocker housing assembly steps for second cylinder.
21. Check pushrod length. Install pushrods. Allow tappets to bleed down.
If insufficient clearance exists, grind the valve seats deeper into the head to obtain the 0.040 in (0.101 cm) clearance between the valve heads. Do not reduce the valve margin to less than 0.031 in (0.089 cm) on 1200 cc engines. After grinding valve seats, assemble engine and repeat steps 10. and 16. Recheck valve head clearance.
22. Rotate engine through two complete revolutions by hand. Remove cylinder heads and measure clay at its thinnest point. If the clay is not at least 0.080 in (0.203 cm) thick, grind the valve seated deeper into the head, or cut notches into the piston crown to obtain that dimension. The depth of the notches must not exceed 0.135 in (0.343 cm).
23. Once all measurements are made, install cylinder heads using new gaskets, following Service Manual procedures, for cylinder head assembly torque sequence.
24. Assemble the inner rocker housing assembly, following Service Manual procedures for rocker housing assembly torque sequence.
25. Install rocker boxes using new gaskets from gasket kit. Consult the Service Manual for proper torque specifications.
26. See the service manual. Install main fuse.
To obtain maximum engine output available with installation of this Screamin' Eagle Cam Kit, Harley-Davidson recommends carburetor, air cleaner, exhaust system and ignition module changes. See your Harley-Davidson dealer.
