Turn engine over until piston (6) of cylinder being removed
is at bottom of its stroke.
3.
Carefully raise cylinder just enough to permit placing clean
towel under piston to prevent any foreign matter from
falling into crankcase.
NOTE
If cylinder does not come loose, tap lightly with rawhide or
plastic hammer perpendicular to cylinder fins. Never try to pry
cylinder up.
4.
Carefully lift cylinder over piston and cylinder studs (8).
Do not allow piston to fall against cylinder studs.
NOTE
To avoid damage to piston assembly and/or cylinder studs, do
not allow piston to fall against studs.
5.
Discard cylinder base gasket (9).
NOTE
With cylinder removed, be careful not to bend the cylinder
studs. The slightest bend could cause a stress riser and could
lead to stud failure.
6.
Install a 6.0 in. (150 mm) length of 1/2 in. (12.7 mm) I.D.
plastic or rubber hose over each cylinder stud. This will
protect the studs and the pistons.
Handle piston with extreme care. The alloy used in these
pistons is very hard. Any scratches, gouges or other marks
in the pistons could score the cylinder during engine
operation and cause engine damage. (00546b)
Wear safety glasses or goggles when removing or
installing piston pin retaining rings. Piston pin retaining
rings are compressed in the ring groove and can fly out
when removed from the groove, which could result in
serious eye injury. (00293a)
7.
See
. Remove piston pin lock ring as follows:
a.
I n s e r t P I S TO N P I N L O C K R I N G
REMOVER/INSTALLER (Part No. HD-34623-C) into
piston pin bore until claw on tool is positioned in slot
of piston (directly under lock ring).
b.
Squeeze handles of tool together and pull from bore.
Hold a shop towel over bore during removal in the
event that the lock ring should fly out. Remove lock
ring from claw and discard.
NOTES
•
It is not necessary to remove both piston pin lock rings
during piston removal. Leave second lock ring in piston
pin bore.
•
Do not reuse piston pin lock rings. Removal may weaken
lock rings and they may break or dislodge if reused, res-
ulting in engine damage.
•
See
. Piston pin has tapered ends to help seat
the round lock rings.

NOTE
To avoid damage to piston or cylinder base studs, use PISTON
SUPPORT PLATE (Part No. HD-42322) to secure piston in
place while removing piston pin.
8.
Remove piston pin. Since pin is a loose fit in piston, pin
should easily slide out. If pin is difficult to remove, use
PISTON PIN REMOVER (Part No. HD-42320-A), as fol-
lows:
a.
. Remove acorn nut and spacer (1)
from rod end of tool.
b.
Slide rod end through piston pin. Install spacer and
acorn nut on end of rod.
c.
Position rubber coated tips (2) of tool on flat on each
side of piston pin bore.
d.
Hold tool body (3) and turn handle (4) clockwise until
piston pin is pulled free of bore.
9.
Remove piston from connecting rod. Be sure to hold con-
necting rod shank upright to prevent it from striking
crankcase.
10. Place a 3.0 in. (76.2 mm) length of 1.0 in. (25.4 mm) I.D.
foam-type water pipe insulation around each connecting
rod to prevent damage.
11. Mark each pin boss with either an "F" or an "R" to indicate
front or rear cylinder, respectively.

pointing toward the front of the engine.
2.
Install piston assembly over connecting rod.
3.
Install piston pin.
NOTE
You may wish to place clean shop towels over cylinder and
lifter bores prior to the next step, to prevent the piston pin lock
ring from falling into the crankcase.
4.
See
. Install new piston pin lock rings with the
PISTON PIN LOCK RING REMOVER/INSTALLER (Part
No. HD-34623-C). Make sure the ring groove is clean and
that the ring is fully seated in the groove with the gap away
from the slot at the bottom.
NOTE
Avoid damage to cylinder and piston. Always use new lock
ring. Make sure lock ring groove is clean and lock ring seats
firmly in groove. If it does not, discard the lock ring. Never install
a used lock ring or a new one if it has been installed and then
removed for any reason. A loosely installed ring will come out
of the piston groove and damage cylinder and piston beyond
repair.

NOTES
•
Push rod covers and lower cover retainers MUST be
installed prior to installing cylinder heads. If this has not
been done, see
3.16 TOP END OVERHAUL: ASSEMBLY,
Push Rods, Covers, and Retainers
•
Thoroughly clean and lubricate threads of cylinder head
screws before installation. Friction caused by dirt and
grime will result in a false torque indication.
1.
See
. Coat mating surfaces of cylinder base
studs (14) and head bolts (1 and 2) with parts cleaning
solution.
2.
Scrape old oil and any carbon deposits from threads by
using a back-and-forth motion, threading each head screw
onto its mating cylinder stud.
3.
Remove head bolts from studs. Wipe or blow dry thread
surfaces.
4.
Thoroughly clean and dry gasket surfaces of cylinder (12)
and cylinder head (8).
NOTE
See
. The cylinder head gasket is unique for XR
models and has metal patches (2) that must be installed against
the cylinder head. When installing the gasket on the cylinder,
be sure the words "THIS SIDE UP" (1) and the metal patches
(2) are visible.
5.
Install a new head gasket to cylinder.
6.
Carefully lower cylinder head over studs and position on
dowels. Use great care so as not to disturb head gasket.
NOTE
Only oil film must remain on the cylinder head screw surfaces.
Too much oil will pool in the head screw sleeve preventing full
thread engagement.
7.
Lightly coat threads, underside of flange and bottom face
of cylinder head bolts in clean Harley-Davidson 20W50
engine oil. Wipe off excess oil.
8.
Start cylinder head bolts (1 and 2) onto cylinder studs, two
short bolts on left side of engine, two long bolts on right.
