Non starting super major
Posted: Mon Apr 10, 2017 12:57 pm
I'd just like to say thanks to the forum. I have the dubious luck of looking after my Grandad's Super Major as I am normally the one that uses it, my Grandad is 91 and can't do everything that he used too.
My Grandad had been using the tractor a while ago and when he stopped it it flat out refused to restart. I managed to look at it over the weekend and it would start with a little sniff of the dreaded easy start, but was sounding as if it had a missfire and was emitting an unusually large amount of white smoke. Having looked through previous threads on here we (my uncle and I) decided to check the timing. We set the timing marks as per the manual and it all looked good, until we noticed that the injector pump coupling on the drive end was loose. We pulled the pump off and found that the drive end coupling woodruff key had snapped at the bottom and had become loose in the shaft. This allowed the coupling to move by almost an inch rotationally. My uncle turned up a new slightly oversize woodruff key which we fitted and then set the timing to where it should be. When we restarted it I couldn't believe how smooth it sounded. I have never ever heard it sound so good.
So with the steering sorted (my uncle replaced the kingpins and bearings last year) we used it in anger for pretty much the whole day on Sunday and it ran pretty much faultlessly including using a flail mower which was probably a bit oversized for the power of the tractor. But it ran it none the less.
So thanks for all your most helpful advice, it has kept a Super Major going and prevented it going to the great big scrap yard in the sky.
