Open or shielded bearings for a DA 85???
Hello, I have a friend who has dismantled his DA 85 to change the bearings. Both stock bearings are grease packed and has two sided RS (rubber) shields. I wonder if the grease packed bearings are really neccessarry or it it would be ok to remove the inner shield of the front bearing and leave the back bearing completely open? This way the gas/oil mix will wash/lubricate both bearings and it will give less resistance than bearings packed with grease. This is the most common way of istalling bearings in glow engines and I can`t see that it should be any different in this gas engine, I might be wrong though.
The owner told me that there was alot of grease coming out of the front bearing and making a mess around the hub, this is why he is going to change the bearings.
Any comments are appreciated[8D]
