Hi! Can’t thank you enough for the easy how-to on timing gerotor/geroler motors. First time tearing one apart(re-seal motor) and kept confusing myself following the manufactures repair instructions. I was about fed up with trying to decipher their gibberish and had about given up till I can across your instructions/tips on using some compressed air and how the “pocket expands”.
If you get into rebuilding/timing another, maybe add some pictures facing straight down where readers can get a slightly better picture of the internal ports and orientation of gear set? Otherwise, thanks for the tips!

Hey, I’m working on a small wireless hydraulic pressure project we’re building for our backyard roll former and wanted your opinion. I’ve been looking at the Nordic nRF54L15 because it has Bluetooth LE, very low power use, and a built-in ADC up to 14-bit resolution. On a 0–5000 PSI range, that’s about 0.3 PSI per ADC count ideally.
The plan is to use a 0.5–4.5V pressure transducer, scale the signal into the ADC range, read it directly with the Nordic board, and send the pressure wirelessly without needing a separate ADS1115. We’re trying to keep parts count, enclosure size, wiring, and battery draw low.
This is going on our hydraulic roll former for pressure monitoring, load changes, and possibly pressure logging during rolling and shearing. Have you used the nRF54L15 or similar Nordic chips for hydraulic sensing, and would you trust the onboard ADC for this?
