Frined needs help

[michael.warshaw]

SO MY FRINED HAS A 42 CHRYSLER WHICH HE IS TRYING TO GET RUNNING, HE NEEDS A SPECAIL TOOL TO TURN OVER THE MOTOR, DOES ANYONE KNOW WHAT HE CAN USE TO DO IT?

[Dodgeb4ya]

Didn't need glasses to read that reply. Goodness..... What a crank!

[BobT-47P15]

Looks like that damper sure enough has the ears for a crank.

Will just any old auto crank fit?

[T120]

..Note the position of the thumb on the hand that is used to crank in the photo

[BobT-47P15]

Would that perhaps be for in case the crank kicks back??

Avoid a broken thumb?

[RobertKB]

If the motor is free (loose) you should be able to grab the fan and turn the motor as I see it has the fan belt. Starter should turn it over as well. If those two things do not work the engine is likely stuck. There are many threads about stuck engines and possible solutions.

I asume the two holes in the cross member were for the radiator support but they also may have held a fitting that the crank handle went threw to help support the crank, with out that support it would be had to turn the crank.

My first choce would be to use a large 6 sided socket on that same fitting with a long extension and a flex bar. Pour some deisel on top of the cyclinders

to lube the rings. Pull the spark plugs

[TodFitch]

42 is a whole lot newer than my car. But that part of the engine and frame look pretty similar even though there are 9 years different and its a Chrysler and mine is a Plymouth.

Those two holes do look like the places the bolts that hold the radiator support go through.

The crank hole should be through the frame.

The nut on the crank looks like it is similar enough to mine that my crank handle would fit. If there is any chance the engine might fire (ignition on, gas in carb, etc.) you definitely want your thumb to be on the same side as your fingers. And you want to pull up on the crank rather than push down. Especially critical on a four banger with a manual spark lever like the Model A shown in the photo. Doing it differently will give a very high chance of serious injury (deaths were also reported in the old days) if the engine back fires when you try to start it. With a six equipped with automatic spark advance it is much less likely, but why take a chance?

But, as noted earlier, you should be able to turn it over using the fan blades. Especially if you remove the spark plugs.

[JerseyHarold]

If you can remove the inspection cover under the bell housing there are turning tools that grab the flywheel teeth so you can spin the engine.

[michael.warshaw]

where can he buy that tool?

[michael.warshaw]

if you look at the pic the part you won normally turn is a wierd style, kind of looks like counter clockwise half circles. what do you use to turn that?

[Dodgeb4ya]

If the starter won't turn it over (the fan) more than a 1" or 2-the way I'd check to see if the engine is seriously frozen then any hand crank or even the correct 1-13/16" /1-11/16" ect. socket will not work to get the engine turning. The starter and ring gear have the most reduction to turn the engine. If it's stuck, take it apart and repair it right. Might be water got in the cylinders causing the rings to be rusted to the cylinder walls and also rings are frozen in the ring lands or possiblya bad rod or main bearing. Valves also could be stuck in the guides.I have soaked an engine seized like this and got it running well but burned a lot of oil because of stuck rings. All of this is a call for some serious engine work.

As for using a hand crank in the special crank nut-1st off you need to find one, second you need to know how to use it, and 3rd youy won't have enough strengh to turn and start the engine if it was free!

Just find the correct size socket and use a breaker bar with it to turn the engine over.

[JerseyHarold]

I've seen the turning tools offered by several mail-order tool companies like Harbor Freight or JC Whitney, and they may be available locally at a good auto parts store.

[michael.warshaw]

mr b4ya thanks for your help, i would say your the most knowledgable guy on here.

[greg g]

Why did you and your frined both reject out of hand the notion that in 42 mopars were still equiped to be started with a hand crank????

Even the factory illustration from the brochure shows the fitment of the hand crank adapter.

[Young Ed]

Trucks were equiped with the crank start through at least 47.

[Cpt.Fred]

when i found the adapter on my P10, i was surprised, too.

i still haven't really understood how to get the crank (sadly i don't own one)

through the front sheet metal and radiator to the pulley.

i always thought i would be some kind of a remainder of earlier times

and they just didn't change that part on the 201 engine... now i see

it existed even longer.

anyone here ever tried that?

as for the thumb of the gentleman in the photo...

he sure was a wise man:rolleyes:

[greg g]

Left over parts.....Use em till they're gone.

[Merle Coggins]

My '50 truck has the crank start pulley bolt and there is also a hole in the front sheet metal for the crank to go through.

[MarkAubuchon]

Be careful starting it, your frined could end up fried

[JIPJOBXX]

Maybe you could use this guy to help start your car?????????????

[desoto1939]

I have a 39 Desoto and have two NOS front end nose pieces as spare parts.

Both are original MoPar parts and not aftermarket. One does not have the crank hole and the other one has the crak hole and it also has the crankhole cover.

The problem is that you can not use a crank to turn over the engine. The radiator sit so low that the crank can not connect ot he lowere pulley that you see on the pictures.

This is just a leftover formthe earlier cars and since we now have electric starters is was a thing of the past.

Yes when using a crank to start a car never and I again say never wrap your thumb over the top of the crank handle. The thumb will get broken you need to have an open handed grip.

Big question is who invented the electric starter and on which car was it first used on? I will give a hit there is a major hospital in NYC and the name of the hospital is part of the inventor of the electric starter. Answere below do not peek

Answer: Dr Kettering and it was used on the Cadallacs. Sloan Kettering Hospital.

My 1947 Chrysler 251 engine, has the crank ears on the damper pulley too.......Fred

[JerseyHarold]

I saw the crankshaft nut with ears referred to as a 'starting jaw' in one of my Mopar parts books.
