done this many times. need a 150 ton pancake jack and TWO rosebuds.also blocks of wood between prop and nut so when prop jumps off it will not f..k up the nut.
from heating it? it's a maganese bronze alloy, which does very well with heat. as far as balancing is concerned, the prop shaft doesn't spin over 300 rpm so balancing is not required. But good quesitons.
@@machinist1337 I have been watching several other videos about various sized ships and every one shows EXTREMELY accurate and NON impact placement of props on the shafts and a couple where the assembly crews working on Panamax style ships had to remove the prop because the foreman from the owner company was not there to supervise the placement of the prop so he could assure there was zero damage regardless how minor during the placement of trhe prop to its full depth on the shaft. If the guys are so anal about a 22.000 lb prop on a 1 ft diameter hardened steel shaft, what these guys are doing would give the foreman on the supersized ship a full blown heart attack!
@@Gizmologist1 to a certain extent you are right. The large ships have documented procedures for on how install their 1million dollar propellers. These guys using a hammer on the blades is not standard practice. But using heat and driving the prop up the taper is standard practice. Instead of hitting the blades they should have put more heat and used a bigger hydraulic setup.
Hitting the blades on no no wrong place to hammer on need two torches the three torches to heat that thing up and people may not know this but paraffin wax works good on getting things off sometimes better than PVC blaster
If the prop has a higher rate of expansion then the shaft material it will expand when heated enough to loosen the grip. A reasonable sized puller to apply a constant pressure and well placed shock against the hub with A hammer should work .Beating the blades just does damage and rings like a bell. Big prop hubs are A big heat sink and the blades act like cooling fins. Use multiple torches to get a lot of heat into the hub and then hit the hub with a few well placed hammer blows. If the prop and shaft are the same material (bronze) Then you need a BIG PULLER and try rapid heating and hammering. Some times setting a Puller very tight and heating and striking and leaving it for an hour or over night will pop it unattended .

Need quicker heat on prop..slow heating will allow shafts to warm also...several torches should do evenly placed around hub... stronger strong back (without deflection or bending) would also help
C17H25N Worked for 35 yeas in the Marine repair industry pulled just about every kind of props you can imagine. from 2 lbs to 25 tons. Used rose bud to internal hydro. But I cringed when I saw that moron smacking the blades WTF. as a supervisor on the job I was the only one to swing a sledgehammer and it was never anywhere near a blade.
nothing more annoying/painful than trying to remove a prop. if the prop is taken off annually its fine. but if its not been off in years... WOOOO! WEEEE! now you have a fight! nothing beats heat, torque and a good tap though.
OK then expert. How would they fit an induction coil around it? I see three big reasons why they couldn't - blades. Are you really that stupid? They had gas to hand and so they used it - why would they have even more gear laying about?
Yes but sometimes they just don't want to come off ,we heat them at 3 o'clock and nine o'clock only so the shaft doesn't get too hot ,then hit hub to shock the thing off .
@@pauldavidson6321 heat the Bearings inner ring not the shaft... When you pour the water on it... The inner ring will expand becase there is little play between inner ring and balls
@C17H25N Hitting the blade so far from from the center does not seem like a practical method of exerting the most force to get the prop off the shaft. Exerting force as close to the shaft would be be the most sensible move if you follow the basic laws of physics.
@C17H25N Why would you not use a forked wedge around the shaft to push the porop straight off? That method is used elswhere in removing gears and flywheels that are swedged on a shaft.
@C17H25N The shaft is likely clamped down to the stands it is setting on. it seems apparent that using a jig between the support rig and the back side of the prop and exerting an EVEN force all around the shaft, combined with the heat they are applying, would exert a balanced force and not subject the prop to sudden impact. The large gear pulling rig they have could also be made with a hydraulic rig to exert a steady, non impact force on the full circumference of the prop.
i agree,being a Millwright myself i would use another method,one good method is using high pressure water,around 2000 bar,injected into the hub and into the morse taper,however the hub has to have provision for it ie a threaded hole on either side of about 3/8" BSP thread and high pressure hydraulic fittings and hoses.
what are you talking about yes they would. i worked ina shipyard for 11 years i have a formal apprenticeship and taper fit propellers like this are heated on.

WOW, the comment field is full of engineers and all are experts on bronze propellers 🧐
Good job ! 👍
Se pone calentando y se saca igual el material dilata y suelta.de ambos lados se calienta se usan hasta tres sopletes
morse tapers must be attacked from the back ,pullers tighten them. slight pressure from the back and a good whack midway on the taper always works.
Who said that's a tapered shaft?
It's a straight shaft you idiot. It's on tight that's all.
@@jackking5567 u fucking idiot all the ship drive shafts ive worked are a morse taper.
If you can't get it with a straight pull, it's time for the "BIG BLUE" wrench........ works every time!
Hitting the blades will affect the propellers settings.never hit the blades with hammers.

I have never worked on bronze propellers but they look like they know what they are doing.
À mecânica é muito bom
if the shaft had a hole that would carry oil until the middle was easier to remove the propeller
But it doesn't so what a stupid comment.
Might as well have said "Be far easier if the propellor was loose". Idiot.

because of your lack of education, I can only say that you are in the right place doing donkey service.
Why worry about damage to this blade caused by hammer blows? It’s going to be melted n cast into new one.
