New shock discs

[bixmooney]

My prior post about emergency gear extension got deleted, but all is working now and I ended up putting an actuator from a J model in my F and the dual relays , new downlock and squat switches and rerigged and working well. 
 

i decided to do the shock discs , even though they were not terribly old, 2012.   Happy I did that , and fyi, anyone thinking of doing those or waiting, taxi is noticeably smoother for me.  

3 hrs mechanic time for the shock discs and I felt like it was well worth it.

One hour per wheel?  Someone must have.. been there done that and knew what they were doing?

3.5 hrs now that I look.   Pretty darn quick !   It helped me decide to do it, when he said he has done a lot of them and that is about the time he needs.  
$1955.25 for 11 discs   Happy it is done

Curious where you got them done at?

Awesome thank you! Been thinking it’s getting close to time, my local A&P said he’s not the biggest fan of doing them. So thinking about having somewhere else knock it out. We did the nose gear pucks about a year ago as we were replacing the truss due to damage anyway.

I've been told the main gear pucks can be replaced using the weight of the plane to press everything back into place, if those are all that you're changing out.

[cliffy]

Yes you can change the mains by jacking the airplane and lowering it on to the new pucks

You may need someone to lay on the wing tip (with the wheel on the ground) to help get just that last bit of squish to get the cross bolt in. 

Just be sure you assemble it correctly

Probably helps to have full tanks and some friends in the cabin.

Friends in the cabin and full tanks may help, but recently my mechanic and I did my nose wheel shock discs.  We used a ratcheting strap between the upper and lower halves, which generates way more force than a couple of 200lb’ers in the cabin.

The nosewheel is usually the hard one.   Glad to hear that the ratchet strap worked in your case.   I know some have had no luck trying that.

I was able to use the ratchet strap to get the nose wheel apart, but the get the collar bolt back in I had to go to the bottle jack, modeled after others here on MooneySpace.
