LET 185mm pulley

Well I finally got my pulley, too bad my car is broken now
Can someone confirm that there are a total of three pulleys in LET 185mm pulley kit - Crank, medium light pulley, and small heavier pulley. Anyone know what the second and third pulleys supposed to replace? and where they are located?

Here is a diagram, just tell me which number the medium and smaller pulleys are going to replace please.
I think the smallest out of the kit is the waterpump and medium pulley seems like it could be a cover and not a pulley.

That is correct. The LET pulley kit comes with a crank pulley, an ideler pulley, and the water pump pulley.

Hmm strage I just measured my "185"mm pulley and it appears to be a 181mm. Could someone who already has a 185 please chime in, or measure theirs? It would really help me out!

I used a metric 30cm ruller to measure the pulley I just got from Eric and it appears to be 18.1 centimeters in diameter, which is 181mm. I alligned the ruler perfectly across, so that the diameter would be measured flawlessly, did it several times, same measurement - 18.1cm. Buttom line is there is no way to measure this pulley I have to be 185mm.

The middle pully in your picture is your water pump pully. It has the 4 bolt holes.

The smaller one is your idler pully.

It must be just a mix-up. That's definitely a 181mm.

I say call Erick or Jerry and let them know incase the wrong pulley was sent due to them being busy mistakes can happen but let them know first before people start to get the wrong impression.

the idler pulley is the small pulley with "LET Motorsports" engraved on it. It's 'guide pulley' #4 in the picture above.

You can see it pretty clearly in the 5th picture of my thread from awhile ago:

They know don't worry, I talked to Eric, it appears to be that the manufacturer made the wrong size
