Quote:Grease the bejeapers out of the walker bearings. Buy an electric grease gun for this. 15 pumps times 10 zerks just takes to long with a hand operated gun. 10 hours or daily, I don't care if the book says 50 hours or not.
Replace all the little plastic blocks on all the belt tensioner adjusters.
It takes nearly 40 pumps to fill one walker bearing after a full day of running.
The electric grease pump is not reliable enough to know how much grease you really put in, especially sinc one can't see well, when the front bearings are full and the grease comes out. I have seen people do a lot of damage with those electric grease pumps either over or under greasing.
From 8+ years around 96xx walker machines I recommend 40 pumps per walker bearing every day with the good old hand pump. And don't get concerned when they seem a bit loose. That's how they are. They get snug being full with grease.
