65 lift cover revisited

Brendon Warren · Nov 12, 2013

As for the lift cover I've replaced the bushings and O-rings. Tightened everything up a lot, maybe not perfect but good enough for who it's for. Now for the next trick, I've would like to adjust the endplay and put a new boot on the top link. I'm assuming it requires a special "spanner" wrench to remove the retainer nut. I thought I saw a post where someone made one, but I can't find it. Any help is appreciated. Thanks

Brendan, first you need to loosen the small grub screw on the right-hand side. This tightens against a small lead ball to lock the threads.Sometimes you can get away with a blunt punch to loosen the nut sometimes you need heat.....sometimes you need a new nut! The inner bit is real difficult to tighten., in fact the easiest way is to cut through the rod with a hack saw so you can get something to grip to get it loosened, remember there is a roll pin through the end of this rod also. You can either weld the rod again or buy a new rod, they are not expensive.

Hi, further to Samn40's reply the attached photo shows the dimensions of what is for us the MF 163 Control Spring Nut Wrench. Time spent making one will be well rewarded especially if it is likely to be used on more than one tractor.
You can do as Sam suggestes or my normal way is to tack weld the rod head to the cup and use a stilson to unscrew the rod. You will need a lathe to remove the weld after. The thread is very fine so it is vital that you use a penetrating fluid such as WD40 immediately you have movement. There is a very real possibility that the parts will 'pick-up' and you will need to replacve both. When reassembling the rod MUST be adjusted so that the spring is tight to turn BY HAND. Don't forget to fit the rubber boot!
Follow remaining instructions as per the workshop manual.

I posted a picture on 10/14/13, page 7 under "Thank you David P". Definitely make the tool. I tried a punch and it is very hard to do since there is so little room to maneuver. I made the tool out of 1/4" steel with grade 8 bolts as the pins following David P"s dimensions. It worked great after heating the housing that the nut sets in. The fine threaded bolt inside I soaked with 50/50 acetone/ATF and then heated the sleeve in fits in very hot and it finally came loose. Just be patient and not try to force anything and it will eventually come loose.
