Description
Peacock Automotive Dial Gauge Set BK-10
Checking bore wear, measuring crankshaft journal runout, or verifying cylinder taper demands a bore gauge that can reach deep, transfer a reliable reading, and hold its zero under shop-floor conditions — a standard dial indicator on a surface stand simply won’t cut it. The Peacock BK-10 Automotive Dial Gauge Set is purpose-built for exactly this kind of inside-diameter inspection work: the telescoping extension rods let you reach into bores that would defeat a short-stem setup, while the dial indicator transfers the measurement cleanly to a face you can actually read. This is a used set in good mechanical condition, complete with its original metal case, Japanese instruction sheet, and full extension rod complement — everything you need to get straight to work.
- Dial indicator with clear graduated face — The included dial indicator reads to fine graduation increments, giving you the resolution needed to detect cylinder taper, out-of-round, and journal wear that falls well inside condemnable limits. A coarse indicator here costs you the diagnostic call.
- Modular extension rod system — Multiple interchangeable extension rods allow the gauge head to be positioned at varying depths inside a bore. This matters when you’re measuring at the top, middle, and bottom of a cylinder to map taper and barrel wear across the full stroke length.
- Knurled centralising body — The knurled grip on the gauge body aids controlled insertion and rotation inside the bore, keeping the measuring contact on the correct axis and reducing the risk of a tilted reading that skews your result.
- Compact metal carry case with fitted interior — All components nest in a purpose-made tin case with a formed lining. For a tool that relies on delicate contact points and a calibrated indicator spring, a fitted case is not a luxury — it’s what keeps the set accurate between uses.
- Ideal for — Automotive engine reconditioning (cylinder bore measurement, crankshaft journal runout), small engine and motorcycle engine inspection, lathe bore checking, toolroom incoming inspection of bored components, and four-jaw chuck bore verification.
Condition
Used (Good Condition / Pre-owned, mechanically sound)
The dial indicator face is clean and legible, with no cracked crystal and no fogging to the dial markings — you can read it clearly under normal workshop lighting. The indicator needle responds freely and returns to zero consistently when the spindle is released, indicating the internal spring and rack mechanism are in serviceable order. The extension rods show the expected light handling marks and minor surface patina consistent with previous use, but the contact surfaces are free of the kind of damage — deep gouging, burred threads, or bent stems — that would compromise a square, repeatable setup. The metal carry case shows external wear and age consistent with a tool that has been used and stored on a working bench rather than kept in a cabinet; the internal lining remains intact and continues to protect the components. The original Japanese instruction sheet is present and readable. As with any used bore gauge set, we recommend zeroing the indicator against a calibrated setting ring or a known-good master bore of the correct diameter before committing measurements to a job — this is standard practice regardless of the tool’s age and confirms the unit is reading true before you start condemning or passing components.
Included:
- 1 x Peacock BK-10 Automotive Dial Gauge Set (dial indicator, centralising gauge body, full extension rod set)
- 1 x Original metal carry case with fitted interior lining
- 1 x Original Japanese instruction/specification sheet
Not included: Setting ring / master ring gauge (required for zeroing — not supplied), no additional replacement contact points beyond those present in the set.
Brand Information
Peacock is a trade name of Ozaki Mfg. Co., Ltd., a Japanese precision instrument manufacturer with a long-standing reputation in the metrology and automotive measurement sector. Made in Japan, Peacock instruments sit in the same recognised tier as RSK and Teclock — competent, shop-floor-reliable Japanese tooling that is taken seriously by professional engine reconditioners, toolmakers, and fitters across the Asia-Pacific region. While Peacock does not carry the same global profile as Mitutoyo or Mahr, their bore gauge and dial indicator sets are well regarded for consistent mechanical quality and durability under regular workshop use.
