All 142 pages of this International 435 service manual PDF are built around one job: keeping your 435 or 445 Pickup Baler running, from the PTO shaft and flywheel through the gearbox, packer crank, plunger assembly, and into the knotter and Lok Twist twisting mechanism. Inside: a full section of high-quality exploded views covering every major subassembly, system diagrams for the tying and twisting mechanisms, and detailed torque data with clearance specs for gearbox bearings, packer shafts, and wheel hubs. Set gearbox pinion shaft preload to 288-403 kgm (25-35 lbft) and hold disc drive shaft end float to 0.13-0.38 mm; those factory numbers are in here with full context. Your knotter's dropping twine and hay's still in the field. Bookmarked and searchable; open it on your phone, jump straight to the knotters section, and get wrenching.

International 435, 445, 435 Pickup Balers, 445 Pickup Balers Common Problems This Manual Covers
International 435 twine knotter fails to tie, complete bales dropping unbound from the bale chamber p. 107
Follow the disassembly sequence on page 107 to access the knotter disk; inspect for cracked teeth and packed twine debris. Measure disc drive shaft end float; spec is 0.13 to 0.38 mm (0.005 to 0.
Frequently Asked Questions
What are the replacement specifications for Knotter disk?
When replacing or servicing the knotter disk, ensure the disc drive shaft end float is between 0.13 to 0.38 mm (0.005 to 0.015 in). Additionally, the disc pinion delay surface clearance should be maintained at 0.025 to 0.38 mm (0.001 to 0.015 in) for proper operation.
What are the replacement specifications for Twister blade?
For the twister blade, the critical replacement specification is the knife to front disc clearance. This clearance should be set to 0.03 to 0.38 mm (0.001 to 0.015 in) to ensure correct operation of the tying and twisting mechanism.
How do you fix international 435 twine knotter fails to tie, complete bales dropping unbound from the bale chamber?
Follow the disassembly sequence on page 107 to access the knotter disk; inspect for cracked teeth and packed twine debris. Measure disc drive shaft end float; spec is 0.13 to 0.38 mm (0.005 to 0.015 in). Set twine tension to 0.45 to 0.91 kg (1 to 2 lb), confirmed on page 14, before resuming baling.
How do you fix packer fingers not pushing hay into chamber, bales come out loose and underweight?
Inspect all packer finger linkage pins at page 45 for shear, wear, or missing cotter pins. Check each packer spring for fatigue fractures or set. Measure packer drive shaft backlash; it must fall within 0.25 to 1.8 mm (0.010 to 0.070 in) per page 12. Replace worn pins and springs together; loose linkage compounds rapidly under sustained field load.
