| All XL Transmission assemblies are bench tested for
positive gear engagement and disengagement but it is always best for
a final check after unpacking transmission before being installed. |
All V-Twin Transmissions are assembled with late style
shifter cam plate that uses welded in pin for neutral switch indicator.
On some early (Pre 1974) case this pin may have to be shortened or
removed to allow cam plate to move freely. Failure to check this will
cause transmission to not completely shift through all gears. This
should be checked first prior to
assembly. |
| Gear Engagement Check |
Rotate pawl carrier (EE) until pawl carrier
contacts lifter arm (Y+X). Hold the shifter cam(D) with opposite hand
to prevent cam follower (I) from completing gearshifts. If hand pressure
is released from shifter cam the gears will be drawn into complete
engagement and all inspection procedures will be performed incorrectly.
Shift transmission into first gear then check gear to dog Pocket Engagement.
Correct
engagement should be 25%.
Shift transmission into all other gears checking Pocket Engagement,
which must be at least 50%.
Filing of lifter arms (Y+X) will produce changes in Pocket Engagement.

Installation |
Establishing Mainshaft
and Countershaft Endplay |
| Use the thinnest low gear washer and mainshaft washer.
On 1954-early 84 models the mainshaft thrustwasher must be installed
with Tang Down. For 1954-early 1984 models the mainshaft needle bearing
will have to be installed. Temporarily install access cover to crankcase
with all transmission parts. Carefully align Cover Dowel Pins and
with a rawhide mallet tap into position and install four cap screws |
When installing transmission into case check shift fork
shaft for correct alignment to case. Do not force transmission into
case if shift fork shaft will not go in to case. If shift fork shaft
is forced into case damage or bending to shaft will happen causing
shifter roller finger to bind against shifter cam plate or shifter
fork binging on shaft or with pawl carrier
assembly. |
On 1954-E84 Models Inspect case race
and rollers, if badly pitted scorred or worn they should be replaced.
Correct fit of main bearing is .0006in-.0014in. If clearance is beyond
specified limit a new race and bearings must be installed, and line
lapped for proper fit. Note: Fitment of door to case
may sometimes requires reaming of holes in access door or removal
of alignment pins from case. If removal of dowel pins is necessary
tapping
dowel pin holes and use of additional bolts is suggested. |
| Note also that even during factory assembly process
several access doors were tried before final assembly. |
| Using a Dial Indicator measure mainshaft endplay from
sprocket side of shaft, press against clutch gear so that bearing
seats against lock ring in access cover. Move shaft back and forth
and measure endplay while holding clutch gear in. If endplay is not
with specification (see chart) install thrust washer of suitable size. |
| With access cover still in place bend a discarded spoke
or other suitable wire and wedge into hole on end of countershaft.
Push and pull countershaft and measure endplay with dial indicator.
If endplay is not within specification (see chart) install countershaft
washer of suitable size. |
| After countershaft endplay has been established install
oiler plug in access cover with oil hole up. |
| Note: On 1959-early 84 models the clutch must be temporarily
installed and the 1984-85 models the Stator spacing ring and the Stator
must be installed on access door before above End Play clearances
can be established. |
When Mainshaft and Countershaft end play established
install new shifter shaft into the crankcase so that the shifter lever
arm is centered. Using a grease pencil mark the shaft at the 12 o’clock
position by marking the shaft you can tell if the shifter lever arm
position changes when installing the transmission. Correct shaft to
shifter pawl yoke engagement
is important for proper gear shifting. Install transmission and rotate
countershaft slowly to check that ghe gear shift arm is engaged with
shifter pawl. To do so rotate shift lever, a noticeable resistance
to movement indicates proper engagement. |
