Book Excerpt: 1980-1981 Suzuki GS1100 Repair Manual ENGINE

This chapter provides complete service and overhaul procedures for the GS1100 TSCC engine. Refer to Chapter Five for transmission and clutch repair procedures. All engine upper end repair, including camshafts, cylinder head and cylinder block, can be performed with the engine installed in the motorcycle. Engine removal is necessary to perform repair on the crankshaft, transmission and certain components of the gearshift mechanism. Refer to Table 1 for all engine torque specifications. Tables 1-7 are located at the end of the chapter.
ENGINE LOWER END It is necessary to split the crankcase to gain access to the crankshaft, connecting rods, transmission and inner gearshift components. The following procedures represent a complete step-by-step process that should be followed if an engine is to be completely reconditioned. However, if you are replacing a known failed part, the disassembly need only be carried out until the failed part is accessible. Further disassembly is unnecessary as long as you know that the remaining components are in good condition and that they were not affected by the failed part. DISASSEMBLY

1. Perform the complete engine removal procedure as outlined in this chapter. Several preliminary disassembly steps are performed during engine removal.
2. Remove the cylinder head, cylinder block and pistons as described in this chapter, if not previously removed.
3. Remove the screws securing the ignition cover and remove the cover (Figure 207).
4. Refer to Chapter Five and remove the clutch and external gearshift mechanism, if not previously removed.
5. Remove the 3 screws securing the signal generator unit to the crankcase and remove the unit (Figure 208). Disengage the ignition wires from under the retaining clips secured to the oil sump.
