Used OEM Timing Components for Trucks, Lorries & HGVs

Used truck Timing Components

Timing Components are critical engine parts used to keep the crankshaft, camshaft, fuel pump drive and related rotating assemblies working in the correct relationship. On heavy commercial vehicle engines, the timing system is not just about starting and running; it affects combustion timing, fuel delivery, valve operation, engine smoothness and long-term reliability. A worn, damaged or incorrectly matched timing gear, front timing cover or intermediate gear can cause poor running, abnormal noise, oil leakage, gear train wear and, in severe cases, internal engine damage.

VRA Truckparts lists used OEM Timing Components removed from dismantled commercial vehicles, with stock changing depending on donor trucks and engines processed. Current examples in this category are mainly MAN applications, including MAN TGX, TGS and TGM parts for D20, D26, D2066 and D2676 engine families. Listings may include front timing covers, intermediate timing gears, crankshaft gears and camshaft or fuel pump drive gears with references such as 51015013056, 51.01501-3056, 51015010075, 51113066007, 51113066008, 51021150256, 51.02115-0256, 51021150293, 51045053065, 51.04505-3065, 51045055093, 51045053063, 51.04505-3063, 51113063010 and 51113065007. Always check the individual listing, as part numbers, cast markings and donor details are the key to choosing the correct used OEM part.

What you will find in the Timing Components category

This Timing Components category sits within Engines & Components for lorry, truck and HGV parts. It is intended for mechanical timing-related engine parts rather than general engine accessories. Availability is based on genuine used stock from vehicles being dismantled, so the exact range may vary. When available, this category can include:

• Front timing covers and front engine covers, such as MAN TGX/TGS covers with OEM references including 51015013056 and cast marking 51.01501-3056.
• Intermediate timing gears for MAN D2066 and D2676 engines, including gear assemblies listed with numbers such as 51045053063, 51045053065 and 51113063010.
• Crankshaft gears used within the engine gear train, including MAN references such as 51021150256 and related cross references where shown.
• Fuel pump drive gears or CR fuel pump drive-related gears, for example MAN TGX/TGS intermediate gear references such as 51113066007 and 51113066008.
• Camshaft drive gears and related engine gears for matching the correct timing drive layout on MAN heavy-duty engines.
• Used OEM gear train components supplied with listing photos, visible markings and part references where available.
• Related engine timing hardware that may appear depending on donor engine condition, dismantling requirements and current warehouse stock.

Truck brands & typical applications

The current Timing Components examples are strongly focused on MAN heavy commercial vehicles, especially MAN TGX, MAN TGS and MAN TGM engine applications. Product listings mention D20 and D26 engine families as well as D2066 and D2676 engines, and some items are identified for Euro 6 applications. Compatibility must not be assumed from model name alone, because MAN engines can vary by production year, emission standard, power output, gear train design and exact engine code.

• MAN TGX applications, including front timing covers, crankshaft gears and intermediate timing gears removed from donor vehicles.
• MAN TGS applications where the same or related D20, D26, D2066 or D2676 timing gear references are used.
• MAN TGM applications where specific intermediate gear assemblies match the engine family and OEM reference.
• Euro 6 MAN engines where listings clearly state the Euro standard or donor application.
• Other truck brands may appear in this Timing Components category as stock changes, but each listing should be checked individually by part number and physical comparison.

Why Timing Components matters

Correct Timing Components are essential for maintaining the relationship between the engine crankshaft, camshaft and driven accessories. In a heavy truck engine, the gear train has to operate under high load for long running hours. Even small differences in tooth form, hub depth, gear width, offset, cover shape or mounting pattern can make a part unsuitable. A used OEM timing gear that matches the original reference can be a practical option for workshops repairing an engine where the original component is damaged, missing, worn or contaminated during another repair.

Timing covers also have an important role beyond simply closing the front of the engine. They may help retain oil, protect rotating gears, provide mounting points and maintain the correct sealing surface around the front gear train. A cracked, distorted or incorrectly matched front timing cover can lead to oil leaks, misalignment concerns or poor sealing. For this reason, buyers should treat Timing Components as precision engine parts and compare details carefully before ordering.

