Opps, know all i ever want or need to on factory Commandos so
only question I have here are always about Ms Peel's deal, nothing
normal Norton applies. Here's the plumbing physic review
in a case that the excrement must indeed flow up hill.
post65677.html?hilit=plumbing%20physics#p65677
Oil in spine tube has more head than oil in a tank and w/o a check
valve near point of frame tank entry, there's nothing to stop back
flow via pump into sump.
I thought Jim had solved issue by the great scavenge pressure pump can
develop, my relief immediately shot down by Mylar reminding
me about low idle pressure flow drop to a trickle.
Yet hm so what?
Oil will still flow to inlet and supply crank by sling under low
loads and eventually scavenge side should have enough wet sump
to shove oil to open a check valve against reasonable spring.
Yet hm am I missing an oiling circulation issue here?
Alas there are at least 5 types and many version of check valves,
flappers, butterfly, balls, diaphragms with and w/o springs, some do and some
don't need gravity to work. I get in weird attitudes for good intervals
so don't want to depend on gravity types.
Not sure if Norton anti-sump valves, designed to barely
resist flow in one direction, would really seal with Peel's
extra height of oil. Beside the a/s valves I've seen advertised
have hose barbs and Jubilee-hose clamps are a taboo item
on Peel.
So Mylar input implies I need a low PSI opener and will return
the hard to open fuel version [$69] and get one i found last pm
for $50 that opens with less than a pound. I call the vendors
to see what they suggest, now I know what to thing about it.
Removed what's seen below including the quart of oil and
battery tray, replaced by what left laid on tank. Not shown
is un-needed stash pipe barrel for pre-filter off inlet valve.
What left when installed, minus the plumbing to get oil to filter
then into frame, all behind the cradle but above swing arm.
Maybe this place has what i need.
