How The Hell do you Get the Camlocks installed?

[Missile=Awesome]

So we lost one of the camlocks that secure the oil access cover.  How in God’s name do you get the damn thing installed?  I/we have replacement, but I am clueless...

Regale me with “the way” O’ Mooneyspace possessers of the knowledge.

I tried pushing one of the posts in to allow installation and went “Nope” that can’t be right...

What part went missing?

The hole or the core?

There are tools for both...

The core tool is a special pair of pliers...

The hole tool is more of a punch...

Either aren’t typical amu pricing for planes... but a pair of pliers for something you only use for five minutes...

The core tool is good to have... because they like to jump overboard every now and then...

Best regards,

The stud is removed or installed with the pliers that Anthony posted above.  The grommet is held in place with a small lock ring, you can remove it with a couple of small sharp common blade screwdrivers.

So you basically force the core through the hole with the pliars, eh?  I figured as much.  Ya, saw the tool.  O.K. $16 dollars for a five second exercise...Got it.

The pliers compress the spring in the stud, allowing you to remove the stud from the grommet.  You’ll be happy to know your spending doesn’t stop with the pliers, there is also a tool for reinstalling the snap ring on the grommet.

I just bit the bullet, bought all the tools and all the Camlocs needed to maintain the airplane. When one is needed I break out the "Camloc" kit and replace. Quick job when you have all the right stuff.

Also on my Ovation for the 2700 series around the stacks and the air scoop I went to Mil-Spec 2800 series with a thin washer underneath. Stronger, but the main thing is if you are in the field you can get your fingers around the edge sufficiently too compress the spring and extend the stud. No tool needed. They are not nice and "flush" as the 2700 but they look fine as the cowling is riddled with 4000 series exposed anyway.

They do? My C must be an aberration, I've not lost a one since purchase in mid-2007. There's 20 on the avionics access panel, and more than double that holding the three cowl pieces on.

I just wish it wasn't so foolishly expensive to exchange them all for phillips head . . . .

Has anyone used the retainer install tool in the video? It looks much easier than how I've seen them installed.  The part number seems to be 4002T02-1BP, but I can't find any for sale.

This was the video I was looking for.  Still not getting why compressing the spring allows it to go in easier.  The retaining washer is the key to keep from losing the screw.  What a pain in the ass...

Compressing the spring extends the shaft and thus the cross way beyond the body which allows you to angle it more to the panel and get the cross through the hole. After that it is done.

Frankly, I like the straight slot ones best, as you can see at a glance that they are all locked in place if all the slots are aligned.

When the pin is wider than the hole in the grommet the pliers allow you to angle the stud through the grommet.

You don’t need the washers to retain the studs on the large (4002) Camlocs because the T pins are larger than the hole and the spring keeps the stud straight in the bore. It’s very simple to insert or remove these studs with the pliers and almost impossible without them.

The small (2700) studs require a washer, but these can be assembled without a tool.

Some of the 4002 Camlocs on my cowling were either too tight or too loose after I replaced all the anti-chafe tape and I replaced five to get a good fit. Most are 4 or 5 with a few 6 and one 7. The length is marked on the head.
