ricky tango Posted February 15, 2012 Share Posted February 15, 2012 hi guys i'm really struggling on this one , trying to remove the end plug from my rrc air tank as im upgrading from an electric pump to engine driven, the plug is 3/8 allen key and its stuck fast. ive put a 180' twist on a regular allen key with a club hammer and ive tried heating it and using a breaker bar but that coupled with soft halfords tools didnt go well , im now looking at rattle gunning it when its hot but need to find a 3/8 hex supplier in the area, machine mart / cromwells etc all stock metric but that doesnt fit. any suggestions ?

mickeyw Posted February 15, 2012 Share Posted February 15, 2012 Hmmm, not sure which plug you're trying to remove... I know the drain plug (between the two ribs) has a hex socket, but aren't the others just normal spanner male hexagon? Those are the ones you need to remove surely?

yalan Posted February 15, 2012 Share Posted February 15, 2012 you could try eBay - probably have you one before the weekend for under a tenner. Personally I'd call Snap-on head office, get the number of your local man & see if he has one on the van. Round about £20... Quote Link to comment Share on other sites More sharing options...
ricky tango Posted February 15, 2012 Author Share Posted February 15, 2012 with the tank in place the plug is on the tank end pointing to the front of the vehicle, the plug looks just like the drain plug but runs a 3/8 hex , , ive contacted snap on with no luck and drawing blanks at the minute lol Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted February 15, 2012 Share Posted February 15, 2012 Can you get a 10mm one from a local supplier and give it a light tickle with the grinder? Not ideal I know but may get you out of a hole. 3/8 is 9.5mm Quote Link to comment Share on other sites More sharing options...

Biffo Posted February 15, 2012 Share Posted February 15, 2012 If it's that tight, go for 1/2" driver. Quote Link to comment Share on other sites More sharing options...
integerspin Posted February 16, 2012 Share Posted February 16, 2012 Or get a 3/8 socket and bit of allen key. I have twisted snap on allen keys, the best allen keys I have are Unbrako or cheap jap ones. Quote Link to comment Share on other sites More sharing options...
ricky tango Posted February 16, 2012 Author Share Posted February 16, 2012 Did it as was last suggested making my self a socket and after ages on the rattle gun I drilled it out to 19 mm and re tapped it to 1/2 bsp as the head gave up on the bung without it budging at all thanks guys Quote Link to comment Share on other sites More sharing options...
