Chapter 2- Drive System: CVT and Transfer Case
NOTE: Seal installation tips:
• The sealing surface on the shaft should be
inspected before assembly. Small scratches on
the sealing surface can be polished-out.
• Protect the lip of the seal using a seal protector
sleeve, obsolete microfiche, plastic, or cello-
phane tape.
• Lubricating the seal lips will help prevent dam-
age.
• Do NOT use sealant between the seal and the
case.
• Drive seals straight down, by the outside edge,
using a suitable driver.
• Drive seals flush with the surface of the case
unless otherwise noted.
4q. Using a seal protector that spans the hog
ring groove, install the input shaft seal.
See Figure 2.144.

NOTE: The lip of the seal will invert if it passes
directly over the hog ring.
4r. Once the seal is fully seated, the hog ring
can be installed. It will be necessary to
make a special tool by modifying a lug nut
(P/N: 712-3050).
• Grind-down the peaks between each facet until
all the peak-to-peak measurements are less
than 3/4" (1.9cm). Smooth the transition from the
tapered seat of the lug nut to the facets.
4s. Fasten the lug nut to the input shaft using a
5/16"-18 bolt. The tapered side of the lug
nut should face away from the input shaft.
4t. Slip the new hog ring over the lug nut, and
press it down using the flat side of the
heavy spacer previously removed from
the input shaft. See Figure 2.145.

4u. Press the hog ring home to its groove
using the spacer.
4v. Once the hog ring is seated, reverse the
spacer so that the recessed side goes
over the hog ring. See Figure 2.146.

4w. Apply a small amount of thread locking
compound such as Loctite® 242 (blue) to
the four screws that hold the adaptor
housing to the case.
