Atco HY restoration

I am currently restoring an Atco HY and need to completely strip down the rear roller in order to get to the pawl mechanism. I am stuck and have not been able to remove the spherical bornze bearing at one end of the main shaft. It looks as though a collar on the end of the shaft should unscrew. I have been unable to move it at all. Any advice? There is a hole on the circuference of the smaller diameter of the bronze bearing. Does this contain a grubscrew?

Any advice you can give me will be very much appreciated.

Many thanks.

Ian Tabernacle.

I've restored an HY but the one part that I did not have to take apart was the rear roller, however this parts list from the Club's Technical Help section may give you a clue.

EDIT

Seems to be a problem with that link, but if you go to the Mower Operating Manual section of Technical Help you should be able to access it .

With regards to link not

With regards to link not working, I checked and it seems to have been caused by the erroneous addition of a blank space at the end.

When our CMS saves the page, this blank is transposed into some spurious characters which are added to the link and then make it ineffective.

I have edited the link in the original posting and it should now work.

It's the first time I have come across this particular error in eight years since the we started using this system for the site.

As far as I know, once the bearing bracket (5013 or 5014 on the parts list) is removed the bearing (5191/5192) shells should just slide off. It's possible, I guess, that heavy scoring on the shaft or compacted debris between the bearing and shaft make this very difficult.

The hole you refer to should be for oiling.

Thank you for your relies and

Thank you for your relies and helpful information.

My main concern is the round "nut" on the end of the rear roller shaft adjacent to the drive sprocket. I feel that it should unscrew but I have not managed to move it so far. I wonder if it is a left hand thread. Any information that anyone can provide really will be appreciated.

Problem solved!

Problem solved!

A study of the parts list drawings led me to the conclusion that the bearing was siezed on the shaft.

The application of heat and brute force freed the bearing from the shaft.

Many thanks to those who helped with advice.
