    Kit 465MR-1, master rebuild, SM465 transmissions, 1968-1987 versions

    465MR-1;465MR-2

    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:

    Quality you can count on.

    Our master rebuild kits have been assembled for our customer's rebuilds as well as the thousands of rebuilds we do at Novak. It is the most complete kit we've seen anywhere and features all the consumable and wear item components. Cut-rate "BK" basic kits seen on the market don't hold a candle to the Novak kits' quality and completeness.

    These rebuild kits set the industry standard for reliability, using only premium bearings and seals from proven manufacturers like Timken, JTEKT, Nachi, CR Seals, and more. No single brand makes every part we require, so we hand-select each component to ensure unrivaled performance and longevity.

    Novak kits include:

    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.
