Thank you for the Replies.
The areas im struggling with are with the blue print. Are the bearing jernals. The 1/4 isn't clear what it relates to.
A 1/4 relates is .250 of anything.
When I used to have original cranks reconditioned. The good rear main jernals measured 1 1/4 plus 2.5 thou. Ie 1.2525
So does the 1/4 refur to 1/4 of a though. Or as ive measured in the past 1/4 of a tenth. 2.5 thou ive measured.
Could anyone with Good cranks confirm this.
Also with the front, the 1/4 doesn't make sence. I've seen other crank blueprints that have no tolerance at all, Ie no 1/4
the front bearings don't need to be pressed fit like the rear. As the dog clamps the bearings.so the jernal can be size or slightly under.
If a 1/4 is what in tenths on the rear, 2.5 thou. On the front as an undersize. This would be baggy. So is the front tolerance a 1/4 thou?
Please help to make some sence of this.
Colin, if you meen the valves I'm supplying. Then yes. All valves are exhaust quality. As I'm trying to supply as high quality as I can. AND DO THE PRICE CHECK TEST. I'm keeping prices below everyone else. I can't coment on other suppliers, you will have to ask the same question.
The quality to price is a part of what I'm trying to do for the future, but I need to restrict the range I supply. So I can keep both quality and price in hand.
Check my new head gaskets and see the difference.
This is the same reason for asking some of these questions, quality in the world has to be lifted.
Thanks Tony.
