FAQ

Does this 3201195703 spline driver drop straight into an Epiroc RD22U front head?

Yes. It's made to the factory blueprint. Same spline form, same diameters, same length. If your front head is stock, it fits—no grinding, no file work.

How does Huatai's quality compare to the OEM part?

We start with the same steel grade and heat treat to the same hardness window. Every batch gets a dimensional spot check against a master gauge. For most reman and service jobs, it'll run on par with the OE part. You won't be pulling it out early.

I'm not 100% sure this matches my unit. What can I check?

Grab the OEM number (3201195703) off your old part or the parts book. If you've got the worn driver on the bench, send us a photo and a couple of key measurements—our techs will double-check the fit for you.

What's the typical lead time?

We stock regular sizes. For the 3201195703, usually 2-3 business days to dispatch from the warehouse. Larger quantities or delivery to remote sites—reach out with your order number and we'll confirm an exact date.

What happens if the part breaks early?

We cover manufacturing defects for 12 months from shipping. For warranty, just send us the part and a brief description of the failure. We'll inspect it, and if it's on us, ship a replacement at our cost. We also stand by our tech support to help you rule out installation or alignment issues.
