Torx or Torx Plus for the primary?

Just curious Sgt., what size were the chrome allen heads (including thread pitch) you used to replace the T-27's for the primary? I rounded one of the T-27's off once (using a Torx 27) and don't want to go through that hassle again.

rounded my first one off too. my bit started twisting. took to the dealer and they used an impact torx to get it off and put in a new screw for me. didn't charge me and told me to be careful with them.

I use blue loctite on almost everything with a few exceptions such as the derby cover screws. When using loctite the threads of both the fastener and the threaded part HAVE to be clean (oil free) and dry for loctite to be effective no matter the color. Using fasteners of unlike metal - such as steel screws in an aluminum cover - causes corrosion ( there is a term for this but I'm blanking at the moment) and siezing. Antisieze or blue loctite keeps this from occurring.

GM used to do a lot of things. Like invent the electric starter. I really think that once it is gone, and I think it will be, people will realize that the USA is less secure economically than before. If you look at the company closely, you will see that half of it is salaried people working in engineering, finance marketing etc. The idea that it is just a bunch of overpaid unskilled factory rats is not true. Once it is gone, the Japanese companies will fill the production end with workers assembling cars but the high paying jobs that require college will be in Japan. And that will be one more straw on our camels back.

Actually its MASTER, but whos cares about that! I also use a 3/8" Aircat impact gun and Snap-On sockets to remove them so that bit contact is solid and straight, unlike trying to twist a ratchet on a fastner thats tight. I have had lots of bits break because Snap-Ons are hard, but they shear off clean and pop out of the screw head with a magnet and dont damage the screw.
Allen heads ESPECIALLY chrome ones dont hold ANYWHERE near the torque that a Torx head will.
But hey what do I know I just do this for a living!

My rant on torx , I went to go change the primary oil tonight and the torx in the derby were so tight that the torx bit broke, went and got my other one and it also broke ( the first one was Snap on the second Matco ) I ended up taking off the primary cover to try and heat them from the rear but I was out of gas. I ended up drilling them out and now I have to go to the dealer for a gasket and some allen bolts. Nothing like a simple job taking 2 hours and more money. A dealer did the 1000 mile service so they put them in to tight or didnt change the primary fluid. Just had to vent.

I also had 1 torx bolt on the primary that I broke my snap-on bit in. it started wanting to round. I had barely loosened all the other but couldn't get that one. I took it to dealer and stated the factory put that screw on too loose. they had a mechanic come out with an inpact driver (the kind you hit with hammer) and 1 little tap and the screw loosened. he put a new screw in it and I went home and changed the oil!
