tilynb61 Posted July 28, 2018 Share Posted July 28, 2018 The 63 B61 Thermodyne, 20 speed,I just got running has a noise / squeak I can't figure out. Put in this forum because I'm not sure where it's from. Engine running, either stick in or out of gear, moving or not. Get louder when moving, mostly in cab. And the wierd part, gets less when I'm sitting in the seat when not moving. Not from the engine, thinking maybe a cab or trans mount? Clutch in or out, no difference.

hatcity Posted July 28, 2018 Share Posted July 28, 2018 Those are the worst...besides electrical make sure it has been greased properly..especially the throw-out bearing this will remove moving parts noise next, just start shaking EVERY part of the cab Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/53929-drivelone-noise/#findComment-403216 Share on other sites More sharing options...
Hobert62 Posted July 28, 2018 Share Posted July 28, 2018 If it changes when there's weight in or out of the seat I'd check around the floor and cab mounts. The added weight could pus the floor against somewhere.

Freightrain Posted August 2, 2018 Share Posted August 2, 2018 How is the rear cab mount area? Mine was patched up loosely by previous owner. I welded the new pieces in solid. Grab cab(with engine off) and rock it. Quote Larry 1959 B61 Liv'n Large......................

tilynb61 Posted September 4, 2018 Author Share Posted September 4, 2018 (edited) Thanks, sorry for the late reply. It was the rear cab mount, cab was repaired there in the past. Rewelded and replaced mount, much better now. Thanks for the help Edited September 4, 2018 by tilynb61 Spelling Quote Link to comment https://www.bigmacktrucks.com/topic/53929-drivelone-noise/#findComment-405500 Share on other sites More sharing options...
