Using Loctite 660 to repair a stripped splined shaft
Вставка

- For repairing tubular or cylindrical mating surfaces, like the door handle or the window crank on this old Ford COE truck, Loctite 660 is a fantastic solution. I had several options for fixing these stripped shafts and handles, such as pinning them or cutting keyways. But I was able to avoid that complexity with some Loctite 660.
Loctite 660 isn't an adhesive, like the epoxy the prior owner tried to use to fix this...and which failed. It's some kind of magical compound with (what looks like) metal suspended in a hardening base. When cured, it fills gaps and prevents the poorly mating splines from shifting relative to each other...locking the handle and the shaft together.
Easy peasy, lemon squeezy!
These anaerobic adhesives cure by a chemical reaction with the steel. It works with aluminum also, but not as well.
Good tip. Enjoyed the presentation and learned something.
Well, coming from someone I look up to greatly that means a lot, Sir Phil. Thank you!
Worked great! Thanks
What happens when you have to remove to get behind the panel? Then will you have to purchase replacement parts?
By that time it'll probably already be in the scrapyard.
Looks good but won't work if you have door panels
Has the job held up ever since?
Quite well so far, yes.
This calls for FARM QUICK TIME REPAIR ( FQTR ) , weld a Garbage Freight wrench onto the window regulator shaft ! Use a chrome wrench if you really want to be FANCY .

Where does one find the bamboo paddles? Thanks
We got them from a restaurant supply store. If you search "bamboo paddle skewers" you should find sources. There are lots of things that work, but we've found these to be really handy.
@@RollingLiving thank you
Use a kebab stick or tooth pic
Thank you good Sir - I have a damaged spline shaft as well for a motor, and you have given me the idea how to repair it.
God Bless, from Singapore!
How are you going to get back inside the panel? Now you can't remove the handles ...
You just don't
Just wondering if this works in below freezing conditions? I put this on a keyway 2 days ago and it's still not set!
It wants 15 degrees Celsius at least. But it also cures better/stronger if it is denied oxygen (e.g. squashed between surfaces)
Henkel's specifications say it repairs gaps "up to 0.020" diametral clearance". That is a very small gap! The gap in my worn window crank's spline is much bigger, and because the crank is aluminum and the job would require the Activator, I'm giving up and getting a cheap new window. Thank you very much for this UA-cam series, though.
a damn, i thought i was going to see a spline repair that can take some beating. But this is just for to crank up and down a window.
I got a moped. Tomos.
The crank shaft has splines to connect to the clutch assembly.
Both the splines from the crank shaft and the clutch assembly have been stripped out.
Almost flat.
That aint ever gonna work with just loctite.
So my guess is taking the drill and drilling a few holes for to put in metal rods or splice pins or how you call em......
Anyways, it is a nice fix for something like this. Agreed.
