Product Overview
The 29MT 5340058 is a brand-new starter motor delivering 24V output at 4.5KW with a 10-tooth drive gear, engineered for Delco Remy 29MT series applications on CUMMINS 6BT 5.9L, QSB6.7 and QSB7 engines. This unit, cross-numbered as 8201043 and STD2815ML, matches the original starting-system specification for the CUMMINS 6BT/QSB platform.
This starter motor is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The factory-correct 24V 4.5KW specification ensures reliable cranking performance for CUMMINS and Delco Remy applications.
Key physical specs: net weight 8.05 kg, gross weight 8.6 kg, overall dimensions 440 x 240 x 190 mm, supplied inside neutral kraft inner carton.
The CUMMINS 6BT/QSB Starting Platform
CUMMINS 6BT 5.9L, QSB6.7 and QSB7 engines use a 24V starting system with 10T starter motors in the Delco Remy 29MT series. The starter numbering spans the main numbers (29MT, 5340058), the 820 series (8201043, 8200475, 8200297), and the number STD2815ML from the original title, all referring to the same starting-system family for the CUMMINS 6BT/QSB platform.
It is critical to verify the voltage, power rating and tooth count on your old starter: this unit is rated at 24V 4.5KW with a 10T drive gear. Starters with a different voltage, power rating, tooth count or mounting pattern are not interchangeable with this unit. The 10T drive gear is a key identification point for this unit, so count the teeth on your old starter pinion carefully.
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 29MT and 5340058 family, before placing an order.

Compatibility and Cross Reference
According to the original product page, this starter motor fits CUMMINS QSB6.7 and QSB7 engines, and the original title adds the 6BT 5.9L application. The original page does not publish a detailed fitment table, so do not rely on the engine name alone for fitment validation; always compare the original part number, mounting holes, tooth count and connector configuration before ordering.
| Brand | Application | Notes |
|---|---|---|
| CUMMINS | 6BT 5.9L engine | Verify 24V 4.5KW 10T |
| CUMMINS | QSB6.7 engine | Verify 24V 4.5KW 10T |
| CUMMINS | QSB7 engine | Verify 24V 4.5KW 10T |
| Delco Remy | 29MT series | Verify 24V 4.5KW 10T |
Multiple OEM and cross numbers appear across production batches and regional market specifications for this same starter family. If your original unit bears one of the listed cross-reference numbers, 29MT 5340058 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 rating on your old starter: confirm it is a 24V 4.5KW unit for the CUMMINS application. Other ratings are not interchangeable.
2. Check the tooth count on your old starter: confirm it is a 10T drive gear. Starters with a different tooth count are not interchangeable.
3. Confirm the application is a CUMMINS 6BT 5.9L, QSB6.7 or QSB7 engine, or a Delco Remy 29MT series application. Other engines 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 29MT and 5340058 family.
5. Weight cross-check: genuine matching unit weighs approximately 8.05 kg net; significant weight difference indicates wrong assembly.

FAQ
Q: Which engines does this starter motor fit?
A: It fits CUMMINS 6BT 5.9L, QSB6.7 and QSB7 engines in the Delco Remy 29MT series. Confirm your exact engine model and OE number before ordering, and check that your old starter is a 24V 4.5KW 10T unit.
Q: The original Attributes page lists "12V 65 A" as the product number, what does that mean?
A: That is an alternator-style specification (12V 65A) mistakenly entered on this starter page, and it does not describe this 24V 4.5KW 10T starter. It is removed from the Product number field in this article; the actual product number is 5340058.
Q: Why was 6BT5.9 moved out of the title?
A: 6BT5.9 is the CUMMINS engine code (6BT 5.9 litre) from the original title, moved to the applicable-models line in this article as an engine identification rather than a part number.
Q: Why was STD2815ML added to the part-number area?
A: STD2815ML appears in the original title but not in the part-number area; it is added to the part-number area in this article so that all numbers printed on the page are listed.
Q: My old starter shows number 8201043 or 8200475, will 5340058 work?
A: Yes. These numbers belong to the same 29MT starter family for the CUMMINS 6BT/QSB platform, differing only by production revision and market specification. It serves as a direct replacement.
Q: My old starter has 9 or 11 teeth, will this 10T unit fit?
A: No. The tooth count must match: this unit has a 10T drive gear, and a starter with a different tooth count is not interchangeable. Confirm the tooth count of your old starter before ordering.
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
The original product page does not publish a specific installation method or torque data for this starter. The following section therefore uses the general 24V heavy-duty starter installation standard, with reference to the common installation practice for CUMMINS 6BT/QSB starters and after-sales maintenance experience from the auto repair industry; before installation, compare the specific torque values with the corresponding CUMMINS service manual.
Disconnect the negative battery cable first to prevent short circuit and electric shock during installation. Remove the starter mounting bolts, disconnect the B+ main cable and the S control wire from the solenoid terminals, and mark them for reconnection. Take out the old starter smoothly, and inspect the flywheel ring gear for chipped or worn teeth; replace the ring gear if damaged. Clean the flywheel housing mounting surface and the starter flange, free of oil stains, rust and burrs.
Align the new starter with the flywheel housing spigot, insert the mounting bolts and hand-tighten, then tighten in a diagonal sequence in 2-3 steps with a torque wrench; for 24V heavy-duty starters, a typical reference torque for the main mounting bolts is 55-65 N.m, to be fine-tuned with reference to the corresponding CUMMINS model manual. Connect the S control wire to the solenoid S terminal, then connect the B+ main cable to the battery positive terminal, tightening the nut securely. Ensure the starter housing is grounded through the mounting bracket, free of rust and oil stains. Secure the wire harnesses to avoid contact with hot exhaust components and moving parts.
After installation, reconnect the negative battery cable and check the wiring connections. Start the engine and check that the starter engages smoothly and the pinion returns fully after starting. Each single start-up shall not exceed 5 seconds, with an interval of at least 10-15 seconds between consecutive start-ups to avoid overheating. If the starter fails to crank, check the battery voltage (at least 24V under load), the main cable connections and the solenoid operation before further testing.
