BS Question

[Rabbi]

do both balance shafts come out once you do the BS elimination or is it just the oil pump shaft?

thanks

You should pull both of them. The bearings in the front shaft need to be rotated to stop the oil flow to that shaft. The oil pump shaft is supplied oil from the pump and it's ok to just replace it with the stubby shaft. While you are at it make sure you enlarge the relief valve exit. Or you will be running insane oil pressure and start blow seals from it.

You can do it either way. You can leave in the front one and throw on a stubby shaft, but you're still going to be losing a bit of oil pressure through the front shaft. To remove the front shaft you pretty much need to remove the engine (though I'm sure there are ways to do it just by dropping it down or something). If you pull the front shaft you have to rotate the bearings to block off oil flow and that will up your oil pressure a little bit.

any tips on actually rotating the bearings? i had a hell of a time removing them.

Best way to remove them is to put the balance shaft in backwards and it is a perfect fit to tap them out. Turn them 180* and tap them back in.

Or take a 32mmm impact socket or something of equal size and hit them out, another way is if you have the engine out or really wanting to clean it before it goes back together cut a slot off the top and bottom of the bearings and they will fall out you won;t be able to get the rear one. I would also use the stock balance shaft from the oil pump cut it off and weld the hole in the back shut, the stud that comes with other kits is solid and doesnt have a hole/ gallery for oil to go through thus seizing and burning up the oil pump don't learn the hard way. Just my suggestion.
