[QUOTE="SlowSVT, post: 8368668, member: 20202"] Malcolm Now I understand. Plastiguage should only be used with no oil on the bearing and don't spin the crank. It's a good sanity check but measuring the journals to make sure they are in spec. Bearing are made with extreme accuracy so if you don't have an inside bore guage the plastiguage is a quick and dirty method to confirm the clearance. Don't use any oil when measuring clearances because the oil will give to too tight of readings due to oil film will prevent an accurate reading. That include the end play measurements. all checks should be done "dry" If there is oil on the crank remove it and wipe off the excess off and take the measurement again. If there was oil cought on the thrust faces it's likely you will get that .002-.004" clearance you need. [B]Do not sand any of the bearings![/B] Those things are layered with material like babbit, copper, aluminum, steel. you will screw them up sand them. Yes, you can use "blue" locktite on the main stuts. [U]Don't use "red"[/U] or you will never get them out Gotta run for now. [/QUOTE]
