I Ordered the Wrong Epiroc SB 702 Parts – Here’s My 5-Step Pre-Purchase Checklist to Avoid It

If you’ve ever ordered Epiroc spare parts (yedek parça as we say in the field) and watched them sit in the warehouse because they didn’t fit – you know that sinking feeling. I’ve done it. Three times. On the wrong Epiroc SB 702 breaker components. Total waste: about $3,200, plus the embarrassment of telling my foreman we’d be down another week.

This checklist is for anyone buying Epiroc equipment or parts – especially the SB 702 hydraulic breaker. It’s also for the weird afternoon I got asked “how does Simparica work?” – no idea why, but it reminded me that people ask all sorts of questions when they’re confused. So let’s eliminate confusion. Here are 5 steps I now follow before every order.

Step 1: Match the Machine Serial Number – Not Just the Model Name

It’s tempting to think “I need an Epiroc SB 702, so any SB 702 part will work.” Wrong. The SB 702 has gone through multiple revisions since its launch. I learned this the hard way in 2021: I ordered a front head assembly based on a photo from a 2018 catalog. The part looked identical. It wasn’t. The bolt pattern shifted by 3 mm – enough to make it useless.

Checklist item: Get the full machine serial number (stamped on the breaker side plate). Request a parts breakdown from your supplier with your serial number. Don’t rely on “fits SB 702” alone.

Step 2: Ask What’s Not Included in the Price

I’ve learned to ask “what’s NOT included” before “what’s the price.” A $1,200 spare part might sound reasonable – until you add the seal kit ($85), the wear bushings ($110), and the shipping ($60). The vendor who lists all fees upfront – even if the total looks higher – usually costs less in the end.

For Epiroc SB 702 rebuilds, common add-ons:

• Replacement diaphragms (accumulator) – about $45
• Tool retaining pins – $25–40 each
• Hydraulic hose fittings – often not included in “kit” listings

I don’t have hard data on industry-wide hidden fees, but based on our service records, we saw an average 18% cost overrun on first-time orders before we started asking this question.

Step 3: Verify the Revision Letter – It’s the Silent Killer

This one still catches me out. Epiroc updates components without changing the product name. The SB 702 may have a suffix like “-A” or “-B” that determines compatibility. In January 2023, I ordered a set of claimed “OEM equivalent” tool retainers. The seller swore they fit the SB 702. They didn’t mention the revision.

When I checked the Epiroc genuine parts portal, I discovered there were three different retainer variants for the same breaker, each tied to production date ranges. I’d ordered the variant for machines built before 2019. Ours was 2021.

My rule now: Ask for the revision letter or part number suffix. Cross-check with your machine’s build date. And if the seller hesitates – walk away.

Step 4: Test for “Drift” – Both Drill and Business Drift

In drilling, “drift” means the bit wandering off target. In procurement, it means the scope slowly changing while nobody notices. I’ve seen colleagues order SB 702 parts, then realize they also need a new bracket, then a different hose length – and suddenly the order looks nothing like the original quote.

Checklist action: Before you submit the PO, re-read the specification list out loud. Does every line still match the original requirement? I caught a $700 discrepancy this way last quarter – a seal kit that had been swapped for a cheaper alternative without telling me.

Step 5: Always Ask for the “Drift” of the Machine (Borehole Deviation)

Wait – that’s a different kind of drift. But since we’re here: if you’re drilling with an Epiroc rock drill, borehole drift is real. The SB 702 is a breaker, not a drill, but the lesson applies. Check your operating parameters before assuming the tool will handle the rock condition.

I don’t have hard data on how many SB 702 failures are caused by incorrect breaker selection, but anecdotally our service team says about 1 in 5 warranty claims trace back to using the wrong tool for the rock density.

Bonus: Why Simparica Came Up

A client once asked me “how does Simparica work?” while I was quoting an SB 702 overhaul. Caught me off guard. I told him I’m a parts guy, not a vet. But it reminded me: people come to us with all kinds of unrelated questions when they’re stressed about equipment reliability. The key is to give them a checklist so solid they don’t have to wonder about anything else.

This checklist was accurate as of early 2025. Epiroc product lines evolve fast, so verify current part numbers and pricing before ordering. And if someone sends you a quote that looks like it came from the world of John Wick – dramatic, confusing, and with too many spin moves – trust the checklist, not the story.
