Adjustment — Side Bearing Preload (Cont'd)
PD-22prose procedureLeft side formula applies to Europe models (T₁); Right side formula applies to Except Europe models (T₁). For T₂: Right side = Europe, Left side = Except Europe.
Side Bearing Preload (Cont'd)
Example:
A = 4 H = -2
B = 3 E = 0.18
C = 5 F = 0.15
D = 6 G = 0.08
Left side: Europe
Right side: Except Europe
T₁ = (A − C + D − H) x 0.01 + 2.07 + E
= [4 − 5 + 6 − (−2)] x 0.01 + 2.07 + 0.18
(1) A .................. 4
−C ................. −5

∴ T₁ = 2.32 mm
Right side: Europe
Left side: Except Europe
T₂ = (B − D + H) x 0.01 + 1.97 + F + G
= [3 − 6 + (−2)] x 0.01 + 1.97 + 0.15 + 0.08

∴ T₂ = 2.15 mm
