Is there a difference in a 2.0L out of a bus as opposed to a 2.0L out of a 914? I was under the assumption that a bus engine had different heads. I don't know where I heard that. Maybe I just made that up.

Bus crankshafts have the pilot bearing (same part as the one used in a 914) installed in the crank because the mainshaft is longer. Bus cranks for use with an auto trans don't have the bearing. 914s have the bearing in the flywheel. The bearing in the bus crank doesn't interfere with anything in the 914 application, so it can be left in place.

The Cap'n True, but when I have had the cranks worked on they pull the bearing so "IF" you are going to use a crank without the bearing put a bearing in or that stop. Otherwise the bearing on your 914 flywheel will move around into the crank and the pilot shaft will flop around. Nah, the rods and crank are the same, even have a 039 part number as Porsche figured out how to built the 2.0L as VW thought you could only go to 1800 with a 66mm stroke. |

Do you guys just sit around making this shit up? The needle bearing is pressed into the flywheel. If it moves, there's something wrong with the flywheel. The Cap'n |
