Do I need part 301100? My bus has already been converted to 12 volt and is running a 12 volt starter. I am putting in a different engine with a 6 volt flywheel. So, I purchased the 12 volt starter with a 6 volt gear from your website on Saturday. I just noticed the section indicating I need this part as well.
On our special 12 volt starter with the 6 volt drive gear it must have a 12 volt size bushing in the bell-housing to support the Bendix gear shaft. If your transmission already has the 12 volt starter bushing you will not need any additional parts and it should be a simple bolt in swap!
