The DoAll 16" LHF Bandsaw, Part 5:
Now we can reassemble the gearbox itself. A simple matter of first pressing the new bearings into the cleaned housing...
The input shaft gets its dog clutch element and a new center bearing...
Which gets gently pressed into the center.
The large plain gear and it's thrust washer go in the lower chamber.
As noted earlier, the long spiral gear had some burrs left over from the original machining.
Just for a little preventative insurance, I carefully ground those off so there was no chance
they'd come loose into the oil at some futire point.
And that gear, along with the pump eccentric, goes through the plain gear and into the lower bearing.
Next up, the pump itself is installed and bolted down.
Then the center dog clutch element and the shifting fork...
And after that, our newly-repaired output shaft, which needs these two keys.
All together like so.
Now the upper gear with the dog-clutch teeth...
And its thrust washer.
I used the output side cover as a template to cut out a gasket, and hit it with a coat of gasket tack before assembling.
Due to the fit of the output shaft in it's bearing, I had to lightly press the two halves of the case together.
Right aboout that time, I was telling myself, hey doofus, you should have pressed it into the case half,
then assembled it- it slips right into the dog tooth ring.
Anyway, I then added the shifter eccentric assembly.
And finally the outer bearing covers.
As I didn't have any pieces left over, and the shafts all turned smoothly and quietly,
it was a simple job to go ahead and bolt 'er back in place!
Hey, did I remember to put oil in there...? :)
