I just got a 2800csa with a fresh long block on a stand. It needs the flywheel, plate, tc reassembled, also zeniths overhauled and front pulleys.

My manuals don't show it, but it looks like the plate and flywheel are bolted to the crank
first, then the tc is bolted to the plate. Is it so?

The slushbox was left in the car. Does the engine/tc then slide onto the input shaft?

I have 2 sets of tc's, flywheels, carbs. Apparently the previous owner had a parts engine.
How do I verify which tc is good?

I have the simple carb rebuild kit, without the accelerator pump. Can the pump be tested?
Also, is there something better than the 1-page scratchy diagram that comes with the kit?

Thanks,

To separate the engine from the trans, there are six (8?) bolts holding through the "flywheel" into the TC. You go in at the "window" at the back/bottom of the engine and remove/install the bolts one by one, rotating the engine between each removal.

Were it my job (and it has been) I would consider taking the engine and trans out as a unit, through the hood which will have to be removed and set aside. But then you'll need someplace to hang everything. The bolt removal above allows just the trans to come out under the car.

When you separate the TC from the flywheel, a quart of ATF may spill out, be prepared.

I don't know a way to verify a TC but ask a trans rebuilder.

If the present accel pump diaphragm is good by eyeball inspection, and the two carbs shoot equal amounts of fuel (check with a small cup in the venturi and ten pumps to average out the quantity) I'd clean the carbs, replace the gaskets, and give it a try. Too much messing with adjustment screws will lead you to trouble, if you're not real deep with how they work.

The Blue Books tell you how to remove, disassemble and clean, reassemble and adjust the Zeniths. There is also a BMW publication "The BMW Carburetor" which covers the Zeniths and the two-barrel Solexes used on 2002s. Also, IIRC Haynes and Clymer in their 3.0/Bavaria sedan manuals cover the process, but with poorer pictures.
