Oil flow indicator ..

Post by Taid »

Just wondering

Return oil to the oil tank is not the easiest thing to see ..

Has anyone been able to put a warning light on the engine lubrication system ..

I don't think the oil pressure is particularly high, but I had wondered if it were possible to put a sensor on the feed to top of the engine (heavyweight singles anyway .. not looked at others)

You wonder too much, Ben :roll:

I take it you mean the copper rocker feed pipe. If so, you could interrupt the pipe with a short piece of transparent tube and relax watching the oil pulses, (plus it would still enable you to worry whether or not the return side was functioning O.K. :) )

Wondering is something I do when I've nothing else to do ... 🙂



There's always a down side 🤔🙄

On a twin you could follow the procedure for installing a pressure gauge and substitute a pressure switch:

http://archives.jampot.dk/book/Workshop ... CHABLE.pdf see page 14

Checking the oil pressure. After engine overhaul, or when
an oil feed shortage has taken place, when the engine is
refilled to the frame, the oil pressure should be checked. An
oil pressure gauge reading from zero to at least 150 lbs. per
square inch is required. It must be mentioned that when a
pressure relief valve is not incorporated in the oiling system
(see table of oiling modifications) the engine must idle for
several minutes until the oil has become warm and the viscosity lowered. Spinning the engine in a cold condition will
generate a pressure of about 300 lbs., which can burst the
gauge. The application of the gauge can be seen in Fig. 3.
The shank of the gauge should be ¼" B.S.P. (.518) x 19 T.P.I.
Use a filter compartment cap of an early type 016179 assembled
with ball and spring to accommodate the gauge, for test
purposes. When an oil pressure relief valve is fitted, the
recorded pressure when cold is between 100 to 110 lbs. per
square inch falling to 25 to 30 lbs. when hot. Without a
relief valve the pressure is about 140 lbs. after warm up and
25 to 30 lbs. hot. In the event of damage to the thread in the
crankcase for the cap 016179 use a tap 11
/8"x20 T.P.I. to clear
the threads. This tap can also be used for the oil distributor
cap orifice.

Makes an interesting read .. something else to ponder ..
