What Are the Torque Specs for Vehicles

by Contributing Writer

Vehicles Motors builds the Vehicles engine and manufactures the Vehicles line of Vehicles. The Vehicles engine uses the combustion chamber and intake port to induce a swirl action increasing the burn efficiency of the air and fuel. The Vehicles engine is mainly used on Vehicles line of pickup Vehicles.

 What Are the Torque Specs for a Suzuki RM 250 Cylinder?

General Engine Specifications

The RM250 features a two-stroke single cylinder engine that produces total pistol displacement of 249 cubic centimeters. The transmission is a five-speed manual. As is common for powerful motorcycles with small engines, the RM250 produces more horsepower at higher revolutions per minute. Suzuki experimented with the engine to give it more midrange power.

2001 Improvements

In 2001 Suzuki tried to achieve better engine performance by reducing the motorcycle's weight and improving the exhaust system. The frame and rear cradle tubing were completely redesigned, and the search for lightness was extended to the engine. A two-stage, two-piece power valve replaced a one-piece exhaust valve. New valves allowed for opening over wider rpm range.

2005 Improvements

For the 2005 model, Suzuki redesigned the combustion chamber and reduced the squish area, which improved combustion efficiency and throttle response. The upper corners of the main exhaust ports were raised. These changes helped to improve power delivery at low-end and mid-end ranges.

 Torque Specs for a '98 Prelude Crankshaft

Crankshaft Assembly

A lot of things go between the engine block and oil pan that help components to go round and round, up and down. Starting from the bare block -- placed upside down -- the assembly goes thus: upper main bearing, crankshaft, main-cap-to-block dowel pins, main caps, main-cap-to-bearing-bridge dowel pins, bearing bridge, main cap bolts, oil baffle plate and baffle plate bolts. Once you have the baffle plate on, you can install the oil pickup and oil pan.

Preparing the Mains

Before you drop the crankshaft into the block, paint the bearing surfaces and crankshaft journals with assembly lube. This thick lubricant will keep things moving smoothly until you get oil flowing through the engine. Clean the bolt threads and place a few drops of lightweight oil on the threads. This oil will reduce friction between the bolt threads and block, which could easily skew torque readings by as much as 5 to 10 foot-pounds.

Initial Torquing

The H22 has five main caps, numbered 1, 2, 3, 4 and 5 from the front of the engine to the rear. While final torque for the main caps comes out to 54 foot-pounds, you'll want to use a two-step procedure to ensure even bearing loading. Start at the center cap, or cap No. 3; torque the bolts to 22 foot-pounds, then spin the crankshaft once to check for binding. Torque the bolts on cap 2 at 22 foot-pounds, then spin the crank. Proceed to cap 4, then cap 1 and finally cap 5 and torque each to 22 foot-pounds.

Final Torque

Go back through the torquing procedure, starting from the center cap -- No. 3 -- and working your way outward. Torque the caps to 54 foot-pounds, and spin the crankshaft after each adjustment. Better to find out about bearing bind now than after you get the engine put together and running. Torque the baffle bolts, oil pickup and oil pan bolts to 9 foot-pounds each. Don't forget the rear main -- the largest one that contains the rear main seal -- which bolts on from the back. Its bolts torque to 9 foot-pounds, and require a coat of liquid gasket on the threads.

The 3.8-inch bolt bolt has 45 foot-pounds of torque, and the 7/16 inch bolt has 75 foot-pounds of torque. The inner bolts connecting the crankshaft to the engine block have 75 foot-pounds of torque while the inner bolts have 65 foot-pounds of torque. The blue loctite bolt connecting the flywheel to the crankshaft has 60 foot-pounds of torque, the three bolts connecting the pulley to the crankshaft have 30 foot-pounds of torque, and the bolts connecting the pressure plat to the flywheel have 35 foot-pounds of torque.

Cylinder Head Torque Specs

The bolts connecting the carburetor to the intake manifold have 7.5 foot-pounds of torque and the bolts connecting the cylinder head to the engine block have 65 foot-pounds of torque. The inner bolts connecting the exhaust manifold to the cylinder head have 30 foot-pounds of torque while the outer bolts have 20 foot-pounds of torque. The bolts connecting the intake manifold to the cylinder head have 33 foot-pounds of torque and the bolts connecting the rocker arm stud to the cylinder head have 50 foot-pounds of torque. The bolt connecting the 13/16-inch spark plug to the cylinder head has 22 foot-pounds of torque, while the 5/8-inch spark plug has 15 foot-pounds of torque.

Engine Torque Specs

The bolts connecting the bell housing to the engine block have 30 foot-pounds of torque and the bolts connecting the distributor clamp to the engine block have 20 foot-pounds of torque. The bolts connecting the engine mount to the engine block have 35 foot-pounds of torque, the bolts connecting the fuel pump to the engine block have 30 foot-pounds of torque, and the bolts connecting the starter to the engine block have 35 foot-pounds of torque.

Drivetrain Torque Specs

The 5.7-liter Vortec engine has a peak torque of 330 foot-pounds at 2,800 rpm.
