The ZD320-3 is a crawler bulldozer of about 37 tonnes, not a drilling rig; the same engine code is also quoted for the ZD320-6 and for Shantui in the SD32.
C360S10 and C280S10 are separate builds of the same 855 block, and a plain C360 or a C360S1 is quoted in the market as well.
269 kW at 2100 rpm is the engine figure, 257 kW at 2000 rpm is the figure printed in the machine brochure, and the bare engine option is listed at 1509 Nm.
The A in NTA855 denotes aftercooling, so headings that mix NT855 and NTA855 are not describing the same build.
Some entries carry NTA855, NT855, KT19, KTA19, K19, KT38 and K50 in one line, and one adds N855, which is not a series designation.
Assemblies run from about 6600 CNY to 156000 CNY per piece, with rebuilt units near 17000.
Cylinder head 4915442; injector 3054220; injector tube 3070486; PT pump 4951495; water pump 3022474; exhaust manifold 3072582; piston and liner kit; bearings; gasket set; turbocharger; oil pump; overhaul kit.
The ZD320-3 is a crawler bulldozer of about 37 tonnes, and its engine is the NTA855-C360, which several specification pages print as NTA855-C360S10. The S10 is a build suffix inside the rating code rather than a separate engine, and the same build is quoted for Shantui in the SD32 as well.
One figure belongs to the engine and the other to the machine. The engine page publishes 269 kW and 360 hp at 2100 rpm with 1464 Nm, while the brochure for this bulldozer quotes 257 kW at 2000 rpm. A bare engine sold for the same machine is listed at 1509 Nm at 1400 rpm, so the ratings cannot be used interchangeably.
The rating, with its fuelling and governor settings. Both are 14 litre 855 blocks, but the C280 build is the lower output version and the C360 is the one quoted for this bulldozer. Ordering on the series name alone leaves the build undecided.
No, the A denotes aftercooling, so the two are different builds.
4915442 is the head assembly and 4951495 the PT fuel pump.
