It was time.
I replaced all four RollerHead (carriage) bearings. Not particularly easy, because the king bolt (the slotted thing in the center of this photo) had frozen, rendering the clamping mechanism inoperative, and nearly impossible to budge.
I love PB Blaster :-)
The clamping mechanism is the knob at the 4:00 position, in this pic. It works beautifully, now, giving nice linear feedback, as it clamps the yoke down:
Then, I cracked the motor, cut all the electrical wiring (to be replaced, in the next step), and pulled the front bearing. The bearing puller made short work of that job.
The old one did NOT turn easily. Good choice to replace it.
Then, I pulled the guts out of the motor, to access the back bearing.
Over time, the back bearing had galled to the armature. Long story short, I broke my bearing puller, and spent well over an hour beating the snot out of this thing, ruining a cheap chisel, and working up quite a sweat in the process.
It finally came off.
A little emery cloth on the armature, and a light coating of grease should prevent its recurrence. The back bearing didn’t turn freely, either. ALSO a good choice to replace it.
What it takes:
Every fastener that was removed was cleaned up and properly lubricated. The mating surfaces that allow the yoke to pivot needed a fair amount of elbow grease, but … after that … and once a thin film of synthetic grease was applied … the motor pirouettes elegantly :-)
The wires that exit the winding, and connect to both the power cord and the circuit breaker … are trash.
I’m tempted to take the motor to a local small appliance repair shop, and see what they think.
If I’m smart, I’ll get new windings, and a new circuit breaker with proper terminals. The wires from the power cord are soldered onto this breaker, making it difficult to re-use, once I put the new power cords on.
Time to be smart, and NOT be penny wise and pound foolish.
For today, I have to belt sand my hands (next time, I will wear disposable gloves), and have myself declared a Superfund site :-)
I’m trying hard NOT to consider a cosmetic restoration. I just want everything to WORK … perfectly.
But then I found THIS …. and suddenly … can’t even LOOK at my RAS, anymore:
Can you STAND it ??? It’s all powdercoated, nickel plated, balanced, blueprinted, stroked, relieved, ported, has twice pipes, and wide ovals on it. AAAAHHH !
So … aside from THAT (:rolleyes:) ... yeah … I’m having fun :-D
