Oil Line installation is crucial to engine life. If you are not sure
that you can properly perform this operation, please contact
the S&S
®
Tech Department for a referral to a shop in your area.
NOTE: Installation instructions are based on an engine and
transmission already in the chassis.
1-
Remove the stock oil supply and return fittings
from the transmission.
2-
Install two supplied
3
⁄

NPT pipe plugs (S&S PN 50-8330)
in the oil fitting location.
NOTE: Apply thread sealant to all tapered pipe threads.
3-
Drain the oil from the oil pan—see the proper
factory service manual for instructions—and then
remove the oil pan from the motorcycle.
4-
Place the supplied template (53-0080) over the oil
pan baffle and use a scribe to mark the location of
the
1
⁄
2
” hole as shown in Picture 8. Use a drill press to
machine the
1
⁄
2
” hole as marked in Picture 8a. Use a
small file or deburring tool to make sure no chips or
pieces are left on the
1
⁄
2
” hole and then clean the oil
pan and baffle with solvent before reinstalling the
pan with a new gasket on the motorcycle.

Remove the transmission top cover. Remove the
neutral indicator switch, vent line and fitting from
the transmission top cover.

fitting on the new S&S transmission top cover (S&S
PN 56-1615).

Slide the oil feed line (S&S PN 31-0442) through the
hole in the top cover closest to the oil filler/dipstick
boss. Place a new top cover gasket (S&S PN 56-1256)
on the transmission case and position the new S&S
top cover on it. Rotate the oil feed line so it will pass
through the
1

2
” hole in the baffle. Be sure the bend
in the oil feed line orientation is to the rear of the
motorcycle. See Picture 9.

Install the transmission top cover screws and
washers according to Detail A. Use blue
threadlock on the screws, but leave them loose at
this time.
