Lift Arms

later,dave

As advised, spend the bucks and have a shop with a really big press get these off for you. They need a special bolster set ( can't recall what it's called) to get under the edge of the lift arm and push square. Be advised that the bond between the shaft and the arm can be a lot stronger than the hydraulic cover casting - if you go to walloping on it without adequate support, it's not hard to crack the cover in two.

I've seen a 50,000# press pegged out on one of these and still not shift it. Heat, penetrant, tapping, more heat - there's a lot of bonded surface area that needs to break free before these will acome apart.

I believe that there is a master spline in all the components that will not let you install them incorrectly. You should be able to tell by looking at the end of the rocker shaft with the bolt and washer off.

There is one other procedure that might let you get the shaft out and that is to lay the lift housing on it's side on a stump etc with some one holding it and using a steel shaft of almost the same diameter as the rocker shaft and driving the shaft out of the lift arm and the rocker arm that is inside at the same time.If and when you should get the lift arm off the shaft you should carefully measure the diameter of the end of the shaft and if it is swollen from the hammering it should be partially ground off so the it will go through the rocker arm inside.

I have also used a rose bud heating torch to make it red and then with a sledge hammer knocked it off. There probably is a puller that will pull one but as yet I have not found it.Problem is that a puller big enough to pull it has too big hooks to catch the inside of the arm.Wouldn't it have been nice of them to have used a clamp type assembly so that it could have been loosened???

Good luck. You will need it!
