NOTE

Figure 3-95

. Because of the larger diameter additional

gear (which meshes with the pinion gear) on the outboard end
of the rear intake (2) cam gear, the rear exhaust (1) and front
intake (3) cam gears must both be installed before the rear
intake cam gear is installed.

Lubricate all cams and all cam bushings in right crankcase
with clean Harley-Davidson 20W-50 engine oil.

See

Figure 3-95

. Rotate crankshaft until timing mark on

pinion gear (5) points exactly at centerline of rear intake

NOTE

See

Figure 3-95

. "V" marks on rear intake cam (2) are not used

for timing of Sportster model engines.

Install rear intake cam (2). As you install this cam, rotate
it so that the three timing marks (dots) line up exactly with
timing marks on the pinion gear, rear exhaust cam and
front intake cam.

Install front exhaust cam (4). As you install this cam, rotate
it so that its timing mark (a dot) lines up with timing mark
(dot) of front intake cam.

NOTE

Make sure all timing marks on cams just installed line up cor-
rectly, as shown in

Figure 3-95

. If necessary, remove a cam,

rotate it slightly, and re-install it. If timing marks are off even
one tooth, engine will not run correctly.

13. Check cam gear end play through tappet bores in right

crankcase, for each cam gear as follows:

Turn engine over until lobe of cam gear being checked
is pointing toward its respective tappet guide hole.

Using a flat blade screwdriver, gently pry cam gear
toward gearcase cover.

Using a feeler gauge, measure gap between bushing
(in crankcase) and cam gear shaft thrust face
(shoulder). This is cam gear end play.

Compare your cam gear end play measurements with
the

. Make repairs as required

if end gap is less than the minimum specified, or
greater than the maximum specified (Service Wear
