Bearing installation calls for the hole to be transferred through the block into the bearing and reamed. Not every mechanic has or had the tools and inclination to get a press fit, and even so the years have taken some life out of that system. It would not be a bad idea to ream over size a few thou and fit a custom dowel.
After a marathon 1000 mile round trip on Saturday, I have the second pony home. Now I need to make one good one for the DW10 out of the two.
I was pleased to find that this fleabay purchase did not have any huge defects- it turns over, the throttle shaft moves and there are many parts on it that I needed. I think that this one is from a D6 rather than a DW10, but parts seem to be the same for the most part.
The down side is that one bore seems to have some pretty serious scratches. That will need to be fixed. So- are the "semi finished" pistons in the parts books what others have purchased? I am inclined to just sleeve it back to standard rather than machining pistons.
I'm always curious about why engines "die". It looks like someone broke the aluminum intake manifold, tried to weld it and it didn't hold. My other engine has a good cast iron intake manifold so I'm good on that. I also found one head stud that was broken and that likely caused a coolant leak into that cylinder as that was the one with the excessive wear.
Has anyone rebuilt a D6 or DW10 pony recently? is there anything to really watch for? Grinding valve stems to set lash makes me feel like I'm working on another flathead V8 Ford.... But it works. The engine seems pretty simple.
