Removal (Fig. 20) 1. Park machine on a level surface, lower cutting deck, stop engine, engage parking brake and remove key from the ignition switch. 2. Remove deck covers from top of cutting deck. CAUTION Be careful when installing the idler spring. The spring is under heavy load and may cause personal injury. CAUTION Be careful when removing idler spring. The spring is under heavy load and may cause personal injury. 3. Use spring hook tool to unhook the idler spring (item 15) from the adjusting screw (item 4). 4. Remove drive belt(s) from deck pulleys. 5. Loosen flange nuts (item 11) that secure idler stop bolt (item 10) to cutting deck to allow clearance between idler arm and stop bolt. 3. Use spring hook tool to attach the idler spring (item 15) onto the adjusting screw (item 4) and shoulder bolt on idler arm. With the idler arm tensioning the drive belt, the spring hook to hook length should be from 3.250” to 3.750” (82.6 to 95.2 mm) (Fig. 21). If necessary, disconnect spring and change position of adjusting screw. When idler spring is the correct length, tighten second flange nut to secure adjustment. 4. Adjust location of idler stop bolt (item 10) so that the clearance between idler arm and idler stop bolt head is from 0.125” to 0.185” (3.2 to 4.6 mm) (Fig. 21). 5. Install deck covers to cutting deck. 6. Remove idler components as needed using Figure 20 as a guide. Note location of washers, idler spacer and screw as idler assemblies are being removed. Installation (Fig. 20) 1. Install removed idler components using Figure 20 as a guide. A. Make sure that one (1) thrust washer (item 19) is placed below the idler arm and three (3) thrust washers are placed between the idler and retaining ring location. B. Secure idler arm assembly to cutting deck with snap ring. C. If idler stop bolt (item 10) was removed from deck, make sure that it is installed in the hole that allows the stop bolt head to align with the idler arm. 2. Install drive belt to pulleys. 3.250” to 3.750” (82.6 to 95.2 mm) Figure 21 0.125” to 0.185” (3.2 to 4.6 mm) Cutting Deck Groundsmaster 4100--D Page 8 - 21 Cutting Deck
