The Cub motor reveals it's innards...

When last we left off with the Cub motor we were stymied by this bludgeoned pin that holds the kick lever tight to it's shaft. At some point a previous owner had done this, probably in an attempt to remove the kicker. To get into the motor this needed to come off, sooo....

...with my trusty old stylish mini hacksaw I removed the offending mushroom head...

And after a refreshing brew, introduced the Cub Mag mug, to my Cub motor, for good luck...

Fired up the trusty Mapp gas fueled torch (preliminary beating with a punch and 20 ounch Ball Pein seemed to have little effect...) After a quick heat up and a shot of PB blaster and some hefty blows with the punch/hammer combo, I could see the pin lose it's grip and slip out of the kicker.

The offending pin...

The well used kick lever, with evidence of past welding repairs, I tried to get a pic of the area that the pin was stuck in, with out luck. Wanted to show where it looked like someone had left some drilling scars in there, probably from when they removed another stuck pin by drilling it out. Might pick up another kicker. Or I might just try to use this one again with a fresh pin, not too concerned by looks, since the bike will be an off-roader. We will see. 

After the outer cover is off, there is an inner cover...that come off to reveal...

The innards, of a Triumph Cub motor. I was quite relieved to see it was all there and except for a little rust...looked to be in really good shape. When I had removed the oil feed and return lines the last time I'd worked on it, a little water had come out of the cases. Not much and it was clear, not rusty. As it turns out probably an accumulation from condensation over the years it had sat.

Took this pic, with rod at TDC...to reference timing marks for later reassembly.

This is the point I left off, for this session of wrenchin'. Didn't have a puller at hand for the crank pinion or the correct British socket for the nut on the clutch hub on the other side of the motor. Somewhere in the garage is where I left all my British tools years ago. So far on this tear down I've gotten by with a mix of metric and standard. I had a worn out seven sixteenths wrench that got the head nuts loose. Truthfully most of the fasteners were pretty loose which made this possible with out damaging anything, but for the rest of the job, and reassembly I should get the right tools together...

Summing up, I'm well pleased with the condition of things in there. The crankshaft and rod look good, transmission gears are good . All the bushings looked little worn. The cam and followers in real good shape. One shift fork might get replaced, maybe. Finding .080 rings might be tough, then again something might work out there. The shameless plug for the Cub Mag, is also to remind me to re-up my subscription...which will entitle me to discounts from some of the suppliers that advertise in the mag. Greystones has a good web page, and will probably have most everything that I'll need.

Abandon hope, all ye who enter here....

Funny, I've had pretty good luck with Lucas stuff. We will we see how I get along with this little distributor...Next time, Honda SL 350 project progress...
