Overview
The Cummins 6CTAA8.3 is a 8.3 L 6-cylinder Cummins diesel engine supplied in 4 factory ratings from 195 hp (143 kW) to 260 hp (194 kW). Every rating listed on this page is a complete engine for construction duty, not a generator set, and each unit ships with its serial number recorded against the specification sheet that applies to it.
Ratings in this family differ in rated speed, peak torque and emissions tier rather than in displacement or cylinder count, so the choice between them is a duty-matching question. The specifications panel and the per-rating entries on this page are generated from the same source data, so a rating quoted here can be matched directly against a delivery document.
Specifications
The specifications panel lists the family-level values that are common to every 6CTAA8.3 rating, including the 8.3 L displacement and the inline 6-cylinder layout. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: 6CTAA8.3 Ratings
Each entry in this section is one rating of the Cummins 6CTAA8.3. The rated power is the output at the stated speed; the peak torque figure is the value the rating develops at the lower speed shown, which is what normally decides whether a rating suits a given machine. Each rating carries a stable anchor, so a single rating can be linked or quoted directly.
6CTAA8.3-C195
6CTAA8.3-C195 — rated 143 kW (195 hp) at 1900 rpm; peak torque 940 N·m at 1500 rpm; emissions Euro II.
6CTAA8.3-C215
6CTAA8.3-C215 — rated 160 kW (215 hp) at 2200 rpm; peak torque 980 N·m at 1500 rpm; emissions Euro II.
6CTAA8.3-C240
6CTAA8.3-C240 — rated 179 kW (240 hp) at 2200 rpm; peak torque 1040 N·m at 1400 rpm; emissions Euro II.
6CTAA8.3-C260
6CTAA8.3-C260 — rated 194 kW (260 hp) at 2200 rpm; peak torque 1100 N·m at 1400 rpm; emissions Euro II.
Applications
6CTAA8.3 engines in this family are normally specified for construction work.
Construction duty: the ratings with the higher peak torque are the ones normally quoted for loaders, dozers and haul trucks, where the engine has to hold torque under a sudden increase in load at low ground speed.
Duty cycle: the lower ratings in the same family are used where the duty cycle is closer to continuous and the installed package limits the cooling or the coupling that can be fitted.
Emissions: the ratings listed here carry Euro II. Where a market imposes a different standard, confirm the tier before ordering, because the same model number can be built to more than one tier.
Verification, Documentation and Ordering
Each engine is offered with nameplate verification + load-test record per serial number. That means the model and rating printed on the engine nameplate can be checked against the record issued for that serial number before shipment, which is the point most buyers of re-rated or re-exported engines want covered.
To receive a quotation, send the exact rating from the matrix above (for example 6CTAA8.3-C260), the machine or application it will drive, the quantity, and the destination port. If the rating you need is not listed, send the model and the required output and we will confirm whether it belongs to this family or to a neighbouring one.
Buyer tip: Send your 6CTAA8.3 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the power range of the 6CTAA8.3?
The 4 ratings listed on this page run from 195 hp (143 kW) to 260 hp (194 kW), at governed speeds between 1900 and 2200 rpm.
What displacement and cylinder count does the 6CTAA8.3 use?
Every rating in this family shares the same 8.3 L displacement and inline 6-cylinder, 4-cycle configuration. Ratings differ in output, rated speed and emissions tier rather than in the base engine.
What is the difference between 6CTAA8.3-C240 and 6CTAA8.3-C260?
6CTAA8.3-C240 is rated 179 kW (240 hp) at 2200 rpm with peak torque of 1040 N·m, while 6CTAA8.3-C260 is rated 194 kW (260 hp) at 2200 rpm with 1100 N·m. They use the same base engine; the higher rating is the one to specify when the driven load needs the extra torque at the lower speed.
Which emissions tiers are available for the 6CTAA8.3?
The ratings on this page are listed as Euro II. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a 6CTAA8.3 rating ordered?
Send the exact rating shown in the model selection table, the application it will drive, the quantity and the destination port. The engine is then quoted against that rating and confirmed against its nameplate and load-test record.
