I went on a hunt for a " gudgeon pin" thread for info or add to, but no-go but read some interesting stuff from the archives!!(Richards' 'Rocket 8')
The other week when I set my timing I noticed that the pistons didn't quite make it to the top of barrels...hmm
First thought- I had some big-end holes re-sized at some time but not sure if it was these ones, that'd pull them down hey??
Next I measured each side of each piston to top of barrel- all different.
From left to right-> top of barrel to top of piston->L .0175", 0.0135", R->0.015", 0.025"
Left -4 thou diff. across piston, Right-10 thou diff. across piston
My summation and easy fix is that the little end bushes are reamed out of square, and possibly 'twisted' radially (fore-aft)comprende??
The way I see it this may not pose much of a problem for a while, but could be potentially catastrophic??
As I needed to do a total ~assemble to assess things like brake pedal fit(yeah right), Rocker box on/off, and other stuff ,general mock up, I'll be stripping it anyway to check bushes,C-rod length, and whatever, no big deal but if anyone has other ideas, I'm open to it??
cheers,duTch
PS-
Saw KiwiGf post re- thunderrods?, sent them an email also, may be an even easier fix,+$$,££(option+'3' on macbook), which reminds me,
bsaBill- I found ˚˚degrees˚˚,on the macbook >option+'k'<, Shift'5' is-%, could be different on PC, mine won't kickstart/bootup!!
