rafikdous Posted 26May, 2016 Report Share Posted 26May, 2016 Question for a friend of mineCar is a 1976S manualWas driving fine and strong. He took it to a mechanic to drop the engine/gearbox out in preparation for a body restoEngine/gearbox is still one pieceHe wanted to adjust the tappets but can't turn the engine (either way) at all now. Plugs are off and gearbox in neutralAny ideas? Again, this was running fine only 3 or 4 weeks agoThanks Link to comment Share on other sites More sharing options...
ruby82sc Posted 26May, 2016 Report Share Posted 26May, 2016 If you are lucky it could be a seized starter motor that is still engaged in the flywheel, not sure if it can happen with a P t/m but could be holding 2 gears even though the stick is in neutral, otherwise it could be ugly Link to comment Share on other sites More sharing options...
SC 3.2 Posted 26May, 2016 Report Share Posted 26May, 2016 I would check that the selector shaft at the rear of the transmission is not bent, it can be damaged when performing an engine drop and potentially keeping the trans in gear thus may not be letting the engine rotate. Worth a look. Link to comment Share on other sites More sharing options...
MFX Posted 26May, 2016 Report Share Posted 26May, 2016 With the engine out, you could have the box off in 5 mins, and that would at least eliminate that issue. Link to comment Share on other sites More sharing options...
Aircooled Junkie Posted 30May, 2016 Report Share Posted 30May, 2016 I agree the best advice is to take the box off since the engine is out. I had an issue with my 73 E where it jammed in reverse gear, you could start the engine but with clutch depressed, Problem was rectified by removing inspection cover and tweaking selector that had sliped into no mans land.

rafikdous Posted 13June, 2016 Author Report Share Posted 13June, 2016 Turning ugly. Gearbox off, no joy. Timing chain gear checked, no joy. Heads off, no joyLooks like he has to split the case. Very odd. Was running fine before it was dropped Link to comment Share on other sites More sharing options...

Was running fine before it was droppedI trust his mechanic has insurance?Splitting the case sounds drastic, unless the engine was dropped from a height I can't see what could cause a seizure.

rafikdous Posted 13June, 2016 Author Report Share Posted 13June, 2016 not sure mate, should know more over the next few days Link to comment Share on other sites More sharing options...
Coastr Posted 14June, 2016 Report Share Posted 14June, 2016 I assume they have checked all the ancillaries for simple things like bolt in the alternator or jammed distributor or nut jammed behind flywheel?working from first principles it should be something done during removal which generally means a bolt or screw where it shouldn't be or something misaligned.

FAP911 Posted 14June, 2016 Report Share Posted 14June, 2016 Hate to say it but was it driven by someone at the shop I always get a speedo reading when dropping off my car It may not have been but you still need to eliminate all possibilities Really hope its something simple Link to comment Share on other sites More sharing options...

The bill will probably cause a seizure Link to comment Share on other sites More sharing options...
