The bus is on the lift
But something is missing
One of my ideas for the bus when fitting this bigger engine was to be able to use the power to make cruising easier, quieter and if needed, able to go faster without over-revving the engine.
So I sourced a 2L kombi geabox and had Bugger recondition it. This is to replace the lower geared 1600 gearbox
Like I said, I have been planning this engine build for a while
Two boxes together
Now you will see that the 1600 gearbox has a shorter input shaft than the 2L box.
The 1600 box was made for the type 1 (beetle) engine, while the 2L box was made for the Type 4 engine.
Now the correct way to fix this is to swap the bellhousings and also the input shafts around.
I swapped the bellhousing, but the input shaft I could not get out. All the tutorials online say to remove the input shaft after popping off the bellhousing. But this 091 gearbox must need it done in a different way as I couldnt get the shaft over the diff.
The diff in itself looks like a much larger unit than in the 1600 box and also has 4 spider gears unlike the 1600 box which only has 2. So its a massive upgrade as far as the gearbox's strength does.
How to fit the T1 engine to the T4 input shaft? Especially since I wasnt going to take a newly reconditioned gearbox apart.
Simple, take an angle grinder and remove 14mm off of the shaft.
Now the shaft will fit into the bearing in the T1 glandnut without bottoming out. Just remember that if you do this, and you wish to fit a T4 engine, you need to get a spigot shaft bearing and fit it to the flywheel of the T4 as the input shaft no longer reaches the bearing in the crank.
