REPAIR INSTRUCTIONS

Press seals into housings using smooth, even pressure to prevent cocking or distorting the seal. Gently press the seal into place. Correct installation depth is achieved as the driver tool bottoms against the positioning tool, as shown.

General Inspection

Any cracked transmission case should be replaced. Check all components for wear or damage. Replace all parts as required. Replace all gaskets, O-rings and any part that shows mutilation or damage. Repair all stripped threads, using a thread repair insert that is compatible with patch-lock type capscrews.

General Reassembly Instructions

Refer to “TRANSMISSION SPECIFICATIONS” on page 224 for torque specifications and for fits and limits.

All working metal parts, especially the bearings, should be coated with fresh, clean, specified gear oil while the transmission is being reassembled. This ensures immediate lubrication and helps prevent parts seizure during start-up. (Refer to Recommended SAE Grade Gear Oil in “Transmission Specifications and Capacities” on page 237.)

When installing bearings, use proper bearing drivers. When pressing a bearing onto a shaft, apply force to the inner race of the bearing. When pressing a bearing into a housing (bearing cover), apply force only to the outer race. Do not apply force that is transmitted through the bearing rollers, balls or cage. Damage and premature bearing failure can result. Always apply even pressure to the bearing to prevent it from cocking or distorting during installation.

As moving parts are installed, check the parts frequently to see that they are moving freely.

The following procedure applies to all three reverse idler gears

1.Install a new bearing into the reverse idler gear. Press until flush with gear surface. The bearing must not protrude on either side of the gear surface.

Drawn cup needle bearings (reverse idler gear bearings) have a specific direction that they must be installed. The radius end of the bearing is to be installed first. The flat end (the end with identification markings) faces against the angled shoulder of the pressing tool.

The following procedure applies to all three rear countershaft bearing covers.

1.Press a new bearing cup into the cover, using a suitable driver.
