Hi Emilio,
did you check the two rubber blocks (engine mounts) which are used to fix the Motor on the Front axel ?
Also the Rubber Block which fits the Transmission to the Body ?The Transmission Shaft really Shakes heavy.
Best Regards Frank
Ciao Emilio,
le vibrazioni si verificano a una certa velocità?
Treten die Vibrationen bei einer bestimmten Geschwindigkeit auf?
Dieses Rütteln kommt häufig wenn die Kardanwelle hin ist.
Albero cardanico difettoso?
Alex
Hello Alex, the vibration seem to be related to engine speed more than the veichle speed: vibration is present even when the vehicle is stationary if you rev the engine: in this case just the engine vibrates, not the whole veichle. on visual inspection the cardan shaft appears in perfect condition.
Hi Jonathan,
I think, it´s speed is too high to make te vehicle "jerk", it would rather rattle, hum or drone.
That sounds to me like the prop shaft...
Regards,
Tiemo
Hi Tiemo, hi forumers! Now the defect seems to appear sometimes even without accelerating… i saved on Dropbox a few videos (bad quality, sorry!) at this link:

actually: fuel filter new, injectors new (not tested before installation though), valve clearance accurately set, both belt's tension ok, injection pump tested and probably ok. I say "probably" because i don't thrust much in the diesel mechanic who tested it. as soon as possible (again covid lockdown now here in italy) i'll make a compression test. ideas? Thanks!
ciao
emilio
