Homemade adapter plate and R150f tranny

[1.9ZOOK]

Well the `ol G52 tranny just wasn't what it use to be after several years
of the "not quite right" adapter I made. I know it was over the allowed
runout.

So out with the G52 and in with an R150f (V6) and new 7/8" aluminum plate.
Started with plotting out all the holes that I found on the interwebs.
I clocked the tranny 3.5º towards the passenger side to allow more room for
the exhaust / starter.
Holes were plotted on a Mill with Digital readout.

The green angle plate represents the engine block.
The flywheel has been spaced the distance of the crankshaft.
The aluminum plate is 0.875 thick which gives 0.145 clearance.

I set the adapter up on a rotary table and have already cut the outside and am stating the inner circle.

Starter bolt holes and gear hole bored out .

Starter fit nicely.

Removed 0.550 ,that was too deep so made a shim .062 and that did the job.

Fitted to the ALH block, the engine dowel pins tapped in snug.

That G52 held up for quite a while. Nice looking work, curious if you can remove the oil pan while in the vehicle with that adaptor. Or is it a moot point because of driveline interference/

Thanx jmodge
The pan is pretty much locked in place, hopefully it adds a little more beef for the inconvenience of
dropping the pan some day.

Here is a comparison of the 4 cylinder and the 6 cylinder flywheels..
22RE-8 7/8"
3.0 V6-9 5/16"

I plugged the 8 stock bolt holes and redrilled the 6 to fit the ALH crank.

An adapter was made to use the stock V6 pilot bearing.

I shaved .165 off the crank so the bearing wouldn't bottom out on the output shaft.

Pilot bearing adapter installed.

Not sure if you knew this or not but the 3.4 and 3.0 v6 share the same crank bolt pattern, the 3.4 provides a little bigger clutch than the 3.0. I also used the 3.4 starter for a little more cranking rpms for those rare single digit temps in the southeast winters.

I do now......I found Jimbote's comment about machining the 3.0 flywheel to accept the 3.4 clutch and PP.
So that will be an upgrade in the future.

Starter at rest...
has around .050 clearance.

Starter engaged...

There was only one bolt that interfered with another.
I torqued the countersunk bolt and marked where the bellhousing
bolt would pass through.Then milled a chunk out of it.

Clutch is on...

Works Good...
