Access to overdrive mounting

[Chris Bracey]

Spitfire 1500. If i remove the gearbox tunnell will that give me access to the rear mounting under the overdriive ?

Correct and I believe there's a cover plate that fits to the floor pan propshaft tunnel that has to be removed to get to the rear flange bolts if needed

the rear mount is accessible with the tunnel off you can see here it sits under the OD tail hsg.

the hardes job is holding the  spanner on the heads of the two bolts thro' the chassis plate , on mine we tack welded the bolts so they cant turn 

as angle of spanner and oil and gunge make them a pain to hold still , the nuts undo from down under 

support the gearbox and take care not to clout he angle drive

 Thank you for the information that is really helpful.

I cut a slot in the nut end of the bolts to take a screwdriver, jam the bolts with a small screwdriver while fitting the washers and nuts, then hold nut with a spanner while rotating the bolt with a screwdriver. Final tightening can then be done with the spanner, always worked well on the overdrive in my Vitesse.

Replace the hex-head bolts with a pair of cap-heads.

Then, an Allen key will stay in the recess, while you get under and turn the nut.  Works for fitting and removing!
