For anyone servicing or supporting a PT6B-37A, this Pratt & Whitney PT6B-37A Illustrated Parts Catalog is the document that turns a physical engine into a structured, part-numbered bill of materials. Every module of the engine is expanded into its subassemblies and detail parts, with attaching hardware (bolts, washers, nuts, packings, retaining rings, inserts) listed alongside the parts they secure. Service Bulletin and Spare Parts Bulletin references (pre- and post-) are carried in the nomenclature column, so effectivity changes are traceable – for example where the fuel control, oil filter element, chip detector, air inlet screen, exhaust duct sealing ring, scavenge pump housing or thermocouple lead have been superseded. A full Service Bulletin List and Spare Parts Bulletin List are included at the front, together with a Part Substitution List and Options table (IC numbers for nut options and reduction gearbox options). Because the catalog is illustrated, the exploded views let you confirm orientation, adjacent items and unit quantities before ordering – a plain text parts list cannot do that. The Numerical Index lets you look up a part number you already have and find the figure, item and quantity required, while the illustrated breakdowns let you work in the reverse direction when only the location on the engine is known.

What this parts catalog lets you do

• Identify any external line, valve, sensor, tube, bracket or connector on the PT6B-37A by ATA section
• Break down the reduction gearbox, compressor, combustion, turbine and accessory gearbox modules into serviceable subassemblies
• Read off the correct part number, quantity per assembly and effectivity code before ordering
• Cross-check a part you already hold against the Numerical Index to find where it fits
• Confirm what changed between pre- and post-Service Bulletin configurations
• Find the interchangeable or option part numbers via the Part Substitution List and Options table
• Support parts requisitioning, issuing and inventory checks with the exact P&WC basic part numbers

Why it matters

On a turboshaft engine like the PT6B-37A, ordering the wrong dash number or class of a part is not a small mistake – bearings, vane rings, shroud segments, seals and balance weights are all selectively sized and are identified by class suffixes in this catalog. The IPC makes that distinction visible: where a part is offered in a range of classes or oversize/undersize dimensions, the class is shown, and where interchangeability is restricted by a Service Bulletin, that restriction is stated in the nomenclature column. It also warns you where two parts must be fitted as a set – for example the loop clamp and rubber grommet pairs, and the compressor rear hub assembly items that are not individually interchangeable across the Service Bulletin boundary. Working without that information risks an unserviceable engine or a rejected part on arrival.
