hurbie Posted May 11, 2023 Share Posted May 11, 2023 hello all , my until this afternoon very reliable 1987 110 with a disco 200tdi, lt77 and lt230 has lost all drive ... the car stopped with a noise like your having a bad gearshift , a loud grinding noise from the gearbox/transfer case area , with some trouble i got the car another 500 meter , sometimes with a little drive , the remaining distance coasting . took the PTO plate of the transfer case and looked at the mainshaft and gear , spline's are still there . when i put the car in gear (handbrake on) the mainshaft and gear do not turn .... drained the main gearbox , and no metal , just a little "swarf" , also on the magnetic drainplug . got the filter out and no metal there .... so what may be the cause , catastrofic failure of the main box ?

western Posted May 11, 2023 Share Posted May 11, 2023 Check the hub drive member splines, one of mine strip & made the vehicle non movable under it own power until I selected centre difflock engaged Quote Link to comment Share on other sites More sharing options...

western Posted May 11, 2023 Share Posted May 11, 2023 Sounds like a gearbox strip & inspect then. Quote Link to comment Share on other sites More sharing options...
hurbie Posted May 11, 2023 Author Share Posted May 11, 2023 after a bit off google , it seems the 4th gear is direct , there's no drive in 4th either . so not a layshaft bearing failure . could it be the clutch center broken out .....

bishbosh Posted May 11, 2023 Share Posted May 11, 2023 If nothing in the gearbox is turning then it has to be the clutch or upstream of it surely? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 11, 2023 Share Posted May 11, 2023 Was gonna say, sounds like, especially given you had a bit of drive for a while, that it is the clutch catastrophically failing. Quote Link to comment Share on other sites More sharing options...
hurbie Posted May 11, 2023 Author Share Posted May 11, 2023 i'll make a start tomorrow , and see if i can pull the gearbox back enough to see the clutch . Quote Link to comment Share on other sites More sharing options...
miketomcat Posted May 12, 2023 Share Posted May 12, 2023 I had the exact same experience a few months ago. By the time I took the gearbox out I had 4th gear in every gear but that was only after a lazy recovery driver was determined to drive it onto the flat bed, he had to winch it in the end but not before playing a tune on the gears. Unfortunately mine wasn't the clutch so I ended up changing the gearbox. Mike Quote Link to comment Share on other sites More sharing options...

Can you make the noise start & stop with the clutch? If so, it's probably not the clutch... could be a broken mainshaft, I suppose whatever it is now you're pretty much guaranteed to be taking the gearbox out to fix it one way or another.

hurbie Posted May 12, 2023 Author Share Posted May 12, 2023 no noise with the gearbox in neutral , noise in all gears , stops if you push the clutch in ... no drive in all gears (even 4th) making progress : Quote Link to comment Share on other sites More sharing options...
miketomcat Posted May 12, 2023 Share Posted May 12, 2023 Sounds like your gearbox has failed the same as mine did. I never took mine apart but I think the input shaft had snapped then later jammed in 4th gear some how. Even reverse was 4th on mine.

Peaklander Posted May 12, 2023 Share Posted May 12, 2023 That's a result. Far better than a gearbox failure. However, why has it failed? Can you move the gearbox input shaft? Quote Link to comment Share on other sites More sharing options...
steve b Posted May 12, 2023 Share Posted May 12, 2023 The centre of the driven plate letting go is a pretty normal failure mode for Tdi clutches from my experience, often around 100k miles or within 10 years. Good result though, much simpler and cheaper than gearbox issues. Steve 1 Quote Link to comment Share on other sites More sharing options...

western Posted May 12, 2023 Share Posted May 12, 2023 Good find, I had a Valeo plate rip it's centre out & rivets give up which allowed 3 of the springs to escape, pleased you had good parts to get it fixed Quote Link to comment Share on other sites More sharing options...
hurbie Posted May 12, 2023 Author Share Posted May 12, 2023 (edited) in hindsight , the failure wasn't recent , about a month ago i noticed the same noise as when the clutch failed , a short "grinding" of gears (i thought) , before that the clutch was "hopping" when driving real slow , so probebly the springs were gone some time ago ....

Simon Smith Posted May 13, 2023 Share Posted May 13, 2023 I've had two clutches do that on my 110. Seems to be the most common failure. Quote Link to comment Share on other sites More sharing options...

hurbie Posted May 14, 2023 Author Share Posted May 14, 2023 rotated all the tyres (spare to right rear , right rear to front right etc) and found a almost broken drive member ... had a good spare around , so fitted that , but the driveshaft is'nt in a very good order , so i have to make some time to fix that as well ... 1 Quote Link to comment Share on other sites More sharing options...
