A new thread. Or renew thread
« on: November 04, 2021, 09:07:29 PM »
I’ve had a a few screws / button head bolts that wouldn’t move to come out. Too much. Thread lock? Or tight threads from chroming? What a struggle to get them out.
I’m a Journeyman Millwright and still had to endure the stress…..
Once they are removed. Tap the threads and clean. Much better.
Finally got the backrest windshields brackets loose. #%&$. 
The removable bags were not very removable. Off now. $&%#.
Back to the core of it to reduce all the gear for winter service.
 
Install the crankcase vent to rear fender inside from the taillight
I’m going to replace the stator so I know what I have and the time it’s been in use
Back to stock bars and mufflers
Check the primary for updates
And more….

Awesome plan. I wondered about stuff like the mufflers and bags. Any idea why those mufflers? Were they different sounding or just for a different look?

Yes, welcome to the world of our fasteners. Since a bunch of us owners only own the one brand of bike, we tend to think of these decisions like the thread locker as being somewhat exclusive to the brand. The truth is that the more I've looked, the more I see thread locker patches on all kinds of new fasteners and even plumbing parts.

The stuff on our fasteners is a dry, pre-cured compound, coated on the fasteners from the manufacturer. Upon installation, the locking compound is activated by the shearing and mixing in the threads. Once it sets, it provides the locking feature. If you buy any NoS screws for your bike, the dreaded orange patches will be found on almost all of them.

Here is the product: Precote 80

https://www.precoteusa.com/products/precote-80

Like many of the things on these bikes, the engineers so overshot the target that we're left dealing with these blasted fasteners even 20+ years later. Hey, they didn't come off, right?  ;D

The trick is heat, lots of heat. Probably more heat than any of us think. I believe it has to be above 350F (175C) before it releases. I often use a propane torch with self-fabricated heat shields (piece of metal sheet with a hole drilled to act as a mask around the fastener). For places where powdercoat or paint is at risk, a really big soldering iron gets used that was bought for stained glass windows. It's slow but, has done the job in the past.


I was renewing the handlebar rubber isolators on one of the bikes a few weeks ago. The heads stripped hopelessly. I drilled the heads off and ended up having to pull the handlebar riser studs as well. I could not get the stumps to back out.

Into the lathe they went. I chucked them way out so little heat transferred through the jaws. Slowly spun the chuck at 300 RPM and used the propane torch to heat the shank. I wanted blood. Eventually the Precote 80 turned black and started to smoke out of the threads. At that point, the remains of the screws backed out with zero effort. It probably didn't need to get that hot but, it worked.  ;D

So--yeah--if it's something you can pre-heat, do it. If it gets away and has to have the head drilled off, heat the stump with a vengeance. It will release.

Ahh, I just realized this was Jackie Hale's bike! That was a couple of years ago. I'm with you now.

Something came to mind about your bags. I don't remember all the details when Jackie owned it but, more than once considered buying it. Does it have Easy Brackets?


https://www.greatbikegear.com/product/easy-brackets-for-excelsior-henderson-super-x/

If so, in a lot of ways, that's a heritage accessory for us. You may remember this from back in the day. There weren't many aftermarket accessories ever made for our bikes. So why is this product still available for our bikes 21 years later? The guy who designed them is/was an original owner. He shared the details of designing and making the first pieces on the Yahoo boards.

I have a set of his brackets here, though I never installed them. I have plans to get some bags for them and install them on the Deadwood. I like that bike naked most of the time but, bags--ya' need bags sometimes.

With that said, I started to install the brackets (exactly two years ago, that show is this Sunday) and something wasn't right about the peg spacing. I couldn't get the brackets to quite line up with the holes. It was turning into a science project and the bike had to be done. It went back together with factory screws. Is that what's wrong with yours too?

The brackets were locked on with a tubular lock. The keys are missing. So I disassembled the mechanism from below.  Should release the bags, yes.  No, they were tight as heck. 3lb hammer to encourage a little movement. Then managed to pull them off. I’m not sure why they were so tight. Might be oxidation from being on so long. I believe that being tight keeps them from rattling.  I’ll measure and check further.
