[quote=Joan][quote=Matt]Hi All Thought I would give you a small update. I put some petrol in the crankcase to test the crank seal. As fast as I could poor petrol in it came out :( I have rebuilt the motor with new double seal bearings and a new crank seal. It now passes the above test and is not leaking. [color:#FF0000] A new double seal bearing will not last very long because the two stroke mixed lubricant has no acces to the balls of the bearing and the lubricant of the bearing will be leached out by petrol vapor. [/color] The crank has no positive form of location in the block. [color:#FF0000]It does have, it is very stuck on the crankshaft axle a so called negative fit and when fitted into the crankcase it should have a forging of the crankcase around its perimeter ( engine type 3800), actually a once in a lifetime construction not intended to be repaired [/color] How close do you have to get it in position? [color:#FF0000]If it is not in position either the big end will jam into the crankcase cover ( to far to the right and also the flywheel may be obstructed by the ignition coil scraping it of and rendering it un usefull [/color] Will it find its natural position over time? [color:#FF0000]Never, there is no little pigmee in there that does the job for you [/color] I think I have it pretty close and the motor turns freely. [color:#009900] [/color] If it is not in good position it will not turn freely for long. please check it. In New Zealand it is winter now so cold riding and night is tne garage are not very appealing. I will report in once I have taken it for a ride. Hopefully all goes well and I have some more speed and cure the choke and jet problem. Cheers Matt [/quote] [/quote]
