This week's major project is splitting the tractor, to replace the failed oil seal which is leaking oil from the gearbox into the clutch housing. We've got to the point where the only thing still holding the front half of the tractor to the rear is the steering linkage, and I can't remember how we split that last time!
I've tried three different pullers (this is the smallest of them) on these steering arms, but all slip. I think last time I did it I separated the bottom ends of these arms from the linkage rods, but looking at it now I can't even think what tool I could use to separate them.
@simon_brooke Never seen tapered splines. Heat and impact might help. Load it up with the puller, heat it, then shock it with say a brass drift and hammer. Best release stuff I've ever come across is a home made mixture of diesel and acetone.
@withaveeay@yngmar There's a YouTube video showing someone doing it here with just the sort of bearing puller we've got, so I think after lunch I'm going to go up, spray them with a lot of penetrating oil, leave for an hour and then try again with our biggest puller.
@withaveeay@simon_brooke Sorry, no magic solutions. It clearly is supposed to come off that way.
So just the usual: leggo spray, banging on it, heavymetal music, swearing and threatening it with a blowtorch or welder.
If the puller already slipped a few times, it's perhaps time to sharpen its fangs. They do get knackered from that. Or the dodgy method: A Jubilee clip around the paws.
@yngmar@withaveeay Thanks. I've anointed it liberally with penetrating oil, and hit it with a hammer (while the bearing puller was under tension) to try to shock it loose. I suspect I'll try heat next.
@simon_brooke I'd go for the track rod ends rather than removing the arm itself. Tool is either a fork type thing you hit, or a half cup with big bolt at the top. Old skool mechanics loosen the nut and hit end of the arm smartly to drop the rod end out, though it rarely worked for me.
Last time removing the arm on a landy I had to use spanner extension and heat. Be sure not to stand in the firing line when it releases.
@simon_brooke Well done 👍 Coincidentally I was chatting to a neighbour today who was having trouble dismantling a car wiper mechanism, apparently it has splines on a taper.
And that's another achievement unlocked, but I confess I had to recruit the aid of my friendly local blacksmith to find the solution.
Next challenge: remove the input shaft retainer (that's the small circular plate near the top of the big circular plate). I've removed the five screws that secured it.
The manual just says "withdraw the retainer", and I'm looking at it and thinking "aye, right". There must be a way...
