Pulled my idler on my Heng Long metal upgrade tank today. Here you can see what I have to work with:
The screw evidently is a shoulder screw which is intended to provide a shaft for the wheel to ride on. But it is not a close fit and there is substantial play in the wheel which allows the tracks to jump on the idler.
So I assume this wheel will not do with the Hennetec axle?
Here is the Taigen "Jagdpanther" wheel, but it does not look correct in the picture - it has "3" stacked wheels not two:
PANTHER G & JAGDPANTHER METAL DRIVE WHEELS AND IDLER WHEELS SET
Maybe this one is what I need?
PANTHER G/F AUSF G METAL DRIVE & IDLER WHEEL SET
The latter appears to have some kind of bearing.
Also I assume I will be cutting away the plastic boss on the Heng Long hull?
