Oil Pressure Switch Leak A65L 1970
« on: 02 May, 2017, 12:08:46 »
Probably something easily rectified but don't want to mess up. Trickle of oil leaking past my oil pressure switch at bottom of switch on my 1970 A65 L pre oil in frame. Can't spot any gasket in place or on parts plan and have tightened up in case vibration causing to loosen in past but don't want to overtighten. Only recently started leaking. Did debate as to whether to put some minimal gasket compound at far distance from oil pressure sensor to avoid blocking switch to wrap itself around thread as a seal. Is it a new switch through wear in thread or whatever as bike otherwise oil tight. Any suggestions welcome and thanks. Hugh

Hi Hugh,
              I am not entirely sure where its leaking from the description. If its leaking via the threads, I would remove the switch, clean the threads, using PTFE thread tape, wrap anti clockwise a few times ensuring the switch bore is not obstructed and replace switch.

Best wishes...

HUGH

Thanks Bess for this. Its where the thread on the oil pressure switch screws into the engine and its seeping past there. I sort it tomorrow. Hugh

Hi Hugh,
              Okay, sounds like the thread tape should suffice.

However I have had instances where thread core/root has a tiny crack due to it being inadvertently knocked, it maybe worth further investigation.

Best wishes...
