Hi: Glad you seem to think the same direction that I do; I'm already considering replacing 'both' side pumps and wheel motors, along with hoses, filters, fluid, etc., since if one goes, the other side can't be far behind and if rebuilding them (pumps and wheel motors), I'd rather do that for the right side before catastrophic failure like we've had with the left side. All that, enters my consideration. All that said, is the Oregon brand an upgrade from the OEM ? If not, I'm aware that there are other pump and wheel motor manufacturers - you surely are also. If I'm going to all this bother, I'd far prefer to improve what I have. *Also, I should mention that my rear wheels on the Cub have been canted in at about 10 degrees for some time now, and the tires are bald on the insides as a result. Also, I mention that we run with the heavy duty, deluxe rear mount 3 bag collection system and it's a prime consideration in keeping this machine going. (weight perhaps a factor for wheels canting inward ? ) Please share your thoughts. I do so appreciate you experience.
