Component Disassembly & Reassembly: Countershaft: Inspection

Inspect all parts for damage and wear, replace if necessary. Clean all parts in solvent; dry and lubricate all parts. 3rd/4th and 5th gears should be installed with a press before lubricating them.
Measure countershaft at points "A", "B" and "C". See Figure . Use dial indicator to measure runout. Rotate countershaft 2 complete revolutions. Replace countershaft if runout or any part is not within service limit. See COUNTERSHAFT BEARING SURFACE SPECIFICATIONS table.
