Hi.

I'm working on replacing shackles, bushings, spring bolts etc. on my 1941 series 61.

But:

The front spring bolts are stuck in the "box" in the frame. The nuts came off, but not the bolts.

Have somebody found a good way to get them out?

I'm skeptical of heating them because I'm worried the rubber bushings might start a big fire....

In addition, I think the rocker panels might bend if I use them as a base to press out the bolts.

I have new bushings and spring bolts so I'm not worried of damaging the old ones.

Should the axle always be taken off to take the tension of the springs before loosening the spring bolts?

Hope to get some good advice:-)

The bolts have to be driven out. The heads have a cerated edge that bites into the metal when they are being fitted, stops them turning and holds them tight in the box.  Guess there must have been a special hydraulic press for it in the day.

Morten,
What Steve wrote is correct, and in my experience the front bolts are not difficult to drive out after the nut is loosened several turns. Squirt around the head of the bolt with a penetrating oil, maybe wait overnight, then using a hammer and a suitable rod to contact the nut, drive the serrated bolt out of the hole in the bracket.

I forgot to mention that you must be sure the spring is not applying any force against the bolt, which would hold it tight in the hole.
