Product Overview
The 9142722 is a heavy-duty starter motor delivering 12V output at 2.7KW, with the page also listing a 3.5KW rating, and an 11-tooth drive gear, engineered for Ursus, Balkan and related Zetor, Balkancar, Valtra and Valmet tractor and forklift platforms. This unit, cross-numbered as 6918.5771 and in the Lucas LRS series, matches the original starting-system specification for these agricultural and material-handling machines.
Fitted with reduction-gear drive design, this brand-new engine starter is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The factory-correct rating ensures reliable cold and hot cranking of the tractor and forklift diesel engine.
Key physical specs: net weight 5.3 kg, gross weight 5.6 kg, overall dimensions 260 x 160 x 160 mm, supplied inside neutral kraft inner carton.
The Ursus, Zetor, Balkancar, Valtra and Valmet Tractor Platform and 12V Starting System
Ursus, Zetor, Balkancar, Valtra and Valmet tractors and forklifts run standard 12V starting systems with heavy-duty factory-spec starter motors. The starter motor numbering spans the 9142722 family, the Lucas 6918.5771 series, the Lucas LRS series and the 11.130.179/80350911 cross numbers, all referring to the same starting-system family.
It is critical to verify the drive-gear tooth count on your old starter: this unit uses an 11-tooth drive gear. Starters with a different tooth count or mounting pattern are not interchangeable with this unit. A starter with the wrong tooth count will not engage properly with the flywheel ring gear.
The 12V 2.7KW / 3.5KW dual rating matches the original starting-system specification. Confirm the mounting flange pattern, terminal positions and bolt spacing against your original starter before ordering. Always cross-check the OE numbers stamped on your old unit, including the 9142722 family, before placing an order.

Compatibility and Cross Reference
This starter motor fits Ursus, Balkan and related Zetor, Balkancar, Valtra, Valmet, Caravel, Desta and Dimex tractor and forklift platforms. Do not rely solely on the brand name for fitment validation; always compare the original part number, mounting holes, gear teeth and connector configuration before ordering.
| Brand | Application | Notes |
|---|---|---|
| Ursus | Tractor / agricultural | Verify 12V 2.7KW 11T |
| Zetor | Tractor / agricultural | Verify OE number |
| Balkancar | Forklift / material handling | Verify OE number |
| Valtra / Valmet | Tractor / agricultural | Verify OE number |
| Caravel / Desta / Dimex | Tractor / industrial | Verify OE number |
Multiple Lucas, OEM and aftermarket OE numbers appear across production batches and regional market specifications for this same starter motor family. If your original unit bears one of the listed cross-reference numbers, 9142722 serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the voltage and power label on your old starter: confirm it is rated for 12V at either 2.7KW or 3.5KW. Other ratings are not interchangeable.
2. Count the drive-gear teeth: this unit uses 11T (11-tooth). Starters with a different tooth count, including 8T or 9T units, are incompatible.
3. Confirm the platform is an Ursus, Zetor, Balkancar, Valtra or Valmet tractor or forklift. Other machines may use different starter assemblies.
4. Compare the mounting holes, flange pattern and connector configuration with your original starter, and match OE numbers including the 9142722 family.
5. Weight cross-check: genuine matching unit weighs approximately 5.3 kg net; significant weight difference indicates wrong assembly.

FAQ
Q: Which machines does this starter fit?
A: It fits Ursus, Balkan and related Zetor, Balkancar, Valtra, Valmet, Caravel, Desta and Dimex tractor and forklift platforms. Confirm your machine, engine model and OE number before ordering.
Q: The page shows 2.7KW and 3.5KW, which rating is correct?
A: The page lists a dual rating of 12V 2.7KW / 12V 3.5KW. Confirm the power rating marked on your old starter before ordering; the starter covers both ratings in this family.
Q: My old starter shows OE number 6918.5771 or 80350911, will 9142722 work?
A: Yes. These numbers belong to the same starter motor family for this tractor platform, differing only by production revision and market specification. It serves as a direct replacement.
Q: Can I fit this starter onto other machines?
A: No. Different engine families use different starter mounting patterns, drive-gear tooth counts and terminal layouts. Confirm your machine model before ordering.
Q: What is the correct operation after installation?
A: The engine should crank briskly and consistently on cold and hot starts. If the starter spins but the engine does not crank, check the drive-gear engagement and ring gear condition.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, incorrect wiring, water ingress, short circuit or physical damage.
In Practice
For technicians working on Ursus, Zetor, Balkancar, Valtra and Valmet machines: Before removing the existing starter motor, confirm the engine is off and the battery is disconnected at the negative terminal first, and park the machine on a flat surface with the parking brake engaged. Remove the battery cable from the B+ terminal of the solenoid, noting the correct orientation of each connection, and label or photograph the wiring before disconnecting.
Remove the mounting bolts supporting the starter motor and lower it from the flywheel housing, taking care not to damage the flywheel ring gear or wiring. Compare the new starter against the old unit: verify mounting flange, bolt spacing, the 11-tooth drive gear and connector configuration. Clean the mounting surface, position the new starter, and tighten mounting bolts in stages to factory torque (typically 35-45 N.m). Reconnect the solenoid wiring and battery cable, ensuring terminals are clean and tight.
After installation, reconnect the battery and carry out a cranking test: the starter should engage promptly with a clean, crisp sound and no grinding or whine. Confirm the engine starts consistently on repeated attempts. Inexperienced mechanics are recommended to entrust replacement work to a qualified equipment service shop.
