• Gearbox Oil Change: What size Allen?? HELP by Clankin-Rabbit on 06 Apr, 2008 13:54
• Ok guys..been driving my car for a good 2 weeks and everything is doing really well.
  
  Now I want to change the gearbox oil on ol' Thumper but I don't have the size allen to fit the drain plug.  Does anyone know what size the drain plug is on the 4 Speed trannys?  I dont know if there are different types but if it helps, its off of an 81' 1.6NA.
  
  If you guys can reply quickly I would appreciate it because I'd like to get it done today.  Thanks a whole lot.  :wink:

• IIRC it's a 17mm.
  
  You can use a wheel lug with a 17mm wrench on it.

• X2 on the fill plug
  
  I used the head of a bolt that fit in my junk bolt box...no idea what size I just milled around for some thing that fit that hex plug and turned it out with a pair of Vicegrips on the bolt threads

• The head of one of your wheel bolts will do the trick in a pinch.................

• I used a bolt with a 17mm head as well. I double nutted the bolt so I would have something to put a wrench on..

• I made mine out of a 17mm allen wrench.  Wipped out my trusty bi-metalic hack saw blade and had at it.
  
  Took about ten min of sawing, but it works great.  Just drop it into a 17mm socket and voila, 17mm allen socket.
  
  Dump the old crap and put in Redline MTL.
