ISM, ISMe, and QSM11 – 011-025   EGR Connection Tubes

Before installing the v-band clamp, coat the clamping surface with high temperature anti-seize compound.

NOTE: It is very important to perform the following installation procedure in the order listed. This will prevent early life wear out of the hoses.

Install a hose (2) onto each end of upper EGR connection tube (3).

Slide two hose clamps loosely over both hoses.

Install the upper EGR connection tube (3) with the hoses onto the engine and install one end of the hose (2) onto the EGR mixer inlet.

Hand start the capscrew (5) on the bracket.

Slide one end of the EGR connection tube (1) into the other end of the hose (2).

Slide the v-band clamps (4) over the EGR cooler connection.

Align the v-band clamp (4) over the connection and finger tighten only (do not torque)

Tighten the upper EGR connection tube mounting capscrew (5).

Rotate and adjust the EGR connection tube (1) so the hose (2) is straight between the ends of the EGR connection tubes (1) and (3).

Tighten the v-band clamp (4).

Position the hose evenly between the hose stops (if available) on the EGR connection tubes (1 and 3).

Position the hose clamps loosely and evenly between the hose bead (if available) and the edge of the hose or 16 mm [5/8 in] from the edge of the hoses.

Tighten the hose clamps.

Remove the protective caps and heavy tape.

Install the differential pressure sensing tubes onto the EGR venturi tube and the EGR differential pressure sensor adapter, but do not torque. Refer to Procedure 011-026 in Section 11.

Install and tighten the EGR venturi tube mounting stud.

Position the rear hose evenly between the EGR connection and EGR venturi tube. Position the front hose evenly between the EGR venturi tube and the EGR mixer inlet.

Tighten the EGR connection hose clamps.
