I'm reassembling a CT70HKO. Using a Vesrah gasket set. When I took it apart, I noticed the oil pump bolts were loose. Should they be screws instead of bolts or does it matter? Putting it back together and the oil pump spins free and easy up until I put the final torque on the bolts. The manual I have says 6-9 ft. lb. on the bolts. I used 84 in. lb. to torque them but it binds. If I hand tighten them with a nut driver, it'll spin fairly easy but I can tell there's a little bit of bind. The pump itself is in good shape as far as tolerance with a feeler gauge. There is sufficient end play in the shaft. The gaskets in the kit are paper thin and I think too thin. Has anyone ran across aftermarket gaskets being too thin, causing the pump to bind when it's tightened down?
