Default Re: Question about starters

The fact that both gears have 9 teeth means nothing. They need to have the same pitch diameter, tooth form and other factors which you can not measure. The pinion gear needs to match the flywheel perfectly or all manner of noise, wear, mis-mesh and damage will occur. You need to use the GMC pinion.
