Which side should each flywheel go in this recorder?

[akio123008]

I'm repairing a tape recorder and I just realised the thing has two slightly different flywheels. I'm not sure which one should go on which side (I didn't notice that they were different when taking the recorder apart). 

Here's a screenshot of the service manual:

You can see that the service manual describes two different flywheels as well, the first one being 214 and the second one being 226. My problem is that I don't know which one of my flywheels is the 214 one and which one is the 226 one. The picture isn't detailed enough to tell which one is which, the only clue I have is that one of them has a "3" on them and the other one an "11".

I am hoping some tape recorder god will come in and help me figure it out

 

Also, I know it probably won't make as much of a difference which one's on which side, as these wheels are so similar, but I'm troubleshooting the tape recorder, so it's important to eliminate as many variables as possible.

 

BTW the recorder is a Sony tc-v901.

They appear to have different diameters from the picture you provided, I'd put the smaller one closer to the cam gear and the bigger one in the other space. If that doesn't work, just switch them around.

OH I didn't notice that at all! I can see that the "3" one is bigger, so that must be the 214 one then. Thanks a lot!
