   HD11 E - Serial 8788

After I got my newly purchased dozer  in the air, I found 2 trucks with destroyed bearings. The previous owner had been driving this thing in bad condition for a while as there is quite a bit of wear on each end of the roller. 

My manual, while covering the HD11, has an exploded view of an HD16 roller. The drawing shows that the shaft should be a 3/4 half moon at each end. The shaft on my rollers is round . So it uses the square block to attach the assembly to the dozer, rather than the pictured half moon mounting bracket. 
Just inside from the attachment block is a flange. That flange or retainer has been severely worn by being used with failed bearings. It does not appear to be threaded on, but it's also set in close enough to the wheel, that I can't use a press to push it apart. 

So I can't remove the shaft and get at the destroyed bearings... 

Can anyone provide instruction on how to disassemble this?

Thanks

	I would get some good used rollers. You will need a Serial Number, if it is above 10,000 it has the later style undercarriage. If it is less than 10,000 serial number, HD-9 rollers should also work. There are several posts of HD-11 parts.
