I decided not to try to press-off the flywheel
but just do as much of the sandblasting this week
as I could. I found this green-blue color all over but I assume it was a little darker originally (the sand or beadblasting does tend to change and lighten paint before it's gone)
It looks like the atmospheric intake valve holder
units have to be unscrewed. I hope that is not a problem. I plan on a more "normal" factory looking paint job on this one. A little filler
for the pits & holes but no real sanding. I'm using the darker green Ford 1929-31 engine color. |

The valve holders are threaded !
The color you posted looks more blue to me ??
This is doug Kimballs Dunn single that was posted here.
This is original paint on flywheel that Bill Rupka
posted here.Its sure seems that some sort of blue was Dunns original paint color, Does anyone have any more info as to Dunns original paint color?? |

The paint was a dark green before the sand started to remove it. It was like Model A Ford engine green. I could see the waves of green then blue as the paint was coming off. The paint on the cylinders was darker from grease and oil.
The flywheel was the best example. That picture you sent almost looks like you ran over to my mothers basement here in Pa. and unscrewed one housing for me!! |

Picture of the mahagony wood cart I just finished for my 2 cyl Dunn. Is anyone familiar with aligning the cylinder plate with the crankshaft?
Thanks |

I haven't assembled my Dunn II yet, what I intend to do with the plate is to completely assemble the eng then raise or lower the plate to get proper exhaust valve clearance, then with a machinists square, parallel the plate with top of crankcase maintaining valve clearance ??
That sure is a first class cart your Dunn gets to ride on !! |

I never gave the valve clearence a thought!! I was more concerned with the cylinder wall/piston rod being square with the crank. My engine had some damage and the distance of the plate to bed
was not unique all over. From what I measured at disassembly time, the height of the upper face of the nut under the plate measured 3.965", 3.985", 4.005". Some studs were broken and some nuts loose (did not measure them) From these measurements I assumed that I would be ok to start at 4". |

I forgot to mention the cart. It's nice to dress them up a little for the engine shows. I used just oak in the past but I got some big size mahogany a few years ago and the last 2 engines were done in that. It's not a fantastic job if you were to get down and look at it. |

The exhaust valves in my DunnII have been refaced so many times over the yrs that the head diameter is a bit small for the seats, so making a pair of valves is probably the answer and they have very long stems. The stems should be identical in over all assembled length in relation to the cylinder plate. No provision for separate valve adjustment here,deck height will determine both valve clearances.

I'm attaching a picture of my Dunn after getting the crankshaft and the camshaft alligned and the
shims cut etc. I have decided to use the blue loktite (Permatex actually) because there are no lock washers on the bolts and there are just slotted head pan screws holding the camshaft bearings down.
