I also have a MC 106 (M64)
Have had it for 8 or 9 years and it's great for the work here on the ranch. I have been looking for a manual off and during all this time but now I'm starting to have a problem. The right track won't hold tension. I fill it with grease but in about 10 minuets I have to stop and do it again. I'm sure the grease seal is leaking but ... need the procedure for doing the repair. I would love a copy of your manual and happily pay copying fees. Certainly the section on repairing the tensioning cylinders would be most appreciated.
