Piston Jets Installation
NOTES
• If piston jet is being reused, apply LOCTITE THREAD-
LOCKER 222 (purple) to threads of TORX screws before
installation.
• O-rings that are missing, distorted, pinched or otherwise
damaged will result in either oil leakage or low oil pressure.
Use of the wrong o-ring will have the same results. Since
many o-rings are similar in size and appearance, always
use new o-rings keeping them packaged until use to avoid
confusion.
1. See Figure 3-132. Apply a very thin film of clean H-D
20W50 engine oil to new o-ring (3) for piston jet. Install
new o-ring in groove of jet mounting flange.
2. With jet pointed upward, start two T20 TORX screws (1)
to secure piston jet (2) to crankcase.Tighten to 25-35 in-
lbs (2.8-3.9 Nm).
