Detailed technical specifications of the transmission (Audi 100 C3)

Table of contents: Adjustment data ↓ Gear ratios ↓ Gearbox oil ↓

Until January 1988, depending on the configuration, Audi "100" cars were equipped with a five-speed gearbox with five gears and one reverse gear with synchronizers on all forward gears. The gearbox is combined with a differential and final drive. Gear shifting is performed by a lever on the body floor.

Gearbox type: 013 with index 3T or HE, 093 with index 30.

Adjustment data

Axial clearance between the end face of the locking ring and the end face of the synchronizer gear ring, mm:

nominal:

synchronizers of I and II gears and V gear 1.10-1.70;
synchronizer III and IV gears 1.35-1.90;

minimum acceptable (when worn out): 0,50.

The axial clearance of the IV gear of the secondary shaft is selected by selecting the thickness of the retaining rings. Spare parts are supplied with support rings of thickness 2.35, 2.38; 2.41, 2.44 and 2.47 mm.

The axial clearance of the 3rd gear pinion of the secondary shaft is selected by selecting the thickness of the retaining rings. Spare parts are supplied with retaining rings with a thickness of 1.50 and 1.60 mm.

Axial clearance of the IV gear of the primary shaft, mm 0.10-0.40. It is selected by selecting the thickness of the thrust washer. Spare parts are supplied with thrust washers with a thickness of 3.47, 3.57 and 1.67 mm.

Depth of insertion of the speedometer drive pinion relative to the end face of the differential box (KP type 013), mm 1.40.

Adjustment of the distance between the differential axis and the end face of the main gear drive pinion, which determines the contact of the working surface of the main gear drive pinion teeth, is achieved by placing adjusting rings between the rear bearing of the secondary shaft and the wall of the gearbox housing (see diagram). Thickness of adjusting collars supplied as spare parts, mm 0.15; 0,20; 0.25, from 0.10 to 1.20 with an interval of every 0.10 mm.

Adjustment of the differential bearing preload and the lateral clearance between the teeth of the main gear is performed by placing adjusting rings between the bearing and the clutch charter.

Preload of differential bearings, mm: 0.40.

The thickness of the adjusting rings supplied as spare parts is 0.15, 1.20, from 0.20 to 1.00 mm with an interval of every 0.10 mm.
