Yep.

1447095 2018-03-11 07:10:00 A deep socket to reach into the harmonic balancer, then a long breaker bar to the underside of the right side of the frame.

Hit the starter.

The balancer bolt walks out with every revolution. Keep fingers and arms and legs outta the way.

Do they all undo in their direction of rotation? I would have thought it would be opposite, I cant remember I just put a 3/4" rattle gun on them if they dont come undone I try the other way. I once had to put nylon rope down the injector hole on one and use a 6 ft length of water water pipe I thought something was going to break first but it come undone thank****.

Where the engineer could hear that his wife' car's timing was a bit out.

Yes it was Castrol!

I wouldn't use that old nylon rope trick any more these days. Pistons are eggshells of the old versions and the angle on impact on the rod makes the piston pin need to be offset by a few thousanths that might make the torque on the piston/rod unacceptable if you get more pressure on one side or the other.

If you carefully have the breaker bar up against the frame and hit the starter, the direction of rotation of the crank bolt will make it spin out of the threads.

I have never seen any engines use a backward turning crank bolt - they always try to 'tighten' themselves in normal rotation and if the socket is held firmly enough (that's the pivotal word there - 'enough') then it will unscrew itself when the starter is engaged.

There are likely to be a few exceptions in Brit Econo-Boxes though.

Your job is to find the way to re-install it afterward!

They undo themselves when held and the crankshaft rotates around them. From front view - all engines --- barring a Limey Locomotive or so - rotate clockwise.

That's the way it's been except for an occasional Saab*... like the old model 96 in 1969, that used the Ford Commercial/Industrial Taunus engine make in Merrie Olde England.... backwards rotation ---- love it!

Sometimes I think the Brits cannot find their own rear end with a map and a flashlight! No offense - present company excepted.

I am a bit confused you say they always try to tighten in the DOR of the crankbolt. We want to loosen said item.

1447099 2018-03-12 05:21:00 You don't need to be an engineer to hear it. hell, I could.
And everyone in the car with us, including GD.
Whats that noise nana?

1447100 2018-03-12 06:15:00 Think about it .

Tightening the crank bolt one turns it clockwise, in the same direction as the engine spins when running .

If one holds the crank bolt with a socket and at least a 36 inch breaker bar then turns the starter, it will unscrew the bolt .

I always put the breaker bar handle very close to the frame area that is to be used to stop it from moving . The impact of the bar hitting the frame will shock the crankshaft bolt loose .

You might have to repeat it another time or two . It WILL work .

1447101 2018-03-12 07:28:00 Its amazing the things my dad had to do on his cars that we don't now
Adjust the timing
Bleed the brakes
Adjust the spark plug gaps
Grease all the nipples
Put water in the radiator

The list could go on

Corrected that.

1447102 2018-03-12 20:46:00 In this YT Vid ( . youtube . com/watch?v=Kvfko3kp-zg" target="_blank">www . youtube . com) Dave says to use acetylene gas, to heat up the crank bolt, not propane . I'm sure I have used butane (I think) on crank bolts, axle nuts, tie rod nuts, etc which seems to help for loosening .

For timing, if auto adjusted, won't something be lost? like loss of mileage . To keep timing stable, more fuel may need be injected - higher trim; and/or earlier spark ignition/propagation resulting in reduced spark plug life span . Which may mean more potential for nitrogen oxides/hydro carbons fouling up the egr valve/O2 sensor . So using iridium/platinum plugs may help reduce life span .

So for example, the driver may never know of a increase in fuel consumption, or some other issue that may occur, as a result of timing being auto reset beyond normal settings .
