REFLECTOR: Belleville washers

[David Scharfenberg]

Hi Terry,

I had a lot of trouble with the nyloc nut and found a castle nut at a  
truck repair shop.  Drilled a 1/4" hole in the gear leg and use a 1/4"  
bolt to lock the castle nut.  Haven't had to touch it in years.

John,
Thanks so much for volunteering that.  I recall that they went in  
originally smooth, primed and un-lubed.  The problem I have is  
adjusting the big nyloc to setting that is neither too loose nor too  
tight.  A bit of grease seems to increase the torque range  
tolerance.   The prime coat of paint is long since rubbed off and I  
thought the rust was part of my culprit.

If I were to say, it is steering problems I have and not so much  
shimmy problems.  I have an XLRG.  The only shimmy I see in when on  
the brakes in the latter half of the roll out, and then only when  
there is more wgt on the nose wheel from having someone in the right  
seat.  I am tempted now to take my 1/7/8 (or whatever size it is) end  
wrench over to the local welding shop and have then make a 1/2 fitting  
on it to fit my torque wrench.  The fish-scale-as-tq-wrench method is  
not working for me…and the end of wrench is so fat I can only get a  
few degrees of bolt rotation at a time before it hit the forks.

So people know, there are several different nose leg assemblies in the  
field with differing washer count.  Were I to add a nylon washer and  
not remove any steel washers, it would have to be in the thinner  
side.  As it is, I barely have 3 threads showing.

Terry,  The idea of Belleville washers is to develop turning friction  
to subdue shimmy.  You may want to wipe off the grease in order for  
the washers to transfer torque.

Whatever you got.  1/16th or so?  This is out of sequence some, but I  
have been removing, polishing off corosion, regreasing (just stock  
marine grease) and adjusting the tq to my bellvues on about a  
quarterly basis.  If you have a better mousetrap I'd be interested  
that's all.

I may still have a few made I will have to check. I made them in  
different thicknesses. what thickness are you looking for? Jeff

Jeff,
Could I talk you into making a set for me?  I'd gladly trade for free  
banjo lessons or $5 or whatever plus shipping.

I ordered some 2 1/2" round stock on line and opened up a hole to the  
right dia. using a lathe. It works great.

Where did you get the nylon sheet stock that you made the washers from  
and how many did you use?

I found that a combo of a home made nylon washer and a nose wheel lock  
makes a great addation to any velocity. no nose wheel shimmy and  
awsome steering (taxi) on the ground...Jeff

I have the 'thin' belleville washers (with spacer) - and plan on  
purchasing a new washer kit from the factory, but I thought someone  
had successfully been using SS washers - and had suggested McMaster as  
a source...?
