--> RotaxEngines-List message posted by: "Roger Lee" Hi Henry, Here are a few substitutes. You are allowed to sub Loctite 518 Red or Loctite 5910 for Loctite 574 orange. These are also used to seal the gearbox on the Rotax 912. You can use Permatex "The Right Stuff" which is basically the same as Loctite 5910. These last two do a much better job and that is why you see people getting away from the others. They are both a heavy black paste that are used for sealing gearboxes and transmissions in high vibration areas. When put side by side you can't tell the difference. Loctite and Permatex are the same company now. Permatex "The Right Stuff" can be found at most automotive stores and comes in a small pressurized can i.e. a small whip cream can. This little bit will go a long ways. Clean both surfaces with a scotch brite pad and wipe with some lacquerer thinner or acetone. Smear a thin film on both surfaces and then put them together. Do not over apply this and goop it on. This is one place less is more. What ever little squishes out is ok in or out so long as it w! as a tiny bit and will go through the system, but not if you slather it on and have huge clumps floating around of any of these sealants it isn't good. I have never had a leak using Loctite 5910 or Permatex The Right Stuff. -------- Roger Lee Tucson, Az.
