kashmir67 Posted June 17, 2022 Share Posted June 17, 2022 Hello folks, can anyone tell me the spanner size of the sump drain plug on my 1970 13/60 herald please? Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted June 17, 2022 Share Posted June 17, 2022 Is it a hex or square? There's a chance it's not original. For the square plugs on my cars I find a 1/2" square drive a decent fit. Similar to this: Quote Link to comment Share on other sites More sharing options...
kashmir67 Posted June 17, 2022 Author Share Posted June 17, 2022 hello, i haven't been under yet. thanks for the info. any idea on the hex size? Quote Link to comment Share on other sites More sharing options...
cook1e Posted June 17, 2022 Share Posted June 17, 2022 7/16 square, you can get 8 point sockets to fit which are really good if it's really tight, or if it's not too stubborn just use a 7/16 or 11mm open ended spanner. The gearbox filler and diff filler use the same plugs BTW.... https://www.amazon.co.uk/Stanley-Proto-J5214S-8-Inch-16-Inch/dp/B0026HBGHG 2 Quote Link to comment Share on other sites More sharing options...

Rosbif Posted June 17, 2022 Share Posted June 17, 2022 I've got a new spare hex, for engine sump or gearbox, it is a 13/16". The hex currently fitted must be slightly bigger as I use a 22mm ring spanner on it, the spanner is quite short which helps dur to the tight space. Yup, you need to get under and look at what's there. Quote Link to comment Share on other sites More sharing options...

Gt6s Posted August 27, 2022 Share Posted August 27, 2022 The magnetic drain plug for the gearbox fits, worth doing. AND IT IS 3/4 Hex head Quote Link to comment Share on other sites More sharing options...
