GT6 gearbox removal struggle

[lincolnsix]

I am working single handed to remove my non-overdrive gearbox,  I have a jack under the sump and one under the gearbox.

 

The bell housing is free but I cannot get enough clearance between the end of the box and the propshaft u/j.

 

Do I keep on raising the engine and box,  I have a nice even gap between the engine and the bell housing.

 

The gearbox mount has been removed and the top of the extension.

 

I don't want to do any damage by wriggling it sideways.

 

Any tips would be very welcome.                Thanks  John

Dont jack the gear box

 

raise the engine with a support under the back of the sump either in onto the cranckcase or a lock under the sump. Raise enough to be above the tunnel and prop or close to it. If the prop gets in the way , try tipping the coupling or remove the prop as lasf resort, once it exits the clutch you can lift the tail over the tunnel

 

when its raised get a length of timber and lever between the chassis rail and the base of the box

pry it rewards, as soon as a small gap appears at the back plate

 

sit on floor and just pull it off quick dont let it hang on the clutch, you may need to rotate to get the clutch hsg under the dash

 

Removing the rubber cotton reels make rearwards travel easier

 

DO NOT lever the enging back plate these bend easy and then you get clutch failures due to misalignments

[Pete Lewis]

When refitting keep, engine high, you must get the clutch hsg parallel to the back plate

 

just looking gives a false view, use two long studs in the back of the block to support the box and help alignment

 

when its starts to re enter you check you are parallel use a bit of timber as a gap gauge to help see the gap is equal all round , it helps

If its all fair and square it wil pop on easy

Cover your floors too, the bell housing will strip paint off as you drag it backwards. Cardboard or old carpet works well. AND - be very very careful of the sharp edges of the propshaft tunnel, they like fingers.

On the Spit, cast iron bell housing and overdrive - Oh my back!

 

On the GT6 - Oh the back of my head!

 

But at least you can remove the gearbox from inside the car. Excellent idea.

Just rebuilt a single rail and j type for an area car

 

that cast iron clutch hsg on the 4 pot is a manic heavy lump of old iron

 

on any Od box its worth tack welding the two mounting bolts into the mount base

there is little room to fit any socket or ground down spanner to fit in and hold thd bolt heads

A wonderous design

then its easy to nip the nuts up from down under
