Posted: Fri Jul 04, 2008 6:28 pm Post subject: Grove Main Gear Support

When I purchased my Grove main landing gear, I was told I needed main gear supports from Zenair in Canada, since they supply them to AMD.  Now that I'm at that point, I can't say that I understand how they mount.  Do they work in conjunction with Zenith 6-B-11-4 (welded main gear attachment) or replace it?  Does anyone have any drawings.  Picture attached. 



Thanks.

I'm not 100% sure but I believe it replaces the piece of aluminum angle that is used with the normal gear. Those welded on pieces allow for the smaller (front to rear width) gear.



The piece in the background goes on the bottom of the fuselage then the gear is sandwiched between it and the pieces in the foreground.



Is that clear as mud?

After posting my question, I basically figured out what you just described.  Now I just need to determine if the welded-on spacer goes toward the front or rear of the channel.  

  

 Thanks, Gig.

The rear, I would believe, based on the gear on my Zodiac being positioned

at the front of the channel.



I was going to take pictures this morning, but Gig described things just

fine.

Larry:



I had the same question when I went to install my Grove gear.  One thing

about this list, questions are sure answered fast!!



In addition to the answers you already have you can go to the AMD site and

look at the drawings (Do other manufacturers of light aircraft provide the

same excellent detailed info? i doubt it.)



for Grove gear:

for the standard Zenith gear:

Why do they supply a smaller main gear other than the one that Zenith supply. (any benefits one over the other)

weight!   The difference between the two is amazing.   I am away from my shop right now but if memory serves me correctly there is at least a 10lbs savings.

different alloy and temper - Grove material is stronger. Stronger/stiffer = less weight possible with smaller crossection.

Absolutely, Also a lot more prone to  corrosion,  something for those guys in coastal, high humidity, pollution  areas to consider.

and on the down side as well - also extremely notch sensitive as aluminums go.



Anyone using them should make inspections for nicks and gouges a preflight thing and treat them like a similar nick in a metal prop. Always dress them out in the long axis and avoid any sharp changes.

In addition to the comments others have posted, I'm told that the Grove gear

sits a bit higher than the Zenith gear. AMD also has theirs gundrilled, so

there are no external brake lines running down the gear legs (though there

are short lines from the bottom of the legs to the brake calipers).

The gun drilled brake lines is why I swapped my gear out for Grove.  Having the brake lines just "hang out back" spooked me.  My Kitfox had gundrilled Grove gear and it was fantastic.  I hope my XL is the same.

Has any body tried the Composite gear available from spruce?

I understand there is a 40 LBS savings to be had?

While I'll admit the gun-drilled brake lines are nice. The lack of them is hardly anything to be spooked about. Cessna has hung them out the back for years.

discussed a while back. The gear that was available from them last year was two piece - not sure how it could be used without a major re-engineering exercise.

I have it in my plane.  You do want to make sure you get the gear  before you get to that stage.  The gear attachment is different.  I  actually did not get mine from ACS.  It is from a CZAW plane that the owner  wanted to tear apart due to the accidents.  It was almost a new plane and a  very well built plane.  As far as the re-engineering goes, the gear channel  was the exact same as mine with the gear attachments being different.   There are 2 metal I beam type fittings that go inside the gear channel from the  bottom and 6 support pieces inside the fuse.  4 of them go along the sides  of the gear channel and 2 of them go on the inside of the center console and the  seat belts attach to them.  Makes the seat belt attachment so much  stronger.  I feel better with that.  There is a huge weight  savings with this gear.  It was not hard at all to convert to use this  gear.  I got the gear, wheels, tires, brakes and wheel pants for $150.00,  so I could not pass it up.  I am installing a Corvair on my airframe and I  just saved the extra weight from the Jabiru to the Corvair.  It is a 2  piece system, but it stands taller.  The wheels and tires are much lighter  than the grove gear and I thought it might be hard to find parts, but it is  not.  I have already ordered and received extra disk brakes rotors and  pads.  I am excited about the gear and hope that it was worth the  conversion.  I saw the gear on the original plane and it looked  really good.  I don't know what all comes with the ACS system, but  I got everything I needed from the donor plane.  I was  very impressed with the welded parts.  They were top notch  parts.
