Shaft Packing- wax rope 94 205 LT1

Hey Guys. Bought some 3/16" wax rope to redo the shaft packing. Came in three pieces that I had to cut down to the circumference of the shaft. I removed the old packing which was much thicker than the new stuff. I put 1 piece in at a time and had the seams 180 degrees apart. I hand tightened it and took it too the lake. I put it in the water and it was pouring in so I tightened more. I had to tighten it as far as it could go and it is dipping about 1 drip per second yet. What did I do wrong? Did the dealer give me the wrong size possibly?

Thanks for any help.

Size matters.... Make sure you got the correct size (unknown) for the driveshaft (two different sizes).

I would also forego the wax ring and put in Gore-Tex fiber packing. Wax is really not a good option of the two.

3/16" dia. packing is usually used with 1-1/8" dia. shafts. 1/4" dia. is usually used with one inch dia. shafts.

Tight is tight now but there is no more room for tightening in the future so cut your losses now and go with the Gore-Tex.

Also glance over this link ==> here <== if you haven't already.

Packing rope size is based on the shaft size - LT1 was available in the 94 205 in either the 1:1 tranmission with a 1" shaft or the 1.5:1 powerslot which has a larger diameter 1-1/8" shaft.

3/16 would be correct in a 1.5:1
1/4 would be correct in the 1:1

Edit ^ I like this guy.

Alright, I replaced the 3/16 with 1/4 inch and I can get it to a drip rate of about 1 per 8 seconds. The shaft and coupling are very warm after running it at skiing speeds. I can put my hands on it but was surprised how warm it was.

How warm is too warm? I believe I have the correct drip rate and I realize that there is still going to be some heat due to friction. Thanks for any advice and for the help so far!

I say it's OK. Warm to the touch is not bad. Your mileage may vary but the packing gland and that setup is, what it is. What is nice is the closed sealing system that goes in place of the packing gland.

My experience is that the more you mess with it the more difficult it becomes to aim in on, looking for perfection. Once the packing gets compressed and formed, it is hard to re-use for re-packing. Loosen and tightening is OK but that is about as good as it gets for a single use of packing.
