Roller repair
Hi,
I have paused putting a treadmill back together with a hope that might be able to get a bit of quick advice.
I have a Smooth Fitness (maybe they are out of business now) treadmill that I am finally reassembling after sitting inoperable for a couple of years to see if I can get any further use out of it. When initially replacing bearings, I did not lube them even around the perimeter, so not only were they extremely hard to get in, but I damaged them as well so they did not last very long.
And when taking them out a second time, they were so difficult to remove that I totally knocked out most of the steel inserts in the ends of the rollers (with the bearings still in them). I did eventually manage to get them out. A couple of the inserts even got small cracks in them, but hopefully they will be okay.
Anyway, I have cleaned up the parts some and received some new bearings, and I hope I can avoid making any more stupid errors. I can either just plain press/pound the inserts back in, put some adhesive/epoxy on the way back in, or completely oppositely put a small dab of lube on just in case they ever need to come out again.
What is the proper protocol for such a repair? Also, each of these inserts has a random number of small holes drilled in their ends (some sort of balancing mechanism?) and I did not note either their numbers or locations when removing them. Is there anything I should try to pay attention to in this regard upon reassembly?
I am not really expecting to be able to get a whole lot more use out of it, but maybe I will get lucky for a little while longer if I do not goof up too much more. Any even very brief recommendations would be sincerely appreciated. Thank you very much in advance.
