New Holland BR7050 Common Problems This Manual Covers
Net wrap fails to start, stalls mid-cycle, or wraps intermittently p. 179
Start by checking the brake/retention assembly. Manually rotate each roller in the net-wrap drive path and feel for binding; a seized bearing here is the most common culprit. Verify the wrap trigger switch has continuity per page 91. If mechanics check out, run a full wrap cycle with the PTO at 540 RPM and watch for hesitation at the drive chain.
Manual Section: Section 68 - TyingPickup or stuffer area plugs repeatedly, especially in heavy or wet crop conditions p. 115
Examine the pickup fingers and cam bearing for wear. Torque the cam bearing nut to 113 N·m (83 ft. lbs.) per page 116. Check the drive chain tension at the idler, targeting 5-13 mm (3/16-1/2") sag per page 120. Confirm the slip clutch setting: initial cap screw torque is 13 N·m (120 in. lbs.) and slip torque is 316 N·m (2800 in. lbs.) per page 118.
Manual Section: Section 60 - Product FeedingDrive roll bearings worn or seized, producing grinding noise during bale formation p. 139
Pull the drive roll assembly per Section 62. Inspect both bearing bores for spalling, pitting, or discoloration and replace as needed. Torque the M16 cap screws to 240 N·m (177 ft. lbs.) and M10 bearing cap screws to 56 N·m (41 ft. lbs.) per page 139. Spin the roll by hand to confirm smooth rotation before reassembly.
Manual Section: Section 62 - PressingApron belts track to one side, crowd a roll, or flip over during operation
Look for uneven crop feeding first, as side-loading is the most common cause of belt migration. Inspect all roll surfaces for debris or worn crowns. Adjust the roll position per the tracking procedure. The replacement belt length is 6920 mm (272.5"). For damaged belts, review the failure analysis before ordering to confirm the root cause.
Manual Section: Section 62 - PressingPTO shear bolt fails repeatedly or driveline bangs under normal operating conditions p. 44
Always replace with the correct grade shear bolt; a hardened substitute bypasses the designed shear point. The verified shear bolt setting is 1080 N·m (796 ft. lbs.) per page 44. Inspect the slide collar quick-disconnect and CV U-joints for binding per the overhaul procedure on page 45. If shearing continues with correct hardware, check the pickup slip clutch drag.
Manual Section: Section 31 - Implement DrivelineFrequently Asked Questions
How do I fix net wrap that fails to start or wraps intermittently on the New Holland BR7050?
Start by checking the brake/retention assembly (page 179). Manually rotate each roller in the wrap system to identify binding. A sticking brake roller is the most common cause of intermittent wrap starts; the repair procedure walks through disassembly, inspection, and reassembly of the retention mechanism.
What should I do when the BR7050 pickup or stuffer area plugs repeatedly?
Examine the pickup fingers and cam bearing for wear (page 115). Torque the cam bearing nut to 113 N⋅m (83 ft. lbs.) after any bearing replacement. Worn cam bearings allow finger timing to drift, causing the pickup to throw crop into the stuffer at the wrong angle — which plugs the machine even at moderate throughput.
What are the torque specs for the pickup bearings on a New Holland BR7050?
Torque the pickup cam bearing nut to 113 N⋅m (83 ft. lbs.) when installing a new bearing. This specification applies after any bearing replacement or cam disassembly (page 116).
What are the torque specs for the roller chain sprocket bolts on a New Holland BR7050?
Tighten the starter roll sprocket bolts to 52 N⋅m (38 ft. lbs.). This value applies to the specific fasteners labeled as starter roll sprocket bolts in Section 62 (page 133).

Document Quality
This document is a scanned PDF, meaning the text is embedded as images rather than being natively digital. While an OCR layer has been applied, allowing you to search the full text and copy content, the text itself is rasterized and appears slightly less crisp than a native digital document. Diagrams and illustrations are also raster images, but their labels are generally clear and readable. All pages are clean with no noticeable scan artifacts, stains, or skewed content, and there are a few blank pages serving as section breaks.
