Note
 
 

 
 
The modified oil pan (1) is installed on models 107, 116 and 123 since October 1979 and model 126 since begin of series.
For this purpose, the rear 3 fastening threads on cylinder crankcase have been changed on both sides from M 6 to M 8 mm.

This modified oil pan is screwed to cylinder crank­case at the rear with 6 screws M 8 x 95 mm, formerly 4 screws M 6 x 40 mm and 2 screws M 6 x 25 mm.
 
 

 
 
On model 126 the modified oil pan is screwed to cylinder crankcase together with supporting tray (arrow) by means of 6 screws M 8 x 110 mm.

If a modified oil pan is installed in the course of repairs, the respective threaded bores in cylinder crankcase should be enlarged from M 6 to M 8 mm.
 
 

 
 
In the event of repairs, use radial sealing ring 000 997 90 41 (yellow-brown) with a projection of 0.5 mm on both sides, except when a new or newly ground crankshaft with new crankshaft bearings is installed. In such a case, use radial sealing ring
000 997 69 41 (graphite-grey) with a projection of
1  mm on both sides. This will protect the rear bearing journal of crankshaft against being overheated under influence of a low crankshaft bearing play and excessive pressure against yellow-brown radial sealing ring.

Installation, all models
m110 - 0045-1.jpg
 
 
1    Clean parting surface on cylinder crankcase and oil pan.
2   Renew rear radial sealing ring in oil pan and work in.
 
 
Note: Do not install radial sealing ring 000 997 90 41 (yellow-brown) in engines which are provided with a new or refinished crankshaft and new crankshaft bearings in the event of repairs.
 
 

 
 
3 To arrive at an overlap, cut off radial sealing ring approx. 0.5 or 1.0 mm above parting surface. Use self-made gauge for this purpose.

4   Provide radial sealing ring with engine oil.
5   Coat parting surface of oil pan with sealing com­pound.
6   Install oil pan and screw-on lightly at front and rear with 2 screws each.
