Industrial Maintenance that holds 98.1% availability in dust & heat

Reactive maintenance costs 3–5× preventive in Kenyan plants we audit. A Thika packaging line called at 2am after a gearbox seized — KES 2.1M lost output + air freight + supermarket penalty. Root cause: a KES 3,200 bearing a 30-minute vibration check would have caught 3 weeks earlier. At Kwale, 340t excavators went 91% → 98.1% availability with 250h service + oil analysis (42 samples/90d).

Dynatec doesn’t sell a binder and leave. For KES 85k/month per line (Nairobi metro), you get 1 visit/week (2h) + 24/7 phone, quarterly vibration + thermography, spares kit held in Ruiru (24h dispatch), monthly report (MTBF/MTTR/availability + next 30-day plan), and training for 2 operators + 1 artisan on alignment. You don’t chase subcontractors — you get one number.

Most plants start with C assets because they’re easy. We start with A — the line that stops if it fails. That’s where the 2.7× ROI lives.

The myth is that preventive is ‘extra cost’. The audit says it’s avoided cost. We logged a Nakuru mill with 22 ‘minor stops’ per week (average 11 minutes). None had a ticket. At KES 65k/hour margin, that’s KES 264k/week — KES 13.7M/year — labeled ‘normal’. After registry + ranking (A/B/C) and 124 PM tasks in CMMS, weekly stops fell to 6 (3 min avg) in 90 days. Same crew, same machines — just ranked, tasked, and measured. When you see MTBF rise 140h→310h on the monthly report, PM stops being a cost and becomes a profit line.

Oil tells the truth before vibration does. At Kwale, 42 oil samples in 90 days caught 3 early warnings: iron 87ppm (gear wear), silicon 28ppm (dust ingress), water 0.5% (seal). We changed filters, resealed breathers, and flushed — no catastrophic failure. Without oil analysis, that’s a KES 4.2M final drive at 1,800h. With it, it’s a KES 18k filter and 2h. That’s predictive — not because it’s fancy, but because it’s cheaper than a tow at 2am.

CMMS is not software — it’s discipline. We use Fiix (or your CMMS) with QR on machines, Swahili tick-box, and photo guides. Operator does daily (5 min): oil level, temperature, sound, leak. Artisan does weekly (45 min): tension, alignment check, filter, greasing. Overdue is red on the phone. At Thika, completion 38%→94% in 60 days because it was tick-box, not essay. When DOSHS asks for maintenance logs, you print — not panic.

You don’t need a bigger team. You need a spares kit on the shelf and a report that shows MTBF climbing. That’s Dynatec maintenance — 250h in-pit service, 38 checks, 1.5h avg, zero missed in 90 days at Kwale, Ruiru→Kwale 24h consignment. Availability is not luck — it’s kitting, oil, and a tick-box.
