  • Application: John Deere PowerTech 4045T 4.5L 4-cylinder turbocharged diesel complete block assembly (long block)
  • Includes: Cylinder block with crankshaft, connecting rods, pistons and liners, camshaft and balancer shafts; cylinder head with valves, springs and rocker arm assembly; front plate and gear train; oil pump; full gasket kit with front and rear seals

  • Core Charge: $1,150 refundable core charge applies
  • Engine Code Notes: This assembly was built by John Deere Reman to replace the 4045TT013 engine in a 450G crawler dozer. The machines listed above share the 4045T PowerTech block family, but engine option codes and accessory configurations vary by model and build date. Call (800) 909-7060 with your engine option code to confirm before ordering.
  • LTL Truck Freight: Due to weight, this item ships via LTL truck freight. Shipping is calculated at checkout

Common Use Case or Symptoms: Use when your 4045T has a cracked block, spun main or rod bearing, scored liners, or low compression that a head job will not fix — a complete block assembly gets the machine back to work faster than a piece-by-piece overhaul.
