Before you order a single screw, you need the "map." A parts diagram (often called an explosion drawing) is essential for two reasons:

Q: Is the Hilti SID 4 A22 the same as the SID 2-A12? A: No. The "4" indicates the torque class (powerful), and "A22" indicates the 22V battery platform. Do not use parts diagrams from different voltage tools.

Q: Can I get a printed paper diagram mailed to me? A: Yes. Call Hilti customer service. They will often send a service manual exploded view free of charge if you ask politely. hilti sid 4 a22 parts diagram free

Q: My diagram has "Rev C" written on it. Is that okay for my Rev B tool? A: Usually, but not always. Cross-check the serial number prefix. If your tool is over 5 years old, you likely need the original Rev A or B diagram. Changes in Rev C may include a new trigger design.

Q: Are there video breakdowns that use this diagram? A: Yes. Search YouTube for "SID 4 A22 rebuild" and pause the video on the parts diagram. Many technicians overlay the official parts list for reference.

Based on field data from Hilti repair logs, these four parts fail most often. If you are searching for a diagram, it is likely for one of these:

| Part | Failure Symptoms | Average Life (Heavy Use) | Approx. Cost (USD) | |------|------------------|--------------------------|--------------------| | Anvil (1/4" hex) | Bits wobble, won't lock, slippage under load | 2–3 years | $35 | | Brush card assembly | Intermittent power, sparking, reduced torque | 300–500 hours | $12 | | Trigger switch | No response, stuck on, erratic speed | 3–5 years | $45 | | Impact mechanism (hammer + cam) | Grinding noise, no impacting, low torque | 4–6 years | $65 |

Pro Tip: When disassembling to replace the anvil, use the parts diagram to note the orientation of the three rolling pins inside the impact mechanism. Installing them backward will destroy the tool. Hilti “Parts & Service” app (iOS/Android)
