The DD22 and Its Engine Configuration
The Ingersoll Rand DD22 is a compact double-drum vibratory roller designed for asphalt compaction and light-duty site preparation. With a narrow frame and tight turning radius, it’s ideal for parking lots, driveways, and patchwork. Many DD22 units were originally equipped with the Cummins A1700 engine, a naturally aspirated inline four-cylinder diesel known for its simplicity but also its limited parts support in later years.
The A1700 was part of Cummins’ small industrial engine lineup, often found in compact construction equipment, generators, and agricultural machines. While it delivered reliable performance in its prime, the engine was eventually discontinued, and parts availability became increasingly scarce.
Symptoms of Engine Failure and Initial Diagnosis
In one documented case, the A1700 suffered catastrophic failure—described as having “come unglued.” Upon inspection, multiple push rods were bent, suggesting valve train interference, possibly caused by a failed camshaft or timing gear misalignment. The operator contacted Cummins for parts but was told the camshaft was obsolete, and push rods were not stocked in the system.
This led to a dilemma: rebuild the engine with hard-to-find parts or repower the machine entirely.
Rebuild vs. Repower Considerations
Rebuilding the A1700 is possible if parts can be sourced through secondary suppliers, salvage yards, or custom machining. However, the following factors must be weighed:
Final Decision and Outcome
After further research, the operator discovered that parts for the A1700 were still available through alternative channels. The initial parts inquiry had been handled by a less-than-thorough representative. With push rods located and other components sourced, the decision was made to rebuild the original engine.
This outcome highlights a key lesson in equipment repair: always verify parts availability through multiple sources before committing to repower. Many older engines are still supported by niche suppliers or can be rebuilt using compatible components from related models.
Recommendations for DD22 Owners
The Ingersoll Rand DD22 roller, though compact, presents a complex decision when its Cummins A1700 engine fails. With careful sourcing and mechanical diligence, a rebuild can restore the machine to full function. For operators facing similar challenges, persistence in parts research and a clear understanding of engine compatibility are key to making the right call.

Rebuild vs. Repower Considerations
Rebuilding the A1700 is possible if parts can be sourced through secondary suppliers, salvage yards, or custom machining. However, the following factors must be weighed:
- Camshaft availability: If obsolete, a used or remanufactured cam may be the only option
- Push rods and valve components: Can sometimes be matched from similar Cummins models
- Cylinder head integrity: Must be inspected for cracks or warping
- Cost of rebuild: Estimated between $2,500 and $4,000 depending on labor and parts
- Kubota V1505 or V2203: Compact, emissions-compliant, widely supported
- Perkins 404D series: Durable and used in many rollers and compactors
- Yanmar 4TNV series: Known for fuel efficiency and quiet operation

Recommendations for DD22 Owners
- Document engine serial numbers and part codes before ordering
- Consult Cummins technical bulletins for cross-reference parts
- Use independent diesel shops for rebuilds when OEM support is limited
- Consider repower only if block or head is cracked or parts are truly unavailable
- Keep a parts log for future maintenance and resale value
