FITTING FITMENT OF 330 DIA CLUTCH

Installation and Maintenance

1. Flywheel preparation.
Ensure the Flywheel friction face is free of cracks, scouring, dishing and taper. If found necessary, remove the Flywheel for re-work or replacement.

2. Checks for Flywheel Mis-Alignment
· Check the Run out of Flywheel - Clutch Housing Mounting Surface With respect to Flywheel Housing (see fig 3 ).
· The centre line or Axis of the Engine, Flywheel, Flywheel housing, Clutch, Clutch Housing. and Transmission shall be common to these units with a permissible variation of not more than 0.2 mm.
· If the Flywheel is reworked by regrinding the Friction Face, it is necessary necessary to requalify the thread depth to ensure that the Clutch mounting Bolts do not bottom (Fig 4)





3. Clutch Mounting ·

Lipe Driven Plates are Part marked and identified "Pressure Plate side". Clutch Driven Discs should be installed as shown in Fig 5.
· Before Driven Discs are installed, smear the Hub Splines with High Melting Point Grease.
· Fit 2 off guide screws on Flywheel and offer the Driven Disc assembly and Cover Assembly over the Alignment tool and 2 guide Screws.
· Fit cover assembly on Flywheel using 7 off Spring Washers and Bolts and finger tighten. Remove guide screws and fit the remaining 2 bolts.
· Tighten the clutch mounting bolts in the sequence shown in Fig 6 to a torque of 47/54 Nm? (Mm) ?

Caution :

Remove Hold down bolts!
There are 3 numbers of factory fitted hold down bolts with washers and these are provided only for transit purpose as also to nullify the clamp load while removing the cover assembly from the flywheel.

1) During fitting / fitment ?of clutch on to the vehicle these Hold Down Bolts should be removed after the civer assembly is screwed on to Flywheel and before removal of Alignment Tool. Coil Springs apply the Clamp load only when the Hold Down bolts are removed.

2) During removal of clutch from the vehicle, fit the Hold Down Bolts to the clutch before removal of Alignment Tool and before dismantling the clutch from the Fly wheel. This will ensure that the clutch setting is not disturbed and clutch is not damaged during transit.



Clutch Housing with Clutch Release Fork

§ Apply High Melting point Grease over the Contact Surface between release bearing Washer and Collector ring. (see `H`point `H` fig 7).
§ Lubricate Spherical Bearing of clutch release fork with high melting point grease (Point `X`-fig 7) and between clutch release fork and Release bearing (Point `Y` of Fig 7).

Failure to lubricate in time will lead to premature wear & tear.



Other Lubrication Points
• Hub splines
• Clutch pedal linkages.
• Slave cylinder linkages.
• Master cylinder linkages.

FITTING OF 352 DIAMETER CLUTCH

FITMENT OF 352 DIA CLUTCH

Installation and Maintenance
1. Flywheel preparation.
Ensure that the Flywheel friction face is free of cracks, scouring, dishing and taper. If found necessary, remove the Flywheel for re-work or replacement.
2. Pilot Bearing:
Check the pilot Bearing and replace if necessarty,
3. Checks for Flywheel Mis-Alignment.
a. Check the Run out of Flywheel. -
b.Clutch Housing Mounting Surface with respect to Flywheel Housing to be within 0.2 mm.(see fig 5).



The centre line or Axis of the Engine, Flywheel, Flywheel housing, Clutch, Clutch Housing. and Transmission shall be common to these units with a permissible variation of not more than 0.2 mm. c. If the FlyWheel is reworked by regrinding the Friction Face, It is necessary is necessary to requalify the thread depth to ensure that the Clutch mounting Bolts do not bottom.

4. Clutch Installation:
a. Lipe Driven Discs are Part marked and identified "Pressure Plate side". Clutch Driven Discs should be installed as shown on Fig 5.
b. Before Driven Discs are installed smear the Hub Splines with High Melting Point Grease to specification:
c. Fit 2 off guide screws on Flywheel and offer ? the Driven Disc assembly and Cover Assembly over the Alignment tool and 2 guide Screws.





d. Fit cover assembly on Flywheel using 10 offspring Washers and Bolts and finger tighten. Remove guide screws and fit the remaining 2 bolts.
e. Tighten clutch mounting bolts in sequence shown in Fig 6 to a torque of 47/54 Nm. (Mm.)?



5. Transmission installation of TATA Vehicles ;

a. Grease the clutch housing cross shaft bushing.
b. Apply High melting point Grease on the contact surfaces of the yoke and bearing housing pads(Fig 7). Ensure that the release yoke is fully raised and clears the bearing housing.
c. Move the transmission properly oriented and guide the input shaft into the sleeve bushing of Release bearing.
d. Ensure that the transmission axis is aligned to the Engine - clutch axis, and the release bearing is not subjected to any side loads.
e. Ensure that the transmission input shaft splines are aligned to hub splines and rotate the transmission shaft for ease of insertion.



f. Rotate the yoke tips back in to operating position and push the Transmission fully till it enters in to the pilot bearing. Complete the rest of transmission and clutch system installation as per vehicle manufacturers recommendation.
g. Clutch housing of G 50 gearbox.

Picture shows the clutch housing of G50 gear box with the yoke tips rotated back for installation of clutch. In G50 design the clutch housing is not a part of Gear box assembly but mounted upon the engine.



Clutch housing of G 600 gear box.

In the G600 gearbox assembly clutch housing is a part of the gearbox and the gear box assembly together with clutch housing is mounted on the engine Flywheel housing. Figure shows the clutch housing with the yoke rotated to ? just before being mounted on the engine.

Caution:
Please ensure that while mounting gear box on the clutch housing in G50 or mounting Clutch housing with gearbox on engine Flywheel housing on G 600 that the transmission shaft is inserted withoput any side loads on clutch release bearing.



h. Whether it is a new clutch or old clutch refitted or reconditioned clutch, the procedure for clutch setting is the same as explained in part 8 of the manual.
i. After completion of the setting, vehicle to be checked as per check list in Table 1 Part 4 of the manual.
