New for the 2017-2018 plow season is the introduction of BOSS D-Force. Available as an option on new truck plow purchases, this option allows the user to maintain constant hydraulic down force to improve scraping performance while backdragging. D-Force will be available for all new straight-blade truck plows (excludes EXT, Trip-Edge, and Heavy-Duty plows) and will not be retrofittable to existing plows. 

1. 1. Remove the ½” Nylon Lock Nut from the Eye Bolt that holds the top of the spring to the plow. Start with the outer springs first as these will need to be removed before the inner springs. 
2. 2. Once the Lock Nut is removed, lower the Eye Bolt until it is no longer through the hole on the top of the plow. (Note: The entire coupler tower may need to be lowered in order to remove the springs. Use a jack to support the coupler tower, raise the kickstand on the plow, and safely lower the coupler tower until the springs can be removed).
3. 3. Rotate the spring in order to remove it from the rib in the Push frame Attachment Bar. Once the outer springs are removed, repeat the process for the inner springs. Affected hardware is recommended to be replaced at the time of spring replacement. 

4. 4. For replacement, begin by installing the Eye Bolt onto the end of the spring. Install the Push Nut Retainer onto the Eye Bolt (tabs must be facing away from the Eye Bolt). Hook the springs through the holes in the Push frame Attachment Bar and rotate springs up until Eye Bolts can be reinstalled through the top of the plow.
5. 5. Once the Eye Bolts are inserted through the plow, install the Flat Washer and the Nylon Lock Nut.
6. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring.

1. 1. To start, support the Coupler Tower with a jack and/or jack stands. For HTX-V, remove the two ½” Nylon Lock Nuts from the Eye Bolts that hold the trip springs in place. 
2. 2. Once Lock Nuts are removed, slide the Eye Bolt out of the hole in the Push frame and rotate the spring out of the hole in the Center Section.

3. 3. For replacement, begin by installing the Eye Bolt onto the end of the spring. Install the Push Nut Retainer onto the Eye Bolt (tabs must be facing away from the Eye Bolt). Hook the springs through the holes in the Center Section.  Align the Eye Bolts through the holes in the Push frame. Secure the Eye Bolts to the Push frame using ½”Flat Washers and ½” Nylon Lock Nuts.
4. 4. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring. 

1. 1. For V-XT and DXT models, the process is similar. Again, support the Coupler Tower with a jack and/or jack stands. Remove the (4) 5/8” Top Lock Nuts from the trip springs. Slide the Eye Bolts out of the back of the Push frame. (Note: Lowering of the Coupler Tower may be necessary to remove the Eye Bolts.)
2. 2. Rotate the springs to remove them from the Trip Spring Yoke.

3. 3. Reinstall the new springs onto the Trip Spring Yoke. Hook an Eye Bolt to the end of each spring and pass them through the back of the Push frame. Secure the Eye Bolts with Flat Washers and Top Lock Nuts. 
4. 4. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring.
