Table 43: Permissible clearances N and R
1. Push the feeler gauges (01) into the gap such that there is no clearance. The upper direc-
tion (N1) and lower direction (N2) must be covered simultaneously.
2. Calculate clearance N and compare it with the permissible values in the table.

tion (R2) and lower direction (R1) must be covered simultaneously.
4. Calculate clearance R and compare it with the permissible values in the table.
