Just some more Hadley Crank stuff.
I bought a Hadley Crank and rods from Tony a few years ago and I have since got hold of a Sand cast Nippy Crankcase.
I am using the Terry Tuned bearing set up which is non standard !!
The front bearings do not have the same offset between the inner and outer race as the stock bearings so I have bought and fitted shims to correct this issue. I also faced off the inside of the front bearing lip to clean it up due the the Nippy Crankcase I am using is a sand cast case which is thicker than a die cast one and a rougher finish.
I have just fitted the front counterbalance weight which has thown up a couple more clearance issues again possibly due to the sand casting.
The balance weight is just kissing the casting flash below the bearing housing adjacent to the sump filter front bolt hole, it is also hitting the outside of the front camshaft bearing housing.
I will be looking at the other counterweights to check for any other issues.
The crankshaft looks to be centered in relation to the centre camshaft bearing.
I will be doing some comparisons with the Die Cast 9E Crankcase that I have access to.
