Engine Stripping
« on: December 08, 2007, 10:20:37 AM »
I had a few 36hp motors I stripped down for parts because they were way beyond salvagable. They required some rather primative means (hammer, crowbar, hacksaw etc...) to strip down.


However, I do have one motor that I would like to save, but like the others it seems to be \"fused\" together. I am currently down to the heads but unable to safely remove them. Any advice on how to strip down such  motor? By the way the WD option won't work.

Thanks.

Can you take out the spark plugs off and turn the crank?
You may have to use someones help to take it apart.

Thanks for the advice.

Unfortunately, I cannot turn the crank. I think this motor was either seized or sitting for a long time. I think I might try filling the engine and cyclinders with oil. This may free it up. But I have still have the problem of removing the heads in reasonable condition.

I may cut the case studs?

If you have extra rods then a sawzall right through the barrels is a slow, tedious option.

I've gotten aero engines apart by using a portapower pump adapted into a spark plug hole, messy but effective.

Consider renting a tiger torch (big propane torch for roofing), heat is your friend and cooking the s**t out of it a few times may loosen them up.

Try heating the cylinders and heads with a heating gun or hair dryer.  :ph34r:

You could also use cold and hot to see if it helps. ;)

If you are going to tap on it use wood or rubber so that you don't break it. [_[

Be carefull with fire/torch, magnesium will lite up you life in a heart bit. :blush:

It is common for the cylinders to get stuck in the heads.  Once you have the rockers off and all the head nuts, you should be able to pull the head off with the cylinders still in it, leaving the pistons hanging.  If you don't want to save the cylinders, a BFH will reduce them to scrap metal, leaving you the heads.

Thanks everyone for their advice. My strategy will be to try to loosen up the motor first, either by filling the cyclinders with oil or WD 40. This may allow me to pull the heads and cyclinders as a unit, because I cannot currently do it. The BFH and torch will only be used once I exhausted all other means or get totally pissed off.

Thanks!!

carefull with the torch if your cylinders are filled with wd40....

 ;)

ftr, i am a firm believer that wd40 is good for 2 things only.....water displacement (wd) and starting fires.

if you want a good penetrating fluid use liquid wrench or pb blaster.

good question.

my old man gave me a can to use once a long time ago & it worked wonders but i havent seen it since. that's why i mentioned liquid wrench. just as good and can be had at any local parts store.

Go with the diesel.  Fill the cylinders and let them sit for a few days, it works like a damn.  A friend of mine and I got the 327 Chev in his 49 Ford running after sitting for 25 years doing this.  It was seized solid so we filled the cylinders, let it sit for a week, went back with a breaker bar and voila!  She broke free and now runs like a top.

Maybe compressed air down the spark plug holes?

if a port-a-power isn't available you can use a grease gun.braze/silver solder a grease fitting to the threaded part of a broken spark plug,tip engine plug-hole up,fill cylinder with oil,getting ALL the air out,screw in fitting and start pumping.if piston is siezed this should pop the head loose(grease gun makes BIG pressure...immovable object;unstoppable force;something has to give)good luck...mike
