When installing seals no. 17, apply a light coat of Molykote 111 on seal lips. Prior to installation, place bearings no. 15 into a container filled with oil, previously heated to 75°C (167°F). This will expand bearings and ease their installation. Reinstall counterweights no. 16 using a press and take care to align index marks previously traced. Crankshaft and Counterbalance Shaft 787 RFI and 947 DI Engines Install crankshaft no. 3 first in crankcase. After crankshaft installation, install counterbalance shaft no. 13. Make sure to properly index crankshaft and counterbalance shaft by gear aligning marks. CAUTION: Marks on the crankshaft and counterbalance shaft must be aligned, otherwise engine will vibrate and premature wear will occur. F00D0PA 1 787 RFI ENGINES 1.

Section 04 ENGINE (2-STROKE) Subsection 05 (BOTTOM END) F06D1OA 1. Seal in place 1 Air Compressor 947 DI Engines Refer to ENGINE MANAGEMENT for procedures. Crankcase All Engines Crankcase halves are factory matched and therefore, are not interchangeable or available as single halves. 717 and 787 RFI Engines Rotary valve shaft must be installed in crankcase before closing halves. CAUTION: Before joining crankcase halves, make sure that crankshaft gear is well engaged with rotary valve shaft gear. 717 Engines Temporarily install armature plate to align crankcase halves with each other. CAUTION: Using different types of oil may reduce engine component life. All Models IMPORTANT: When beginning the application of the crankcase sealant, the assembly and the first torquing should be done within 10 minutes. It is suggested to have all you need on hand to save time. NOTE: It is recommended to apply this specific sealant as described here to get an uniform application without lumps. If you do not use the roller method, you may use your finger to uniformly distribute the sealant (unlike the Drei Bond sealing compound, using a finger will not affect the adhesion). Use the silicone-based Loctite 5910 (P/N 293 800 081) on mating surfaces. NOTE: The sealant curing time is similar to the Loctite 518 without using the Primer N. CAUTION: Do not use Loctite 515 or 518 to seal crankcase. Do not use Loctite Primer N with the Loctite 5910. Using these products or non silicone-based sealant over a previously sealed crankcase with Loctite 5910 will lead to poor adhesion and possibly a leaking crankcase. These products are chemically incompatibles. Even after cleaning, the Loctite 5910 would leave incompatible microscopic particles. Use a plexiglass plate and apply some sealant on it. Use a soft rubber roller (50 - 75 mm (2 - 3 in)) (available in arts products suppliers for printmaking) and roll the sealant to get a thin uniform coat on the plate (spread as necessary). When ready, apply the sealant on crankcase mating surfaces. 148 smr2004-Complete Line Up F12R17A
