Separate 727 from Frozen Engine

[Sam69sat]

Any tricks to separate a 727 from a frozen small block? Thanks

Undo the bellhousing bolts and pull it off.

Just be prepared for a mess.

Thanks. Wasn't sure because i always see people unbolting the flex plate from the torque converter first.

Only when they can turn the engine over.

When you unbolt bellhousing support the tailshaft. You can probably undo TQ by rotating trans. If your going to use the trans I'd replace the front pump bushing not hard with SM. It will probably be damaged. Guys that pulled engine on my Satellite left converter on engine and I had to pull trans shortly after getting car running to fix it.

The torque converter will still be attached to the seized crank. When I've done it I cut the flex plate bolt heads off with a torch.

With trans unbolted from engine won't rotating the trans 90*then another 90* etc allow you to remove TQ bolts? No red wrench.

No, the converter bolts to the flex plate between the converter and the block. The crank is seized and will not rotate. you may get at one or two.

Fran is suggesting removing motor to trans bolts and rotating the trans 90deg at a time to remove flex plate bolts. Only problem I see are the locating dowels...

Explain to me how rotating the trans will change the converter to block relationship? It won't. The converter is attached to the crank. The crank is seized. The bolts are between the converter and the block.

If you just need the trans and don't plan to do anything with the engine, then you could just call the converter a loss and leave it on there.

 

[Fran Blacker]

My thought was as you rotate trans the splash shield area would allow you to get at TQ bolts? May not work as Doug pointed out. Just thought to give it a try. Replacing pump bushing isn't a big deal.

Yep, you're right. The cover plate opening is covered over still by the block when trans is rotated in any other position...

Pull the engine from the trans with the torque converter still bolted to the flex plate. Once separated, all 4 converter bolts can be reached with a combo wrench without needing to rotate the crankshaft.

As mentioned, you need to pull the converter attached to the flexplate if you can't get to the converter bolts.
It might be easiest to pull engine and transmission out of the car as a unit and unbolt them out of the vehicle.
Done it in the car before when a cast crank stroker broke the crank in two, and I wouldn't try that again. It took more time and brute force and risk damage to converter and transmission.
