I’d bought a frame of a ’61 M72, years ago, recently I could swap it for a frame from a ’54 M72, the year I was born.
’54 M72 frame
Already I’d bought a sidecar to go along with it, thought that this side car, without torsion bar, was the first type but it seems there was a version before this one !
Sidecar “old type” M72
The second one is this one, the later type was the one with torsion bar.
“First sidecar frame doesn’t have pipe over the mudguard so the axle is fixed only at one side.
It was probably to weak for russian conditions at war”.
info from Leszek, Oldtimergarage
The plan is to paint it in army colour and keep it as much as possible ” original” 🙂
1. the earliest form of something, from which copies may be made.
2. an eccentric or unusual thing.
Axle is stuck in some way
With this “puller” and 5kg weight, I got it off.
Both threads are damaged, axle and inside thread sidecar frame.
Will be a challenge to repair this !
I welded some studs for an small toolbox and attached it.
Painted the frame with “Russian green matt military paint”, the front fork was in an other color, changed that now.
Spoking and balancing the Wheel
The other final drives I have, have needles, this one is equiped with slide bearings.
Use a piece from a pet bottle when you install the seal else the splines will damage the seal !
Size, outside diam. 32, inside diam. 20, thick 21, 28 needles.
If there’s no hole in the ” bottom” cover, drill a hole, else you will ruin the spring !!
The spring goes off easily when you’re able to tap against it, trying to turn it off will have the above result !
Top axle, a bit damaged M72 front axle.
underneath, an axle for a short leading link fork.
