Any suggestions on sand seal pulley install from those who have done it? Did you use permatex? Thanks for any help. I'm still learning.

I just replaced mine.Machine in style, put it in dry except for a little oil on the seal lip.

I had the bolt on kind and the seal blew out in less than a year. I lubed it up with oil.

I use the basic push in without machining. I have done it dry as well as RTV.

I don't like permatex.

You want to lightly grease or lube the seal as already said.

They will all leak some but much better than no seal at all when offroading.

I generally over filled my oil 1/2 quart or more before I went with dry sump.

OH yeah, I never have had much luck with the crank nut staying tight on an all aluminum pulley. Forget the 40 pound strong arm. You will just deform things and the expansion and contraction will make it loose later anyway. Just use the stock washer and give it a one grunt on tightening. The will all leak a bit by the pulley bolt. ( Don't worry about it).

I've run them thousands of miles without serious problems. Watch your belt alignment too.

Get a feel or measure your endplay on the crank before and after your install. If you end up with it to tight because of the seal you will tear it up.

I also take a file and notch TDC, BDC, 10 degree and 34 degree cause the sand removes the numbers over time on my rail.

Sorry for the extra babbling I need to get my first cup of java.... :D

Thanks for the extra babbling. I can use all the help I can get.

I am running the Bolt-On Sand Seal. So far no leaks. I cleaned every thing really well using brake cleaner. I then used a very light layer of Permatex Hi-Tack on the the case and outer surface of the seal. Then put some STP Oil Treatment on the seal. To hold on the bolt I used some Lock-Tight blue and torqued it down to 40ft lbs. So far 9 months and 2,000 miles and not a drip and nothing has come loose.

I got it in but now it's VERY hard to turn. Think I srewed it up?

Yeah, somethings up. Did you get the seal carrier flush with the case? I use a large socket to tape the seal carrier flush with the engine.

Yank the pulley. Does the engine turn free now? If so, you're probably in a bind. The seal needs to come out and go in correctly.

Got the pulley off and it still seems hard to turn but not as bad. I'm pulling on the flywheel to turn it. When the pulley was on, it was VERY hard to turn it grasping the pulley. It's hard then relatively easy then hard. Is that just the compression? I'm really new to ACVW's so I don't know how hard it should be but it seems very hard. Plus in some magazines it looks like there is what looks like a seal. All I got was a degreed pulley and a flat washer with a notch for the woodriff key. Is that correct?

Sounds like you're just fighting the compression.

It also sounds like you're missing the 'seal' part of the 'sand-seal' pulley, or have a standard degree pulley. The 'Sand-Seal' type uses a seal and carrier that attaches to the case, that the pulley 'rides' in.

A non sand seal pulley has ringed grooves on the snout to 'push' the oil back into the case. Does yours have these spiralling grooves?

p.s.
It's easier to use the generator/alternator to turn the engine over, using the nut on the pulley.

Most bolt on SS pulley kits come with a crankshaft spacer.
That flat washer with the notch is it.
Did you install it? It goes in before the seal carrier.
Otherwise the pulley goes in too deep and will rub the seal carrier.
Could be rubbing the oil pump studs too.
It should never turn over hard becaues of a pulley change.
Something is wrong if it does.

Here is a link to a complete system.
You should have gotten all these pieces in your kit.

Yes I did install the washer with the notch. I don't know what the seal carrier is. All I got was the washer and the pulley. Maybe I'm missing something and the pulley is going in too far.

Thu Jul 06, 2006 11:13 am

Does your pulley have the grooves on the snout?

I've seen the seals sold seperately, but didn't know you could buy a sand-seal pulley without the seal being included.

Thu Jul 06, 2006 12:32 pm

I'm at work so I can't see it. Will look when I get home. But from what you guys are saying, it sounds like the guy sold me a regular degreed pulley without the sand seal. The pulley fits tight into the case. I don't see how a seal carrier could possibly fit. Sorry for the dumb-ass questions but I've never done any of this shit before. I'm learning the hard way. Thanks for your help.

The bolt on seal carrier presses into the case were the normal pully would go. It has a flange on it to hold the seal. The machine in syle does not use the seal carrier. THe cases are machined for the seal to fit in the cases with a press fit. A much better setup.

Thu Jul 06, 2006 7:22 pm

Boy do I feel stupid. Pulled the pulley off and looked at it. Realized that it wasn't one solid piece. The seal was stuck on it. So now I'll try installing the washer/spacer first, then seal, then the pulley. See how it goes. Thanks for the help.

Installed spacer, then greased the seal a little and tapped in seal carrier. Pulley went in by hand instead of using a piece of wood and a hammer like last time. Seems to turn just fine now. Thanks.

Glad to here you figured it out. By chance did you put sealer on the seal carrier were it goes into the case

Sat Jul 08, 2006 6:53 am

No. I used it the first time and had a mess to clean up when I removed it. So this time I just greased the seal itself. The carrier was a real tight fit into the case. Now it turns pretty good using a wrench on the alternator pulley nut.
