gretle_2.0 37 #1 Posted May 20, 2023 Hey guys I have been getting a rattling sound from the pulley rod area for awhile. At first I thought it was the spring that was worn out so I replaced it but I still get the rattle. I can see the rod I circled in the diagram below rattle when the rpms come up. I am assuming the possibly the bushing #43 is worn out causing this rattle? I just wanted to confirm that was the part I need before ordering more parts that won’t fix the problem. Much appreciated!

Looks like a sintered bronze. Some play is OK, I think you have other problems. Share this post Link to post Share on other sites

Okay thank you, I guess I’ll try replacing the belt and pulley first. Spring was quite worn out so I replaced that but still rattled pretty bad on the pivot arm.

Spring was quite worn out so I replaced that but still rattled pretty bad on the pivot arm. Practically speaking, you really have to get the spring and belt off and then test the idler pulley pivot and the idler pulley itself for play. It doesn’t take a lot of play to cause a rattle if the belt is worn in spots or all over (remember, belts don’t stretch--the V sides wear down and the belt rides lower in the grooves making it seem longer). No need to replace things that aren’t broken! Share this post Link to post Share on other sites
