FAIL! Collets 101

[farmersammm]

Made a new gasket, and started to install it................ Then I remembered that I hadn't locked the bearing adjuster nut Ruined the new gasket.......Hell......what else is new



Anyway...............I couldn't get the tabs to bend on the lock washer, without moving the nut, AND the washer. Turns out that the washer, being sized for a 1 9/16 shaft, won't properly fit the 1 1/2 resized thread. Too much slop. I remembered being concerned about that some time back.

I'd flattened all the tangs on the washer when removing it during the initial teardown. So....................I got to thinking.............

I figure, if I rebend the tabs to factory "new", they might centralize the washer on the shaft. Used the damaged nut, and another nut I bought when I originally hoped to simply restore the damaged thread. Using the press to hold the washer firmly, I then used a drift to bend the tangs to comform to the nut.





The washer is now centralized underneath the nut. It's very solid, and doesn't move at all. Set the damn thing again tomorrow. Closed up early, because by then I'd had enough for one day. Another stupid mistake.

I guess in some ways it was a blessing. I discovered some grit I'd missed when cleaning the gear case. Knocked it loose, and can now remove it before I seal it up again.

Rebending the tangs worked out great. Washer stayed centered, and the tang bent without effort, using a large pair of slip joint pliers. Final setting wound up being about .001 end play.

She's sealed up, and weather tight.

The seal that started this whole mess. I hope this will last till they shovel dirt in my face. The brown goo is open gear lube. I use it on all machined parts that have to temporarily sit out in the weather.

The final thing is to check the blade plate for flatness, straighten if necessary, and put it on the machine. This machine will obliterate Cedar Trees up to around 6-7' tall. Back in the day (I guess), they put heavy plates on these things. This a 1" thick plate. It acts as a flywheel, giving the machine incredible power. To me at least, this makes the machine worth repairing.

I'm always fascinated by machinery.

I was just noodling around, punching some numbers on the calculator

The shaft is threaded at 18tpi. That's about .055 per revolution.

The washer has 16 tangs. That's about .003 per tang. That's a pretty healthy range of adjustments. Pretty cool stuff. IIRC, axle spindles are threaded at maybe 20tpi, making them even tighter on tolerances when it comes to adjusting bearing end play.

The best way to stop a nut from coming is tack the nut to shaft.

So, you want me to go through all of this again in a few years, or maybe even a few months?????????????? This whole fiasco was because some moron messed up the thread in the first place You sir, are a dangerous fella

Only if you're a shortsighted bodger
