Volvo L150E / L180E Wheel Loader Parts - Radiator, Control Valve and Bearing Wear List for Egypt
Why Egyptian quarry and port duty attacks the cooling pack first
Three conditions define loader work in Egypt: five months of 40 degree plus ambient, limestone and clinker dust fine enough to blind a radiator in two shifts, and continuous high load cycles with almost no idle time. The cooling pack sits in front of everything else, so when it fouls, engine coolant, transmission oil and hydraulic oil all run hot at the same time.
The real failure chain is: cooling pack fouling → oil and coolant temperature rise → thinner oil film in the pump and valve spools → spool sticking and slower boom response → operator works the machine harder → more heat and faster seal ageing → bearing and steering play appear. The most expensive cost on an Egyptian site is not the part. It is a loader out of the loading circuit while trucks queue at the hopper.
| Area | Field symptom | First check (free) | Usual fix |
|---|---|---|---|
| Radiator | Coolant temperature rise | Inspect core from the back with a light | Clean or replace |
| Control valve | Sticky boom, slow tilt | Compare spool travel and oil temperature | Clean or replace valve |
| Bearing | Noise, play, heat at the housing | Check radial play and temperature | Replace bearing |
| Steering gear | Steering play, wander on road | Measure free play at the wheel | Replace steering gear |
| Seal kit | External leaks, wet housings | Clean and watch where oil returns | Replace seals |
Radiator 15009622: clean first, replace second
15009622 radiator (VOE15009622) covers the L150E, L180E and L220E platforms. In Egyptian quarry dust it is normal to find the core half blocked while the machine still holds temperature at idle - the problem only appears under load.
Work the diagnosis in this order: inspect the core from the back with a light - if you cannot see light through the fins, it needs cleaning regardless of what the gauge says; compare inlet and outlet temperature - a small delta means internal blockage; verify cap pressure and fan drive before blaming the core. Cleaning with low pressure water and a fin comb recovers most units. Replace only when fins are corroded away or the tank seam leaks.
Set the cooling pack clean-out interval to every 250 hours in the dusty season. This single habit is the cheapest way to extend hydraulic and transmission life in Egypt.
Control valve 11716764: sticking is thermal, not wear
11716764 control valve (VOE11716764) serves the L150E, L150F and L180E platforms. When the boom feels sticky only after two hours of work, the cause is almost always oil temperature and varnish on the spool - not a worn valve body.
Confirm it in three steps: reproduce the fault when the oil is hot, not cold; measure hydraulic oil temperature at the tank; check return filter and suction strainer. If the fault disappears after an oil and filter change and a cooler clean-out, the valve is fine. Replace the valve only when spool bore scoring is visible or the fault persists at normal temperature.
Bearing 11703968 and steering gear 15135165
11703968 bearing (VOE11703968) fits L150E, L150F, L150G, L180E, L220D and L220E platforms, and 15135165 steering gear covers L180E, L220G and L250G machines. These two decide whether the loader tracks straight on the haul road and whether the driveline stays quiet.
Judge the bearing by radial play and housing temperature after a shift, not by noise alone - a dry bearing whines only in the last stage. Judge the steering gear by free play measured at the rim: more than specification, or wander that needs constant correction on a straight road, means the gear is due.
Replace the bearing before it spins in the housing. Once the bore is damaged, the job turns from a bearing swap into a housing repair or a new assembly.
Seal kit 11709645: oil on the ground is a schedule risk
11709645 seal kit (VOE11709645) covers L150 series loaders and A25D / A25E / A30D haulers. On Egyptian sites, hard seals are usually the first sign of overheating that nobody logged.
Diagnose by cleaning the housing and watching where oil reappears after one shift. A leak that returns at the same point is a shaft seal; oil spread over the whole housing is a breather or over-temperature problem. Fix the cause before fitting new seals, otherwise the new kit fails within a season.
Lead time, documents and packing to Egypt
Stock items ship the same day. Express delivery to Cairo, Alexandria, Port Said and Suez normally takes 5 to 9 working days. Heavy units such as radiators, steering gears and hydraulic assemblies move by sea freight consolidation, with sailing confirmed to Alexandria or Damietta before booking.
Hydraulic and cooling units are shipped with ports sealed, machined faces rust protected, and photographed before packing. Heavy items go on heat-treated-free pallets or in plywood crates. Before dispatch we send the packing list, actual product photos and a loading video. To quote, send three things only: a photo of the machine serial number, a photo of the old part nameplate, and a note on where it is fitted.
Frequently asked questions about L150E / L180E parts
Are the L150E and L180E radiators the same?
Not by model number alone. 15009622 covers L150E, L180E and L220E, but L150F, L180F and L220G use different references. Send the machine serial number and a photo of the old radiator nameplate and we confirm the correct part before shipping.
The boom gets sticky only after two hours - is the valve worn?
Usually not. Sticking that appears only at high oil temperature is varnish or a fouled cooler, not spool wear. Clean the cooling pack, change oil and filters, and re-test. Replace the valve only when the fault persists at normal temperature or bore scoring is visible.
How much play in the steering is acceptable?
Measure free play at the steering rim against the workshop specification. Any constant correction needed to hold a straight line on a haul road means the steering gear or linkage is due. Play also loads the centre bearing, so check both together.
Can I replace the seals without fixing the overheating?
No. Hard seals are a symptom of over-temperature. If you fit a new kit into a machine that still runs hot, the new seals harden within one season and the leak returns. Clean the cooling pack and verify oil temperature first.
