This weekend the transmission arrived and I got everything back together. While waiting on the transmission I completed a few miscellaneous things:
- Replace bearings in the dynamo/generator (it’s not an alternator like in ‘modern’ cars)
- Fabricated replacement clutch cable, including making a new end link on the lathe. The end links were then crimped onto the cable with the 12 ton hydraulic press and soldered in place, so they shouldn’t be going anywhere.The clutch cable had partially broken and was stretching with each press, causing the clutch not to disengage all the way. This is what took the bus out of commission in December. Since it was still connected at both ends and not completely loose it seemed OK until I removed the pedal pan and saw many broken wires.
- Fabricated the special barrel nuts needed to connect the heater control cables to the exhaust heater boxes.
The test drive went very well, it’s noticeably smoother but noise levels are still quite high inside. Part of the noise level is a minor exhaust leak that I’m tracking down, but the new smoothness also allowed me to notice for the first time that a majority of the noise is from the axle reduction boxes. This was confirmed by carefully running in 2nd gear with the back wheels on jack stands – the bearing rumble then became even more noticeable. Replacement bearings are on the way and I should be able to swap them out with the engine/transmission still in place.
