2 B-1. General Information Tables provided in this appendix list torque values for hardware on TCM s aircraft engines. Refer to appropriate manufacturer s accessory overhaul manuals for specified torque on accessories. Table B-1 is for bolts, nuts, screws, driving studs, and pipe plugs; Table B-2 is for fittings, Table B-3 is for hose fittings, and Table B-4 lists specific torque values. The torque values provided in Table B-4 must be used for the specific application. WARNING Torque values listed are for use with clean 50 weight aviation engine oil applied to the threads, unless otherwise specified in Table B-5 which lists specific torque values for non-lubricated hardware. Prior to torquing any hardware, unless otherwise specified, apply SAE 50 weight aviation oil to hardware listed in Table B-1 through Table B-4. If an application is not listed in the specific torque limits (Table B-4 and Table B-5), the general torque limits (in Table B-1 through Table B-3) must be used. B-1.1. Torque Tips WARNING Before installing nuts and bolts, verify the fastening hardware is lubricated where necessary as instructed. Inspect all fasteners for proper plating and thread form. Failure to verify a fastener s serviceability or to correctly lubricate the fastener as directed prior to installation and torquing will result in the fastener not being properly pre-loaded. Subsequent failure of the fastener may occur. WARNING The use of sealants or lubricants other than those specified by TCM on mating threads and between mating surfaces can cause incorrect torque application and subsequent engine damage or failure. Check Table B-4 and Table B-5to verify whether the hardware to be torqued requires a specific torque or treatment other than those for general hardware sizes listed in Table B- 1 through Table B-3. Before torquing the hardware, verify that the hardware size is correct. The accuracy of any torque indicating wrench depends on a smooth application of force and current calibration traceable to the National Bureau of Standards. If cotter pin holes must be aligned, set the torque wrench at the low limit and tighten the nut to the first hole beyond this torque, but do not exceed the maximum torque limit specified. This torquing procedure must be followed for all applications requiring cotter pin hole alignment except for connecting rod nuts. B-2 TSIO-550 Permold Series Installation and Operation Manual

3 If a nut slot cannot be aligned with a cotter pin hole within the specified limits, substitute another serviceable nut to attain alignment. If the cotter pin hole in a stud lies beyond the nut slots, when the nut has been torqued properly, check the stud for proper installation or for backing out. Check studs for necking. Check the part for reduced thickness resulting from wear or incorrect part. B-2. Cylinder Torque Procedure Proper cylinder installation requires the bolts be torqued in multiple stages. Cylinder base stud threads, through bolt threads and nuts must be lubricated with clean 50 weight aviation oil. Through bolt nuts at cadmium plated washers require a lower torque value to achieve the same through-bolt pre-load since the lubricity of the cadmium plating reduces joint friction. Procedure 1. Torque cylinder base nuts to ½ of the specified torque value for the fastener. 2. Torque the cylinder through bolt nuts and cylinder base nuts to the specified value for the cylinder base stud nuts. Through bolt nuts must be torqued on both sides of the engine, even if only one cylinder is being installed. WARNING Failure to torque through bolt nuts on both sides of the engine can result in a loss of main bearing crush with main bearing shift and subsequent engine failure. NOTE: Through-bolt nuts P/N and have been superseded by P/N Nut P/N is a flanged six-point (hex) nut requiring a torque value of inch-pounds. Nut P/N is a flanged sixpoint (hex) nut requiring a torque value of inch-pounds. At engine overhaul, all P/N and P/N flanged through bolt nuts must be replaced with flanged twelvepoint nuts. If replacing P/N and P/N with in less than a complete set prior to engine overhaul, torque the twelve-point nuts to the torque value of the original fastener (P/N or P/N ). 3. Torque through-bolt nuts on both sides of the engine to the specified torque value. 4. For engines which incorporate the seventh cylinder deck stud, install the seventh stud cylinder bracket and conical stud nut. Torque the stud nut to the value specified for the fastener.

4 B-3. Torque Wrench and Extension Calculations Torque wrenches measure the force applied to the fastener on the axis of the square drive socket adapter. Figure B-1. Torque Wrench Straight extensions, including wobble extensions up to 15 degrees, which extend the square drive length, do not alter the amount of force applied to the square drive enough to cause concern. An offset adapter may be used with a torque wrench without affecting applied torque if the extension is positioned at a 90 degree angle in relation to the square drive adapter. In any other orientation, the extension alters the force applied to the fastener. Figure B-2. Drive extensions Apply the formula below to determine the appropriate torque wrench setting when using an extension: Where: T S= A + B x A S = desired torque setting or reading T= torque applied at square drive adapter A= length of handle in inches B= length of extension in inches B-4 TSIO-550 Permold Series Installation and Operation Manual

5 Figure B-3. Extension increases applied torque Examples in Figure B-3 and Figure B-4 indicate the torque at the fastener may be increased or decreased by an extension. The two examples in Figure B-3 increase the force applied to the fastener but the position of the extension in Figure B-4 reduces the effective length of the handle. The formula is the same but variable B is a negative number in Figure B-4. Let s assume the torque wrench has an effective length of 12 inches and the extension measures six inches from the center of the drive adapter to the center of the wrench. If we need to torque a nut and bolt to 45 inch-pounds, we set the dial on the wrench in Figure B-3 to 30 (45 (12+6) x 12). The same torque wrench dial, used with the extension in Figure B-4 must be set to 90 (45 (12-6) x 12) to apply 45 inch pounds of torque to the same nut and bolt. Figure B-4. Extension decreases applied torque TSIO-550 Permold Series Installation and Operation Manual B-5

If cotter pin will not enter in this range, replace nut and repeat. IN NO CASE SHALL NUTS BE TIGHTENED BELOW THE MINIMUM TORQUE LIMIT OR OVER THE MAXIMUM TORQUE LIMIT. Reference the most current revision of TCM Service Bulletin SIL as applicable for special instructions for cotter pinning the 360 model engine connecting rods. Strike outer periphery of coupling band lightly to distribute load. Then tighten to in/lb. for P/N Clamp and in/lb. for P/N Clamp. Do not realign hex cap screw to suit tab washer.

Align and tension belt in accordance with TCM Service Bulletin M89-6 or current revision as applicable. Crankgear must be heated to 300 Fahrenheit, then installed on crankshaft. Ensure the gear seats tightly against the end of the crankshaft by tapping lightly with a brass hammer. CAUTION: Improper heating of the crankshaft gear will result in damage to the gear and may lead to subsequent engine failure. The instructions contained in the latest revision of the appropriate overhaul manual must be used for crankshaft gear installation.
