peter lena 8,583 #1 Posted September 4, 2018 recently picking up a 312-8 ,in addition to wanting to recover a lot of areas of neglect, the main thing was the loose noise this rig made, like a rock in a garbage can. lower front hood pin, swing hinge, removed that and replaced with 2 5/16 x1x1/2" bolts with 2 fender washers on each bolt and elastic nuts , result ? silence. next rebuilt the pto lever rod assembly, I was going to replace the steering rod shaft bearing with a two bolt flange bearing , so I was there anyway. that pto set up was a rattling mess , made up some Teflon washers and spacers and that is smooth and silent, no noise. added a soft extension spring to the rattling clevis pin on the pto curved arm to bottom of arm mount pin, silence. I just love bringing this thing back . my old c-85 has been upgraded the same way, on to the next service area, pete 7 Share this post Link to post Share on other sites
JAinVA 4,619 #2 Posted September 4, 2018 I too hate all the noise these guys can make.The first 416H is really quiet when running and its brothers like to get your attention when running.Big Ugly 2 has a main drive belt that loves to rattle and slap the guard.When I get some time I'm going silence that.In the mean time all have earmuffs hanging on them.

peter lena 8,583 #6 Posted September 5, 2018 Jain VA, picking up on that belt slap, could possibly be the belt tension arm ,on the lower ,or the upper area near engine drive pulley. its just meant to reduce the belt float coming off the pulley. had that on mine, easy fix. just take off the belt guard and look at everything in motion, that will put you right on it. once I started getting after noises , I just regularly check things out , Pete Share this post Link to post Share on other sites
