    Just looking for some education here. I've read lots of posts concerning correct clearances for marine engines. Is the difference in clearances due to cooler engine temps? Or are there other reasons for different clearances. Thanks Gary

    How much clearancd is normal in an ag diesel or industial. Specifically a new hollland 3.2L 3 cyl. 3.75" (using the rule of .001) that around .0037 to .004 is ok. The useless pos crankgrinder ground it .0005 UNDER min spec. The spec allows .0005.... he thought that was pretty good. Fucking...

    I would like to hear what options there are, for increasing bearing clearances. In particularly, clearances on a turned down crank! After going thru a long block that i recently picked up and just checking the main and rod clearances with some plastigauge, looks like the they are a little...

    I have read a few of the threads on measuring bearing clearances. I have read that some prefer using inside mic's with out side mic's, rather than a dial bore gauge. What type and brand of inside mic, would you use, a straight style( for lack of a better word), a telescoping snap gauge, a tri...

    So I finally pulled the cover and checked the clearances. It is anywhere from .003 - .008 depending on where you check it on each blade. What should the clearance be and is this far enough out to make a significant difference? I would really rather just run it for the summer and maybe pull it...

    Posting this for my brother BBC, assembling bottom end after a little mishap. Freshly polished crank. Rod bearings are at .0019. Acceptable limits I've read are .0020-.0025. Should he have the crank polished more? Hes already using the oversized bearings(+.0001). Are Mains ok in the...
