Cylinder Block Ladder Stiffener - the ladder-frame reinforcement in the lower crankcase of the 2.4L Duratorq-TDCi HPCR 140PS diesel engine.

The stiffener bolts to the underside of the cylinder block and ties the main bearing saddles together into a single rigid frame, so that crankshaft main bearing alignment is held under combustion and torsional load. It also forms the machined mating face that the sump seals against, which makes the condition of its flange and sealing surface critical to a leak-free bottom end.

The stiffener is disturbed whenever the sump is removed or the crankshaft main bearings are accessed. Clean both sealing faces back to bare metal, renew the sealing arrangement, and follow the specified bolt tightening sequence and torque on refitting.

Frequently asked questions

What is the LR146345G block stiffener?
The LR146345G is the cylinder block ladder stiffener for the 2.4L Duratorq-TDCi HPCR 140PS diesel in the Defender (2007-2016). It bolts to the underside of the cylinder block and ties the main bearing saddles into a single rigid frame, holding crankshaft main bearing alignment under load.
Where does the block stiffener fit on the engine?
The block stiffener fits the lower crankcase of the 2.4L Puma Defender engine, bolted beneath the cylinder block. It also forms the machined mating face for the sump, so it's involved whenever the bottom end or oil pan is opened up on this engine.
Which Defender does this block stiffener fit?
The LR146345G fits the Defender (2007-2016) with the 2.4L Duratorq-TDCi HPCR 140PS diesel (the Td4 2.4), VIN (V)7A000001 to BA999999. It's specific to that engine, so it doesn't fit the later 2.2L Puma or earlier Td5. Check your engine and VIN before ordering.
