REFLECTOR: Belleville washers

Sat Jun 20 11:43:59 CDT 2009

John, Dave, Chuck, Scott, everyone

Thanks for all that.  I will check on the brakes and try to reconfigure like
Dave has it.  That sounds very workable.  .and to others thanks for
reminding me about the brakes and rotors.I have forgotten about that.  I'll
check that too.  I appreciate all this advice.

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...?
