Modern Vespa

Got my rebuilt motor back from Scooter Mercato and it was packed really well.
Removed it from packing and put it in the engine stand since I need to change out the brake arm for the T5 cable conversion.
Went a outlet straightening around the shop and in about there was a snap and a bang and when I looked the lower shock mount had snapped in half. A very clean break.
Better on the stand than on the road.
Went to the local welding supply to ask for a repair resource and was given a good one.
The question is what filler rod is best used for making the repair.
Thanks
Rick

That is extremely unfortunate, and better on the stand than on the road

Nooooooo! Bummer....

From that picture it looks like it's been cracked for awhile. Break on motor side is shiny, break on rear is dull metal that has had time to corrode.

nope

nope

Look for Gickspeed on here, he does case repairs often.

You would have to use a dye I think, don't think magnaflux will work on aluminum.

nope

Change of direction. Welder wanted motor disassembled.
Spoke with David at SM will send it backdown and Matt will put parts in another set of P200 cases.
Better solution

Oh that's a kick in da coins. :-/
Sorry Mayor.

Thought... this would be a GREAT time to learn to disassemble a set of cases.

Split 'em and take it down to the bearings. Send all your internals back to Matt (Bagged and labeled proper.) and take your case halves to the welder.

If he does a good repair you have an extra set of cases for the shelf or for sale, AND you will have learned something along the way. (Shoot.. you might even decide to reinstall all the bits and bobs yourself.)

You can do it!
We're all here to help.
Ya know you wanna!
Everybody's doing it!
Just say no Yes!

So does the welder want the case stripped so that he can preheat any impurities out of it?

Over the last nearly 60 years I have built small block Chevy's, MG Midget, Austin Healy Sprite and Triumph SCCA race motors, VW sand rail motors and various 2 and 4 stroke motorcycle motors.
It's not a mater of if I can, I simply don't enjoy that part of the pastime any more.
So I do what I enjoy and send the rest out.
As you get into your mid 70's with the energy one has to do things you pick your battles.
Intruly admire the folks that choose to do all aspects of it.

Regarding the welder when I spoke with him he said he didn't want to be responsible for the whole motor. His shop his rules. I'm ok with that.
Regarding shelf stock, when we downsized homes 9 years ago I no longer have a garage just a 10x15 space in the back corner of the walkout basement.
Don't have space to store spares and usually pass along excess parts to others that can use them.

Totally fair and totally understand.
I just wanted to encourage ya in case you did have the bandwidth.

After Hurricane Harvey flooded all my bikes (except the one on the lift) I sent my flooded p200 engine to Gick to rebuild BC I just didn't have the mental space for it at that time. Glad I did bc it was an easy way to put a working bike back on the road while we put the rest of our lives back together.

Looking forward to seeing that glorious white P back on the road!
