Drive Plate? speculation please

The photo makes the misalignment look even worse than it felt when I was groping it! Perhaps I need to get my fingertip recalibrated.

Gosh .... truly a flexible friend ... thank you ... think I need to sort the engine mount issues though ....

 

couple more pics for anyone into flexible coupling porn .... and maybe this will finally shame me into getting the dank hole that is my engine bay cleaned up

 

 

 

Wow, I've just noticed that the engine mount in this picture has lost its top securing nut and doesn't appear to have any thread left. This indicates that the mounting foot has been rubbing up and down that mounting stud for many a day to polish off the threads (if that matches what the photo appears to show). If that is the case and possibly replicated on other mounts then the engine would have been leaping about and wouldn't have helped that coupling life whatsoever. The mounts must be checked to rectify this fault before you think about a new coupling alone!

Indeed ... I retrieved the missing nut from the primeval swamp that lies beneath my engine earlier .... and tomorrow is another day

[HappyBunny]

Well, for those of you following the progress .......

 

a very very nice man, by the name of cereal tiller, called today ....

he furtled in my bowels and jiggled my lump around until my shaft was hard, straight and true, he offered a flexible coupling .... which was willingly accepted. he coaxed a perfect union ....

and then, of course, started clamping down on things ..... thrust bearings tightened .... grubby screws wound down

he pushed my button ... there was no instant spark .... (it is a BMC in winter) .... but slowly the heat rose and everything started to spin in peaceful purposeful perfectly aligned motion ....

and joy of joys, he might see me again to ram something in my stern gland

 

Don't you just love the "finbar saunder's" potential of the back end of a boat .... my puerile sense of humour is so easily, and irrationally, tickled by the scope for double entendres that a boat offers

 

proper test run tomorrow but it would seem that the failure of one rear engine mount had caused excessive movement, and its opposing mount had then worked its top nut off compounding the problem ..... shaft from gearbox no longer where it should be .... strain on coupling too much to handle .... taperlock cracked .... blah blah blah .... whilst i am no expert, i have lived with big diesel engines for years and am a confirmed petro-sexual... but I had not particularly noticed any unusual knocks or clatters .... and if i did, I just turned the reggae up ....

 

What have I learnt? well I shall add a few more things to my weekly checklist ..... and am, yet again, amazed at the generosity of people on this forum in terms of their time and knowledge .... i know loads more about my drive train specifically, and my BMC generally .... all the proper names for things .... met some new friends, appreciated some not-so-new friends and got to know Berko ... great place

 

keeping everything practical crossed for tomorrow ..... and no pilchards were hurt or consumed during the repair of this boat

Well I was inspired by this thread to have as LARGE tin of pilchards for lunch. Delicious! Puzzling thing is they must have been nuclear winter pilchards. Large tin but filled totally by just FOUR pilcahrds. Yerm...

 

I'm surprised you didn't manage to include any mention of entering the weed hatch in your magnificent stream of double entendres!

A happy one, obviously! No doubt because you got to King's Langley... or more likely coz of all the pilchards....

 

Anyway thanks for the advice but all my engines are bolted securely straight onto the bearers, none of these girly rubber mounts for me!

 

Oh dear, was that another double entendre?
