Does anyone have a drawing of the removal gear for stripping down plunger rear suspension,I know you can buy the items as advertised in the magazines but a length of screwed rod and a bit of work seems a better option for me.Whats your prefered method , it a 1949 plunger A7. Thanks for any replys. Alan

I didn't use a tool at all for both removal and reassembly. My procedure was to remove: release all the pinch bolts and carefully wedge open this includes the wheel spindle carrier. Tap out the shaft from the bottom upwards using a socket and extension to get it moving and then a wooden dowel. Once the shafts are out carefully put your weight on the top spring and bring it out he side, the bottom of the frame will need chocking to do this. Assembly is the reverse use a wooden dowel to line the parts up for the shaft to be tapped in. I managed to do this OK and not scratch any paint!

I used a similar method as Stu and removed mine without a tool. I am attempting to attach a picture of the tool with this post but not sure what I am doing.  If it doesn't appear I will try again.

Russ, Do you have any details of the plunger tool I know I can buy one for £30.00 but maybe I can make one out of some spare bit I already have. Has anyone else got any details of the toll please.

I more or less did the same as Stu, apart from I used a long ratchet clamp to compress the spring instead of just pushing on it (yeah, ok, I'm a wimp  smile).
  They are not compressed like a car spring, which can take your head off if they get away from you.

Alan,
no I don't have any details on the plunger removal tool as I haven't attempted to put mine back together.  Having said that, I don't think it will be difficult to make one.  It is simply a length of threaded rod with a nut on each end, the bottom one can be fixed in position if you like, a spacer on the top to keep the top nut above the frame whilst you tighten it and two pieces of flat bar with a slot to allow them to be slid through the threaded rod  The slot allows you to pull them out once the suspension is in place in the frame and the top nut has been undone to release the tension.  Sorry for the delay in replying and hope this made sense.

Russ.
