change it on your driveway `? I have full access to a workshop and a myriad of tools but i have a long weekend this weekend (birthday) so don't really want to be at work - however I'm tempted to get a steering box and change mine out any previous experience??
I did mine on the drive, it's a 1974 but I had a spare box with the puller attached already. I think the arm is the main issue by far, so depends if you have tools at home to do that part?
The box will come out of the bus with the arm attached, so you'll just need some method of holding it steady whilst you wrestle with the puller. Eventually the arm will come away with a bang. A big one! Not sure about heat due to the seals but if you're swapping the box & just need the arm than that shouldn't be an issue. edit, I changed the donut at the same time but be wary, there appears to be 2 qualities of these things one of which is made from crepe paper masquerading as rubber.
I did mine at home,easy to take off the Bus but the puller I brought just kept slipping off so I took it to my Landrover friend who used a good quality puller which stayed on, however the trick was to gently tap where the arm meets the box whilst the puller was under pressure, Job Done real Ales given as a thanks
You won't necessarily get the arm off without heat. I needed a mahoosive hydraulic puller and a blow torch.
I have a NOS rubber as I previously read the same on the forum .. definitely a puller or press then ... hmmm also was going to ask is there only one way the arm refits on ? like a master spline?
There's a procedure in the manuals I think. There must be if I did it successfully haha. The box has to be centred etc. No doubt someone here knows it without looking it up if you don't have Bentley/Haynes Pretty straight forward as the box has an arrow indicator on the case to assist IIRC Never seen a new arm. Only 2nd hand ones attached to knackered boxes that can go for astronomical money! Again, a bod here may have one if you ask
I did it in my drive way with a pulley and a big spanner........which flew off and chipped my tooth. Easy job, just turn your head whilst winding on the puller
I pulled the arm while the box was on the bus. Took a 6 inch puller and an 18 inch breaker bar on the nut on the puller against the weight of the bus. Big big bang but I remembered to just loosen the nut on the arm not take the nut off so all that happened was the puller fell off. Then I took the box off and did the seals on the driveway.
I used a 10ton hydraulic puller under max pressure for a hour and then hit the arm with 2 hammers before it popped off Top tip leave the nut on a bit the box landing on your foot hurts a bit
i used a normal pitman arm puller left it on tight for 5 mins, then tightened it a bit more then give it a tap with a hammer, popped right off
