Service bulletin KTI Hydraulic PumpDC45537

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

It was discovered that several trailers escaped the Big Tex Caldwell facility with KTI pump PN DC 45537 power up / power down / gravity down manufactured with an incorrect valve body. The hydraulic system on affected trailers functions properly in the power up / power down mode. However, due to the incorrect valve body installed on some pumps, the hydraulic reservoir could overflow if operated in the gravity down mode.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
