Shaft grounding Earthing the propeller shaft to the ship's hull prevents corrosion and spark erosion in the shaft bearings and gearboxes. The earthing is provided by spring loaded silver graphite brushes, and monitored by a compact mV meter. Why earthing the propeller shaft?
Apply Compound to Shaft. Step 4 – Remove the key and apply a liberal amount of valve grinding compound to the shaft and slather the area where the prop will sit. The process of lap-fitting your prop to the prop shaft taper makes certain both the shaft and prop mate together on the taper well leaving no high or low spots. By lap-fitting you achieve the maximum shaft to prop mating …

Lap-Fitting a Propeller to a Shaft Slide The Prop On The Taper Step 1 – The first step is to slide the prop, or prop hub, onto the shaft without the key. Be sure the shaft & prop hub are clean. Once it's been slid into place, and seated as deeply as it will go, mark around the leading edge with a Sharpie marker, as seen in this photo.
Grinding, Polishing & Straightening of Stainless Steel Boat Propeller Shafts for the Marine Industry Because of our many years of consistent performance, a client in the marine industry contracted with us at Centerless Grinding Service to grind, polish, and straighten a pair of stainless steel propeller shafts.
Precision finishing of a propeller shaft is critical to its performance, as even the slightest flaw could cause the shaft to rotate off-center and produce unwanted vibration. Constructed from high strength 17-4 stainless steel and measuring 32' length, finishing these shafts was a challenging task. The technical skills of our grinding ...
Page 2-Discussion Proper Propeller Fit Engines. To fit the prop to the shaft I use a stepped-reamer to do the job. I have a metric reamer and an SAE reamer, perfect fit, and even with 1/4" shafts I still give the hole a clean up with the reamer.
Apply gentle pressure and rotate the propeller on the shaft 90° to the right, then 90° to the left and repeat this several times. Occasionally remove the propeller from the shaft and wipe out the valve grinding compound and visually inspect the bore. Continue this until a …
When you see the inside of a prop with rings or high and low spots it was not reamed or lap fit properly. The mating of the two surfaces is actually very simple to do. They fit to each other through the act of rotating the prop around a locked shaft with the valve grinding compound in-between the two surfaces.
Crankshaft grinding is a methodical yet important part of engine remanufacutring. Today, CNC machinery can grinding and polish a crankshaft in a matter of minutes however doing it the manual way provides room for performance upgrades and …

The shaft carries a grinding disc 18 and is together with said grinding disc adjustable in axial direction relatively to a stationary grinding disc 20. The grinding discs 18, 20 are encased in a grinding casing 22 and the grinding produce is introduced through a channel 24 disposed concentrically around the shaft and, if desired, provided with ...
Currents generated by ICCP systems and sacial anodes can enter the propeller shaft through the propeller. If left undrained, this can cause stray currents that might cause corrosion in the propeller shaft bearings or gearboxes. Our shaft grounding (shaft earthing) systems drain any current sent out by the anodes.
However, it was done standing at a bench with the shaft in a vice. Trying to do it in situ would be very demanding. I cut my new manganese bronze P-bracket with a cutting disc. It was relatively easy but again, was held firmly in a vice. It makes a lot of dust. I avoid grinding inside the boat whenever possible for this reason.
The Shaft Earthing System is essential for any vessel that has installed either an Impressed Current Cathodic system or Sacrlfical Anodes as commonly the propeller bearings, propeller tips are usually left unprotected. Which could Incur high cost during dry dock, where further repairs will need to be carried out on the Propeller.
