hissing clutch
New user highboy-uprade. I have used some of the suggestions on the forum and all have been very good advice.I need some help with a hissing clutch. Engaged sounds like a vaccum leak put push the pedal to the floor and it quits. No noise from the tob no squeeks and has no slippage problems. Stomping the motor to the floor and still no slips. Never had a clutch to make this sound, but always had gas burners before this. Am I overreacting or is there a problem coming up. Thanks for any imput. Newbie mistake forgot to add that it is a 94 4x4 f-350psd, with 3000000 and 4door long bed

Yes it still has the dual mass in it.I have had some ask me the same thing. I don't think it is gear noise. I allways considered gear rollover as a noise on lugging at low rpm. Thank you for any input you have

It doesn't sound like gear roll-over to me. Thats a typical problem of the single mass flywheels and happens at low rpms.
How many miles on the clutch? It could be a bearing... do you have problems getting it into gear?

Thank you farm69 for response. No problems getting into gear or going through all the gears even reverse. Like i said it is a screwy noise. I have been told the dual mass could be loosing a bearing or two. I am old school 360-390 hiboy and have had other manual trans and nothing like this let me know if you have any idea's. As far as miles I do not know third hand truck

My bad, I miss read your post.
A hissing sound with the clutch depressed is generally a bearing or a tooth dragging on the throwout.
Since yours is making it with the clutch engaged, and not disengaged, i'm going to bet on it being a dragging tooth.
The bearings in the DMF are only applicable when the 2 pieces of the DMF rotate.

One or two teeth on the pressure plate will drag on the throwout bearing. Its not enough to spin it, so it makes a scrapeing sound instead. Its weird. I don't have any idea how they get like that, bit it happens.
The reason I'm not saying bearing is cause it goes away when dissengaged, when the pilot and throwout are in full effect.
Probably just time to get a new clutch.

I think I'm having a very similar problem its a terrible noise that you can hear over the motor only when the clutch is fully engaged and when it's almost fully engaged and the clutch isn't that old. SMF too. and it happened in the last month I don't exactly know when also I have a oil leak in death valley somewhere and i don't know if it could contribute to this the oil leak has been ther awhile.

I have not pulled the clutch out yet. It has not got any worse as far as slipping and the noise problem but it is very noticeable. I am trying to make it last as long as possible before I have to pull it apart. I have talked with a trans and clutch man here in town that has been around a lot of years and he thinks it's a bearing also but there is no way to find out for sure till we take it apart. Best of luck with yours
