trchris Posted April 18, 2023 Report Share Posted April 18, 2023 Hi all anyone have ideas as to why my gear lever omits a hissing sound on the 4a ? If l rest my hand on top of the gear lever it alters the noise and becomes quieter. I have a feeling it’s going to be a gearbox overhaul any thoughts? Chris Quote Link to post Share on other sites
Charlie D Posted April 18, 2023 Report Share Posted April 18, 2023 (edited) There is an "anti rattle" (anti hiss?) ballbearing and spring somewhere on the lower part of the gear lever. Could that be not working properly? Charlie Edited April 18, 2023 by Charlie D Quote Link to post Share on other sites
RobH Posted April 18, 2023 Report Share Posted April 18, 2023 (edited) Possibly just a worn anti-rattle spring and/ or plunger, at the base of the gearstick. (Edit - snap!) Items 34 and 35 here Edited April 18, 2023 by RobH Quote Link to post Share on other sites
Lebro Posted April 18, 2023 Report Share Posted April 18, 2023 I think you would get more of a "rattle" than a hiss if that spring / plunger were missing, & only at certain revs. Could just be that the meshing gears are getting a bit worn. Does not indicate imminent failure though. Bob Quote Link to post Share on other sites
SeidelVC69 Posted April 18, 2023 Report Share Posted April 18, 2023 Some grease at the bottom of the gear lever and a new spring (item 39) could help. Dieter Quote Link to post Share on other sites
