Require a parts blowup of Landis CH Universal Grinder 10x24

[pdentrem]

I Require a parts blowup of Landis CH Universal Grinder 10x24 for the wheel head. We are getting a vibration that transfers to the rolls that we are grinding. I took the top off to see what was in there , but do not wish to go any further without a exploded parts or parts list etc. I did rebuild the spindle and whether it's between centers or in the four chuck there was no improvement therefore I have to look at the wheel side.
There are user manuals for sale but not maintainence ones. Our serial number is 480.

Any help would be of service.
