reboring technical advice please
Posted: Mon Oct 03, 2011 2:32 pm
hello I have a problem with the re-boring of my 860 GTS;
the machinist has used a torque plate process, and is unsure if he has got it right. Apparently the cylinder is clamped into the borer and tensioned to mimic in service condition.
In this shop the cylinder was clamped to a purpose modified flywheel and done as they do harleys and other similar applications.
The boring and honing was done and the bore measured up correct in the jig under tension.
The jig was released-the cylinder was then remeasured and is significantly distorted in the untensioned state. The machinist is a friend and very experienced and is having anxiety
So has he done it wrong?
Advice would be appreciated-Thanks
