b40rt Posted February 15, 2011 Report Share Posted February 15, 2011 I don't need any convincing on the benefits of coppa slip, however, should it be used on Rotax motors? Will the motor act as a sacrificial anode ? Quote Link to comment Share on other sites More sharing options...
yamty175 Posted February 16, 2011 Report Share Posted February 16, 2011 Don't know about Rotax motors specifically but generally copper based compounds are used as 'anti-seize'. I think it's also good for high heat applications also eg. brake calipers. Grease is for lubrication. Jonny. Quote Link to comment Share on other sites More sharing options...
copemech Posted February 16, 2011 Report Share Posted February 16, 2011 I think so when used in ally. Best to stick with grease in engine bolts, although the ali based anti sieze in a mix probably fine. The problems come in the presence of electrolites(water).

yamty175 Posted February 16, 2011 Report Share Posted February 16, 2011 B40RT, where were you planning on using the copaslip exactly? If you are just lubing bolt threads, use the same Aluminium based anti-seize that you use on your spark- plug. Jonny. Quote Link to comment Share on other sites More sharing options...
t-shock 250 Posted February 16, 2011 Report Share Posted February 16, 2011 I have used coppaslip on rotax engines for 15 years with no problems, works really well on the various engine/case bolts that you don't want to sieze in place.

b40rt Posted February 16, 2011 Author Report Share Posted February 16, 2011 Thanks for the reply's, I have been using it for years, but a friend (chemistry graduate)sowed the seed of doubt. The only place I never lubricate is the plug thread, always seems to be enough oil kicking about to do the job. I've noticed that the steel ignition case saver never rusts, even with no paint, so some sacrificial process is going on. Ross Quote Link to comment Share on other sites More sharing options...

02-apr Posted February 16, 2011 Report Share Posted February 16, 2011 Same as last time - the Hydro at end of the month. Might you be twinshocking there? 1 Quote Link to comment Share on other sites More sharing options...

hekto Posted February 17, 2011 Report Share Posted February 17, 2011 I think so when used in ally. Best to stick with grease in engine bolts, although the ali based anti sieze in a mix probably fine. The problems come in the presence of electrolites(water). Just a comment: The Rotax engine is made by magnesium alloy. Magnesium reacts with water. So it has to be painted and i.e. stainless bolts needs grease not to seese in the threads. I would also use ordinary grease or one of the newer ceramic based anti-seese greases.

This one might get washed more than twice a year. Edited February 17, 2011 by 2/4 1 Quote Link to comment Share on other sites More sharing options...
