TRANSMISSION. NOTE: If either a new transmission and differ
ential case or a new ring gear and pinion set is being installed, special Tool No. 21M-452-T with Adapter Rings must be used as described below.
Setting Pinion (Output Shaft), If a new ring gear and pinion (output shaft) or a new case is being installed, it is necessary that special assembly gauge AM-452-T with Adapter Rings be used to set the pinion properly in the transmission case. However, if only a new rear bearing cup or rear bearing cone of the output shaft is being installed this may be done without re-setting ring gear and pinion, providing same thickness of shims is maintained under the rear bearing cup of the output shaft.
Read and Understand this discussion before attempting to set pinion (output shaft).
SM (12-1-49) e
To insure that ring gear and plOlon assembly operate correctly and that tooth bearing of ring gear and pinion is correct, each set is tested at the factory and a number is etched on face of pinion.

Pump and Lines Tractor, Model "MT"-Touch-o-matic System 180-10-1
Group 10
TOUCH·O·MATIC PUMP AND LINES
DESCRIPTION In the design of a hydraulic lift system, the
location of the pump or other unit which supplies
the power is important, because it is desirable to
have the lift mechanism in operation at all times
even when the tractor is stopped. The oil pump for
the Touch-o-matic unit of the Model "MT" Trac
tor is mounted on the front of the engine and is
driven by a coupling on the end of the engine cam
shaft-thus the pump operates at any time the
tractor engine is running. Therefore the Touch-o
matic unit may be used when the tractor is stopped.
with the clutch disengaged as well as when the
tractor is moving with clutch engaged.

Figure 180-10-1-Touch-o-matic Oil Pump
Oil Pump*. The Dual Touch-o-matic oil pump
(Figure 180-10-1) is a gear-type positive displace
ment pump. A positive displacement pump of this
type is one in which all the oil picked up by the
teeth on the intake side is discharged at the outlet side of pump. This is accomplished by the operation of pumping gears located within a close-fitting, oil-tight housing. The drive gear shaft extends through the oil pump body directly engaging a spline type coupling on the engine camshaft. This gear is keyed to the shaft. The idler gear is not keyed to its shaft. In this pump the drive and the idler gears rotate in four needle bearings pressed into the body sections. The body is composed of three sections aligned by two dowels, to assure correct placement of gears in relationship to the body walls. A constrained gasket in a machined groove on each side of the center body section forms an oil-tight seal when the body is assembled. The body is held together with socket head screws, three of which are also used to attach pump to engine block.
REMOVAL IMPORTANT: When servicing any hydraul
ic system always use care and stress cleanli
ness. The least amount of dirt in the mechanism and lines or the smallest nick or burr on the metal can make the mechanism inopera
tive.
Always use wrenches which fit oil line or tubing
connections snugly. Do not use pliers to loosen or
tighten connections. Oil line connectors are easily
damaged when improper tools or methods are used
to tighten or loosen them.
Inspect the hydraulic system for oil leaks at any connections of lines to Touch-o-matic Unit, pump. or between the lines themselves at the upper and lower end of instrument panel. Check also for leakage at gasket joints and through castings.
Listen for possibility of air being sucked into system, which will cause malfunction.
Remove the hood and grille from tractor.
Drain the Touch-o-matic system at the rockshaft housing.
*The new design three-section "M" and "MT" pumps are not interchangeable. They are identical in outward appearance, except that pumps are stamped "M" or "MT" on pad of center section (Figure 180-10-1). Center sections and gears are of different design.
