good god, this is too much car porn for one thread.
what are the plans for the jag?
haha thanks man!
and I wanted to bag that as well, but Im not getting ahead of myself. One project at a time haha.
my father & I rebuilt the carburetor on her and she rips now. Sounds good with that v8 under the hood.
they came with a straight 6 and a v12, so the v8 fits right in no problem.
It's a pretty common swap for the series I and II XJ's
I didn't get to posting everything we ended up getting done last night.
So at this point I had the standard 4spd transmission, clutch & flywheel and driveshaft out of the white fin tail.
Then it was time to start pulling the Hydrak transmission out of the Brown tail.
We worked around the exhaust on Brown, and got the drive shaft and transmission out...
The actual transmissions are both the same, just the bell housings are different between the two.
Here is a shot of the "automatic flywheel" in the coupler on the Hydrak.
So now that we have everything out from underneath both cars, we realize that the Hydrak has a bigger bell housing, meaning it has a shorter drive shaft than the Standard.
This is yet another reason why having a complete car to pull a swap out of can be key... because I'd now be on the hunt for a drive shaft if I had only bought a transmission haha.
So here you can see the difference between not only the drive shaft lengths, but the sizes in bell housings as well.
Today, the agenda was attempting to pull the pilot bearing on the crank of the White tail that we are using the standard transmission out of.
This would be the only part I would have to order if we couldnt pull it, rendering the swap unfinished until I got it.
With that being said, my father, who is a true master of his trade, did not have the proper outer space Mercedes pilot bearing puller. So he put together a slide hammer puller with parts from all sorts of different tools... and out she came, in perfect condition and rolls smoothly.
While my father was being a magician underneath the White tail, I was up top starting to pull the linkage and steering column (since the Hydrak 4spd column is different than the standard 4spd column).
I color coordinated the linkage arms to make my life 100% easier when it came time to put it all back together.
I disconnected the linkage, and separated the coupler on the steering column shown here.
After some real stubborn, hard to get to bolts finally surrendered, and some motivational twist and turning, the column was free. What a pain.
Since Im also using the steering wheel out of the white tail, I pulled everything as one unit.
Then it was onto pulling the actual brain and lifeline of the Hydrak setup in the Brown tail.
I'll post a shot of one of the diagrams of this complex shifting system.
If you're just tuning in, this is an electric to vacuum operated column shift 4spd automatic/standard with no foot clutch.
The shifter in the column makes an electric connection which sends the signal to a control module, where servos operate a vacuum diaphragm that actuates the auto clutch and gear shifting.
Im sure by this point you can tell why these systems had so many problems.
Here is a shot of the overall workings of it.
Now that you've had a few moments to let that all sink in, here is the electric control module mounted in the car, vacuum lines and all.
And here is the diaphragm actuator.
After pulling everything in the engine bay, here is another look at the control module outside of the car.
And the diaphragm
Here is the entire setup of what makes up the brain and lifeline of the Hydrak transmission, from the column to the actual transmission...
Well that's all for now. I promise all this boring swap business will be done soon, I hope.
And then it's onto the fun stuff... bags.
This thing will be getting low soon so don't fall asleep on me yet!
Good stuff John, hope all is well up north! Great work and killer documentation.
Thanks man!
Things are well up here, you know, in Yankee country.
It may be home, but there aren't any Toots up here, so we both see at least one problem with that.
