Dropping a 2 Litre Bus Engine
Bookwus - August 10th, 2009 at 01:33 PM

Hiya All,

I've had a bunch of experience dropping Type 1 engines out of Early Baywindow Busses. But recently I was asked to help with dropping a 2 Litre engine out of a 76 Baywindow Bus.

We got all the electrical and vacuum connections undone. Got off the air filter and AFM. Undid the rear mounting bar. Supported the engine with an ATV jack. Undid the engine to tranny bolts.

Gave the engine a pull backwards and it slipped out of the tranny easily.

This is where we ran into problems. We could not pull the engine back far enough to clear the transmission mainshaft. The oil filler tube would not allow us to move the engine back any further.

So.......how did we screw up? Or is there something we missed? Some trick we don't know about?

I'm appreciating any advice you can give on this little pickle.

just finished dropping a 1800 and a 2lit the trick is to remove the coil and the oil filler and the tinware front left side you will get it out not doing this but a lot of damage will happen oh and the fan grill after you have them off the engine comes out with a slight down ward attatude and remove the carby and dizzy cap than put rag or something into any hole
good luck

On a late bus you need to disconnect the gearshift coupling, take out the gearbox mounting bolts above the bellhousing, and lower the engine/gearbox as one. When its lowered to clear the rear apron, then pull the engine off the box.

Yep I have done it a couple of times in the past, and undoing the two bolts above the transmission and coupling to drop the whole lot, it then lets the engine slide off the transmission.

In view of what we ran into (the mainshaft not clearing because the oil filler tube ran into the rear apron and blocked any further movement of the engine rearward) dropping the engine and the transmission as a unit makes sense.

Thanks for the tip!

And one further question.............

When one drops both the transmission and the engine as a unit, about where is the balance point for the engine/tranny assembly? I'm wanting to know where to put that jack so the engine/tranny doesn't fall off.

quick question does the gearbox use the axles as support

amazeer - August 11th, 2009 at 09:03 PM

You put the jack in the same place as you would just supporting the engine. Its round about the sump plate, but not exactly. Cant remember if its slightly rearward or slightly in front. Sorry. If you have someone to help you, it will be easy to balance it if you go exactly on the sump plate.

Yep, the axles will hold the gearbox. Thats all I ever did. I guess technically if you put a jack under the gearbox it would be kinder on a CV. Just an ordinary scissor jack will be fine.