Typical reasons to replace Timing Components

Timing Components are often replaced during engine repairs, rebuilds, accident repairs or when a fault is found during dismantling. Common reasons a workshop may need a replacement used OEM part include:

• Worn, chipped or damaged gear teeth caused by age, contamination, incorrect lubrication or previous internal failure.
• Cracked or broken timing cover sections, especially around bolt holes, sealing faces or mounting points.
• Oil leaks from damaged front timing covers, distorted faces or worn sealing areas.
• Incorrect previous replacement part fitted to the engine, causing alignment, clearance or timing issues.
• Damage during engine removal, strip-down, accident impact or handling in a repair environment.
• Missing gear train components during engine rebuilds or when an incomplete used engine is being prepared for service.
• Need to replace a specific OEM gear or cover rather than modify a non-matching aftermarket or pattern part.

How to choose the correct Timing Components

Timing Components must be matched accurately. A part may look similar in photos but differ in tooth count, casting design, gear width, hub position, bolt pattern, cover profile or associated engine application. Before ordering, check:

• The truck make, model and generation, such as MAN TGX, TGS or TGM where relevant.
• The engine family and engine code, including MAN D20, D26, D2066 or D2676 where shown on the listing.
• The Euro or emission standard, especially where a listing identifies Euro 6 applications.
• The OEM number and any alternative reference, for example 51015013056, 51113066007, 51021150256, 51045053065, 51045053063 or 51113063010.
• Cast markings and handwritten tag details, as these may confirm or cross-reference the part when the main number is unclear.
• Gear tooth count, gear diameter, gear thickness, hub depth and visible wear marks where relevant.
• Bolt holes, dowel positions, sealing faces, cover shape and mounting points for timing covers.
• Listing photos, donor vehicle notes and included parts, as some listings may include only the gear while others may show an assembly.

Before purchase, compare the old unit with the listing photos and reference numbers. If you are unsure, use how to find the right truck part or compatibility and VIN checks for guidance. Supplying the VIN, registration, engine code, old part number and clear photos of the part removed from the vehicle can help reduce the risk of ordering the wrong Timing Components.

Used OEM parts from dismantled trucks

VRA Truckparts supplies used genuine OEM commercial vehicle parts removed from donor trucks. Timing Components are identified during dismantling, photographed and listed with available OEM numbers, cast references and application notes where possible. Some parts may show normal used wear, oil staining, handling marks or surface marks consistent with previous service in an HGV engine. Any important visible details should be reviewed in the product photos and description.

Because Timing Components are precision engine parts, the listing information matters. Some parts are visually inspected before listing, and where a component was removed from a running donor vehicle or checked before dismantling, this may be stated in the individual product description. VRA Truckparts does not recommend guessing compatibility based only on the model badge. For more information about how used truck parts are removed and prepared, see our dismantling and quality process and trucks we dismantle.

Part numbers, casting marks and cross references

Many Timing Components carry more than one useful reference. A MAN timing gear may have an OEM number written in catalogue format, a cast number on the gear itself and a handwritten stock tag showing a cross reference. For example, listings may show numbers with and without punctuation, such as 51.04505-3063 and 51045053063, or 51.02115-0256 and 51021150256. These references should be compared carefully because a single digit error can lead to the wrong part being ordered.

Where a listing states that a supplied number was incorrect but the photo tag or cast marking confirms a different number, prioritise the clear listing details and photos. Workshops often search using the number taken from the original part, the vehicle build data or an electronic parts catalogue, so checking all visible references is the safest approach.

Related categories

Timing Components are part of the wider engine repair area, so buyers may also need related engine parts during a repair. If you are rebuilding, replacing or inspecting a MAN D20, D26, D2066 or D2676 engine, check the relevant Engines & Components sections on the site as stock allows. For help identifying a part that is not currently listed in Timing Components, use how to find the right truck part or send details for compatibility and VIN checks. Related items may appear depending on dismantled vehicles and current stock, so it is worth searching by OEM number as well as by vehicle model.

Delivery, payment & returns

When ordering used OEM Timing Components, review the product listing carefully, confirm the part reference and make sure the delivery address and VAT details are correct at checkout. Practical information is available in delivery and shipping, payment and VAT information, warranty and part condition and returns and refunds. If there is any doubt about fitment, it is better to check before ordering rather than after the engine is stripped and waiting for a replacement part.
