 |
|
my 67 fasty
its got a universal case engine
was Frozen...?
took heads off and thought i got it loose
which i did
put it back to gether and same thing!
Can Not turn by hand or screw driver pry...
i have taken off heads, piston heads, barrels
And STILL Hard to turn
all parts look Brand New
No particals in the oil...
i have looked inside and everything Is Super Clean!!
i dont get it
with it in the car its tough enough that i can get the fan bolt loose
out of the car i have to hold on to it Hard and turn it
i get maybe an inch of easy back and forth movement
BUT then....
should i just put my good starter in it and try to crank it over???

spun?
like one on top of each other?
wouldnt that mean a loose rod or worn crank?
engine is short block, no piston heads
and i can move the rods freely
my thought was a tight fan? maybe an main bearing

it could well be that the main bearings are misaligned (usually caused by overheating)
I had an engine like that. when i tried to torque the main case bolts the crank would get tight at some spots. it can be fixed by line boring the case but my case was cracked so i just put less torque on them and built the engine. (i'm not recommending this) but i thought i would do an experiment.
i recently took that engine apart after 5000+miles and all seemed well... actually the main bearing bolts were quite tight.
i would split the case and have a good measure around. |

With the heads, pistons and cylinders off, can you still spin the engine over easily? It should. If not, then you need to split the case and find out why. It's possible that the dowels aren't in the correct spot with the main bearings (wouldn't be the first time that happened).

Is the distributor in? If not, the drive gear will pop out and bind on the crank.
Have you checked the end play? |

...This might be a "duh" moment here but... are you sure the oil slinger on the snout of the crank is facing the right direction? If this is facing the wrong way... it will cause all of the above and it's the easiest to overlook (good news: this is the least catastrophic of problems you may have.  bad news: you still have to split the case to correct it  ).
I haven't heard anyone mention this yet so I figured I'd throw it out there. Good luck!
The slinger is the big washer-looking thing about an inch behind the crank pulley bolt. Please note that it is dished towards the bolt. If dished towards the flywheel end of the crank, it will lock up the engine. The engine CAN be assembled this way although you'd have to be determined to do things wrong cuz it will fight you.

With the heads and pistons off it should turn effortlessly.
If not the bottom end needs to be rebuilt...
...or you can use it as a boat anchor.

| Also if the engine got over heated the case might have warped and needs align boring. I agree with josh, it should spin effortlessly, case needs to be split |
i mentioned this earlier but seems to have been ignored.
splitting the case requires nothing fancy. just a 13mm and it memory serves me correctly a 17mm socket. if all you want to do is get it to turn over just back off the 6 main bearing nuts a bit and it will free up.
if you have torn it down to the short block then you may as well keep going. |

Shark you need to split the case, that engine will implode in a very short amount of time if you try to run it that way, split the case and find out whats wrong , by some permatex aircraft sealant for reassembly if things can be put back together.. or find another short block in good shape... but you aint going to far if you run it like that bro!

it won't run at all... if you can't turn it over with a wrench, it will never spin over enough to start...

| Someone might have pinched the main bearings with the dowel pin causing it to be tight. If it was pinched main bearing will need replacing. Also bad bore will cause it even with new bearings. |
