Section I. U.S. Army Supplement to Dana Spicer Clark-Hurth Material.
This appendix contains information for servicing the transmission. Section I contains U.S. Army supplemental information to
the vendor manual. The supplemental information includes initial setup task boxes for all maintenance tasks covered in the
vendor manual that apply to the IHMEE. The supplemental information also includes individual task headings and page
references to aid in locating the tasks in the vendor manual.
Section II contains the manufacturer's technical manual. This manual is unedited and covers multiple models of Dana Spicer
Clark-Hurth transmissions. This manual also contains parts information for Dana Spicer Clark-Hurth transmissions. Refer to
Para F-2 for details on how to use this material.
To perform a task covered in this appendix, refer to the task box for initial setup information as you would with a normal
maintenance procedure. The individual task headings have page references to aid in locating the tasks in the vendor manual.
Most pages will also include two different page numbers. The appendix page number will have the appendix letter and a page
number like the one at the bottom of this page. This page number will be used in all references made in Section I. The other
page number is the vendor material page numbering. It will be used for any references made within the vendor material.
The IHMEE uses the Dana Spicer Clark-Hurth 12.5 LHR 32821-3 transmission with a remote-mounted shift valve,
remote-mounted filter, and no brake drum. All information in Section II that does not pertain to the HR 32000 series
transmissions and all parts information should be ignored. Refer to TM 5-2420-230-24P for parts information.
