Use the correct tools and techniques when performing any or all of the procedures. sleeve, 61) Fork, Place third gear and its synchro ring on the mainshaft. Never use a dummy shaft to load needles. P represents the manufacturing plant, Muncie. Here is the result of our rebuild. These have a tendency to fly off the cover and get lost. %PDF-1.2 % The orientation of these parts is critical. 2. They are found primarily in GM and Chevrolet trucks, Blazers, Suburbans and many other models falling under the 1/4-ton to 1-1/2-ton platforms. shaft The workflow pattern is as follows: Disassemble the entire gearbox, inspect all components and parts, repair or replace all parts that are excessively worn or damaged, inspect all subassemblies, check subassembly fits and clearances, and then conduct the final assembly. Usually they end up in the bottom of the case. The midplate is preassembled with the rear bearing. Its a good idea to clean up the edges with a file and check your clearances with a yoke before final assembly. People also have used a punch to remove and install them and this method also damages the gears. The Muncie was used in all high performance applications until the Borg-Warner Second Design Super T-10 began replacing it in 1974. Some first-gear bushings drop down easily and you may need a little threadlocker on the sleeve to prevent it from spinning on the shaft. Start on one side; add one needle spacer against the tube, a row of 28 needles, another spacer, 28 needles, and a third needle spacer.
