I run 0000 and 0600 rounds logging top drive gearbox temp, mud pump crosshead oil, and drawworks brake cooling flow; I keep it on a one-page sheet that flags anything out of range. Anyone have a cleaner template or grease volumes/intervals you trust for a TDS-11SA when it’s -15°C and the iron’s running hard?
I tightened ours up by adding a “delta vs last round” column and one hard redline per item so the sheet stays one page without the noise. For the TDS‑11SA in −15°C we grease the quill spline about 25–30 g of NLGI‑1 synthetic every 12 hrs and run synthetic ISO 220 in the gearbox — works well but defer to your IOM if it conflicts. You running the NOV cold‑weather kit or just heat tracing and “doghouse” air on the case?
For the TDS‑11SA at −15°C, we run NLGI‑1 arctic grease and stick to “half the volume, twice the frequency” — about 15 g on the quill every 6 hrs and 8 g on the washpipe every 4 hrs — and it killed our cold‑start torque spikes; you on NOV seal pack or aftermarket?
Quick win: add an “ambient delta” column so your top drive gearbox line reads “temp − outside = Δ,” and hard-flag if Δ jumps >35°C on the 0000 or 0600 rounds — catches a cooler starting to plug before the gauge creeps. For the “drawworks brake cooling flow,” log a 10‑sec bleed‑to‑clear time each midnight round; air in that loop at −15°C drives me nuts and that number shows it first. If you want a cleaner sheet, I’ve got a one‑pager with QR next to “crosshead oil” that opens min/max and lube points — want it?
I’d add a strokes‑per‑cc line for each mud pump: ‘strokes this interval ÷ crosshead oil added’ and hard‑flag if it drifts >15% on the ‘0000/0600’ rounds — caught a sticky sight feed () before it wiped a pin. Caveat: only works if your stroke counters are clean and you measure adds, so I use a 60 cc syringe for top‑ups. Do you already log strokes per pump per interval?
