I need to change the mains on a 66' K model later this week.
Anyone know if there is a jack point or if this can only be done with a jack pad placed under the gear leg?
 
I've used a couple of types of jackpads. Both are shop-made. One is a plate with welded-on flanges down two sides, shaped to the taper of the gear leg below the step. Line it with heavy tape or thin rubber to prevent scratching the leg. A short spud welded to the underside, at an angle that will have it vertical when it's on the leg, is the jackpoint. Tape a big red flag to it. It wedges itself on there pretty hard and can be overlooked when you're done.

The other was a larger affair that was curved and shaped to fit in the "armpit" under the leg at the fuselage. Not quite as handy and needed more lift to get the wheel off. It let the leg flex down as the jack went up.

This is from the '63-'68 100 series manual.

The manual recommends against jacking one side using the wing pads. Slippage and damage is likely. The "universal jack point" is the one I described first. Easy enough to make if you can cut and weld steel.
 
You would not regret having a wooden block made up of 2 x 6 with you to

lower axle onto once wheel is removed.

Particularly if you are outside and aircraft are taxiing.

Some boaters are aware of their wake and damage.

Many pilots are not.


There is another hidden danger that could cause a LOT of excitement.

If tanks are near Full and and Fuel Selector is in BOTH you have made a sort of

Water ( er fuel ) Level.

Fuel will run from the higher tank, through the Selector and completely

fill the lower tank.

This does a really good job of checking the condition of the top of the bladder

and how effective is the seal to the skin.

If it is not a good seal fuel will run down the outside of the bladder

and show up in the Wing Root area.

Often this is mistaken for a leaking Quick Drain.

Fuel may also drain from the Vent behind the Strut.

This can be HAZARDOUS.

There was a Cessna (?) Service Bulletin, Letter or Instruction outlining.

the procedure.

To prevent the cross feeding you use the same technique that Cessna

states as when parking on a hill.

Turn the Fuel Selector to LEFT or RIGHT.

Not OFF or BOTH.
 
On many Fuel Selectors; not all, there are t shaped passages drilled.

In ON , the through drilled passage connects Left and Right while the short passage

goes to the engine.

When in OFF the Fuel selector has been turned 180 degrees.

Through passage still connects Left and Right but short passage does not line up

with a port.

Some Fuel Selector valves use valves and cams but the result is often the same.

I’ve often considered how much av-gas is wasted by not using the Cessna

instructions.

Also how much asphalt was destroyed.

Sorry but no intent to hijack.

Just wanted to mention some of the dangers involved with jacking

an aircraft.

There are a lot more.

I don’t like working in a pool of fuel.

I have one of the "Jack Points" described by others in this thread - and it works fine. Don't know if it is the Cessna part or not - I bought it used.

Before I had it I would clamp wooden blocks onto the gear leg with a big C-Clamp - and apply the jack to the bottom block. That worked fine as well.
