How do you like your scissor-lift? Does it raise and lower precisely? i.e., like a typical hydraulic jack where the user can control the speed as it lowers.

Does the lift provide enough room, height as well as general lift clearance, to drop an engine and transmission?

Thanks,
Steve

Oh, I don't know. I really like it in road racing trim myself.

Unfortunately, the 961 had to be run at a higher-than-optimal ride height, which compromised the looks. I think it had to do with a flat undertray regulation. I will have to review the Norbert Singer book.

Remind me not to get a flat in a 959!

Thanks for the update Wayne, keep em coming.

As far as I know, I'm the only one who owns one and works on it themselves.

:)

Wait until you guys see the next project car!

It's *way* better looking in person. It does not photograph well at all.

Thanks for sharing your project on your 959 with us. About the planetary tool it's both ingenious and complicated! I was wondering how you keep the wheel from turning when you loosen the wheel nut but noticed that the planetary tool takes care of this problem.

Yes, it's specially machined to fit inside the inside edge of the wheel hub there. It's definitely one of the cooler tools I have. I had it sitting on my desk for a long time just because it was cool!

I don't like it, and I don't recommend them. It's really only useful for working on the 959. The other cars won't fit over it, so you have to buy / build custom ramps to make it fit on top. Then, you risk falling off of the ramps, it's a huge pain. Plus the inside of the lift blocks the inside of the car, so you can't easily work on it.

I ordered one of these for the shop, it's not in yet:

It's a portable two-post lift, it's very cool, and I think it will be what I'm looking for here at home. You can easily unbolt it from the floor and stash it away or move it to another bay or another side of your garage.

The 959 had the best of everything in 1987 - including run-flat tires!

Why are there crossover tubes on both top and bottom of that caliper?

Good question. The caliper has some crazy plumbing in the back there, I believe it's related to the very early ABS system on the car. I shot a picture of the backside:

I don't have time to depressurize the hydraulic system tonight, but I will probably be working on it tomorrow and over the weekend. I'll post pics!

Help me here. Why won't a stout hex bar of the correct size attached to something similar to this work if the tool is lost.

I'm thinking a butterfly design would be the better way to go on the above to not bind the nut. Would it work? What an I missing?

Modify this?:

Did he say there were planetary GEARS in the thing?

No, but it's one of those IIRC things; thats why I used the question mark - I'm not sure.:)

(But I'm pretty sure it is planetary gears multiplying the torque - it has to have like 300+ foot pounds? The CGT has the same setup.)

Yeah, he did say reducer earlier. Now I see why the tool is indexed into the wheel.

nevermind. ;)

Look what I found at harbor freight! :)

I could have used one of those after taking my truck in for tires. They must have rattle-jacked the nuts on @ 175 ft. lbs.!

Now. let's see.... we make an indexing five point insert and we are now 959 mechanics! ;)

Thanks Wayne. I always look forward to these updates.

I rode in Porsche's 918 Spyder prototype last week in Germany. It is engineered equally as well. ;)

P.S. - I came across this thread while doing research for my story. SmileWavy

Wow, it's been almost 3 years since I started this. In my defense, I've been pretty darn busy (we moved the entire company to a new location, which is what initially distracted me). I am happy to say that tonight I started working on this again. I'm headed up to Magnus' place in a week or so, so I figured it would be good motivation to get this thing back on the road and running again. I'll post some pictures relatively soon - I got the two front accumulators replaced out (2nd time) again tonight (the experimental ones didn't work out too well on someone else's car). More info on that coming soon.
