[email protected] All Messages By This Member #136065 Hello guys,? I'm new here and very much happy to read the useful discussions.? Last year I purchased the AD741 and generally speaking I'm very happy with the performance and accuracy.? Thus, since day 1 there was a loud noise when I turn it on, I asked the technician at the time, and he told me it might be the belt not tighten enough and said I can leave with it. Recently it got worst and for the first time I opened the machine, I saw a lot of black powder probably from the belt.? Is there anyone knows what Is wrong and what I should do about it? Adding some videos,? Thanks! AD741 AD741 - 1.mp4 AD741 - 1.mp4 AD741 - 2.mp4 AD741 - 2.mp4 AD741 - 3.mp4 AD741 - 3.mp4

Brian Lamb All Messages By This Member #136072 开云体育 Looks to me like the belt is too long, too loose and you are at the limits of adjusting the motor further away. I would remove the belt, or read what size it is and get the next smallest one and replace it. The squeaking is from the belt slipping on the drive pulley, also contributes to all the belt dust in the compartment. You can check the alignment, but with that small of pulleys and as much distance is between them, I doubt that is the problem.

The long belt does appear to be a bit loose, but one must be careful with tensioning. ?Too little will result in slippage and belt damage. ?Too much can cause early bearing wear. Good luck, Alex B. toggle quoted message Show quoted text On Apr 29, 2024, at 9:46?PM, hagai@... wrote: Hello guys,? I'm new here and very much happy to read the useful discussions.?

[email protected] All Messages By This Member #136102 Thank you for all the comments guys, I'll try tightening the drive belt and update you on how it went.
[email protected] All Messages By This Member #136118 So today I opened the machine, as you guys suggested, I tightened the drive belt after opening the 4 screws of the engine, it actually helped a lot and there is a significant reduction in the noise.? But I'm at the limit of adjusting the motor, do you think its possible felder supplied the machine with a belt that is too long? also, how would you clean the dust from all the area? thansk
Brian Lamb All Messages By This Member #136119 开云体育 That was my original suggestion, one size shorter on the belt. Vacuum what will come off and then paper towels or rags for the rest.
