Rotor to Shelf Clearance

The Rotor to Shelf clearance is the distance between 

the Shelf of the Housing and the bottom of the rotor. 

This clearance is best checked using a Feeler Gauge. 

Note:

 A Spider has a smaller Rabbit than the cover.

Note: 

The Spider is not present in the photos to provide clarity of 

the clearance.

Blade to Slot Clearance

The Blade to Slot clearance is the clearance between the 

Blade and the Rotor. 

All four Blades should be checked for the clearances on  

both sides of the Blade, for a total of 8 measurements. 

The clearances should be measured with the Blade at 

transition, meaning half way through the Blade’s travel 

(Figure 14).

 

Blade Top End Below Rotor Clearance (Rotor Re-

moved)

The Blades need to be equal to the Rotor height or 

slightly shorter (see Table 4A). If the Blade is too short 

or taller than the Rotor, it can affect meter performance.

The best way to effectively check this clearance is with a 

Depth Micrometer (Figure 15). The Blade Retainer may 

need to be removed to allow the Micrometer to sit flat.

 

Blade Bearing to Cam Clearance (Rotor Removed)

This clearance checks the wear between the Cam and 

Blade Bearings.

When parts are replaced, the clearance assures that the 

assembly is not too tight or loose for the rotating assembly.

The most effective way to check this clearance is with 

a dial indicator with a magnetic base (Figure 16). When 

checking this clearance, make sure to push and pull on 

the extended portion of the Blade to ensure the clearance 

is properly acquired.
