45" manifolds

#1

Post by David » Mon Jul 02, 2007 5:15 am

Should all 45 manifolds work on a 45 solo and servicar? I have a later servicar motor and manifold number 27020-59 that does not seem like it will work.Thought it came from a servi as well.Seems to wide.any ideas on this might help.

David,

All 45 intake manifolds should work on all 45 flatheads from '32 until '73 as long as the intake spigots on the cylinders are stock and unmolested. The change in the late model servis was to accommodate the new Linkert DC series carbs which have only a 2 bolt mount instead of the old 3-bolt setup.
Try loosening the cylinder base nuts on both cylinders and see if you can wiggle them into alignment with enough space for the new manifold. Install the manifold, snug everything up, check alignment, and then torque it all down.

Thanks will try it tomorrow.The dc linkert is what I have to use and it bolts up to this manifold.Maybe the manifold nuts I have are for another.find out tomorrow.

David,
Always good to here a success story, that's what this forum is all about, a "band of brothers".
Don't forget to leak test the installation when you're done. 45's aren't as touchy about manifold leaks as the OHV's but it is still important and will make a big difference in dialing in the carb.

Found another small problem ,Have two old dc12 carbs.Both are missing throttle lever,have disc and shaft,these spare parts seem to be hard to find.Everybody seems to run the other linkert or mikuni.who has spare parts for this one?
