1. Excessive starting voltage by using high volt­age booster.

2. Excessive torque.3. Internal short against sheath.

IGNITION COIL, SPARK PLUGS, GLOW PLUGS AND BATTERIES

1. Before installing the spark plugs, clean theseat around the spark plug holes in the cylinderhead.

SPARK PLUGS

2. Check the spark plug gaps. (Illust. 1.)(Refer to "SPECIFICATIONS J " Section 1. )

3. Screw the spark plugs into the cylinderhead using a new copper gasket with each one.Do not tighten more than enough to compressthe gasket to seal the plug and assure a goodheat transfer between the plUR and the cylinderhead. Torque the spark plugs to 31 ft-lbs. Ifa torque wrench is not available, tighten plug1/2 to 3/4 turns past finger tight.

GLOW PLUGS

4. Connect the spark plug cables in the properfiring order.

A glow plug is primarily a heating element.IH direct starting diesel 236 and 282 seriesengines are equipped with glow plugs, theirpurpose being to ignite the fuel sprayed into theprecombustion chambers at the time the engineis being started. (Refer to operator's manualfor starting procedtlres. ) (Refer to Illust. 8.)

5. OIL SEAL: Inspect the oil seal in the bevelgear be a ring adj us t e r . If the seal is mutilatedor oil has been leaking into the clutch com.par­ment, replace with an oil-soaked seal placedso the leathe r lip of the seal face s toward thecoupling. The coupling can be used to drive inthe seal.

6. Inspect all parts for wear and damage andreplace if nece ssary.

7. Check the splines of the shaft, coupling andhub for exces sive wear or damage and replaceif necessary. Small burrs on the splines canbe removed with a fine stone.

8. Inspect the release fork upper and lowerbushing s for exce s sive wear and dam.age andreplace if necessary. Refer to Par. 2,"SPECIFICATIONS, II for dimensions of newparts.

9. Inspect the clutch release assembly for ex­cessive wear or, damage. This includes the re­lease fork finger width, the release pin bushinginside and outside diameters and the releasecollar trunnion diameters. Refer to Par. 2,"SPECIFICATIONS, "for dim.ensions of new parts"

1. BEARINGS: The release thrust bearing canbe inspected without rem.oving it from. the re­lease collar. If the bearings (including the pilotbearing) are in good condition, thoroughlygrease them and cover them until ready forassembly.

2. DRUM AND HUB: Check the surface of thedrum. for scoring. A scored drum can beplaced in a lathe and turned down not to exceed0.015 inch. If it does not clean up, replace witha serviceable drum. Check the teeth inside ofthe drum and outside of the hub for wear. Move­ment' of the clutch disc may develop notches inthe teeth. Replace either the drum or the hubif the teeth are worn excessively. Small burrscan be removed with a stone. The outside ofthe hub and the inside of the spring retainerrnust be smooth.

3. DISCS: Place the discs one at a time on asurface plate or under a straightedge to checkfor warping. If a 0.005 inch feeler gauge canbe inserted between the disc and surface plateor straightedge, replace the disc s. If discteeth are damaged, replace the discs.

4. PRESSURE SPRING: Replace the springif it is cracked or broken or if it does not comeup to specifications given in Par. 2.

12. REASSEMBLY

1. Install the steering clutch spring by placingthe spring in the retainer, and the hub (splinedend up) and pre s sure plate on top of the spring.

5. Place the assembly on a bench and installthe clutch discs as shown in lliust. 16. Blockthe drum. so the shaft will clear the bench.

Place the disc s in position over the hub. Thefirst disc installed must be a friction disc(teeth on inside diameter). The balance of thediscs should then be alternated by installing adriving disc (teeth on outside diameter) and afriction disc. (Refer to Illust. 16.)

6. Secure the hub plate to the hub. Turn theassembly over and rem.ove the three 7/16 inchbolts holding the pressure spring compressed.

STEERING CLUTCHES

lliust. 15Installing Clutch Hub and Spring Assembly.

Arrange the pressure plate on the hub so theprongs of the retainer are centered in the holesof the pressure plate. Place the unit in a pressand compress the spring. (lliust. 14.) Installthe dowel screws and lock washers and installthe bolts in the tapped holes in the pressureplate to hold the spring compressed. Removethe unit from the pre s s.

STEERING CLUTCHES AND BRAKES

2. If replacement was necessary, tap a newpilot bearing (33, lliust. 8) into the clutch drumfrom the outside until the bearing ring bottomsagainst the drum.

3. Block the clutch drum and position the bear­ing spacer in the drum. with the flat side up. In­stall the hub and spring assembly in the clutchdrum with the pressure plate down. (nlust. 15.)

4. Align the splines on the clutch shaft with thesplines in the hub (27, lliust. 8) and tap theshaft into the pilot bearing. Install the stakenut on the end of the shaft and torque to180-220 ft. -lbs.

7. Place the release collar (19, lliust. 8) withbearing over the clutch shaft so the lubricatorhole will face the rear of the tractor when theclutch is installed. Apply a film of oil to thefringed surface of the bevel gear bearing ad­juster before sliding into the collar. Slide theas sembled bearing adjuster onto the clutchshaft and insert the coupling (16, Illust. 8) ontothe shaft to engage the splines. (lliust. 9.)

10. Coat the O. D. of the seal with a light coatof Noo 3 Permatex and the rubber sealing ringwith roller lubricant. (Refer to Illust. 34.)

NOTE: The suggested method of applying Per­matex to the seal, is by first spreading a thincoat of the compound on a flat hard surface;then roll the seal over the coated surface andsufficient Permatex will be picked up. Removeany excess compound after the seal is installed.

11. Position the new oil seal onto the installingblock and shaft with the dowel pins facing up.Place the oil seal driver (Ulust. 31) over theshaft and onto the seal and pres s the sealevenly into the roller (Ulust. 33).

NOTE: When pressing the seal into the rollerbe sure the outside diamete r of the seal isinstalled no deeper than flush with the rollerbore (Illust. 35.)

NOTE: When installing the second seal, ex­treme care must be taken to be sure the rollerassembly is not supported by the first seal.THE ROLLER ASSEMBLY MUST BE SUP­PORTED ON THE PRESS BY THE ROLLERFLANGES ONLY. (Refer to lllu·st. 33.)
