FIGURE 10 - Water Pump Impeller, Shaft & Bearing Removal
1 • Press Adapter 2. Shaft
4. Place the water pump assembly on the press with hub end down. Support the pump on the housing edges of the bearing bore, Figure 10, so that the bearing and shaft can be pressed past the supports. Press the shaft and bearing assembly out of the pump body. Remove the impeller from the pump.
5. Support the pump on the impeller end, and press the seal from the housing.
INSPECTION AND REPAIR
Repair of the water pump consist of replacement of worn or damaged parts.
1. Check the condition of shaft and bearing assembly by rotating the bearing. If the bearing is binding, running dry from lack of lubrication, or feels rough, the shaft and bearing assembly must be replaced.
3. Impeller
IMPORTANT: DO NOT clean shaft and beari ng assembly in cleaning solvent because the lubricant will be washed from the bearing.
2. Thoroughly clean pump body with non-toxic, nonflammable solvent.
h WARNING: Never use gaSOline or diesel .. fuel or other flammable fluid for cleaning
parts. Use commercial, non-flammable, nontoxic solvents.
3. Check condition of bearing bore in the body. Replace pump body if cracks are evident, or if bore is severely scored.

2. Place cylinder head on blocks; depress the valve spring with tool ACTP 10294 illustrated in figure 45 and remove the valve spring retainer locks. Release the valve spri ng depressi ng tool and remove the valve spring retainer and the valve spring. Place valves in a rack as they are removed from cylinder head so they can be identified and rei nstalled in their origi nal locations.
3. Clean the carbon from the valve and valve seats. Clean the carbon from the valve guides usi ng a valve guide cleaning tool (nylon brush) similar to the one illustrated.
IMPORTANT: Do not use a metal cutting type cleani ng tool.
4. Replace the intake and exhaust valves if they are cracked, bent, burned or the stems are worn. The specified 0.0. of the exhaust valve stem is .3705" to .3710" (91.41 to 9.42 mm). The specified 1.0. of the exhasut valve guide is 0.3735 - 0.3742 (9.49 -9.50 mm) giving stem-to-guide clearance of .0025 to 0.0037" (0.06 - 0.09 mm). Replace exhaust valve and/or guide if clearance exceeds .0055" (0.140 mm). The specified 0.0. of the intake stem is .3715" to .372" (9.44 to 9.45 mm). The specified 1.0. of the intake valve guide is .3735" to .3742" (9.49 - 9.50 mm) giving a stem-to guide clearance of 0.0015" - 0.0027" (0.04 - 0.07 mm). Replace intake valve and/or guide if clearance exceeds .0035" (.089 mm).
NOTE: Valve guides in new production and new factory service heads do not require reaming in the field. They are factory beari ngsized to .3735" to .3742"(9.49 t09.50 mm).

CAMSHAFT GEAR AND CAMSHAFT INSTALLATION
1 . To install gear to camshaft proceed as follows:
a. I nstall key in keyway.
b. Place camshaft in a press with the shoulder of the first journal resting on parallel bars. Figure 117.
NOTE: The thrust plate must be positioned on the camshaft before pressing on the gear.
c. Heat the gear in oi I to a temperature of approximately350° to 400° F (176° to 204° C).
CAUTION: Use gloves to handle hot gear to prevent burns on hands.
d. Using gloves, position the gear on the camshaft and align the gear keyway with the key in the camshaft.
e. Press the gear onto the shaft until the gear hub is flush with the front end of the camshaft. Check for specified clearance of 0.003" -0.009" (0.07 - 0.22 mm) between the thrust plate and the gear hub. Figure 110.
f. Tighten capscrew to 72 ft.-Ibs. (97 N . m); lubricate threads.
2. Check cam bearing running clearance. (See previous section).
3. Lubricate valve lifters with clean engine oil and install them in their original locations in the cylinder block.

