Changing the nose gear "NG6" bushings on a VE

[Tom]

Hi folks,

My winter project this year is to replace the worn out trunion bushings on my nose gear,  (the bronze bushings in NG6)

Anyone have any tips or pointers?

Also, what can anyone tell me about the kit sold here:

http://www.eznoselift.com/ng-6.html  (this is the bearing NG6 replacement)

Thanks

buy it, its the easiest way to go.

You'll need to drill a hole through the outside skin that lines up with the pivot bolt, (the bolt that holds the nose gear to NG6).

When you take the nut off, slide the bolt out through the hole and the nose gear will fall off.

Swap out the NG6s and put it all back together.

Tom,
If you have the money go ahead and do what Waiter says...buy it.  It is certainly a better system than the brass bushings.  I personally feel that the bushings are the way to go.  Easy to change and WAY cheap.   I have changed the sets on all my EZs.  Two Vari s and now my Long.  No big deal, you can almost push them out by hand.  I think I'm going to have 12 bucks in the repair.  But like I said, if you don't mind the expense, a Jack Wilhelmson mod is way cool.

Hi

I did post this before, but I guess it was lost with everything else.

There have been some posts on this subject.

I had a Long-Ez, which had nose leg play, when I built my current
aircraft I did the following, which has proved successful.


I hope this helps.

A method to eliminate side play in the Nose Gear strut and NG6
Casting.

After some time in operation the standard Oilite bearings in the NG6
casting can develop play which can affect accurate steering.

For new build aircraft a larger casting with taper roller bearings
can be obtained and fitted. This fix requires removal of the NG6
casting on existing aircraft.

For aircraft owners who do not wish to remove the NG6 casting from
the Nose Leg the following procedure may be used.

Remove the nose gear strut and push out the NG 23 Oilite Bearings.

At a local machine shop, have the NG 23 Bore, Reamed to 0.6875" and
the casting sides Spot Faced to 1.000" to clean up normal to the
bore.

A good machine shop should be able to achieve this at nominal cost,
without causing any damage to the nose gear leg or NG6 Casting.

The following Parts need to be obtained:

- Nose Gear Pivot Bearings

- Torrington Drawn Cup Full Complement Needle Roller Bearing,

2 Required, Part No B-810 0.500" ID. 0.6875 OD. 0.625" Wide, or
similar.

The NG7 Pivot has been used without modification but for long term
operation the following should be done:

- The Nose Gear NG7 Pivot should be hardened to 58 HRC and a small
spacer made, 0.500" ID. 0.625 OD. length to suite, to keep the
bearings positioned.

If getting the NG7 hardened is difficult it is also possible to use
the Torrington Inner Ring Part No IRA-5 with the B-88 Bearing and
machine spacers to suite.

Nose Gear Thrust Bearings and Washers:

- Torrington Thrust Roller and Cage.

2 required, Part No NTA815.

- Small Thrust washer Part No TRA 815-0.030".

- Medium Thrust Washer Part No TRB 815-0.060".

- Large Thrust Washer Part No TRC 815-0.092".

You will need to buy some of each thrust washer because it is
difficult to determine what thickness or stack you'll need until you
have several washers to use.

Assemble the parts, install the Pivot Bearings into the NG6
separated by the spacer and use the Hardened Thrust Washers each
side of the Thrust Bearings. Use additional washers to eliminate
play and centralise the Gear Leg. An `O' Ring can be used around the
Thrust Bearing as a grease seal.

The Bearings can be obtained from the following or your local
Torrington supplier.
