    GET while the GET'n is GOOD.... Since the "Y" gearbox is the highest fail item in the machine ahead of the FFC Cable and Dusty Board Sensors and Flex Shafts... NOW is the time to get while the get'n is GOOD.... Tim is making a Quality Replacement Part... Paying $90.00 plus $12.00 shipping is the alternate... And unless you are religious about changing the "Y" Bearings you will someday need to replace the "Y" Shaft.

    Just my honest opinion...

    I finally got around to ordering my bearings. I went with the 685 2RS bearings over the 685 ZZ bearing, since the Z suffix stands for dust shield. ZZ only means one on each side. The 2RS suffix stands for two rubber seals, which have the ability to hold even water out of the bearing. They normally cost a bit more. I purchased a large amount to get the price down a bit. If anyone needs or wants some of these bearings, I can offer them up for 75 cents each plus shipping. Shipping should a low as these are small bearings. I had them spec'ed out in the machine shop at work and they are up to spec 5mm id x 11mm od x 5mm wide

    I was thinking that since the new gear box with the larger bearing seems to also fail, the problem may be the grease. Maybe the grease gets broken down after 250 hours of the high pressure in the bearing. What if you took off the two inner seals and filled the space between the bearings with some really good grease. I wonder if the larger volume of grease would extend the bearing life.

    Dan, you could be on to something here. With the size of these bearings and the abuse they take, I could see the grease breaking down and being an issue. The bearing are from a RC dealer. These are used in many RC cars and other RC type vehicles.
