Why should the torque convertor kept in place?
« on: April 16, 2012, 18:05:38 »
The Haynes manual says that it's important to keep torque convertor in place.
Why is that? I don't know if there's a seal behind the torque convertor, but if so i would like to replace it now the engine is out.
When i removed the engine the convertor came slightly forward and then felt back in place.
Is that a problem?
Who clear things up?
Thanks!

I think it means don't let it fall out of the housing while removing and and maneuvering the trans.

We use a piece of mechanics wire to keep them from falling out while they're not connected to the engine.

Thanks for the answers so far.
Is there a seal or a bearing or so behind the convertor that better should be replaced while the engine is out?

Yes, there is a seal behind the converter that fits on the primary pump housing.

When removing/refitting the torque converter, be mindful to lift it up (or reinsert) straight so as not to damage the lip of the seal.
You will find that there are two tabs on the rear of the converter that slots into reciprocal slots in the primary pump and these tabs could also be damaged.
The manual describes this procedure very well.

Hello Eminent,

You must have the converter tabs engaged and the converter fully back in place or the front transmission pump in the transmission will be ruined when you tighten up the engine and transmission.

During removal of the transmission, the converter is disconnected from the flywheel and left in the transmission during separation of the eng. and trans so that the bushing in the front transmission pump is not damaged.

You will find it in the BBB. Section 27-3 (pages 5 and 6) of the '59 Passenger Cars Manual.

Forget about Haynes, most of the procedures mentioned in there I take with a pinch of salt...  ;)
