Abstract

A mounting assembly for mounting a diesel oxidation catalyst (DOC) system within a work vehicle may generally include a support bracket having a first side and a second side. The mounting assembly may also include a mount plate configured to be coupled to the first side of the bracket. The mount plate may include first and second plate walls and may define an elongated slot through the first plate wall. Additionally, the assembly may include a retention band configured to at least partially wrap around a housing of the DOC system between a first end configured to be coupled to the mount plate and a second end configured to be coupled to the second side of the support bracket. The mount plate may be configured to be moved laterally relative to the support bracket to allow the retention band to be tightened and loosened around the housing.

First claim

What is claimed is:

1. A method for mounting a diesel oxidation catalyst (DOC) system at an under-hood location of a work vehicle using a mounting assembly including a support bracket, a mount plate and a retention band, the support bracket extending between a first side and a second side disposed opposite the first side, the mount plate being configured to be coupled to the first side of the support bracket and including a first plate wall configured to extend adjacent to the first mounting surface and a second plate wall configured to extend adjacent to the second mounting surface, the method comprising:
positioning a housing of the DOC system adjacent to the support bracket;
coupling one end of the retention band to the second side of the support bracket;
coupling an opposite end of the retention band to the mount plate; and
moving the mount plate laterally relative to the first mounting surface in order to tighten the retention band around the housing.

2. The method of claim 1 , wherein a second fastener opening is defined through the second mounting surface of the support bracket and the mount plate includes a wall opening defined through the second plate wall that is configured to be aligned with the second fastener opening, wherein moving the mount plate laterally relative to the first mounting surface comprises tightening a second fastener extending through the second fastener opening and the wall opening such that mount plate is moved laterally relative to the first mounting surface in a direction towards the second mounting surface.

3. The method of claim 2 , wherein the first plate wall of the mount plate defines an elongated slot configured to be aligned with a first fastener opening defined through the first mounting surface of the support bracket, the method further comprising:
inserting a first fastener through the elongated slot and into the first fastener opening; and
tightening the first fastener relative to the first wall and the first mounting surface after the second fastener is tightened.

4. The method of claim 1 , wherein the mounting assembly further comprises a support leg extending outwardly from the support bracket between the first and second sides, wherein positioning the housing of the DOC system adjacent to the support bracket comprises positioning the housing adjacent to the support bracket such that the housing is supported vertically by a bottom portion of the support leg.
