Re: Model A motor froze-up
 

Thanks Rusty. I'm not giving up yet.

Re: Model A motor froze-up
 

Thanks, Bob, I'll check the MARC online.

Re: Model A motor froze-up
 

Okay, I'll keep twisting, turning, rocking, squirting and pouring. Instead of shopping for a new purse, I'm going shopping for a good set of wrenches. :)

Re: Model A motor froze-up
 

Betsey, I've been thinking about your car and I'd like to know if it will roll without the engine. Can you hook it up behind something and pull it? At least out of the shed/barn in neutral? Will it roll? I think I want to confirm that something else isn't stuck. Was the Emergency brake on for all that time? I think I would hitch it to a big lawn tractor or a truck and yank it out of there just to make sure the brakes aren't seized or something else. Terry
PS don't pour any more MMO into the engine, it's got enough!

Re: Model A motor froze-up
 

Thank you, Terry.
It does roll in neutral. The motor is full of MMO. The emergency brake is not on. The brakes are fine.

I'm still rocking it.

Re: Model A motor froze-up
 

I've enjoyed reading your post Betsy.
I am going through the same thing currently. I have freed several engines in the past and it was a piece of cake. The model A engine I am now trying to unfreeze is in the same predicament as yours. Have always had great success with ATF-not this time. Mixed it down with gas to thin it and nodda. Today I tried the boiling coke trick and nodda. Even pulled it slowly around the yard with my pu-nodda.
My next move is to empty the pan, and overfill with diesel as Bill suggests. Then I think I will take a nap for about a month and give it a go again.
Never had one this stubborn, but going to beat it. So don't give up and give it plenty of time....

Re: Model A motor froze-up
 

Betsey, I assume you've been rocking back, in third gear? Try putting it in reverse. The idea being to turn the engine in the opposite direction. See if you can get a little motion out of the fan turning it backwards.

Re: Model A motor froze-up
 

By rocking the car in high gear you get the most leverage, and by rocking back and forth the crank is forced to move both directions. Low or reverse will give the crankshaft very little force.

Re: Model A motor froze-up
 

Thank you, Ronn, for your encouragement. Sorry to hear you, too, are having a stubborn motor to "unfreeze." I'll keep trying. Patience and persistence. Please report when yours comes free.

Re: Model A motor froze-up
 

Yes, Terry, I have been rocking it in third gear. So far, all that's happening is I get a lot of slosh coming from the gas tank. I'm wondering what's happening in there. I'm supposing I should remove that gas, perhaps even the gas tank to clean it out.

Okay, I'm getting away from where I need to be - the motor unlock. I think, for a change, I will put it in reverse. I'm trying everything suggested - short of sending it over a steep hill with a push. (That was meant to be a joke, only.) I'm afraid to pull it in gear. I don't want to hurt something else that might be stuck as well.

So, I'm rockin and a rollin. Sounds like something from the 50s. :)

Re: Model A motor froze-up
 

Is the fan belt tight and when rocking it in 3rd gear is there any movement of the fan blade?

PS Also when moving my car it's easier to grab a tire at the 10 O'clock and 2 O'clock position and use that position for the rocking grip.

Re: Model A motor froze-up
 

Tom is correct, reverse is too low a gear-keep it in 3rd.

Re: Model A motor froze-up
 

Betsy,
I REPEAT, keep the cylinders & crankcase filled to OVERFLOWING with diesel & let'er soak for weeks! Bill W.

Re: Model A motor froze-up
 

Yes, Ross, the fan belt is tight as well. It does, however give a slight back and forth motion along with the crank when I rock Betsy back and forth. Also, for the rocking motion, I am able to grasp the spare tire holder by the left door with my right hand and grasp the headlight/horn post with my left hand and rock quite briskly. The crank gives a clunk-clunk sound as it jerks with the movement. One positive note: I'm developming a good grip in my hands with this constant activity.

Re: Model A motor froze-up
 

Bill, there seems to be an overflow with only one of the spark plug holes. Should I put in more? If I thought it would help, I'd drain the MMO, put in the ATF/acetone solution, and give that mixture a try. What say you?

Re: Model A motor froze-up
 

If you are getting some movement then that's encouraging. It should continue to get increased movement as rocking progresses.

Re: Model A motor froze-up
 

Bill, sounds like you need to make a "house call". LOL

Re: Model A motor froze-up
 

I am in Bismarck, and have 6 Model As. I also have built one of the tools that Tom describes. I may be able to come to Harvey sometime soon if you wish.
