I am having issues with belt slipping on the above model-and have just begin investigating the issue. two years ago-i replaced the deck and realize if i replace belt-minimum cost is 100 dollars. with newer models available and based upon the age of the current treadmill-any suggestions re either replacing belt at lesser cost ( everything else working) vs purchasing newer model which would have improved cushion.
2nd part of question-I have tightened treadmill upon recommendations. underside of belt is smooth and there is 2-3 inches b/t belt and deck as recommended. any other ways to determine if belt is issue? I do not see any cracking or fraying of belt, and roller continues to move when belt stops. also-I have not recently lubricated belt-would that help? and what lube is recommended? thanks for thoughts
