Genrator Woodruff key(help)
Hey everyone.
Had to pull my beetles gen pully off today,last week it was making a ticking noise,and was slowly getting loose.Turns out that the key which sits on
the shaft was wearing.When i replaced the bearings a while back we noticed this with the original key,so had to fabricate a new one to match the new
shape.Had to do the same again today.It worked,no noise and keeping tight.(not sure for how long)
I cant afford a new gen at the moment.So i was wondering if anyone else has experienced this type of problem ? also (not especially) but are there any
products that rid of the key altogether?
The only thing in my engine bay that is not new 
Kind Advice please guys.
Thanks in Advance

Hi, You could try loctite super retaining compound in conjuntion with its primer,i think it is number 680, just use it to glue the key into the shaft,
if you use it on the shaft you probably would not be able to get apart again.

You can get used generators fairly cheap....
every engine had one... lol
heaps are about....
You can buy the original VW woodruff keys..
and You can also buy products to fix this...
loctite etc... holds the key in place....
that's what I would be using...
and they are able to be pulled apart with normal tools..

Personal experence tells me that it will , as long as the bore of the pulley and the key way in the pulley or the shaft is not worn it will work, this
wear happens after the top pulley has been loose, we use all types of loctite in critical area's of hydrocarbon production with no issues, you just
have to use the correct product for the application, loctite will not work if there is any trace's of oil or dirt, and works the best when it is used
in conjuction with it primer. dont glue the pulley on with the 680 as you will not be able to remove it without the application of heat, just fit the
key and let it set and make sure that the pulley is torqued correctly, it worth a try.

The bolt that holds the split pulley together done up to the factory recommended torque setting, this is done with a torque bar. it is good work
practice to torque all of the critical bolts on your car in this manner, it stops things like broken or stripped bolts and warped brake drums
occurring when they are over tightened during assembly. have a look in the manual and you will see that a value in neuton metre's or foot pound's
is listed for all critical bolts on your car

Have you concidered that the pulley is the faulty part here ??? ie it is now outer shape in it's centre and is constantly moving about on the genny
shaft and damaging the woodruff keys as no matter how tight you tighten the nut an eliptical hole is always going to work it's self loose on a round
shaft
Don't let body work get in the way of real suspension travel

rumour has it that to remove the 'fastening' properties of any stubborn loctite is to simply apply heat.
