Catastophic belt failure due to locked idler pulley
The idler pulley for my A/C drive belt locked up today causing the belt to over-heat and snap. I've removed the belt and the idler pulley, but the pulleys on the A/C compressor and the main engine drive shaft have rubber debris fused into them.
Before I repace the idler pulley and the belt, I want to clean this stuff off. Using a screw driver has proven difficult - it's really fused on. Has anyone ever solved this problem before?
The good news is I have until June/July to fix this problem!

PB, or Penetrating Blaster should help. Weren't you able to hear the belt squealing before it got to the point of breaking/melting? I know when we had to deal with a stuck tensioner on a Legend that sound drilled into our heads pretty damn badly.

I noticed a mild "whine" about 3 weeks ago and thought the problem was with the alterntor bearings. I did some research on this forum and found others experienced problems with the idler pulley, but since the "whine" wasn't that loud, I just monitored the noise level. I planned to troubleshoot the problem over Thanksgiving break. Then yesterday the "Whine" turned into a loud "SQUEAL" for a couple of minutes while on the highway. I looked in the miror and saw a cloud of smoke trailing me. When I pulled over I saw the belt had melted and snapped.
Today I removed and disassembled the ilder pulley and found the bearings were black and in pieces. I cleaned off the good parts and will replace the belt, pulley, and collar in June if the car is still running (it has 234K miles). The parts I will replace are:
1) Belt (38920-PSG-004)
2) Pulley, Idle (38942-P1R-000)
3) Collar, Idle Pulley (38944-PSG-000)
Total costs will be about $55. All I need to do is figure out how to clean the debris off of the compressor pulley. I'll give the Penetrating Blaster a try if my engine degreaser doesn't work. Thanks.

I had to change mines about a month ago due to horrible bearing noises coming from that area. It's very easy to do on a 2.5TL. All I did was loosen the center bolt on the pulley, and adjust the lever on tensioner to move the pulley up enough to clear the belt. Then I completely took the center nut off and pull the pulley out.

I discovered a tip, just replace the bearing on the Idle pulley. It is a 6203 rs 17 x 40 x 12 mm bearing that you can buy for under $10 online. You push the bearing out of the pulley with a socket and a vise, back in the same way. With the belt and the bearing, your done for under $20. This is a real common bearing, too. Many different cars use this size on their belt tensioners. I bought a pack of ten, since, between me and my kids, we own five Acuras/Hondas.

Hello, can you tell me a Website where you found these parts? Belt # does not show anything on google, but I can find the belt. I can find the pulley for about $35 at one place only, would like to comparison shop a bit, Also, what is the "Collar"?
1) Belt (38920-PSG-004)
2) Pulley, Idle (38942-P1R-000)

can not find 93 Legend Idler pulley at local parts places.
I have a 93 Legend that has the frozen A/C idler pulley. Went 2 years without A/C but I think I will fix it this year. None of the local places has it. I found 1 place on internet that has it for about $40 based on a poster' part number. I was wondering if this is about the going rate and if anyone has source they recommend on the internet. Also, what is the "Collar" for? I was able to take the pulley off easily enough, not sure what is the "Collar" for?

wow this might be my problem as well. My car sat for over a year 500 miles away. I got it back and shortly after the belt spun and broke in about 30seconds when driving it. Maybe the A/C compressor is ok.... need to find that bearing and try this out ASAP!

Both pulleys you've mentioned should spin freely without any abnormal scratching noises. I have replaced both on mines during my ownership. Can't believe it's been 7 years already!

I've had mine in the family going on 13 years. Bought my '96 in '99 and it's been paid off since '04. It's been nice not to have a car payment for it in over 8 years and let me mom use it for a few years to save her some cash.

I guess it would be good to replace both now. I found another thread of yours, didnt you just get another refurb compressor and just swap the clutch pulley? I need to get it fixed along with all the other things lol.

This car has definitely paid for itself already. I too have a few things that I have to replace and put on including new ball joints, suspensions, and not to mention replacing that starter again.
