Hi All,



I have the steerable nosewheel with the bearing pre-load adjusted with 

bellville washers. I did not receive any of theses washers with my kit 

and on approaching Matco they informed me that they did not supply the 

washers and would not recommend this method of pre-load adjustment. The 

axle is 3/4 inch and you can see the installation on Bob Reed's site in 

the manual section.



Any recommendations on where I go from here?



Thanks



Mike

So what did they recommend?



2) "Any recommendations on where I go from here?"



a) Why not go with flat nylon washers instead  of the Belleville washers for 

your bearing preload?



b) You may be able to obtain washers of the exact dimensions needed from on 

line sources such as



http://www.mcmaster.com/#nylon-flat-washers/=130xnsi



or from a good hardware store.



c) If none of those sources work for you it is possible to buy nylon sheet 

in various thicknesses:



http://www.mcmaster.com/#standard-nylon-sheets/=130xra3



and with clever use of hole saws and a drill press create just about any 

washer ID and OD that

you need.



Please let me know if you have any questions.

Hello OC,



This is the reply that I received from Matco, thanks for you help.



I am not aware of Bellville springs for the axle ever being part of 

MATCO

mfg wheels.  It was likely something that the HIS folks used.  The idea 

is

to have preload on the bearings which is reqyired.  I'm not sure how 

well

that will work.



We have an axle, used on VANS aircraft, that provides the preload and 

the

column support of the fork separately.  It is shown at:

http://www.matcomfg.com/SPACERAXLE24KIT-idv-3681-44.html



This is for a 1.25 inch wheel but it gives you the idea.

Mike,

Also be careful with the direction of  bolt/axle  for the the wheel..

It can go from the left to right or it can go the other way.. 

Depending on direction of the bolt it can tighten or loose the bearings in case of jam in one or both of the bearings.

If it tightens it will immobilize the wheel and break back the front gear leg.

Impossible?  It happened to my while taxing.. Resulted in broken front gear leg and broken propeller.

If it happened while landing or on take off  it  would be far worse.

Jerzy
