hydrolastic displacer removal: which way is anticlockwise?

Post by scooperman »

The Haynes manual states to rotate the front displacer anticlockwise to unlock it from the subframe. Mine will not budge. Before I apply more persuasion I though I should ask if I am trying to move it in the correct direction. I assume anticlockwise means viewed from below, could they have meant viewed from above?

sometimes you have to give the displacer a good whacking with a bit of wood and a hammer to free it up.

Let me guess, you are a technical writer for Haynes?

Anti-clockwise as viewed from the piston end. A filter strap around the body and a few blows from a soft hammer usually frees them.

Endorse that. Changing them in period on International rallies, I invariably found it necessary to do that, even when the displacer had only been fitted into the subframe a few days earlier.

First attempt was using a motorcycle piston ring compressor. This is a band-clamp like an oil filter removal tool, but instead of a lever handle the band is squeezed by a long ratcheting pliers. The band kept sliding off the displacer. I made a substitute band out of thick wire, this grabbed very tightly but would not budge the displacer. A few good whacks with a small hammer were sufficient to break the wire.

I then moved on to an oil filter band wrench, and like the ring compressor it kept slipping on the displacer. A few good whacks with a large hammer were sufficient to upset the wife but did not budge the displacer.

I then purchased a pair of vise-grip (mole-grip) pliers made to remove oil filters http://www.harborfreight.com/locking-oi ... 66568.html
One good tightening and one good whack with a huge brass mallet on the handle of the pliers got the displacer turning, a few more whacks and it was free.

I rotated it anticlockwise, looking up from beneath the displacer, to unlock it. Looking at the locking nubs on the displacer, they appear to have ramps on both ends, so if the subframe has similar tabs with entry and exit ramps then it would not matter which direction you rotate the displacer. If the subframe has tabs with a stop at one end, then it matters. Anticlockwise from beneath is all I need to know.

Next: cut away the old hose and install new fittings.
