Diff/Gearbox Problem URGENT!!! - Page 2

BrownDog · 11-09-2012, 10:31 PM

i had a look today, i have the CV's for the box and they fit the hubs, the engine is from a BG originally, i have the clutch and flywheel for it, and a clutch slave cylinder so it should all fit, nah its in the backyard im driving a nice monster truck now

Clean_Cookie · 11-09-2012, 10:37 PM

Yeah the hubs will fit but the lengths are different.

BrownDog · 11-09-2012, 10:40 PM

theyre the same length on the drivers side not sure bout the passenger, but the driver side should fit the only difference is the mount the attatches to the motor is further back

TheMAN · 11-09-2012, 10:54 PM

so it's a F series that got stuffed? not surprised
hard to break a G series diff

BrownDog · 11-09-2012, 10:55 PM

yeah, i thought it was g series cuz thats what i specified when i bought the slave cylinder

TheMAN · 11-09-2012, 11:41 PM

well that maybe a problem too... the F series and G series slave cylinders are very different... perhaps the clutch isn't disengaging properly?

BrownDog · 23-09-2012, 03:20 PM

i dont think its the clutch as its been fine till now, i have a box out and im waitng for a new rear main seal [figured id better change while i have the chance], now the next problem is that the speedo gears are different, the one on the new box is cable and mine is electronic and it dosent fit in the new box, what can i do?

BrownDog · 23-09-2012, 03:41 PM

btw i found out why im finding chunks of metal in the oil and possibly the reason why the diff has gone

that is infact a 5 cent coin!!! how it it got in there is beyond me

HAIGHIE · 23-09-2012, 03:48 PM

BrownDog · 23-09-2012, 03:50 PM

is there an adapter for the speedo wire anywhere

Kevaclone · 25-09-2012, 08:35 PM

Things he needs for this swap

Possibly rear mount, need to wait until the bottom gearbox mounting plate is fitted back up. may just need a couple of holes drilled to match or see if the BG plate fits(probably not though)

left top mount or adapter plate to match the mounting bolt pattern

speedo drive or adapter, original BG box has cable speedo, BA has electronic
the F series box has a longer shaft on the speedo drive
is there an adapter to fit the BG cable drive to convert to electronic sensor or a shorter electronic sensor to fit G series in a BA

At the moment he bodgeyed it up with spacers to make it fit... not sure how well it will seal or even if the speedo gear meshes with the drive gear in the box....... shhhhh don't say nothin.... but I am impressed with his ingenuity and ability to do all this work by himself

The boy rebuilt the CV shafts using G series inners and BA shaft and outers so the lengths are still the same

everything else is a direct bolt up as the gearbox was originally with this box in the daughter's BG, including the larger clutch, pressure plate and matching flywheel

only if it's a BG G series
the newer ones are strong enough for some turbo abuse

my mate was pushing more than 17psi on his MP3 here with a regular G series open diff... was fine the whole time... he broke gears instead of the diff!

he recently upgraded to an M factory diff, then his engine got stuffed... always something, isn't it?

BrownDog · 26-09-2012, 06:21 PM

right. well it does work, the bottom mount plates bolts up perfectly, the speedo works, everything else bolts up and works, still need a top mount for the gearbox, but other wise it fits
