Guest Posted June 23, 2012 Share Posted June 23, 2012 For future ref.... Coke is great for removing carbon deposits. Often used in the military for cleaning rifles / pistols after a hard day. Great for the rings and seats also SW Quote Link to comment Share on other sites More sharing options...

tommcb6016 Posted June 24, 2012 Author Share Posted June 24, 2012 I've managed to get it to 30microns one end and 40 the other so that'll have to do !! Just waiting for gasket paper and punch set to arrive, bearings on order in the morning. And order new ring gear from Parajet in the morning too (£££ ) Reassembly will have to wait as I'm off for a week of free flying in Organya :-) Tom Quote Link to comment Share on other sites More sharing options...
tommcb6016 Posted June 24, 2012 Author Share Posted June 24, 2012 Does any one know what the starter ring is from? Or is it a Parajet part? Might be able to find just te ring cheaper elsewhere :-/ Quote Link to comment Share on other sites More sharing options...
ptwizz Posted June 25, 2012 Share Posted June 25, 2012 The misaligned crank is the second most often seen failure from my days of fixing RD250s (after burnt pistons). A spot of weld will help maintain alignment, but once that is done, the next failure is the end of that cranks life. The big end pin is hardened and welding to it produces a very brittle joint. When this fails, it takes a chunk out of the crank web and deposits a lump of hard steel inside your engine. These are bad things.

tommcb6016 Posted June 25, 2012 Author Share Posted June 25, 2012 I still don't know what cause the misalignment though hopefully it will be okay from now on and not move again! Don't fancy a full on crank failure! Tom Quote Link to comment Share on other sites More sharing options...
