This was a "wanted" ad originally - moved it here for future reference:
Urgently need a 6V generator, either NOS/ rebuilt or rebuildable. Or: an armature to rebuild the one which packed up last weekend.
Part numbers (for First Jobs with 6V generator):
Generator Assy: 1105865
Armature, generator: 1887047
Preferably in or close to the Netherlands, as I need to have my C15TA running before 1 May.
Please contact me via email, and/or leave a reply below.
Any tips are welcome! I have sent this request to the usual suppliers/ dealers - this wanted ad is specifically aimed at individuals who may have GMC 270 cu.in. engine spares for C15TA/ Otter/ C60X.
This is what it looks like - note the double pulley.
