As mentioned in previuos posts, I have purchased a motor to rebuild.
The most important thing to me is that I learn something - and at the end of it I have a rebuilt motor that I can use in my 77D.
The word 'Mongrel' is because this motor seems to be a bitsa - everybody and his dog has had a go. I am finding this frustrating and I may have ended up with the wrong motor to learn on.
Firstly, thank you to those members who responded to my Engine Stand" post about a month ago - I took all the advise and built myself a rotating stand and it works brilliantly.
What I know so far :
Engine No. 3G0 - 007987 - refering to Skulls charts - US Model 650G - 79-80.
The little bit I have done so far seems to show it has got lots of bits that dont relate to a G model from 79-80.
It has points - this could happen from the factory - but - only 2 bushes fitted in the cam - no labyrinth seal (bushes), just the 2 plain bushes - one each end - indicating points not factory fitted.
It has normal Generator (no TCI trigger) - the stator screws are well used and the wiring is jammed horribly behind the gear shift protection plate - indicating not factory fit.
It has a C type Cam chain tensioner - 1975 - B model.
It has a B model engine breather fitted.
It has very short arm type clutch worm fitted - indicating early model worm.
At this stage Im a bit worried what else I will find when I open the motor up.
I would like to ask for some help/advise at this stage relating to the mismatched parts I have found so far.
Cam chain tensioner - refer photo - the 2mm thick damper washer is missing - if it was installed the plunger would be flush with the end of the adjuster - I beleive this is what Im looking for - is it okay to use this tensioner (with copper washer fitted) ?
Clutch worm - refer photo - why would somebody fit this early type - it only has 30mm distance from pivot point to cable pull point - the clutch seems to be good (visually) and a late model clutch fitted (6 friction/5 steels with cushion plates, no wear on basket fingers, all washers/ bearing in place). Would you recommend fitting a new worm ?
Can I fit a G model engine breather - are there any internal bits in the breather that I have to consider ?
I could not do this without the this forum. I am trying to help myself by studying hundreds of pages of info from the forum so far and will continue to do so, and I appreciate any help you guys give me.
Regards Ray.
