so with work to the front of the car finished for the time being, it was time to turn my attention to the rear, and the wonderful Citroen rear torsion bar beam.
Now, the car had been sat in Neil’s garage for four years, so we knew it wasn’t going to be easy. The brake unions were jammed solid, so I cut the brake lines, I was originally hoping to keep the standard lines, but this forced my hand. re-plumb or braided lines to come, but they could wait!
I had the rear of the car on axle stands, so placed a Saxo jack under each end of the rear beam, undid the four fixing bolts, and let the beam down to the ground. It was ready to go home for surgery! (It wasn’t that easy, but I won’t bore you with all the details!)
Now anybody who knows about French Torsion beams will know they are a sod to dismantle, and this was no different! We ended up letting the torsion bars soak in WD-40 for over a week, with litte difference. I borrowed a slide hammer, which broke, and then tried the socket, washer and bolt ‘puller’ method, that stripped the bolt threads (luckily the torsion bar threads were ok.) Then after being told to ‘batter the hell out of the bars’ felt this was the only way to make progress.
So Dad & I got the burner out, we threaded a bolt all the way in the torsion bar to clout, heated the trailing arm up, rested the whole beam on the kerb outside the house, and proceeded to hammer like never before … and it eventually came away in to two pieces! We repeated this process with every bit where the torsion bar was lodged solid and it eventually all came apart … with the help of the lump hammer!
The whole beam was stripped of paint and rust, re-painted, and with new bushes, spacers and seals bought from my local Citroen dealership, the beam was put back together.
Whilst the beam was off the car I decided to clean all the surface rust off from underneath, clean it up, remove the spare wheel cage (the spare wheel will be relocated inside the car,) remove the extra exhaust hanger and remove all te ABS gubbins. I also wanted to give underneath a good painting and decided on POR-15 chassis black from Frost, two coats of base coat and one coat of top coat, this stuff dries seriously hard! so hard that the paint brush was useless inbetween each coat and I went through six! brushes doing the boot floor and rear beam.
and with the painting done, it was time to put the beam back on the car, new poly bushes put in at this point.
Whilst the petrol tank was off the car, you need to move it to ease removal of the beam, I removed all the probably stagnant fuel and gave it a swill out.
