Hi.
New on here and looking for advice. Ive got a split with a type 3 auto box and 2.0 type 4 engine.Ive removed the engine and the Torque Convertor is attached. Two things how do I remove the TC and secondly ive heard to replace the TC back on the shaft in the bell housing prior to refitting the engine though im not sure how I would then bolt the TC back on? Really hoping for help..thanks a lot. Darren .

TQ is bolted to the flex plate which is bolted to the crank. When separating the engine from the transmission you have drawn the TQ off the splines of the turbine shaft and pump shaft.

Genuine auto engines have the case cut away to enable the flex plate to be bolted/unbolted to the TQ. My experience of fitting the TQ onto the pump/turbine shaft is to slide this carefully into position with the transmission in the car and then fit the engine as normal. Then reconnect the TQ to the flexplate with three M8 bolts/washers through the opening in the case.

I would not want to take the risk of bending the pump shaft or not getting the TQ seated properly on the splines by refitting the engine to the transmission in the car with the TQ already bolted to the flex plate. It may be possible to do this if both engine and transmission are fitted together when aligned on a bench and the whole assembly then fitted to the car.

Since you obviously have an unconventional/non original installation in a T2 split, I don't think I can add much else!

Hi Mark
Thanks for the reply. I understand what you are saying do thanks. Im hoping its not the end of the world and a learning curve for myself. My intention is to place the TQ back onto the shafts in the bell housing. Once the engine is ready I offer that in place and bolt the engine up and then fasten the 3 bolts up on the TQ through the opening ?
Regards

Correct. Just make sure the TQ is properly seated on the shafts and does not slip off them before you get the engine back in. Might be worth checking that the shafts are straight before you do and did not suffer any ill effects during the extraction process!

Hi Mark.

Im quite happy with how the engine came out..I supported the gearbox prior to pulling the engine out on a jack on a level surface. There were drops or sudden movements between the engine and box. The TQ is a serviceable part so Im thinking that at some point they can be removed from the bell housing. My last question is though....can you tell when the TQ is "home" ? Regards and thanks again

The should read there were NO drops. Thanks

you leave the TQ on the box and support it with a small bracket as in the pic below, this prevents it falling out and damaging the pump drive etc..

Hi..thanks for that..however when you remove the TC how do you know when its in place when you replace it ? Regards

it simply in place when all 3 bolts are bolted to the flexi plate on the engine.

I've edited my 1st post as I meant to say leave it on box not flex plate! sorry for the confusion!

Difficult to describe but if you get used to withdrawing the shafts from the box and see how they fit into the TQ and then fitting them back into the box you can feel when the splines are engaged and should be able to turn them by hand and feel resistance. With the shafts fully in the box you can slide the TQ on and make sure it's fully home and can be rotated.

It will appear to sit a bit further into the bell housing and will be drawn back slightly to meet the flex plate when you bolt them together.
