John Mellor Posted April 27 Report Posted April 27 Hi all in order to clean/replace operating valve just removed transmission cover on my TR4 to get at the operating valve plug. The 7/16 plug was rounded and I've made it worse. Tried mole grips and ( careful) heat which is the limit of my engineering skill. Any suggestions and why was it so tight in the first place? Quote
trchris Posted April 27 Report Posted April 27 Hi John you can buy sockets that are designed for this problem , or l have in the past managed to get the nearest metric ring spanner ( 7/16 is 11 mm so a used 10mm spanner) tapped on and usually it’s a tight enough fit to undo Chris Quote
RogerH Posted April 27 Report Posted April 27 Hi John, is it possible to weld another nut on top Or possiby file some clean sides on the damaged head. Roger Quote

John Mellor Posted April 27 Author Report Posted April 27 Many thanks folks. Roger I assume the plug is ferrous metal if I have to ask someone to weld. I'll try that as a last resort. Quote
BlueTR3A-5EKT Posted April 27 Report Posted April 27 Have you sourced a replacement or will you fettle what comes out and put it back.? Quote

It’s a trivial replacement — I wouldn’t consider putting a messed-up plug back into service. That’s probably what you’re hinting at Peter, eh? Quote
BlueTR3A-5EKT Posted April 27 Report Posted April 27 I don’t think the issue is the filler plug. could be wrong….. I read in order to clean/replace operating valve just removed transmission cover on my TR4 to get at the operating valve plug. The 7/16 plug was rounded and I've made it worse. Tried mole grips and ( careful) heat which is the limit of my engineering skill. Thats the steel capped hex plug. Item 68 in this pic. Quote
Lebro Posted April 27 Report Posted April 27 Yep, thats what I thought. A 7/16"6 sided socket should do the job, if not file the flats(or remains of) down to fit a smaller 6 sided socket (11mm, or even 10mm) Quote

I got sidetracked in the mentioned of double-square sockets. One of the grippy sockets mentioned by Marco or Roger's suggestion to weld a nut to it are the way to go. Heat and a sharp rap on the nut are never a bad thing when one is being recalcitrant. Quote
Steve-B Posted April 27 Report Posted April 27 About 3 years back I was in Texas and knew I had a knackered nut on something on the car. I popped into a car parts/tool shop and got one of these. You hand tighten it onto the problematic nut, plugs into ½ socket shaft and it solved the problem and now lives in my travelling toolbag. Hopefully you can get one here…? Quote
PriceLes Posted April 27 Report Posted April 27 (edited) The hex is small and not that high with the added bonus of the flange being recessed into the case when installed, not a problem perhaps if some form of anti seize was used sparingly including on the copper washer. The room to work in is quite restricted being close to the main case, if you have a M.I.G welder, tacking a nut onto the plug would be easy enough or cutting a slot in the head (if enough material left) with a Dremel would allow an impact driver with large slot head to be used?

I couldn't find any name on it (having long ago thrown away the US card) but I did just find on eBay this one that appears to be identical to mine Stuart. At £12 its a very handy addition. Quote

Z320 Posted April 28 Report Posted April 28 (edited) Hi Rich, I don't know how they are called at the UK, at Germany they are called "Linksausdreher Nüsse" Try "extractor nut set", aviable for a nice price. They are made for example for a 1/2" drive but better you buy a set which also have a hex head. So you can also use them with the 1/2" drive and on limited space with a spanner. Ciao, Marco Edited April 28 by Z320 Quote
