Do you think they gave you a pulley for a different car? That is crazy all the pulley problems going on around here.

 

did you contact LET, maybe they sent you one for another car? I wouldn't machine it because if you have any future problems they may say it was because you altered it. It has to be a wrong one. I remember they sent someone an E55 water pump pulley by mistake.

 

Wow, right after i posted in the other thread about Waldig being the only one to encounter that issue. Looks like your #2.

Long story short, and read between the lines. I think your most effective remedy is exactly what you said about taking it yourself to the machine shop.

 

I take it you had to shave yours to fit right?

 

Mine fits fine, but Waldig had this problem. I was just saying since he knows the exact measurement to make it right and has access to a machine shop that might be his best route. But im sure LET would send him a new one if he asked.

 

tighed1,
I have the 181 pulley also. I just went out and checked it to verify the belt position. The belt is riding completely on the CP as spec'd. This is a 115.3" Gatorback belt that I put on about 6 weeks ago.
I also pulled the factory belt out of the drawer and checked it. All ribs accounted for and I ran it all summer while making track runs and regular driving.
I noted your comment about the outer ribs being taller than the rest. I got a dial caliper out and could not see or measure any difference across the factory belt or a spare Gates 115.3" belt. I did note that the factory belt is .220" thick and the Gates is .190" thick. But they are both flat all the way across.

MD never said anything about having any problems with his 181, so it might be an isolated few.

 

Have you thought about smashing the Cr%p out of it with a mallet untill it kinda lines up?
Starting to think this is how some companies are doing it.
Give me a call if you need a big enough hammer.

I would question if the pulley is completed seated. I know some folks had to work HARD to get their pulleys on. The first one I got was .003" or .004" too small on the center hole and wouldnt fit on the crankshaft. I got a replacement and it just slipped right on.

Tighed1, did you have trouble installing the pulley or did it slip on?

Also make sure the key is set properly. Not sure if the key was not properly aligned would prevent from going on all the way. Keep us posted. I had to give mine a few more pumps from the high tq impact to sit right.

 

I just took these photos of a new pulley that I have not yet installed on Ashley's SRT and my old pulley. There is the same difference with mine as there is with Tighed's. Should I have the machine shop cut it down? And if the od is small, should I have it cut.

 

Randy, I would do that just yet. The difference may mean nothing. It depends on how far each of the pulleys seat on the shafts. My 181 fits and lines up perfectly. I dont think I am going to pull it to compare to the factory pulley though. If there is enough depth on the crank for the LET to slide on the shaft and line up correctly, you wouldnt need to do anything. If the pulley is tight on the shaft and it binds before it seats all the way, you have a problem with alignment. Just my observations. Contact Jerry for advice.

Thanks for the imput Mike. I was going to have hers put on Tuesday.

 

Woah Dude halt and stop like. This is how I got my crankshaft BENT and were not playing. Took me 5 hours to straighten the 0.090" on the snout. YOu are in a dangerous area. I had the same thing and there is real danger ahead. I wrote and SPOKE to Jerry about this THEN and finally went ahead and cut the pulley shaft down 0.191" to get the belt in alignment.

I could not be more moved than if I were called out for making technical errors.

I will try to locate the photos to show my issue. You know that my pulley flew off partially due to over heating during autocross which causes severe NOSE - DIVES when the engine shut down, and thus my cooling quest(s). Iam now using the steel 178 ASP which is a welded up design now. We need to talk and understand this. Sorry for the issues and that I have what I THOUGHT WAS A UNIQUE problem.

W O DY MY photos from a while ago.

 

Contact LET and keep us informed of the situation as to whether they send you a different one or if you decide to machine it down.

THe 115.3 and the stock belt are the same, Goodyear has them listed as the inner and outer length. I had posted this issue some time ago when everyone was worrying about the belt tension before the pulleys became an issue.

I have been working with Rob at Needswings and designed a fix that he is going to test and release soon, contact him in a couple of weeks for more data. I am running that on mine now for the second week.

Woody Be Happy.

 

Woody, PM sent...

 

It seems we might be in the same boat. I have a 185 pulley and noticed my belt "moving" a couple weeks ago and thought I was losing my mind. Then I looked carefully at all of the pulleys as the car was running(and I had removed the cooling fan for a better view). I noted that the serpentine belt was moving back and forth about 1mm each direction and also found that the belt was 1 rib off.........and hanging off of the back of the crank pulley. Then I came to the conclusion that the crank pulley was sticking out too far(farther than all other pulleys) and assumed it had somehow came loose. I then took my 650ft lbs torque 1/2'' impact and couldn't budge the bolt any tighter. I haven't told anybody about this issue yet as I figured it somehow had something to do with LET sending me the wrong replacement waterpump pulley(got one for an E55 V8 s/c) and didn't want to start throwing accusations. Here's some pics and a little video I made of my findings..........hopefully it's clear enough.

Note how the belt sticks out and hangs over the edge of the tensioner pulley............

Damn... I'm wanting to purchase a 185 pulley in about a month and you guys are scarring me with all the associated problems in all sizes. Squirrel Crusher
