42” RD questions

[Sparky-(Admin) 21,489]

  Bought this 42” RD this fall, only used it twice and it seems to be eating the belt. Investigating I have discovered that all the pulleys are severely corroded and the belt groves are shot. I think the rough surface is destroying the belt. Spindles run quiet though. 
  Never removed this type of pulley before, they aren’t cast so I can only assume a 3 jaw puller would bend em up.  
  Any tricks?

Will a General Motors power steering pulley puller work? A collar locks into the groove at the top.

My FIL destroyed one of those pulleys. Heat, kroil, pullers, nothing worked. The other two dropped out when he removed the retaining nuts. 

 

The good thing I guess is they are all standard sized, so even aftermarket pulleys Will work.

What I was thinking as well.

[Bill D 1,991]

Soak with penetrating oil,  then heat.  Hold the collar on the pulley with vice grips or a pipe wrench.  Use an impact gun drive the shaft from the underside.   Only works on metric shaft pulleys and decks without a key.

Nylon insert in nut as shown means there should be a key.

Regular nut plus a regular spring lock washer no key.

Since the pulleys are shot. Slice them!

I was wondering that too...

@Sparky

Are you trying to save and clean or just remove?

  Long story short…this deck cuts well and the spindles are quiet, but these nasty pulleys are destroying the belt. 
  Decided to try and clean up the pulleys. First I chisled off the large chunks of rust, then did some heavy wire wheeling. They seem to be ok now. Will know better when I order a new deck/spindle belt and probably a new idler pulley (  @76c12091520h  ) for it and spin it up.

That one looks a bit nasty.

It’s still a bit nasty…but much better than it was.

Run em now and see what happens...

 

I'd try to smooth off that one @squonk noted a bit more...

Hhhmmm... on Colossus @ebinmaine time you might be cutting (pun intended) it close...

@Sparky   those decks are cake to refit , those pulleys easily remove with 2 WONDER BAR , pry bars , NEVER USE A PULLER ON A PULLEY !  been trying to find my write up on that , done years ago , there are  bolts under the pulleys , remove top pulley nut , use 2 wonder bars , 90 deg bend , under pulley , sitting on TOP OF DECK BOLT  , and up against pulley center  mount , strongest point of angular advantage, push pry bars OUTWARD ,AWAY from pulley , lifts right up , also a great time to re fit new bearings , with lucas  550 drop point green chassis grease , have 3 decks with this set up , no noise or failures . notice thin space of pulley to deck bolt ? thats your  wonder bar leverage advantage, pulleys lift right off , no damage . pete

@Sparky   my decks are all rebuilt , been  solid / quiet for years , not only did the top side , but have been doing this for years also , all three , also kook like this , over winter , thats how you preserve , your work , propped up to wall, with screw in eye bolt , wide S hook , 5/16 steel  to  heavy extension spring , that hot sun lubrication bake in , is a permanent part of  rustproofing , no whining noise, belts are solid and no fraying , spindles are  lucas 550 deg quiet / smooth , pete

 i had started a similar thread last year asking for help to remove frozen pulleys on a 42 rd deck left out in weather that i obtained and wanted to rescue and rehab - - i tried every suggestion made from R Sq members - penetrating oil for a week - heat  - pry bars etc -- nothing worked thus only solution left was cutting off - - see photo...

 

Certainly frustrating having to buy 2 new pulleys but the end result was a nice rehabbed deck should last for years - - good luck

  You can see on the idler pulley mounting bar how much it was jumping by the shiny section. After cleaning up all the pulleys it’s riding so much nicer!  
  Still going to get a new belt and replace the idler, it’s just a bit noisy, before she goes back into service
