not sure if you refering to the drive belt tensioner assembly part#3, I just get the assembly. they are not individual part sold by honda

 

I was actually referring to the other style of drive belt tensioner, displayed as group #2--the one with a spring rather than a shock. It seems there are any number of places willing to sell pulleys (parts #4 and #6), for example, the site I referenced above. The problem is there are at least two styles of pulley, and how to do you tell the parts guy that you want a particular style (before you actually arrive at his desk and find out that the one he has doesn't match...)?

I've got another one ordered in to a shop to look at this morning. Hopefully it's the right one (bummer that it's $25 more...)

 

Are there two kinds of idler pulleys for the '06? I see there are two kinds of tensioners--one with a spring and one with a shock:

The engine that was recently put into my van has the spring-type tensioner (engine J35A6). Anyway, one of the pulley bearings was dry and squeaking and had to be changed out. I went down to the shop to get one, but it doesn't fit... The dished washer (part no. 5) rides on the shoulder of the pulley rather than settling down inside and riding on the inner bearing race. The original pulley is quite dished compared to the replacement pulley I picked up--its sides are straight up and down (Gates 38006). My original is more like the first pulley here: http://www.autopartswarehouse.com/shop_parts/accessory_belt_idler_pulley/honda/odyssey.html; you can see how it differs from the Gates pulley just below.

So, two questions:
1. can anyone find a part number for #6?
2. could I just put a regular washer in there, instead of the deep dish one?
Thanks for any help.

part number 6 is
PartNo: 31190-RCA-A02

I would not recommend putting a pulley for different application there.
A better choice would be to purchase entire tensioner assembly or replace the pulley with appropriate design.

 

Thanks maxud. I actually got a new assembly with both pulleys for CAD$90 (they guy behind the counter gave me a pretty good discount). We both figured mixing new and old down there wasn't the best scenario. Interestingly, though, both pulleys were of the Gates style, i.e., not dished like the originals...

 

I vaguely remember dealing with a similar issue on Acura MDX tensioner. I ended up replacing the tensioner wholesale, instead of just a single pulley. My reason
was the bearings on a single pulley were Chinese and the entire assembly used something more reputable.
