well I work underground so the trucks arnt that big, but everything is done with overrhead cranes, rattleguns, pnumatic/hydraulic jacks. There inst much lifting involved thankfully, but it is still a coupla days to pull out a tranny.

The touble with the pootrol box, is that the box doesent sit flat. The transfer box sits slightly lower then the main box, and the weight is not evenly spread, so you cant just put the box in the middle of the jack and lift.

still like I said never again

SHEEESH thats a LOT of guys to replace 1 gearbox
my jeep box is a 2 man job
i wonder how hard it woulb to replace a gear box in 1 f them big mining trucks.. u no the ones that were on here witrh the disc brakes... ####! that would be a mission and a half

About lifting boxes, We used 4 guys, plus the spanner man to lift into place my pootrol box. Sure it had the transfer case as well, but we took the doors off, put a 2" bar thru the cab, with a chain thru the gearstick hole.
Then a jack holding the weight,with two guys pushing it into place underneath the car, with another putting in the bolts.
Two guys were lifting the box from the top with the pole thru the doors. Massive job, and never again.

Yeah changing a datto gearbox is simple.

An old 1200 coupe of mine used to make that ding noise. Turned out that it was stretching the rear tailshaft yolk bolts, making it loose.

My reverse was very noisy at one stage 2. When eva i used 2 reverse it was sort of in between a winding noise and a really bad scrapping noise. My reverse always used 2 slip out. What i found when i finally got it replaced was that my reverse was missin several teeth and they where grinding inside the box somewhere or somethin!

Replacing a 1200 gearbox is easy compared to most cars ... for example, I can lift it into place without using a jack. Try that with a Ford or GM rwd vehicle.

I love how you just stated the changing of boxes was "EASY"....when I changed mine over I took it 2 a mechanic friend of mine who said that too..
He then found out how "NOT EASY" it is....cheers.


Famous Last Words....

well if its is a grindy noise, then I dont think that the outlook is flash. You can either replace the box, which is an easy job, or just be gentle with it, and hope that it keeps on hanging on. Probally the best option if you dont drive far from a workshop or home, but if you travel a bit, then replacing it will put your minid at rest.
Me I would just put up with it, as I dont travel far, and I have 3 spares.

Thanks for the reply bro, however the noise aint windy, it sort of a grinding noise.
Its getting me a bit worried.

if it is a whine, then it is porbally the normal noise that you get in reverse. I thnk that it is realted to the factthat reverse doesent have syncros.

Could be the answer, but I am not a box guru, gearbox that is...
