This 6597N equivalent 28MT 24V starter motor is a practical, field-friendly replacement for TX-series service demand. It combines 4kW cranking with a 10-tooth pinion that matches the correct gear interface. For distributors, it’s a strong stocking SKU because fitment can be controlled by 10T + 40mm OD + 89mm engagement + terminal layout.

The 6597N starter motor is commonly matched by 24V 4kW, 10-tooth pinion, 40 mm pinion OD, and 89 mm engagement. These details prevent mix-ups with other 10T 28MT starters that have different OD or engagement.
No. 6597N is 10T, while 6591 is 12T. Tooth count mismatch can cause grinding or failure to engage, even though both are 28MT 24V.
Most often: wrong tooth count, wrong pinion OD (32 vs 40 mm), wrong engagement depth, or ring gear wear. For 6597N replacements, confirm 10T + 40 mm OD + 89 mm engagement.
Because 10T alone is not enough. Another 10T starter with 32 mm OD may have different meshing behavior. OD is a strong identifier for correct 6597N drive geometry.
It indicates pinion travel. Incorrect engagement can lead to partial engagement and noisy starts. Matching engagement helps prevent repeat service calls in agricultural equipment.
Common causes include battery voltage drop, corroded terminals, weak grounds, or relay/ignition signal issues—especially on farm equipment with vibration and dusty wiring.
After shutdown, heat increases resistance in weak cables and grounds. Many "starter failures" after hot soak are caused by wiring issues, not the starter motor itself.
Moisture accelerates corrosion at ground points. Stable grounding and protected terminals reduce intermittent no-crank complaints for 24V systems.
If terminal layout differs, the start signal may not reach the solenoid properly or auxiliary functions may be lost. Confirm the 4-terminal layout before purchase.
Send the number 6597N (or cross references), plus photos of the 10T pinion, solenoid terminals, and mounting face. Add 40 mm OD and 89 mm engagement if measurable.
