That would be a no.I guess overheating does not do them any favors either.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!

I don't believe they make under-size bearings like that. only .010" and .020". From what I read in the TM, i believe the later crankshafts were slightly bigger diameter by only something like .0005 or something small. I would have to look again, but there was a slight size difference between early and late.I would "mike" the bearing journals before ordering bearings. They could just be slightly undersized and then you would need to go with something like .003" under bearings. That is if they still make that size bearing. If they don't then its off to the grinding shop and .010" undersize bearings.
Medium DutyWell part of my parts are here. New pistons/liners, gaskets and rod bolts!

The bolts were $16 and some change. Not cheap. I cant imagine there being a high demand for these things... even in our hobby. How many people really rebuild a multifuel? Not many it seems.How much were the bolts? Can we get a profile shot?
First off there should be some instructions with the rings, if not then they should at least be marked 1,2 3 etc or compression, and oil wiper. Second the compression rings should have a bevel on them. This bevel will always go to the top of the piston. Third, you always stagger the position of the ring gap between rings. I usually make them 180 degrees apart unless there is more then 3 then I go with 90 degrees apart. This way there is never a straight line down which would allow compression to more easily leak out. On the oil wiper rings if they are a 3 piece design I usually stagger the narrow outer ring gaps. But before you even put the rings on the pistons check them in the new bore. There should be a specific gap needed mentioned in the TM's. You may have to grind the ends of the rings to get the proper gap.
Thanks for the clarification Nancy Pants. You better get your seadoo fixed tonight so you can be on call when I need soldier B to help with this rebuild!Medium Duty
I found this in TM9-2815-210-34-2-2 but that manual only goes up to the LDT465-1C.What I need to find out is how to orientate the piston rings on the piston prior to install. I didn't see that in the TM when I was looking through it. Maybe I need to look again or if somebody wants to chime in, that would be good too. Thank you in advance if somebody does.
Thank you Bob!I found this in TM9-2815-210-34-2-2 but that manual only goes up to the LDT465-1C.
