Posted: Thu Jun 12, 2008 3:31 pm Post subject: aerocet 1100 amphib rigging

I bought a set of aerocet 1100 amphib floats, and am workinjg on the rigging before I actually try to install them.  I have gone through all the instructions and set everything up like they said to.  I built a platform to mount the johnson bar, double pully, etc.  With everything hooked up, I can cycle the gear up and down, and I think that I finally got all the timing correct.



My question is,  about how much force is normally required to retract the gear?  I have no idea what to expect, so I am concerned that I have something wrong, and may brake something.



If you fly aerocet 1100 amphibs, could you guess how many pounds of pull is required to do the retract.



Thanks,



Louie

Louie, Good work.  Make sure your gear is actually going over center on each wheel.  If there is any that are going over center early you could be getting more resistance

- Also if you cables are too tight you will get more resistance from each one -main and nose wheels cables all add up to be more resistance. 



When i got my 1100s all i got was the floats, struts ,spreader bars and the johnson bar and cables from floats. I made the bullwheel and all 4130 fittings that goes under the seat.  you need a good pull.......  how much ? well i would guess 50 to 80 pounds at the most. It helps to have your should belt on. 



I have most install info for the 1100s  scanned online if you need it let me know.



I plan on installing mine in hte nextd few weeks with time permitting. Lake season is nearly here but I am having a blast on the King fox tires right now.

Thanks for the response Dave.  



The only other thing that I am not sure about, when down, all four wheels lock down as they are supposed to, but when retracked, the mains lock over-centered as required, but the nose wheels don't seem to.  Should the nose wheels lock over-center when retracted, or are they held up by the cables alone?  If they need to lock over-center, I need to tweak on the adjustment some more.

Louis , I was not aware that Aerocets went over centre to lock up when gear is retracted ? Mine are held up by the control cables and the Johnson bar detent that locks them up.  When locked down the Johnson bar once again has a detent that holds the gear over centre and locked down.  You have to make sure that mains especially are over centre when the handle is locked in the detant. If not you will twist one of the parts inside and/or bend or shear off the bolts that go through it.

Dave,



There is an up lock also, at least for the mains.  The General description mentions it, and Step 30 of the installation instructions talks about it also.  I can get the mains to lock in the up position, but not the nose wheels.  That is why I asked.  I think that I am going to ASSume there is not an uplock for the nose wheels.

vet,  read again and study your gear. 



The Johnson bar holds your gear in the "locked  up" position .  There is NO over centre on the retract mode. So if your Johnson bar comes out of the detent when retracted then your gear will fall and /or sag. 



I got mine in shop today.  Have to repair the Left main gear. Fiberglass is cracked  at link tube.  I too abusive   hundreds of landings on grass runways  beats em up annually.
