All 348 pages of this Case IH DC132 Disc Mower-Conditioner Service Manual are built around one job: getting your center-pull mower back to factory spec, from implement PTO to cutter bar. Open it to hydraulic schematics with full conditioner circuit routing, wiring diagrams covering the complete electrical system, and page after page of exploded views across every major subassembly. You also get torque tables, lubrication specs with grease fitting locations, chain service procedures, and a dedicated section on Attachments and Headers. The slip clutch calls for 2034 N·m (18,000 lb·in) breakaway torque; replace friction discs before wear clearance falls below 1.6 mm. No more chasing that rattle with worn-out guesses. Jump straight to the spec with bookmarks and keyword search; open it on your phone before the first wrench turns.

Case IH DC132 Common Problems This Manual Covers
Case IH DC132 slip clutch smokes and burns out, machine wraps up after heavy cutting p. 67
Remove and disassemble the slip clutch. Measure friction disc thickness; replace both discs when worn below 1.6 mm (1/16 in) per page 67. Static breakaway torque after reassembly must reach 2034 N·m (18,000 lb in). Inspect spring plates for heat bluing before rebuilding; if heat damage shows, replace the full friction disc set.
Manual Section: Implement Power Take Off (PTO)Drive hub shears frangible splines after hitting a field obstruction, cutter bar locks up p. 180
Inspect the disc drive hub for sheared frangible splines (standard shear protection per page 17). Remove the disc and check the retaining bolt; replace the bolt if it has loosened even slightly per page 180. Torque the new hub retaining bolt to 203 N·m (150 lb ft). Inspect adjacent discs for bending or cracking before returning to service.
Manual Section: Attachments/HeadersDiscs drag or bind in the cutter bar after skipping annual bearing changes p. 180
Check each disc for up-and-down movement; normal travel is 1.52 mm (0.060 in) per page 180. Any disc that binds or moves sloppy is telling you bearings are gone. Pull the disc hub, inspect for contaminated gear oil, and replace all worn bearings. Reinstall and torque hub retaining bolts to 203 N·m (150 lb ft).
Manual Section: Attachments/HeadersConditioner belt slips, squeals, or leaves hay uncrimped after extended field use p. 273
Adjust conditioner belt tension first: the tension spring should measure 279 mm (11 in) per page 273. If the belt shows glazing, cracking, or fraying, replace it. Check pulley alignment and clean any debris from the belt path before reinstalling. A misaligned pulley will wear out a new belt within one season.
Manual Section: Attachments/HeadersKnives wear unevenly or fail to cut cleanly after a full season of mowing p. 186
Inspect all 20 knives (10 discs, 2 per disc) for wear, bending, and cracking. At the closest pass, adjacent knife clearance must stay within 3 mm (1/8 in) of the front measurement per page 186. Replace any disc that is bent or cracked per page 173. Torque disc retaining bolts to 113 N·m (83 lb ft) on reinstall.
Manual Section: Attachments/HeadersFrequently Asked Questions
What are the torque specifications for the Case IH DC132 slip clutch clamp bolts?
The two 1/2 inch x 3 inch Grade 8 cap screws and locknuts at the rear of the slip clutch should be torqued to 87 N⋅m (64 lb ft). It is important not to overtorque, as the locknut is Class C and limited to this specification. This procedure is detailed in Section 31, Chapter 3, page 71.
How to replace burning clutches on Case IH DC132?
To replace burning clutches, first remove the shielding over the slip clutch. Disassemble the clutch by removing the two cap screws and locknuts from the clamp hub, then loosen the six cap screws around the clutch housing and remove internal components. Discard the worn friction discs and replace them with new ones during reassembly, as detailed in Section 31, Chapter 3, pages 68-70.
What are the replacement specifications for Clutches?
For the slip clutch, friction discs require replacement if the clearance between the pressure plate tangs and housing is less than 1.6 mm (1/16 in). The disc spring should be replaced if it shows discoloration, cracking, or if its height is less than the specified range of 10.2 - 10.7 mm (0.400 in - 0.420 in). New cap screws and nuts are recommended for reassembly. These specifications are found in Section 31, Chapter 3, pages 67 and 69.
What are the replacement specifications for Bearings?
All worn or pitted bearing cups and cones should be replaced. If a gearbox is contaminated with debris from an internal failure, all bearings within that gearbox must be replaced. For drive shaft bearings, if one bearing has failed, the entire bearing assembly is considered a matched set and must be replaced. This information is consistently stated across various sections, including Section 00, page 19, and Section 58, Chapter 7, page 324.
