0000001801 M-CSD ADJUSTMENT

M-CSD adjustment 1. Fixing intermediate lever screw (A) [roller (E) must not contact intermediate lever (D)] (1)Hold the control lever (C) in the idling position. (2)At this time, adjust screw (A) so that it is horizontal and the clearance between screw (A) and the control lever (C) is L1. Then, fix using nut (B). 2. Fixing the M-CSD stopper (I) Pull the CSD lever (F) in the direction X until it contacts the stopper (I) and tighten the socket head bolt (J) when the timer advance angle is L2. 3. Screw (G) adjustment Pull the CSD lever (F) in the direction X until it contacts the stopper (I) and adjust the screw (G) so that the control lever shim thickness is L3. Then, tighten nut (H).

(b) 4.248 Engines (4 Ring)
**Spring Loaded Conformable Scraper - above gudgeon pin.Internally Stepped Compression - third groove.*Internally Stepped Compression - second groove.Chrome Insert Barrel Faced Compression - top groove.When fitting sealed power rings, ensure that the ends of the spring loaded segment butt together and do not overlap.**Some earlier A4.248 engines had a sealed power scraper ring fitted in the 4th groove. *On some earlier A4.248 engines rated up to 2,000 rev/min, the second compression ring is plain cast iron.Some later engines, rated up to 2,000 rev/min, have internally stepped chrome faced rings in both 2nd and 3rd grooves.When fitting internally stepped compression rings, ensure that the step is towards the piston crown.When fitting the spring loaded conformable scraper ring, ensure that the latch pin enters both ends of the spring. With the ring gap diametrically opposite to the latch pin, position the oil control ring over spring correctly located in annular groove of ring, i.e., between the oil control ring and the bottom of the ring groove in the piston.(c) 4.248 Engines (3 Ring)
Chrome Faced Spring Loaded ConformableScraper - above gudgeon pin.Internally Stepped Taper Faced Compression - second groove.Molybdenum Faced Internally Stepped Barrel Faced Compression - top groove.When fitting the spring loaded conformable scraper ring, ensure that the latch pin enters both ends of the spring. With the ring gap diametrically opposite to the latch pin, position the oil control ring over the spring correctly located in the annular groove of ring, i.e., between the oil control ring and the bottom of the ring groove in the piston.When fitting the internally stepped compression rings in the second and top grooves, ensure that the "step" is towards the piston crown.(d) T4.236 Engines (see Fig. F.6)
F6Chrome Faced Spring Loaded Conformable Scraper - above gudgeon pin.Cast Iron Taper Faced Compression - second groove.Molybdenum Faced Wedge Compression - top groove.When fitting the spring loaded conformable scraper ring, ensure that the latch pin enters both ends of the spring. With the ring gap diametrically opposite to the latch pin, position the oil control ring over spring correctly located in annular groove, i.e., between the oil control ring and the bottom of the ring groove in the piston.When fitting the compression rings, ensure that the manufacturers mark is towards the piston crown.(e) 4.236 Engines fitted with cast iron liners
Slotted Scraper - below gudgeon pin.Slotted Scraper - above gudgeon pin.Internally Stepped Compression - third groove.Internally Stepped Compression - second groove.*Chrome Faced Compression - top groove*With later combine engines, a plain cast iron ring is fitted in the top groove. This plain ring is completely interchangeable with the earlier chrome faced ring. When overhauling combine engines, the later plain ring should always be fitted (in engine sets). From Engine No. 236U68569 fitted to combine applications, some piston ring packs have been altered from five to four rings. The two slotted scraper rings fitted in the forth and fifth grooves have been replaced by one conformable chrome faced ring in the fourth groove only, leaving the
