Pump Cone Grease/oil

[1BadTundra]

I pulled my pump cones today. It had the original grease in it. There was no water inside and the bearings looked good. My question is, I mixed Lucas Marine grease with Lucas gear lube. When I was done mixing it, it had the consistency of real soft peanut butter. I filled the cones about 90% full of it, then used my grease gun to shoot some grease into thew bearings, then reassembled them. Anybody see an issue with putting that much in the cones? The SeaDoo guys said to fill them up. Before I put the drives back on, I wanted to make sure this was ok. Thoughts?

I believe my shop manual says to fill them 50% full. The only issue I can see with packing the cones full would be if the grease expanded it could push out the o-ring on the cone or the bearing seal.

I was thinking that too. But, if it did expand, wouldn't that just help push the grease further forward to the front bearing?

I don't know if it would or not, but pressure will push through the path of least resistance. If that's the O-ring, you might develop a leak.

The least resistance should be through the bearings. At least I'm hoping so
