My G3LS 1953 - restoration project
Posted: Fri Nov 03, 2017 9:47 pm
Hello!
Few weeks ago I've decided to byu this motorcycle: http://www.jampot.com/forum/viewtopic.php?f=12&t=22617
And now it is in my garage. This is really unique motorcycle in my country, I going to completly rebuild and restored it and without help it will be difficult.
Motorcycle as you see at photos don't looks so bad, it is quite complete, and have matching frame and engine numbers (1953r). Also dynamo and magneto are proper to year of production.
Main missing parts are: speedometer, left tool box, jampots and oil tank. There are of course a lot of minor missing (nuts, bolts, some of there destroyed by corrosion etc).
The first step in rebuild is to assamble all parts, found and gathered missing, when everything will be complete then I'll start painting, chroming. Engine and gearbox will be the last in rebuild, that it looks there are in good condition, piston are nominal (69mm - whats meant +0.30 on top?), the surface of cylinder's barrel is smooth and polished. The clutch is a bit destroyed by corrosion, all metal plates should be replaced, the chaincase band is ruptured, I hope to find replacements via ebay.
Ok, lets start:)
At the beging first problem, missing bolt which fixed brake anchor to frame, i cant find it, maybe you know it's lenght, diameter, thread and type of head? I will be grateful for photo.
Next - toolbox, according to catalogue there should be two spacers (4mm in thickness), the marks on the toolbox's surface indicates that it was directly screwed to the mudguard, right? So where they should be?
Three threads in crankcase (on the left) are destroyed, someones try to screewed into it bolts with wrong thread, fortunately bolts are really short and only begining of thread are broke, I rescue it by the tap, but please tell mi what type of thread and diameter have oiginal bolts, i cant find it in catalogue.
The last photo shows parts which i cant identyfy, (No 2 is for horn?)
//Added
This information could be usefull:
Frame No. 90260
Engine No. 53G3L 19828
Gearbox No. GB1AJ52
Carburator type: AMAL something like AK1M??
Dynamo L3NL-0
Magneto NI4
