DrGeorgeTompson (Alan) /

Here are some photos and dimensions for the centerstand. This is from a Hero Puch, but i'm pretty sure theyre the same. Idk how helpful this will be but it was a giant pain in the dick to take off. but it's sufficient I think. Let me know if there's anything you want clarification on or any additional measurements you need. right side is mirrored of left side minus the spring tab and rubber stopper thing. all numbers are mm

front side

back side

right side

left side

top side

dimensions from the back side and left side. stand tube is 19.5 not 9.5.

the thin rod across the top is 8mm

mounted on bike

spring length

bolt info

Re: Puch AD

dude you rock!!! this takes all the guess work out of fabbing a center stand. you didnt have to tear your bike apart but you did not only that you detailed the measurements. Thanks for that.

Re: Puch AD

Alex - excellent restoration, lovin’ this thread. Definitely need an AD in my life one day! Also diggin the pPg sign. Keep it up I wanna see this in person soon!

Re: Puch AD

heres some pics of the cast subframe/swing arm. its pretty beefy and intricate so much so that its cast in two parts. mine has a chunk of the chain guard missing from the left half. cleaned up the crusty halves and polished'em a bit so i could put the swing arm back together and start fabbing the center stand.

Re: Puch AD

the center stand is a tomos stand with the top cut off and a pick up truck bumper bracket cut in half and trimmed to make the hinge. i still have to setup a spring for it and finish welding it but the most crucial part is done. thank you Dr george for the pictures and measurements.

Re: Puch AD

Re: Puch AD

took the forks apart. turns out the austro-diamler came with springer forks. i got lucky in that everything was in decent shape and i was able to reuse the grease wiper/seals.

one fork had water inside maybe several tablespoons, it wasn't much but was musty as hell. the same fork leg had a bent tube.

Re: Puch AD

i remember reading a thread and someone mentioned straightening a fork on a press. can't recall who it was but thanks for the tip it worked like a charm.

You rang...

Good work. I elected to use wooden "v" blocks that I made to prevent flat spotting the tubes. It took 3 tries. Ultimately I had to bend backwards past straight slightly to get them straight. Thought for sure I went too far until I rolled it across a bench top.

Re: Puch AD

The Puch AD has a unique fork setup where the steering stem is welded to the frame and the steering tube is cast aluminum fork/headlight housing. its pretty much the opposite of any other bike ive seen.

Re: Puch AD

yup those are the pictures i remember seeing in another thread! thanks motorhead! i didn't even sweat it when i realized the fork was bent thanks to your post.

Re: Puch AD

DrGeorgeTompson (Alan) /

The fork guts in the AD are exactly the same as in the Hero Puch btw

Just be careful when you tighten that left side axle clamp. I cracked mine off. Idk if the cast aluminum is as bad on the AD

Re: Puch AD

Beautiful work

Re: Puch AD

ill keep that in mind Dr.george. thanks for the encouragement Boyd. I appreciate all y'all! (in a southern accent)

Re: Puch AD

That triple tree set up though.

No flex there. Very cool.

Re: Puch AD

yeah someone was really into high pressure die casting, haha

Looks just like the maxi plus I have.

Nice beefy kickstand!

Another thing is u can mix ur mud with equal amount of resin. Same hardener amount as normal. Then ur moped body work is sealed, filled, and hard as steel.(edited)

Re: Puch AD

i've been workin on this doing mostly prep for paint, stripping the wheels and frame. borning stuff. what was interesting was getting the flywheel off.

it came with a rounded nut. after a couple cycles of heating and grinding i was able to break it loose with a steel punch.

apart from the rust on the flywheel and stator, the crank seal seems a bit oily. iam thinking im going to have to change'em. i was hoping to not have to split the cases. anyone have a cheat to change them in place?

Re: Puch AD

Brandon Weiss (Detective brandon to you) /

Those are vertically split cases, so I think you can use a long drywall screw and some vice grips to yank it out. What really helps is to actually tap it in further slightly to get it to move and break its seal. You must be very careful not to go too far in with the screw and damage the bearing.

If it were horizontally split like an e50, it would be near impossible to get it out as they clamp down on the seal much harder.

Re: Puch AD

man brandon you always come through. thanks dude!(edited)
