Powerplus D155B-II Parts Catalog – 483 Pages of Factory Part Numbers

If you’ve ever ordered a replacement hydraulic line only to find it’s an inch too short, or chased a seal part number through three aftermarket catalogs and still got the wrong one, you know why this manual exists. The Powerplus D155B-II Parts Catalog is the factory-issued parts list for the D155B-II bulldozer. It’s not a reprint, not a third-party compilation — it’s the exact document the dealer uses to pull parts from the bin. 483 pages of exploded diagrams, reference numbers, and OEM part codes. No skipping. No “call for details.” Every fastener, gasket, and wiring harness is listed.

Engine and Electrical System – 483 Pages of Part Numbers

Section 1 (starting page 9) covers everything bolted to the engine block and the electrical system that runs it. Engine mount, power take-off, flywheel and flywheel housing, fan and belt, intake and exhaust assemblies, fuel control lever and linkage, brake pedal, radiator, radiator fan guard and net, oil cooler, fuel tank and piping, battery, gauge panel — and the electrical system (page 64). That’s over 50 pages of engine-related parts alone. If you’re rebuilding a D155B-II and need the exact fuel injection pump mounting bolts, you’ll find the part number here. The manual doesn’t tell you how to install them — it tells you which ones to order. Pair this with a factory service manual for the torque specs, and you’re set.

Does This Manual Cover the Torque Converter and Transmission?

Yes, Chapter 2 (page 69) dives into the torque converter and transmission. Torque converter housing and regulator valve, turbine shaft and stator, torque flow transmission case, planetary gear and shaft (two sub-sections), transfer case, transmission control valve, cover and valve control lever, pressure regulator valve, gearshift lever, transmission pump, transmission oil filter, and converter piping. These are the sections you reference when a seal blows or a gear fails. Every planetary gear in the PTO is identified by OEM number. When the transmission pump goes, you get the right cartridge, not a generic substitute that cavitates at high load.

3 Reasons You Need OEM Part Numbers

1. Safety-critical fasteners: A grade-8 bolt and a grade-5 bolt look identical but shear at different loads. The catalog lists the factory-specified bolt grade and part number. You don’t guess on track bolts or final drive hardware.
2. Electrical compatibility: The D155B-II uses specific connectors and wire gauges. Page 64 diagrams the battery, gauge panel, and electrical system. One wrong sensor connector and you’re chasing phantom codes for a week.
3. Aftermarket cross-references fail: Third-party listing sites often mis-label parts by 2–3 mm. The factory catalog eliminates that. You get the exact casting number for the flywheel housing, the precise seal size for the oil cooler.

Get the Right Part Number Before You Order

Before you call the dealer or punch a number into an online parts counter, open this catalog. Locate the assembly, find the reference number, and read the OEM code. It saves one return trip minimum. If you’re rebuilding an engine on a D155B-II, the section on engine mount (page 10) and power take-off (page 12) lists every bracket, isolator, and bolt. Don’t assume the local supply house stocks the correct intake gasket — check the parts book first.

Transmission Section: Planetary Gears and Shafts

The planetary gear sets in the D155B-II are split across two sub-sections (1/2 and 2/2). Each page shows the gear arrangement, bearing number, and thrust washer thickness. If you’re rebuilding the gearbox after a hard shift, you need the correct clutch pack and piston seals. The catalog lists them by page number (82 and 88). The transfer case section (page 94) covers the high-low range shift mechanism. No aftermarket manual provides this level of breakdown — only the factory parts list.

FAQ

Is this the same as the service manual?

No. This is a parts catalog. It lists part numbers and exploded views — not repair procedures. You need the service manual for torque specs, fluid capacities, and installation steps. The two manuals work as a pair: the service manual tells you how to take it apart, the parts catalog tells you what to order.

Can I use this to order parts online?

Yes.

Every time I see a technician waste an afternoon chasing the wrong part number because they used a generic list, I point them to a factory catalog. The Powerplus D155B-II Parts Catalog stops that nonsense. 483 pages of OEM numbers. Engine, electrical, drivetrain — it’s all there. Access the Factory Manual and start ordering the right parts today.
