Main bearing kit - 1.00 case - STD crank - 22 - T1 - Silverline

Silverline bushings.

Quality

- respect of tolerances => medium 

- central tri-metal bearing => yes

- central bearing groove position => outer (wrong side)

- machining quality => medium

- availability => regular

- manufacturing => Silverline (Brazil)

- surface treatment => unknown

Our opinion The disparity of tolerances are the main defect. However, despite the lubrication throat on the block-side center shaft, longevity seems good.
