Oil gauge feed

MikeG · Mar 5, 2015

I've been looking at oil pressure gauges and am trying to decide if it makes much difference if the feed to the gauge is taken off the left hand side of the head or the right? I have the means of making one that will replace the end plate on the right hand side rather than buying one such as what Old Britts sells. Any thoughts/opinions??
Thanks

Seems the right side is busy enough and depending on your arraignment might require a triple length banjo. It doesn't matter if the gauge is being fed from the right, left or right from the connection on the timing case. It is going to be the same reading. Mine is, as most are, from the left side with no issues.

Some feel they are a necessity and others feel they’re an accessory. I think they look good and I really like the function. I also think that how much pressure you have is not as important is simply having some. That is what the gauge shows more than anything. Too much is also not good.

I could see there being a small difference, but why would that matter?
It seems to me, the reason for putting one on is to monitor 'normal' (for your installation) vs 'abnormal' (Yikes! - shut the beast down) readings.

If you merely want to know that there is some oil pressure Pete do as I have and just have a car type oil pressure switch and a light. Mine's been in place for 39 years!

From the left on my bike as this is at the end of the rocker feed line. Logic is that pressure showing at the end of the line equates to pressure at any/all prior junctions.

My oil pressure line is connected on the front right side. Never tried the left side. Anyway, it works for me and feel assured that I have some indication that oil pressure is established. However, I like the Red Light coming on in a low oil pressure condition as it would get my attention quicker. Sometimes while riding I don't glance at the oil pressure gauge as much as I should. I like having one though. Worth every "red cent" to prevent potential engine damage.

For this particular application, the above statement is probably close enough but the laws of fluid dynamics dictate that if there is flow, then there will be a drop in pressure along the line.

Matt Spencer told me that the top of the early Triumph indicator button fits onto the commando base fitting. I'm still looking for one.

I'd like to hear more about this option. Do you have part numbers? What the switch came off of? Pics of the installation?

It's just a standard car type pressure switch, I don't know what pressure they activate at these days but the ones that were fitted to the older cars eg, Ford, Leylands etc. usually turned on at around 5-8 lbs sq inch. I just made-up a Tee and fitted it where the rocker feed leaves the timing cover.

I might think to see the oil pressure light flicker intermittently at or near idle, depending on it's default set point, would be a fair witness as to its function as it pertains to a Norton.
