Broken Gearbox - Phase 3 Old Gearbox Removal

Broken Gearbox - Phase 3 Old Gearbox Removal

So next phase is removal of the broken old Brazilian Bay Gearbox. If you have been following this blog you will have seen the issue with the old gearbox and heard the clunking grinding of the original gearbox and my plans to remove and replace.

This phase 3 is removal of the old gearbox. Being an IRS gearbox with driveshafts and CV joints this will make life a lot easier than the swing axle style.

So here is where we are at:

Remove CV Joints:

Using a 12 spline socket (8mm) and giving each bolt a good spray and clean out all rust, mud , oil & crud before undoing.

Rotating the wheel round gives better access.

Other Stuff to remove:

Now onto the Gearbox Linkage at the front. Put it in 1st or 3rd gear undo small 8 square bolt after removing the securing wire at the front of gearbox. Then put in 2nd or 4th gear and it should separate.

Clutch cable undo wing nut fully, then pull down on bowman flexible section to remove from tube mount of gearbox.

Reverse Light switch - Just unplug handy connector block.

Gearbox Mounts:

Spray and using a 27mm socket (I had to buy one!) and breaker bar loosen these massive bolts!

The front mount has a 17mm nuts on the mount or gearbox. I removed all 4 .

Then placed a trolley jack a little front of the drain plug & pulled.

Out!

Now drained oil:

Might be some metal particles on the drain PLUG!

Most of my differential and final drive!

What's left behind:

Onto the next Phase 4 - Swap parts over from old to new gearbox........ Stay tuned!
