gearchange problem
I'm having an intermittent problem changing gear on my 300GD 5sp manual. It seems fine when driving, although the gearbox is a bit sloppy, however sometimes when i'm at a standstill, say at a junction or roundabout, it just will not go into any gear. It almost feels as if it would be easier to break the gearstick than actually get a gear !!!!!!!! Sometimes pumping the clutch a few times helps, but other times the only thing to do is sit still for 5mins and try again, then i get a gear.However like i say, when driving along it goes into gear fine.
It's recently had a new master cylinder so i'm thinking it maybe has a history of clutch problems. Is it just that the clutch hydraulic system needs bleeding, does it need a new clutch or is it something more serious ( read expensive )?

Don't forget you have a clutch slave on there too, the fact that it helps to pump it says there is a hydraulic problem, change slave and bleed; with new fluid should be good as new. Both of mine just about to be done - no clutch from cold but not too bad when warmed up and seals soften.
Still sounds hydraulic. While my problem is seals hardening (especially noticeable when cold) yours will be worn seals. You will lose pressure as you drive along not using the clutch, thus there is little or no pressure in the system when you come to a situation where you have to use the pedal. If you have changed the master and are still losing pressure, and there are no obvious leaks in the pipes, then it has to be slave IMO. That's certainly your cheapest 'try me' option in any case. Don't forget to change the fluid in the system to make a proper job of it. 8)
Thanks again John :D . It actually got stuck in 1st tonight and had to drive it home like that :evil: Gonna get it sorted this weekend.
If it gets stuck in gear again, then stop the car, put it in second, then start it in gear & drive home like that, just knock it off at every traffic lighht or whatever, will start and pull away in second mate - let us know how you get on... 8)
Changing the master cyl often finds the faults in the slave, I take it you did fit a correct master, there are some alternatives that do not have the correct length stroke, hope fully its only a poor slave or air still in the sytem.
You could take a run down to the G Wagen workshop and have it sorted.
Hi, I had this problem when I first got my 300GD where it gets stuck in either 1st or 2nd especially when trying to change fast. Had to get under and physically move the connecting rods ( 3 off ). When I got home I adjusted the connectors ( took up all play ) and it's been fine ever since. I think there is a set procedure for adjusting them which involves lining up holes in the lever arms and I'm sure someone with a manual will confirm this for you. Worth checking this as it won't cost you a penny and it's very straight forward and not complicated at all. Have fun. :wink:
I tjink you will agree it was worth the trip, not only the wrong master cylinder but the wrong engine.
It will be interesting to see what bell housing gear box combination is fitted when you come down next week, and remember don't go off roading untill we have established the front axle misses the sump.

First of all many thanks to John and Chazz i really appreciate the info :)
Special thanks to Bill Moss though who graciously took the time to look over the G Wagen this afternoon (cheers mate :D ) a great little setup down there and a really sorted G, the difference between his and mine is simply massive although hopefully in the coming months i can do something about that :)
In the end not only is the newly fitted (by the previous owner) master cylinder incorrect, it turns out that it actually has a diferent engine and gearbox :shock: . My suspicion is that the engine is out of a 300d saloon and the gearbox out of a van. But will know more after next weekend.
Then, to top it all on the way home the exhaust blew a hole in itself and it now sounds like a tank ( not necessarily a bad thing i know, but hard to take all the same ). Upon closer inspection by the exhaust bloke it seems that this has been made specifically to fit this new engine config and he reckoned the only way for me to get a new one to fit will be to have it made specially.
anyone know anywhere good?
Sorry to hear about even more misfortune, the guys that sold you this G really tucked you up, dont worry, we can get that all sorted down here for you next week end.
Thanks, The way that guy was tho, i'd be surprised if he even knew it had been changed.
I don't see it as a problem really, she's solid underneath, solid body,the engine seems strong and the difflocks and transfer box work. She was bought as an off road project anyway so i'm not too bothered about originality.
OK your the boss

thanks john, the slave cylinder will be job no 1 then !! :D
Thing is, it's not from cold that i have the problem, it's when i've been driving and come to a stop whilst still in say 4th gear and when stopped try to change into another gear . It still happens even after a long run. Does this make a difference, will the solution still be the same?
