Morris Minor Owners Club

Apologies of this is the dumbest MM question ever but I seem to have a snag with my trunnions (ooh er missus!!).
I've just started fitting a second hand Marina Disc coversion which is modified for Minor hubs and came attached to some front suspension legs. I used the existing top and bottom trunnions as they were nearly new and all seemed to go together well but the bottom trunnion will only thread up as far as the recess for the link pin will allow, with about 5 or 6 threads showing above the trunnion. The lower link on the other side seems to be threaded all the way up. Now the side I have done looks about an inch lower than the untouched side. Both new and old suspension legs look identical but maybe I have missed something really obvious here. Is this normal or am I going nuts?!!. All advice very gratefully received. Cheers.

i take it you took the trunnion bolt out before threrading on

Dennis has it - the pin must be removed - then screw it up - then fit the pin.

I did take the pin out then threaded the trunnion on as far as the recess in the leg then put the pin back through. If I take the pin out and thread it up any further, the pin won't go back in as the threads obstruct it. Are you saying that if I thread the trunnion up as far as it will go then the pin will fit back in? I just can't remember seeing a Minor with any threads showing but then I am pretty inexperienced. Perhaps this is OK. It certainly sounds like I followed the normal procedure when I look at my ancient Haynes manual. Any thoughts?

Yes - the threads are interrupted to allow the pin to go through!

OK thanks. Guess I 'll just get on with the other side then.

Cheers.

Unscrew the trunnion block completely - you should see the threads with the 'interruption' for the pin! Good idea to unscrew/wire brush/slabber on thick grease anyway!

Most grateful for the advice. I'm going to examine the other side before I take it to bits this time. Cheers.

As long as the pin fits back in then the trunnion is screwed in. Make sure that you can turn the trunnion at least 90 degrees either way from straight ahead. The rubber sleeve should cover any exposed thread. And plenty of grease.

Except if the threads are worn - then it can (and does) come apart with the pin still in place !
