VW Transporter T5 T5.1 2010-2015 2.0 TDI Crankshaft Pulley 038105243M #85

Genuine used Volkswagen Transporter T5.1 2.0 TDI crankshaft pulley / vibration damper, part number 038105243M, suitable for selected 2010–2015 2.0 TDI applications.

This pulley is mounted to the crankshaft and drives the engine auxiliary/serpentine belt system. Its vibration-damping construction also helps absorb torsional vibration produced by the crankshaft, reducing vibration and shock loads transmitted into the auxiliary belt drive.

Technical Information

The crankshaft pulley is attached to the front end of the engine crankshaft.

As the engine rotates, the pulley transfers crankshaft rotation to the auxiliary drive belt.

Depending on vehicle specification, the auxiliary belt system can drive components including:

* Alternator

* Air-conditioning compressor

* Power-assisted steering-related equipment where applicable

* Other auxiliary components according to engine configuration

The pulley therefore needs to run accurately and concentrically at all engine speeds.

Vibration Damper Information

Volkswagen’s parts catalogue describes 038105243M as a vibration damper.

This is important because it is more than a simple solid metal belt pulley.

The damper is designed to help absorb and isolate torsional vibration generated by the crankshaft during engine operation.

This helps protect:

* Auxiliary drive belt

* Belt tensioner

* Idler pulleys

* Alternator pulley

* Auxiliary bearings

* Other belt-driven components

As the pulley ages, deterioration of its damping section can allow excessive vibration into the auxiliary drive system.

Common Symptoms of a Worn Crankshaft Pulley

Typical symptoms can include:

* Excessive vibration from the auxiliary belt

* Pulley visibly wobbling

* Belt running incorrectly

* Squeaking or chirping noises

* Knocking or rattling from the pulley area

* Excessive auxiliary-belt movement

* Belt tensioner jumping excessively

* Cracked or deteriorated damper section

* Pulley running out of alignment

* Repeated auxiliary-belt problems

A severely deteriorated pulley can eventually cause the auxiliary belt to come off or become damaged.

Visual Inspection

The crankshaft pulley should be inspected for:

* Cracks

* Distortion

* Excessive corrosion

* Damaged belt grooves

* Signs of separation

* Deterioration of the damping material

* Abnormal movement between pulley sections

* Impact damage

* Excessive wear

* Wobble or run-out

Any obvious separation or distortion is a reason for replacement.

Important Diagnostic Information

Abnormal auxiliary-belt vibration does not automatically mean the crankshaft pulley is faulty.

Also inspect:

* Auxiliary drive belt

* Automatic belt tensioner

* Idler pulleys

* Alternator pulley/freewheel

* Alternator bearings

* Air-conditioning compressor pulley

* Associated accessory bearings

* Engine mounts

A seized alternator freewheel pulley or worn tensioner can produce substantial belt vibration and may be incorrectly diagnosed as a crankshaft pulley problem.

Alternator Freewheel Pulley

The alternator pulley is particularly important on modern diesel engines.

Its freewheel mechanism helps isolate rotational fluctuations within the auxiliary drive system.

If it seizes, symptoms can include:

* Belt tensioner jumping

* Excessive belt vibration

* Noise at idle

* Noise when switching the engine off

* Premature auxiliary-belt wear

The alternator freewheel should therefore be checked when diagnosing crankshaft pulley or auxiliary-drive vibration.

Auxiliary Belt Inspection

If the crankshaft pulley is being replaced, inspect the auxiliary belt for:

* Cracking

* Fraying

* Glazing

* Contamination

* Missing rib sections

* Uneven wear

A damaged or contaminated belt should not normally be reused.

Installation

Before installation:

* Compare 038105243M with the original pulley

* Inspect the crankshaft mounting surface

* Check pulley dimensions

* Compare belt-groove configuration

* Inspect mounting holes

* Check the auxiliary belt

* Check the belt tensioner

* Check idler pulleys

* Check the alternator freewheel pulley

During installation, the correct VW workshop procedure and specified tightening sequence/torque should be followed.

Incorrect tightening can potentially damage the pulley, mounting hardware or crankshaft connection.

Important Fastener Information

Crankshaft pulley mounting bolts may be specified by Volkswagen as replacement/stretch-type fasteners depending on the engine and exact installation.

The correct workshop information should therefore be consulted before installation.

Do not automatically reuse mounting bolts without checking the manufacturer’s procedure.

After Installation

After fitting:

* Check pulley alignment

* Check auxiliary-belt routing

* Confirm the belt is seated correctly in all grooves

* Start the engine and observe pulley operation

* Check for abnormal wobble

* Check belt tensioner movement

* Listen for abnormal noises

The pulley should rotate smoothly without excessive lateral movement.

Programming / Coding

No programming or coding is required.

The crankshaft pulley / vibration damper is a purely mechanical engine component.

Important Compatibility Note

Please compare before ordering:

* OE number – 038105243M

* Engine code

* Vehicle production date

* Pulley diameter

* Pulley width

* Belt-groove configuration

* Mounting-hole arrangement

* Centre bore

* Original pulley design

Aftermarket catalogue data for 038105243M commonly lists pulley diameters of approximately 138–143 mm, depending on manufacturer and measurement method, with a 6PK-type auxiliary belt configuration.

Because different pulley versions exist, the OE number and physical configuration should take priority over dimensions quoted from aftermarket catalogues.

Do not purchase solely because your vehicle is a Transporter T5.1 2.0 TDI.

Matching 038105243M directly with the original component is strongly recommended.

Condition

Genuine Volkswagen used crankshaft pulley / vibration damper.

As a used engine component, normal signs of previous use may include:

* Surface marks

* Dirt

* Belt-contact marks

* Light surface corrosion

* Cosmetic wear

* General installation/removal marks

Please inspect all listing photographs carefully, particularly the:

* Belt grooves

* Damper section

* Centre bore

* Mounting holes

* Outer pulley surface

* Overall alignment/condition

Mounting bolts are included only if clearly shown in the listing photographs.

Any identifying colour/security markings applied to the part must remain intact in the event of a return.

Ideal genuine replacement for a worn, damaged, cracked or excessively vibrating Volkswagen Transporter T5.1 2.0 TDI crankshaft pulley / vibration damper, provided 038105243M matches the original component.
