Lost two days trying to fit the T9 gearbox with engine at maximum angle and lots of wobbly stacks of wood. Stupid.
Did some reading; how about centering your clutch plate first, yes, and put the gearbox in gear, so you can line up the splines…
My clutch center tool was a 10mm socket that just happened to have the right outer dimensions, I put a round headed bolt through it (filed a little less wide then the socket), and a piece of wire behind the nut, to be able to get the socket out again after tightening the pressure plate bolts.
Using a socket extension didn’t work, the socket would stay in there.
Ordered a $ 60.00 motorcycle scissor lift, mounted that on a cart, put the gearbox on top, and tied it to the lift with wire (why aren’t these boxes flat at the bottom?), to keep it from falling off.
Then I jacked the box up, and carted it more or less straight to the engine.
This time success, but still, this isn’t easy when you want to work alone, and the car is jacked up
only 14 inches from the floor. Space and equipment have their limits.
