The SM465 is arguably one of the
greatest four-speed transmissions ever built, and reconditioning one is a worthwhile project.
The Kit
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is
the most complete kit we've seen anywhere and features all the consumable and wear item
components for both the main case and top cover shift rails.
Our kit standardizes the SM465 thrust washer and endplay and we recommend that you use the
supplied shaft bushings with the supplied thrust washer for simplicity.
There are two versions of our rebuild kit, each compatible with all 2wd, 4wd and conversion
465's:
The first and most common kit is for 1968-1987 versions. Next are the 1988-1991 versions
with the narrower .68" front bearing.
The last kit is for the 1988-1991 version - typically with the aluminum top cover - with the
wider .83" front bearing. The only way to know this version is to remove the front bearing
retainer and check for a #211 bearing or to remove it and measure its width.
Rebuild Requirements
It is common for our customers to do top-level rebuild work, using good methods and by following
our included instruction guide.
We suggest the rebuilder have access to a set of snap ring pliers, a bearing puller and a
hydraulic press.

This is the rigid PTO cover that every Novak-built transmission
gets, and we recommend them to our customers. They seal better and stay that way for
far longer than the stamped steel versions from the factory. Stainless button-head
fasteners are included.
Worn out shifter sticks or factory shifter sticks that are
wierdly bent for Jeeps or a stick that's missing altogether... Replace it with the
new, straight version that is a more appropriate length for a Jeep and ready to take
an industry standard knob.

Gaskets set, SM465 transmission, #WT304-55
This is the gasket kit to seal up your SM465. This is included
with our master rebuild kit, adjacent.
If purchasing the mainshaft version of the Novak adapter kit,
these bushings are required. Note that these also come in our master rebuild kit
(adjacent). If purchased at the same time as the adapter kit, we will press one of
the bushings on the mainshaft for you - the other two must be installed with your
gears due to sequencing.
The SM465 is pretty close to perfect in its design, but this
update to 3rd gear and its slider are considered to be essential. The tapered clutch
design prevents 3rd gear from kicking out under torque. This and other components
can be seen here.
This billet aluminum front bearing cap for your SM465
countershaft is far more rigid than the stamped steel, leakage-prone factory unit.
It comes with countersunk fasteners.
