ok, here is where i have been having a little trouble... this being my first ariel, i'm sure that i'm bound to make some mistakes, what am i talking about, i already have. haha
anyway, i had some trouble putting on the timing case. i ordered and replaced the bushes an both the crank case and timing case. i installed the single lobe cam (thanks again dad) and put on the timing case. Both gaskets used. i had a fair amount of side free play with the cam once the case was tightened up.
now my problem was that the mag cam sprocket when slide onto the cam shaft would hit the case before it would stop. Got another sprocket of dad... same problem.
so i pulled it down again and after consulting the old man found that the crank case bush was to far in..... so i drilled it out and ordered another one. 2 weeks later. round 2.
installed the new bush in the crank case (not to far in this time), fitted the cam, and i found it to be slightly tight. i did a dummy mock up, it was still slightly tight when rotating the crank, by slightly tight i mean i could rotate it with one finger, but if i put the conrod at the bottom of the stroke and removed my finger it would stay there and not rise to the top, as before. but the mag cam sprocket went on properly and didn't hit at the back. so after the fear of the 1st set back i decided not to use the large timing case gasket, i used the small round gasket and gasket goo on the entire cover.
now i'm not sure.... is it to tight?? the 1st time it ran with free play but i couldn't get the sprocket to stop on the cam. now its slightly tight but i can get the sprocket fitted properly.
oh yeah i got a little carried away after cleaning the oil pump and decided to install it..... i really hope that the mag chain has a break link.. fingers crossed.
