Hello Ladies and Gentlemen.
Now it’s time for the main bearings, it’s a little tricky because it’s very impotent that the main bearings are in strait line to the soleplate for the crankshaft. Otherwise it will be a major problem.
The first is to milling the edges…
… and the bottoms.
Then mark out for the center line and the bolt holes.
Drilling the bolt holes…
…and checking that all fits good together.
Then marking up the centerline with a center dub.
Milling the bearings top for the nuts to fits better.
Is it beginning to looks good?
Now with a ¼“ ball nose end mille mile the main bearings for the crankshaft…
…and also the soleplate.
The last is to drill and reaming for full size. I first drill 6.5 mm then 6.8 then
reamed for 7.00 mm. Then drilling for 7.5 and 7.8 and finally reamed for 8.0 mm.
And here we go, it begins to looks radar good…
…and all dimensions are perfectly suited.
I feel radar happy so far, but it’s much work to be done before I can see the end….
I’ll be back
