EXHAUST ELBOW INSTALLATION

Exhaust elbows are standard on generators, optional on

engines. For installation on your engine/generator, we offer

and 90

exhaust elbows.

NOTE: Fabricated exhaust elbows or risers attached to the

exhaust manifold shall not exceed 8 lbs. when unsupported.

1. Coat only one side of the exhaust gasket with High Tack

(manufactured by Permatex Company, Brooklyn, N.Y.)

adhesive sealant. Place this coated surface against the

exhaust manifold’s exhaust port flange (the gasket should

stick to the flange without falling off).

2. Place the clamp over the elbow’s flange. Place your

exhaust elbow against the exhaust manifold’s flange so

the exhaust manifold’s flange rests snug against the

exhaust elbow’s flange with the gasket centered between

the two. Now slip the exhaust clamp over both flanges.

3. Tighten the clamp just enough so the exhaust elbow can

remain attached to the manifold and still be rotated. The

exhaust elbow discharge must be directed downward so

the mixture of raw water and exhaust gases will flow/fall

downward into the exhaust muffler which must be posi-

tioned below the exhaust elbow. There should be no loops

or rises in the exhaust hose connected between the

exhaust elbow and the muffler, as these would trap water

and possibly allow water to flow back into the engine dur-

ing starting or at shut-down.

4. Adjust the elbow by rotating it until the desired alignment

with the exhaust piping is acquired.

5. Carefully tighten the clamp between 8 to 10 lb-ft, or 24 to

35 lb-in, or 0.27 to 0.41 kg-m.

6. When the engine is started for the first time with the new

elbow, check this exhaust manifold/elbow connection for

leaks. If a leak exists, correct it immediately.

▲ CAUTION:

10 lb-ft (1.4 kg-m) Torque Limit:

approach the 10 lb-ft (1.4 kg-m) torque limit with

caution. The clamp’s threads will break if more than

10 lb-ft (1.4 kg-m) is applied to the clamp.
