Looking up a 4JJ1XYBB-01 part number shouldn't take longer than the repair itself. This 80-page parts catalog (OEM #YOOF2161) breaks down every assembly in the Isuzu P-TCR50EDC diesel engine with exploded views paired directly to OEM part numbers. Twenty pages of engine diagrams cover gasket kits (head gaskets in 1.05mm, 1.10mm, and 1.15mm grades), cylinder block, camshaft, and valve assemblies. Separate sections detail the fuel injection system, turbocharger, cooling circuit, and electrical controls. Each item number links to the facing parts list so you order exactly what fits your serial number range. Need the 24V glow plug or the 32mm sealing cup from the cylinder head? Find them on page 15, confirm the effective machine number, and call it in. Bookmarked for quick jumping between sections; keyword search works across the entire PDF.

Isuzu P-TCR50EDC, 4JJ1XYBB-01 Common Problems This Manual Covers
Isuzu 4JJ1XYBB-01 turbocharger gasket kit part numbers not clear in catalog listing p. 48
Open the turbocharger system exploded view on page 48 for the full gasket and seal breakdown. Match each item number against the parts list on the facing page. For the full engine gasket kit, review pages 8 and 9, where head gaskets appear in three thickness grades (1.05mm, 1.10mm, and 1.15mm). Confirm the correct effective machine number range with your serial number before ordering.
Manual Section: Turbocharger SystemCan't identify correct fuel injector part numbers or find updated superseded components p. 50
Locate the fuel injection system exploded views starting on page 50, which span two pages of diagrams and parts lists. Look for the 'I' mark next to any part number; per the interchangeability guide, this flags a design change. Verify symbols (N, Q, R, S, W, Z, F, K) to determine whether old and new injector components cross with your serial number range.
Manual Section: Fuel Injection SystemNeed correct cylinder head sealing cup and glow plug specs for parts ordering p. 15
Turn to the cylinder head parts list on page 15. The sealing cup has a 32mm outer diameter and the glow plug is rated at 24V. Verify the effective machine number column to confirm these parts match your serial range. When ordering the full head assembly, also review the cylinder head cover section on page 12 for associated gaskets and fasteners.
Manual Section: Cylinder HeadTiming chain and gear components difficult to locate across multiple catalog sections p. 30
Start with the timing gear case and flywheel housing exploded view on page 30 for case, cover, and seal part numbers. The crankshaft gear (44 teeth) and crankshaft pulley (147mm outer diameter) appear separately under the crankshaft section on page 28. Compare both sections and note any interchangeability symbols before ordering to avoid discontinued components.
Manual Section: Timing Gear Case and Flywheel HousingWater pump and cooling system seal kits not clearly grouped in parts listings p. 40
Pull up the water pump and corrosion resistor exploded view on page 40 for pump body, impeller, and seal part numbers. Thermostat and housing components start on page 42; water piping follows on page 44. The cylinder block water drain plug uses a PT1/4 thread (page 19). Review each section individually, as cooling components span four separate catalog sections.
