3201195703 Straight Spline Driver – Fits Epiroc RD22U Front Head

Highlights

Key Advantages

Drops straight into the RD22U front head – no shimming or rework. Part number 3201195703 crosses to Huatai 3201 1957 03.
Spline form measured to OEM specs: full contact along the tooth flank keeps backlash tight and lowers spline wear over time.
Through-hardened alloy steel, chosen for surface hardness that resists brinelling under high-cycle torque reversals.
Heat treat process targets 50-55 HRC, balancing core toughness with surface durability for crack resistance in fractured ground.

Use Cases

Applications

Drifters on surface and underground rigs where the RD22U is the primary hammer
Mining rounds, quarry benches, and heavy civil drilling that punish drifter components
Replacing drivers that show twisted splines, spalling, or step wear during scheduled PM

FAQ

Is this an Epiroc-branded part?

No. It’s a Huatai aftermarket replacement built to interchange with OEM part 3201195703. Material spec and spline inspection follow OEM print tolerances, so fit and torque transfer match the original.

How do I check if this driver fits my front head?

Look for 3201195703 in your parts book or confirm your front head is an RD22U. If you only have the Huatai number (3201 1957 03), that’s the same part. Still unsure? Send us a photo of the old driver and the front head data plate – we’ll confirm it before you order.

What if the splines wear out quickly?

Premature wear usually points to misalignment or lube starvation, not the driver itself. Check your shims and grease supply. Our driver is through-hardened to hold its profile, but it can’t compensate for a bent chuck or dry splines.

Do you keep these in stock in North America?

Yes, standard inventory for 3201195703 is held in our warehouse. Typical dispatch is 1–3 business days. We can also ship from alternate locations if your job needs it faster.

Can I set up a blanket order or get better pricing for fleet quantities?

Absolutely. Talk to our sales desk about volume pricing, monthly releases, and consignment stock if you run multiple RD22U rigs. We’ll build a package that matches your drill schedule.
