Removing Mower deck pulleys

[Brockport Bill 2,481]

here's a new angle on removing mower deck pulleys from spindles that have been "rust welded frozen" on the spindle shaft.

i have participated in numerous threads on this topic and am back in situation again  -- using penetrant, map gas etc -- the two crow bars - hub puller etc. no luck !!!!!!

 

It was suggested to me I need to get pulley collar hotter - and was suggested to use " Heat Induction Bolt Remover" -- or also maybe called "Induction heater" --- Has anyone used this tool to heat and remove the deck pulleys?

I watched one video and the guy said when removing a nut the heat process will destroy the nut.

 

Does that suggest the collar on top of pulley on the spindle shaft would be deformed ? I don't want to have to get new pulleys but if that's necessary then I guess that's the cost of removing the pulley ?

 

any insights from anyone using this Heat Induction tool method? thanks

I've never used one, but I have seen induction heaters used in production processes.  The induction heaters are capable of heating things to a bright orange - hot enough to mess up any heat treatment the heated piece has.

 

Chances are a heat induction bolt remover won't get quite that hot.  It probably has an adjustment for the heat level.

I have this one and it does indeed work well. I have not used on mower deck pulleys but see no reason why it wouldn't work. It has helped with a few "frozen bolts" though. I like it a lot better than haveing to use an open flame for heat.

Cut four wooden wedges from hardwood, place two of them under one side of the pulley where the tip of one is over the tip of the other, do the same on the other side of the pulley. tap on each wedge going from side to side so the upward pressure will be even. Continue driving the wedges in until they are as far as they will go. put the nut on your spindle shaft to protect the threads and give it s good hard hit with a BFH tool. The pressure from below and the shock to the shaft should do the job.

@Brockport Bill    ever use a WONDER BAR ?  2 of them  one one either side , of the pulley hub , 90 deg  swing on bottom , push them both  OUTWARD  / AWAY  FROM MOUNT  POINT , solid swing leverage  , makes for  easy  removal ,also a perfect time to  do a related , bearing clean out  ? lubrication failure , LUCAS  X TRA HD GREEN CHASSIS GREASE , 550 deg flash point , polyurea rated , stays with bearing . all my decks , and mule drives , as well as  pto cone , needle bearing , have this , never  burned out a clutch disc, that pto  lever start , is a gold mine for improvements , pete  .q=wonder+bar&rlz=1C1CHBF_enUS866US866&oq=wonder+bar+&gs_lcrp=EgZjaHJvbWUqBwgAEAAYjwI

upon your suggestion couple yrs ago i got two bars and try using them after penetrant and heat but bars still wont break the bond --

i just watched a  couple videos of this tool -- plan to order if i am not successful one more day of penetrant and map gas heat -- and using wedge technigue to pry them off from underneath - - if not i plan to buy the heater tool -- just hoping it doesn't deform the collar on the top of pulley and make the pulley unusable????? thanks for info
