Photos of the 3T so far...

A few photographs showing the current progress - not long before I try and kick it over!

Spot the oil pressure gauge fitted for initial start up!



Plug leads not cut to lenght yet!



 

Timing cover badge refurb

 The current repro badges for the timing cover just do not look right and so I decided to refurb mine. I cleaned the badge carefully (and quickly) with acetone and then sprayed it gloss black - all over. Once fully hardened, I then sanded the face on a flat surface with 800 wet and dry using WD40. Once all the black on the lettering and edge was removed, peek was then used to polish up the brass.


The badge on the right is the original that I have refurbished and the one on the left is the repro one. When polished, I then sprayed a clear gloss lacquer on the badge - as good as new! (it shows a scratch but I could not see it!

Timing disc and oil pressure...

 Just a couple of shots showing the adapter for the timing disc and a take off for the oil pressure in readiness of trying to start the bike:



Above show the timing disc in place


Above is the adapter I made from a spare retaining nut and a bit of steel turned up in the lathe (silver soldered together)


And above is a 'low slung oil pressure gauge' - obviously not a permanent fixture!! Next job is to set the ignition timing and then get all the oils sorted.



Update photos

 Just a couple of photos to show the progress - which is now progressing!


The forks and handlebars now line up!


One step forward, two steps back?!

 Sheesh, I really thought I was making headway until I noticed the handlebars would not sit straight. Careful examination showed the top yoke (H380) was bent.



It is difficult to see but the top one is the bent one and the lower one is a spare I have. How I even managed to put this on quite a while ago without even noticing it, I have no idea. So a strip down of the front forks to replace the tope yoke was done (again):


Whilst about it, I was able to make the drain plugs for the fork oil - 2BA stainless fits very well! One tricky thing to do is to remove the damper retaining bolts at the lower end of the fork tube. Now I know why this spanner has a chamfer on it:


It just about allows you to undo the bolts!

Throttle cable

 You would think the throttle cable installation would be easy - well it is when you know how. I removed the throttle 'stop' and tried (in vain) to install the cable.


It is well nigh impossible to do this when the grip is on the bike, so I removed it and inserted a 3/4" bar into the end (simulating the handlebar). The stop (knob on the top) must be in otherwise the soldered end of the cable will just keep coming away from the unit. Quite difficult to describe but easy to do when you know how. The masking tape is used to keep things out of the way. If you are unaware, the rubber needs pulling back to expose a large circlip. Once this is undone then it all start to make sense as to what to do!

The Amal carb end is fairly straightforward. However it was a good job I checked things over as the throttle slide was damaged and no return spring was in the carb. These faults were soon remedied and the cable inserted. I also did this off the bike.
