Front O/S torsion bar adjustment.

[Cyprusnoddycar]

Greetings from Cyprus,
My R4 is running well, although it handles really badly due to the front O/S (driver side) torsion bar needing adjustment. I did the correct measurements and it is 3 cm lower than the N/S ! So I have ordered the correct adjusting tool from De Marco in Italy. Although I am not sure if I have the fixed non adjustable type of torsion bar ? It's not very clear in the Haynes manual. Thanks Kevin

Since the production from 1961 every front and rear torsion bar (left and or right) is adjustable, there are NO fixed non adjustable versions.

On the first generations of 4L, the torsion bars are adjusted using a lever attached to the rear end of the bar, which has 4 or 5 possible tightening positions on the chassis. The end of the bars (where the lever or the axle is attached) is hexagonal. This adjustment system is not very precise, but still adjustable.

From the end of 1968 (1969 models) and until 1978, the ends of the bars are no longer hexagonal but notched. The height under the body is achieved by modifying the notching of the bars in the axle and the anchoring lever and the "fine" adjustment is achieved using a cam pressing more or less on the anchoring lever of the torsion bar.

Finally, models since October 1978 have a fixed anchor bearing at the chassis level. The adjustment is therefore made only from the notching at the end of the bars, this thanks to an improvement in the production and control of the bar calibration. This system is optimal (for an R4 of course), a shift of one notch modifies the height under the hull by a fixed value.
