Eaton Fuller Mechanical Transmissions TRSM0992 Service Manual – PDF DOWNLOAD
The 2-A-92 model is a two-speed auxilliary transmission, designed primarily for use with heavy-duty transmissions. This transmission contains two sets of gears, thus giving the reduction (low) ratio when power is delivered through the two sets of gears. The other speed is obtained by direct (high) drive through the auxiliary.
- A single shift bar in the right side of the case controls the speed changes. When the shift bar is moved 7/8″ forward from neutral, the mainshaft sliding gear locks the mainshaft to the drive gear and shaft, thus delivering power directly through the transmission.
- When the shift bar is moved 7/8″ to the rear from neutral, the sliding clutch locks the mainshaft bushed gear to the mainshaft, thus transferring power through the two sets of gears to obtain the reduction ratio. The 2-A-92 has a solid countershaft with an integral low speed gear and a press-fit drive gear.
Preventative Maintenance Check List:
The following maintenance checks can be made without removing the transmission from the chassis. Items 1 through 5 can be performed without any prior mechanical work; items 6 through 8 require the dropping of the output driveline and the input driveline
where possible.
1. Oil Leaks
• Make visual checks for oil leakage from mainshaft openings, gaskets at bearing covers, top cover, and from front rear shifting bar bores. Check drain plugs for losseness.
2. Gear Lubricant
• Remove filler plug in right side and check oil level at regular service intervals.
• Change oil at specified intervals, using grade and type recommended.
Note: See Lubrication section for inspection, oil type, grade, and oil capacity.
3. Gear Shift Lever and Linkage
• Check the auxiliary gear shift lever for wear at mounting.
• Check shifting linkage for wear and looseness.
• Check to make sure exact neutral position of auxiliary gear shift lever corresponds to neutral position of auxiliary shifting bar.
4. Capscrews and Nuts
• Check capscrews in top cover and bearing covers for looseness which might be the cause of oil leakage.
• Check nuts on rear support bracket or plate for looseness.
