Good to know about the pushers. Thanks. I was looking at them the other day and wondering why the hell the wear pattern was so far on the outside and not centralized.
If I put spacers between the " cylinder head holding down sleeve nut" and the cam box, I can get it so the valve stem comes in contact with the pusher at approximately the same location as the wear pattern. The cam box still comes in contact with the tallest vertical fin on the right hand side, but it looks as though removing a few thou off the fin with a file would do it...depending on how much things expand and in what direction. Maybe thicker spacers are the answer. They used "sleeve nut distance pieces" on the CS1 and CJ, but don't show them being used on the prewar 30 and 40 in the book that I have. My kingdom for a parts book/diagrams that shows both the garden gate and featherbed long strokes.
I definitely get what you are saying about buggering up a head. It's one of the main reasons I'm trying to dig up info on the subject and would likely hang myself if I fucked it up. If all I end up having to do is shave a small amount off one fin, I'll feel ok going ahead with it. Given that I have to straighten and repair a few other fins and along with the fact that someone removed some fin material to the right of the intake port to clear god knows what… I'll be able to convince myself that it is acceptable and it's probable that I'm not the first to do it.
Burt Munro could have probably done it in his garage with crude hand tools.Anyone out there know if you can mount a long stroke DOHC Manx cam box on a SOHC Manx head? Front vertical fins need to be trimmed for starters….
Yes.. remembered the lash caps, but don't have any at the moment. Should be simple to find (I think) seems to be lots of bits available for SOHC.Longstroke Manx dimensions
Combustion chamber Hemispherical
Inlet valve 1.915 inch dia
Exhaust valve 1.735 inch dia
Valve angle 77 degrees included angle.
Inlet cam M59
Exhaust cam M59
Tappet Dia 0.75 inch Contact radius 1.0 inch
Valve timing IVO 60 IVC 67 EVO 85 EVC 45 (0.004inch clearance)
Con-rod length 7.5 inch
Remember the valves will have lash caps, valve clearance is determined but one of or a combination of lash cap thickness, pusher cap thickness or pusher length.
I'll get to that at some point. I'm in the process of changing from a HP laptop to a MacBook and either I'm digitally challenged or it's easier to upload photos with a MS OS.We like Manx anything in any condition just as long as it's clean -> Pictures please !
I can't address the Windoze vs mac processes since I only use Windoze at work (so don't do much image posting), but I've been using Macs since about 1987 and I've never been forced to use photo bucket or any other hosting site. That said all my photos are either hosted on my own website or attached just like the rare times I attach files from a work computer.I'll get to that at some point. I'm in the process of changing from a HP laptop to a MacBook and either I'm digitally challenged or it's easier to upload photos with a MS OS.
The MacBook is forcing me to use one of those sites like photo bucket and I can't stand all of the ad bullshit.
I guess if you are missing digits your hands will look like spuds!Apparently I am digitally challenged. I went to attach a photo from the Mac, so I could explain the process that was forcing me to use a hosting site… and what came up was completely different than what I had seen before. It was basically identical to what I see in Windows. Who knows what caused the difference….all I ever did was click on the little paperclip. Is there a downside from a security point of view loading them straight from a computer?
