'51 Chieftain - Transmission overhaul

Recommended Posts

I lost count of how many times I took the gearbox apart today.

 

I think I found the issue though. Snap ring that holds the front drum on to the secondary shaft didn't seat right because the new annular piston lid is slightly taller than the old one. 

 

I need a new pair of narrow snap ring pliers.

 

Hopefully I can take a couple thou' out of the buffer washer and get it all to sit right.

No, something's different. I do have the return spring and I need to see what that pushes against- if it's held by the back assembly or not.

Back to wiring today to get my mind off stupid errors. Dash gauge harness complete.

Added bonus:- it all works.

I'm in a bit of a tighter budget than that allows, really. I just want to make this safe and as tidy as it can be.

With the lights on the ammeter registers the battery discharging, the warning lights work and the gas gauge now even works- it shows the tank isn't quite empty.

I ended up, for now, fitting the car style switch by removing the bracket that holds the correct switch.

 

Wired up the back up lights, blower fan and brake lights. Those all now work.

Took the driver's side door switch apart, cleaned and adjusted the mechanism and reassembled. The door now operates the dome light correctly.

The dome light switch was jammed from the day I got the car, so I pulled it apart. It has overheated a little in the past and had melted out of shape. I filed it back into shape so the spring loaded contract is free to move and now it operates the dome lamp correctly. 

 

Onward and upward.

It helps greatly if the timing is set correctly. I found my timing light and set the timing up as per the book. It was nearly 45 degrees advanced; previous keeper had indexed the plug wires incorrectly. Surprised it was running before, thought it was a little lumpy...

 

Gearbox parts should be here Thursday or Friday, hopefully then I'll be able to reassemble that and get it bolted up to the engine.

Got the rear servo preload adjustment set- 5 7/16" from pin to end of servo.

 

20190927_201950.thumb.jpg.8d310bebecb04f9114d0d59088bdf86d.jpg

All tightened up. Front servo is a bit more fiddly but I made a tool by tapping a thread down the middle of a brass hydraulic fitting and using that to pay the piston down 0.3".

Front band then is snugged up and locked in place.

Figured I could clean it down and put a little paint on, too.

Fluid coupling put in place. Currently trying to remove the remains of the old flywheel seal.

Flywheel bolts progressively torqued to 30 lb/ft.

Almost to the point I'm going to fill it up with oil- need to do a couple things in the car in terms of looming wires and such and then I can put it back in.

Just filled it up and idled it and topped off again but revved up it cycles through all 4 gears happily now. Next up, valve lash again, finish looming the wires in the engine compartment with tape then I can reinstall the powerplant.

 

I call that a result.

Final lash adjustment while access is easy.

Make prep to put it back in. Need to get some bolts for the rear cradle.

Heavy thing it is, too. Started on lowering the engine and transmission into place.

 

20191003_223930.thumb.jpg.8009adb9f36f4c49c9263bf3af6a6ae4.jpg

Bit of a fight later and it's in and starts up. Manifold isn't sealing worth a hoot so need to slacken that off and redo.

 

I stink of old stale fuel. Put a few gallons in the tank just to freshen it up a little. Gauge reads quarter of a tank full now!
