Title: 400-4 Oil pressure Switch torque?
Post by: DayvW on August 05, 2014, 05:08:15 PM

Hi all,

Does anyone know the how tight the 400-4 oil pressure switch into the oil pump should be?  I have a slight leak from it (my only leak after the rebuild which is a bit of a relief!).  I gather the thread is tapered - the top part of the thread is pretty corroded, indeed the switch itself looks a bit sorry for itself so as a precaution I'm replacing it - but I cant find any mention of torque settings in manuals (so I want to stop it leaking, but not strip a thread, and I don't want to use any PTFE tape or anything nasty like that to get a good seal).

Thanks.

Mr Honda says 10.8 to 14.5 ft lbs but i do them at 12 ft lbs. I have seen the aluminum crack at 14 ft lbs.
