Case IH 2142, 2152, 2162 Draper Header Common Problems This Manual Covers
Case IH 2152 left draper belt slows, stalls intermittently when entering crop p. 133
Inspect the idler roller bearings on the affected draper deck. Pull the roller assembly and check for rough rotation, contamination, or pitting. Press replacement bearings to 13 to 14 mm (0.51 to 0.55 inch) depth and seals to 12 to 13 mm (0.47 to 0.51 inch) per page 133. Torque the roller bolt to 95 Nm (70 foot pounds).
Manual Section: Draper DriveDraper belt won't hold tension, slips or rides off rollers during operation p. 145
Verify center draper tension first: the spring retainer (5) must sit flush with the outside housing per page 145. If tension checks out, remove and inspect the drive roller bearings. Press replacements to 13 to 14 mm (0.51 to 0.55 inch) depth and torque the drive roller bolt to 95 Nm (70 foot pounds) per page 136.
Manual Section: Draper DriveHeader won't lower far enough to pick up downed or short-stemmed crop p. 30
Check the troubleshooting index at page 30 under Header Flotation for the full diagnostic sequence. Verify hydraulic system pressure at the piston pump compensator, which should hold 3000 psi at full demand per page 208. Then inspect the flex linkage for bent or seized components restricting downward travel, starting at page 314.
Manual Section: TroubleshootingKnife drive belt slipping or chattering, uneven p. 63
Inspect the knife drive belt for wear, glazing, or cracking and check belt tension and sheave alignment. Examine the wobble box drive and its mounting per the Knife Drive section beginning on page 63. Replace a stretched, chattering, or damaged belt and re-tension to the factory specification before returning the header to service.
Manual Section: Knife DriveFrequently Asked Questions
Torque specs for mounting bolts on Case IH 2162 Draper Header reel drive?
The manual provides torque specifications for various bolts within the reel drive assembly. For the motor assembly, bolts should be torqued to 95 to 108 Nm (70 to 80 foot pounds). Additionally, bolts securing the U-joint assembly and the left reel to the reel drive shaft should be torqued to 102 to 115 Nm (75 to 85 foot pounds).
What are the replacement specifications for End roller idler bearings?
When installing new idler roller bearings, the bearing must be pressed into the tube 13 to 14 mm (0.51 to 0.55 inch) from the outside edge of the tube. The new seal should be pressed in 12 to 13 mm (0.47 to 0.51 inch) from the outside edge of the tube, and the area (A) should be filled with 8 cc of grease before installation.
What are the replacement specifications for Draper belt tensioners?
For draper belt tensioning, the manual refers to the "Draper Tension Decal" for proper adjustment. This decal visually indicates to "TURN BOLT (1) TO TIGHTEN DRAPER UNTIL WHITE INDICATOR BAR (2) CROSSES SLOT (3) AND FILLS INBOARD HALF OF SLOT." For specific numerical tension values, the manual directs to the Operator's Manual.
How do you fix case IH 2152 left draper belt slows, stalls intermittently when entering crop?
Inspect the idler roller bearings on the affected draper deck. Pull the roller assembly and check for rough rotation, contamination, or pitting. Press replacement bearings to 13 to 14 mm (0.51 to 0.55 inch) depth and seals to 12 to 13 mm (0.47 to 0.51 inch) per page 133. Torque the roller bolt to 95 Nm (70 foot pounds).
