To Murphy Switch or Not???

admin

I have a 73 Sa-200, and the question is do I need Murphy switches (oil & temp)or not? I sure would like to here ya'lls input on the subject. I would also like to know the best places to buy the gauges and what kind of cost I'm lookin' at. Any info on the install would help too. I appreciate the help.Thanks Lee
Reply:I would say if it’s running near your work, and gets hot, you’ll smell or see it.If it loses oil pressure chances are it’s a major failure already. But a Murphy may save the crankshaft.
Reply:Price a new Murphy switch setup and then price a short block and a long block. The decision will be easy.                          MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:mla2ofus is right, it sure could save you a lot. No doubt a terrific protection device. Especially for engines that run unattended or remote from operator view and engines at risk of damage from outside forces.I don’t know how much a new Murphy switch system is but if you offered me a choice on a welder, Murphy switch or new bearings and oil pump. I would take the bearings.Your just not prone to catastrophic failure. No  oil cooler to puncture, oilpan not subject to damage etc. Continental distributor function dependant on oil pump rotation. That’s what I meant when I said If it loses oil pressure, chances are it’s a major failure already.
