13200-91JQ0 Suzuki CARBURETOR

Keep all parts clean from contaminants. Contaminants put into the system may cause rapid wear and shortened component life.
1. Remove the carbon ring and lip from the inner surface of the cylinder liner. 2. Turn the crankshaft until two of the pistons are at bottom center. Remove the nuts and bolts (1) from the connecting rods that are at bottom center. Remove connecting rod caps (2), and put identification marks on them for installation purposes.
Do not let the connecting rods hit the crankshaft or the bottom edge of the cylinder liners when the pistons are removed.
3. Push the connecting rods and pistons away from the crankshaft until the piston rings are out of the cylinder liners. Remove the two pistons from the engine.4. Keep each connecting rod cap with its respective connecting rod and piston. Put identification marks on each piston as to its location in the engine.5. Do Steps 1 through 4 for the removal of the remaining pistons.Install Pistons & Connecting Rods
1. Turn the crankshaft until the bearing journals for the pistons to be installed are at bottom center.2. Put clean engine oil on the crankshaft journals and on the inside of the cylinder liners. Put clean engine oil on the piston rings and the connecting rod bearings.3. Move the piston rings on the pistons until the ring openings are approximately 90 degreesapart. 4. Put the piston in the cylinder liner with the "V" mark on the piston in alignment with the "V" mark on the cylinder block. Put Tooling (A) in position on the cylinder block and compress the piston rings.
If the "V" mark is not visible on the piston or the cylinder block. The piston must be installed with the valve pockets positioned toward the push rod opening in the cylinder block. Damage may result if pistons are installed improper.
5. Push the piston into the cylinder liner and out of the ring compressor. 6. Pull the connecting rod into position on the crankshaft as shown. Install connecting rod bolts (1) in the connecting rods.7. Put clean engine oil on the lower half of the connecting rod bearing. Put 4C-5593 Thread Lubricanton the bolt threads and on the surfaces of the nuts that make contact with the rod caps.
When the connecting rod caps are installed, make sure the number on the side of the cap is next to and respective with the number on the side of the connecting rod.
8. Install connecting rod caps (2) and the nuts that hold them. Tighten the nuts to a torque of 41 4 N m (30 3 lb ft). Put a mark on each nut as to its location, and tighten them 90 5 degreesmore.
Do not use an impact wrench to tighten the nuts the additional 90 degrees.
9. Perform Steps 1 through 8 for the remainder of the pistons.End By:a. install oil pumpb. install spacer plateDisassemble Pistons & Connecting Rods

Keep all parts clean from contaminants. Contaminants put into the system may cause rapid wear and shortened component life.
1. Remove the rings from the pistons with Tool (A). 2. Remove retaining ring (3), piston pin (1) and connecting rod (2).3. Remove the bearings from the crankshaft end of the connecting rod.4. See, Use Of Piston Pin Bearing Removal And Installation Tools, Special Instructions, SMHS7295-02, for more information about removal and installation of piston pin bearings. Be sure to remove the bearings from the crankshaft end of connecting rod.5. Heat the connecting rod in an oven to a temperature of 176 to 260°C (350 to 500°F). Never use a direct flame to heat a connecting rod. 6. Put 6V-3029 Spacer(11) in the base plate. Put the connecting rod on the base plate of Tooling (B).7. Put the connecting rod piston pin bearing end in the center of the port assembly of Tooling (B). Install pin (6) in the center of the bore for the connecting rod bearing.8. Install 6V-2049 Adapter(9). Put the hole in the adapter in alignment with the hole in the base plate of Tooling (B).9. Install clamp bar (10) and clamp pin (7). The old bearing is pushed out by Tooling (B) as the new bearing is installed.10. Put 5P-8645 Pusher Adapter(8) in position as shown with the taper side down. The piston pin bearing joint must be in alignment with the hole in adapter (9) and the base plate of Tooling (B).11. Install pusher (4) on adapter (8).12. Use Tooling (B) to push the new piston pin bearing (5) into the connecting rod until adapter (8) of Tooling (B) makes full contact with the connecting rod surface.13. Remove the connecting rod and the old piston pin bearing from Tooling (B).14. Check the piston pin bearing bore diameter after the bearing is installed. The correct dimension is 43.210 0.008 mm (1.7012 .0003 in). The maximum permissible clearance between the bearing and piston pin (worn) must not be more than 0.08 mm (.003 in).Assemble Pistons & Connecting Rods
1. When old pistons are used, clean the piston grooves with an acceptable ring groove Tool.2. Install the connecting rod bearings in the crankshaft end of the connecting rod. Make sure the tabs on the back of the bearings are in the tab grooves of the connecting rod and cap. Thoroughly lubricate piston pin (1) and the piston pin bearing in connecting rod (2) with clean engine oil prior to assembly. 3. Put connecting rod (2) in the piston with the bearing tab slot and number identification on the same side as the "V" mark on the top of the piston.4. Install piston pin (1) and retaining ring (3).5. For correct piston and ring clearances, see the topic "Pistons & Rings" in the Specifications Manual.6. Install the oil ring spring in the oil ring groove of the piston. The oil ring must be installed on the piston with the ring end gap 180 degrees from the oil ring spring joint. 7. Install the oil ring on the piston with Tool
