Model: WP13
Part Number: 612700010001
Brands: Weichai Power
Engine Model: WP13, WP13.480, WP13.500, WP13.550, WP13.580
Engine Type: Diesel
Scope of application: heavy haulage trucks, mining dump trucks, construction machinery, generator sets
The cylinder block is the structural backbone of a diesel engine. It carries the crankshaft in its main bearing saddles, holds the liners in their bores, provides the deck that the cylinder head bolts onto and contains the oil and coolant galleries. On the Weichai WP13, part 612700010001 is the bare block casting used across the 13-litre heavy-duty range, the engine that powers long-haul tractor units, 8x4 mining dump trucks and large generator sets.
When a block is cracked, badly worn at the main bearing saddles or has lost its deck flatness, no amount of new parts will bring the engine back. Replacing the block with a correctly machined casting restores the foundation that every other component depends on: crank alignment, liner protrusion, head sealing and oil pressure.
The 612700010001 block is specified for the WP13 series, including the 480, 500, 550 and 580 horsepower ratings used in Chinese heavy trucks and export markets. Typical installations are:
Because the block is the base for every variant, always confirm the engine plate and the old block casting number before ordering. There are early and late WP13 blocks with differences in the front cover bolt pattern and the oil cooler mounting face.
A block is only usable if its critical surfaces are true. Our blocks are checked and re-machined where necessary before shipping:
Blocks are shipped cleaned, oiled on machined surfaces and protected with a wooden or heavy carton base. Tell us at the time of order if you need the block with liners and cam bearings pre-fitted, so we can prepare it accordingly.
Most engine builders replace a block rather than repair it when they see:
A pressure test and a line bore check are the two measurements that decide the question. If either fails, replacement is usually cheaper than a repair.
Always replace the gallery plugs that were removed during cleaning, and use the correct thread sealant. A missing plug means zero oil pressure at start-up.
Three details decide whether a block will fit: the engine model, the casting number on the side of the block and the front cover bolt pattern. A WP13 block from an early production run may not accept a later gear train cover. Send us a photo of the old block casting number and the engine plate and we will confirm the match before shipping.
For workshops rebuilding WP13 engines regularly, buying the block together with liners, main bearings and the gasket kit saves both freight and assembly time.
Blocks rarely fail on their own; they fail because coolant, oil or alignment was neglected. Keep the coolant mixture correct to prevent liner pitting, change oil at the severe-duty interval, and never run the engine with a failed vibration damper because crank whip loads the main saddles. Check engine mounts at every major service: a collapsed mount lets the block flex and eventually cracks the bell housing area.
By default it is supplied bare. We can fit liners, cam bearings and gallery plugs to your specification on request.
In most cases no. Welding a main saddle distorts the bore alignment and fails again under load. Replace the block.
No. They are different castings with different bore spacing and deck height. Do not interchange them.
Deck flatness, main bore alignment, liner bore condition and the pressure test report. We supply these measurements on request.
Browse the Weichai cylinder block category, and complete the build with a WD615 and WP10 cylinder head 61560040040 or the WD615 full gasket kit 612600040355.
We offer OEM quality and excellent after-sales service as a complementary option. Engine brands supported include Weichai, Baudouin, Yuchai, Caterpillar, FAW Xichai, Sinotruk, Cummins and other engine parts. Specifically engine overhaul kits, pistons, cylinder liners, crankshafts, camshafts, fuel pumps, water pumps, lube pumps, injectors, and other performance parts.
If you are not sure about the part number that you need, please provide all the information you have, such as the equipment nameplate, engine nameplate or engine number, or real photos.
