This Schramm T685WS Rotadrill parts manual is not a generic reference — it is the illustrated document Schramm published under part number 2741-0157 specifically for the machine built as serial J124-6937. Every figure in the book is a numbered exploded view, and every numbered balloon on those views resolves to a line item listing with the Schramm part number, quantity, and description. That structure is what makes this manual useful to an owner, a shop, or a parts counter: you identify the assembly on the illustration, read the reference number, and drop straight to the ordering data.

The book is organized into eight chapters that follow the machine physically. Chapter 1 covers the frame, outriggers, fuel tanks, and operator platform. Chapter 2 moves into the Cummins QSK19 engine installation — air cleaner, heat exchanger, hydraulic pump drive gearbox, coolers, fan drive, supports, and exhaust. Chapter 3 covers the compressor and air line circuit in both Sullair and GHH configurations, including the clutch drive material, air-oil tank, selector valves, and control material. Chapter 4 is the largest section of the book and details the control panel, the complete hydraulic circuits, and every hydraulic pump on the rig. Chapter 5 covers the mast and rotation gearbox. Chapter 6 breaks down individual cylinders and valves into service kits with seal, packing, gland, and piston part numbers. Chapter 7 collects accessories such as the welder circuit, lazy susan, pipe handling arm, cyclone sampler, and holding fork. Chapter 8 holds the electrical and hydraulic schematics.

Equipment Configurations Covered

• Engine: Cummins QSK19 rated at 700 HP @ 1800 RPM, with a 750 HP @ 2100 RPM variant listed in the miscellaneous engine parts sheets
• Compressor options: Sullair 1150/350 and Sullair 1250/350, plus the GHH CF1000H 2.8250 G 500 PSI unit
• Serial splits: sections flagged for rigs J124-5927 and earlier, and rigs J124-6028 and later, so the correct compressor connection and hydraulic tank hardware can be matched to the machine on the floor
• Optional equipment: 38 ft travel mast, outside lazy susan, auxiliary pipe handling arm, holding fork, cyclone sampler and wet splitter, 18 GPM bean water injection pump, welder

What Makes This Parts Manual Worth Having

Ordering the wrong part on a drill rig is expensive in both dollars and downtime. The Schramm T685WS Rotadrill parts manual 2741-0157 removes that guesswork by tying every component to the exact serial number range it belongs to. When a section has changed across the production run — the Sullair compressor connections, the hydraulic tank sheet 2, the pivot control panel — the manual flags the serial boundary in the figure title so you know which version you are looking at before you call the dealer.

The cylinder breakdowns in Chapter 6 are especially practical. Each cylinder is presented with its complete service kit listing: wiper, rod seal, piston seal, O-rings, back-up rings, gland packing, and piston, alongside the kit part number. For a rig that works in dust and weather, being able to reseal a mast tilt, traverse, or outrigger cylinder without ordering a complete replacement assembly is a real cost saving, and this manual gives you the numbers to do it.

Hydraulic circuit sections in Chapter 4 and Chapter 7 document the rig’s circuits with component callouts, hose part numbers with length and end configuration, and fitting part numbers. If a hose fails in the field, the listing gives you the exact 2826-series or 1666-series number to order rather than a measurement to guess from.

Who This Manual Is For

Owners and operators of a T685WS Rotadrill who maintain their own machine. Shop foremen building a parts order. Field mechanics tracing a hydraulic circuit. Parts counter staff who need to confirm a number against an exploded view. Anyone rebuilding a cylinder, replacing a compressor, or restoring a rig and needing Schramm’s original component identification.
