Model: WP13
Part Number: 612700010010
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 liner is the cylinder wall. It guides the piston, carries the rings, conducts combustion heat into the coolant and forms half of the sealing surface for the head gasket. On the Weichai WP13, part 612700010010 is the wet liner used across the 13-litre range, from 480 to 580 horsepower road engines to the industrial versions fitted in mining equipment and generator sets.
Because the WP13 is a high-load engine, liner condition usually decides the overhaul schedule. At four to six hundred thousand kilometres the bore may show a top ring ridge, glazing or vertical scoring, and at that point no ring set will restore compression. Replacing the liners with correctly honed parts is what makes a rebuild worth doing.
The liner fits WP13 road and industrial engines. Typical installations are HOWO and Shacman heavy tractors, 8x4 mining dump trucks, large loaders and 300 to 500 kVA generator sets. WP13 liners are not interchangeable with WP12 or WD618 parts; the bore and flange dimensions differ, so always confirm the engine plate and the old liner number.
A liner performs only if its final honing is correct. Ours are centrifugally cast in high-phosphorus iron, machined and plateau honed. Checks before packing:
Each liner is supplied with its O-ring set. Using the correct compound matters: the wrong O-ring swells in hot coolant and starts leaking within weeks.
If there is a visible ridge at the top of ring travel, the liner must be replaced, not honed. Honing an oval bore only delays the problem by a few thousand kilometres.
After assembly, fill coolant slowly, run to temperature and recheck the head bolt torque and coolant level after the first cool-down.
WP13 liners are often bought as a kit with pistons and rings. A matched kit avoids clearance problems caused by mixing brands. If you already have pistons, give us the piston part number and we will supply the matching liner and ring pack.
For fleets working in dusty conditions, inspect the air filter system at the same time. Dust ingress wears a new liner set faster than any other single cause.
Keep coolant chemistry in range to prevent cavitation pitting, change oil at the severe-duty interval and never run with a damaged air filter or a leaking intake hose. Cold starts in sub-zero weather accelerate wear, so use the correct oil viscosity and warm the engine before loading it.
Liner, piston and ring form one system. A liner honed for one ring type may not suit another, and mixing brands is the most common cause of oil consumption immediately after an overhaul. If you are rebuilding a WP13 with existing pistons, give us the piston part number and the ring pack specification so we can confirm the liner finish matches.
For a complete set, order the liner, piston and ring kit together. The parts arrive matched, which removes the guesswork and shortens assembly time. Workshops that rebuild several WP13 engines a year usually keep one complete set on the shelf alongside a gasket kit and a set of head bolts.
Yes, the correct O-ring set for the block bore is supplied with every liner.
It is possible, but on a high-mileage WP13 we recommend the full set so compression stays balanced across cylinders.
No. It arrives plateau honed, ready for ring seating.
Cavitation from incorrect coolant or air in the system. Use the specified coolant and keep the circuit free of air.
Browse the Weichai cylinder liner category, and pair these liners with the WP13 cylinder block 612700010001 or the WP13 cylinder head 612700040030.
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.
