The steering ratio with power assistance is 16.4.

Without assistance it's 19-22.5 (it might have been 22.5 on the universal model?)

On my side, there's no additional equipment; the air compressor has long since been scrapped, and the car wasn't equipped with an air conditioner to begin with. Therefore, it was decided to install the power steering pump on the right side as on a 1G, rather than the left like on some 21R-U models.

This is quite a complex setup; there's an additional roller, brackets, and the overflow tank needs to be relocated somewhere, not to mention long hoses.

Installing the Pump

Ordered a transitional plate of this shape, thickness 5 mm

But during the first fitting attempt, the plate began to bend.

Had to order another one like it and weld them together

In the end, after several fittings and adjustments, the pump found its place, and I purchased a drive belt of the required length.

Steering Reducer

The reducer fits by mounting bolts but differs in size from the old one

Therefore, the steering shaft had to be shortened by 22 mm.

Where the shaft folds due to frontal impact it's fixed only with plastic inserts that are poured in.

It requires effort; the plastic filling breaks and the shaft is shortened.

Hoses were standard ones from a 1G.

In the coming days, I'll try out the power steering while driving, but for now, I've just filled it with oil and bled the system.
