Propshaft packing
« on: August 15, 2005, 05:15:46 am »
I noticed that my propshaft packing nut was completely unscrewed.  After inspecting it and reading posts here I saw that it required a cotter pin to hold it in place.  I can't remember the correct packing but I do remember that it should drip a little.  The problem is when I line up the holes for the cotter pin it is either too loose (constant stream of water and loose nut) or no drip at all and the nut is tight.  I left the nut tight and put in the cotter pin.

Is this bad?

I would start off by repacking the assembly and then just snug up the nut. Never more than hand tight. After repacking mine I let it loose and it does not drip. Remember to put some high pressure lube on the shaft to keep the teflon packing from scoring the shaft and you should be fine.

Follow the links on the left to the 'Propshaft Packing' procedure. It'll talk to how many drips, etc. Big think is that when the driveshaft's not turning, there should be NO DRIPS.

I am with sseiber on this one. If I try to line up the "pre-drilled" holes in the two packing nuts, mine either has a constant small stream of water even when the shaft is not turning or has no drip at all at any speed. I opted to drill a new cotter pin hole at the point where there is no drip when the shaft is not moving but hardly any drip at all when moving. I fiddled for an hour just to get to this point. It was sort of a pain to drill the new hole due to the cramped quarters but it was the only way I even came close. Given the choice, is it better to drip too much or not at all? I worry that I am on the "dry" side.

Also, what's the scoop on the "high pressure lube"? Where do you get it and where do you apply it? It wasn't mentioned in the maintenance procedure link.
Don't be so humble, you're not that great.

Personally, I would always err on the side of no drips at rest. I've put channel locks on mine to get to the farther hole when it was close.

OK guys, thanks for the replies.  This weekend I need to check the drip with the shaft spinning.
