emealer1 Posted February 16, 2014 Share Posted February 16, 2014 Well I got Bertha out and had someone pull me down the road just to see if she'd turn over. The transmission was fine but wouldn't turn the motor, the clutch just started smoking. The last year she was registered was 1981 so it's really not surprising but I do know she was running when parked. She was actually inside at first and someone using the building decided to drag all of my grandads stuff outside thus the broken windows and extra rust. What's the best way to try and break the old 673 loose? Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted February 16, 2014 Share Posted February 16, 2014 I'd say remove the injectors and fill cyls. with solvent/diesel/atf mix, check daily for about three days then re try Quote Link to comment Share on other sites More sharing options...
Mike Posted February 16, 2014 Share Posted February 16, 2014 I would have used a breaker bar instead of pulling it off. After filling the cylinders use a bar in about 2 weeks. You will be glad with that method. Regardsmike Quote Link to comment Share on other sites More sharing options...

emealer1 Posted February 16, 2014 Author Share Posted February 16, 2014 Use a breaker bar on the crank pulley or what? I'm also going to check the tanks, filters, governor, pump, and intake before trying again in hopes of cranking next time. I'm going to pull the injectors and fill the cylinders with the acetone/ATF mixture. Think adding penetrating oil to the mixture would help?

Superdog Posted February 16, 2014 Share Posted February 16, 2014 Breaker bar on the crank pully,or what I like to do is jack up the back end and leave it in gear,then you can rock the wheel back and forth. 1 Quote Link to comment Share on other sites More sharing options...
mack mhe9 Posted February 16, 2014 Share Posted February 16, 2014 I know there are more experienced people on here that will give better advice. My take would be really check it out if its been sitting this long, hydro locked, stuck pump, sludge or junk in the pan, if it starts be prepared if it runs away. Most likely you will not have these problems just be careful. Quote Link to comment Share on other sites More sharing options...
rsb502 Posted February 16, 2014 Share Posted February 16, 2014 No acetone in the engine it breaks oil down it doesn't add lubricity.

bullhusk Posted February 17, 2014 Share Posted February 17, 2014 I use ATF and blaster 50/50 it has never let me down... use mystery oil if u can't get ATFBULLHUSK Quote Link to comment Share on other sites More sharing options...
Brocky Posted February 17, 2014 Share Posted February 17, 2014 Another trick is to put a bottle jack under the breaker bar and add some truck weight to it and leave it sit that way as the solvent mixture in the cylinders works. 1 Quote Brocky Link to comment Share on other sites More sharing options...
emealer1 Posted February 17, 2014 Author Share Posted February 17, 2014 Are the injectors held only by the studs with nuts or is there something else too? I haven't started anything yet. I'm trying to wait on my manuals to get here. Quote Link to comment Share on other sites More sharing options...
MACKS Posted February 18, 2014 Share Posted February 18, 2014 Are the injectors held only by the studs with nuts or is there something else too? I haven't started anything yet. I'm trying to wait on my manuals to get here. Yes use two small pry bars under the ears and see if they will pop out,if not you may need to use an injector puller.Forgot to say just remove the nuts from the studs there is nothing else holding them.

theakerstwo Posted February 18, 2014 Share Posted February 18, 2014 I would never tow a stuck engine in gear because that is the best way to bend rods I know of.Like been stated jack one wheel up and put in hi gear.If its a air shift ,shift to hi range.Then rock back and forth after soaking the cylinder with what ever.That is all the pressure you need to put on it.If that is a 673 there is a small hole in the bottom of the flywheel housing that you can put a screw driver on the ring gear teeth and get a lot of pressure on the flywheel also. 1 Quote glenn akers Link to comment Share on other sites More sharing options...