4. Lubricate cam bearings with clean engine oil and carefully insert camshaft into cylinder block.
NOTE: Make certain the timing marks on camshaft gear and crankshaft gear are al igned when camshaft is installed. See Figure 118
5. Install lock bolts through the thrust plate. Tighten lock bolts to a torque of 18 to 20 ft.-Ibs. (24 to 27 N . m).
6. Check the camshaft gear backlash. The specified backlash between the mating gears of the crankshaft and the camshaft is .0015" to .0085" (0.04 to 0.22 mm). Figure 119.

NOTE: Inner diameter of shim (S) is chamfered on one side. This chamfered side should be placed next to pinion head (rearward).
Place rear beari ng cone (31 b) on pi nion shaft so bearing seats against shim. Figure 72
I nstall seal (20) into front bore of rear mai n housi ng from front. Make sure garter spring side is to rear, and front face of seal is .748" (19 mm) for 6060/6070, or .827" (21 mm) for 6080 behi nd front beari ng cup's counterbore. Figure 63
Install front and rear bearing cups (30a & 31 a) into rear main housing, making sure cups' external lip seats agai nst housi ng.
Carefully install pinion shaft with shim and rear bearing cone into rear bearing cup from rear. Install thrust washer (32) and spacer (23 or 33). If tractor is 2WD, install spacer (23) with slot forward. If tractor is FWD, install spacer(33) (no slot). Figure 72
On FWD units, install key (35) FWD drive gear (42) and front spacer (34) (with slot). Figure 72

I nstall key (35) in pi n ion (19) and install parki ng brake hub (21) with two parking brake plates (29) over key. Make sure hub of parking brake hub (21) is forward. Slide pinion shaft (19) forward so parking brake hub (21) engages seal (20). Figure 72
Install pinion bearing adjusting shim(s) (SJ over end of pi nion (19), and install front beari ng cone (30b). Install pinion shaft nut (CJ and slowly torque to 217 ft.-Ibs. (294 N . m) while turning pinion. If bearings lock up, increase thickness of shim (SJ. Figure 72
NOTE: Use deep socket ACTP-3118 (55 mm) to torque front pi nion nut (CJ on 6060/6070 tractors. On 6080 tractors prior to power trai n serial number 713342, use deep socket ACTP-3119 (65 mm). On 6080 tractors above power trai n serial number 713342, use deep socket ACTP-3025 (70 mm). See Figure 60 for power train serial number location (7). For 6080 tractors, only pinion nuts measuring 70 mm across flats are available; thus socket ACTP-3025 will be required if new nut is installed.
Wrap stri ng (5) around pi nion shaft spacer (23 or 34) and attach spring scale (6) to string. Specified rolling torque of pinion shaft is 6 - 12 in.-Ibs. (.68 - 1.36 N· m). Using string and spring scale as shown in Figure 73, spring scale reading should be 4.8 - 9.6 Ibs. (21.4-42.7 N).

COMMUTATOR UNDERCUT
FIGURE 62 - Depth of Segment Mica
1-2 Depth of Segment mica (Figure 62)
Check segment mica for wear.
Standard: .020 to .031 " (0.5 to 0.8 mm)
Service limit: .008" (0.2 mm)
Replace armature if segment depth is less than service limit.
1-3 Check commutator outer diameter.
Standard: 1.417" (36 mm)
Service limit: 1.378" (35 mm)
Replace armature if commutator is worn below service limit.

FIGURE 63 - Armature Short-Circuit Test
1-4 Armature Short Circuit Test (Figure 63)
Check armature for short circuit by placing it on a growler tester. Hold a hacksaw blade against armature core while slowly rotating armature. A short-circuited armature wi II cause blade to vi brate and to be attracted to core. If hacksaw blade is attracted or vibrates, armature, which is short-circuited, must be replaced.

FIGURE 64 - Armature Ground Test
1 -5 Armature Ground Test (Figure 64)
Using a ohmmeter, touch one probe to commutator segment and other to armature core. There should be no continuity. If there is continuity, armature is grounded. Replace armature if it is grounded.
FIGURE 65 - Armature Continuity Test
1 -6 Armature Continuity Test (Figure 65)
Using a ohmmeter, touch two probes to two of commutator's segments. There should be continuity at any test pOints. Replace if commutator is open-circuited.
