Flywheel runout -- 
 

The flywheel runout needs to be checked whenever misalignment is suspected. Flywheel runout 
should not exceed 0.10 mm 
 
To measure the runout; mount the base of the magnetic dial gauge on the block. Locate the dial 
gauge’s needle on the outer surface of the flywheel. 
 
Some of the common reasons for excessive runout are: 

 

Heat warpage. 

 

Improper machining. 

 

Incorrect bolt tightening 

 

Foreign material on crankshaft flange or flywheel. 

 

Improper seating on crankshaft. 

 
If the flywheel has been removed for resurfacing or replacing the pilot bearing then while fitting it 
back ensure that: 
 

 

No dirt and grease present on the mounting face (it can cause cocking & run out) 

 

 

The flywheel bolts have been replaced.  

 

 

Torque tightened as per sequence and also the angular tightening  as per the specification is done.  

 

Absence of any of these requirements may result in bolt loosening causing flywheel runout. 

 

Clutch cover & Disc runout -- 

 
Check the clutch disc runout before fitting. It should be within the specifications. If it is more than the 
specification- use a different clutch plate. 
 
A warped cover or diaphragm spring will result in clutch grab and / or incomplete release of clutch 
plate. 
 
If the clutch alignment tool is not used then the misalignment of the clutch plate can cause distortion 
of the cover and also disc damage. 
 
The cover can also get misaligned due to improper tightening of the cover onto the flywheel. The only 
way to avoid is that the bolts must be tightened alternatively (diagonal pattern) and evenly i.e. 2 to 3 
thread a time only. 
 

Clutch Housing Misalignment – 

 
The clutch housing has to be aligned with the engine so that the input shaft is aligned with the 
crankshaft. Absence of this alignment results in clutch noise, incomplete release of the clutch plate. It 
can normally be judged by uneven wear of the finger and pilot bearing. In severe case it can also 
damage the spline of the input shaft and clutch hub’s well as the clutch splines  
 

 

Normally the clutch housing misalignment is a result of: 

 

Incorrect seating on the engine/transmission. 

 

Missing alignment dowel holes. 

 

Loose or missing mounting bolt. 

 

Mounting surfaces that are damaged/ not parallel.
