Im trying to replace the bellows on my alpha 1 leg, and need some advice.
I can?t seem to find a torx bit the right size to remove the bell housing!
The size is between T60 and T70 and as I cant find anyone who sells a T65 torx bit im assuming it?s a specialist tool for mercruiser.
Don?t worry im not looking to borrow tools!
But can anyone tell me where is the best place to get such a beastie?
Or am I going about this all wrong!
This is my first boat with an inboard and it?s all new to me.
Thanks in advance.

Or you can go to NAPA and order the Hinge Pin Tool 18-9861 which works on both MC and Cobra.

OK and that would be 1/2 inch American not British standard or Wentworth.
You blokes have some weird wrenches over there.

Red (high strength) locktite is factory, so heat is indicated.

Use a 13mm allenwrench in the new math. On this side of the pond we forget the rest of the world uses the meteric system.

As stated, apply some heat with a propane torch to the bell housing where the hinge pins thread in to it. do a little at a time alternating sides to allow the heat to penetrate the metal. Then just instert the tool and pop them out. use a large wrench to turn them (the bigger the better). Once they start moving they should come right out.

The Mercruiser tool isn't much $, and it fits really tight. No stripped fixture. I put a 1/2" drive breaker to it with a socket and off they come, no heat. When you reinstall use locktite and go 90 ft/lb.
