Hi !!! . Due that I am always driving old bangers , and 60 years old jeeps which are always having trouble with clutch operation... etc.. etc.. I have learnt to drive with an non-operative clutch . It is relatively easy.
By a broken clutch I mean a clutch which can not be desengageed (i.e. a broken pedal , cable , hose , fork ,bearing etc... etc ) ,. but not a totally slipping clutch (which is the opposite issue , a much more worrying breakdown!) .
The biggest issue is to start moving on a flat surface.On most 4x4s , this is easily done by engaing low-ratio and 1st. then just start the engine , with the gear selected . More often than not , the engine will start , and ...voila! , the vehicle 's moving.
Then , it is just about performing the lost mistical art of "double declutching" , which is required for most heavy vehicles. That is , in beetween every gear change , putting the gear in neutral , then revvin' the engine at whichever rpm you guess it will be when the intended gear is engaged, and THEN , engage that gear . If the vehicle has a syncromesh gearbox (most ) , then by appliying a light pressure at the gear stick and variying the rpm , the gear will move itself into gear (as by magic) when the rpm are the right ones .
Try driving at home without pressing the clutch pedal !!.
It is surprisingly easy , and it takes a few minutes to get the feel for it .
The trick is never to allow the vehicle to stop moving , (as then one should stop the engine , and repeat the operation ) .Other tricks is parking the vehicle alwayss downhill , and start the engine , and then -when the vehicle is moving downhill- engage 2nd gear , and so -on .
However it should be noted that 1st gear is NOT syncronized in big 4x4s (most cars ?)_ , therefore making it very difficult to swift into 1st gear doing this trick.
Pls also note that Clutch operation and Engine Starter/battery are complementary (i.e. you can go on driving with either one , but not without both . A broken starter AND a broken cluth , is definitely a serious problem .
have fun !!
