Rear Block Plugs 59a

[farmerdick]

There are (2) plugs on the drivers side rear. I was told that they were 1/8npt but the plug is larger. Does anyone know what size it is?

 

[Bored&Stroked]

1/4" NPT would be typical.

1/4 NPT. typically one vertical and one horizontal. The oil pressure sender should go in one and sometimes a bypass oil filter is plumbed into the other. Sometimes there is a third plug further inboard that might denote a military application.

Mart.

Thank you. Just what I needed to know. Have a wonderful day.
