Topic: IPSO W234SC Bearing issue

1.  IPSO W234SC Bearing issue

Posted 03-17-2017 23:29
I am in the process of replacing bearings and seals on an IPSO W234SC washer that has a double front bearing.  The drum came out with no issue with a 3 arm puller.  The rear bearing blew apart so that came out with no problem either.  The front two bearings are a whole 'nother issue.  I can't seem to get them loose.  I tried heating up the bearings with MAPP gas, spraying with JB Weld, pounding them out and using a puller.  Note that the C clip has been removed and I was able to move the rear of the two front bearings into the front one.  A chipping hammer has been recommended but I am concerned about damaging the outer drum or housing.  I am also thinking about trying to cut the bearings with a grinder or sawzall.  I was told not to remove the housing because of the machine age.  HELP!!!

Well, what type of puller are you using to get the bearings off the shaft?  Are you using a clam-shell bearing separator? 

MAPP gas torch typically won't get bearings that size heated hot enough to cause enough expansion to get them loose, need acetylene-oxy to get it good and cherry red.  Also make sure you ONLY heat the bearing inner race, NOT the shaft(wrap a cold wet rag around the shaft near the bearing to help keep the shaft cooler).  Remember, you're trying to heat the inner  BEARING race, not the shaft.

If you decide to cut it off, you will need a high speed grinder/cutoff tool to get thru the bearing races, as they are hardened.  A sawzall won't touch it.  Cut a slit in the bearing outer race, and split it apart with a chisel(wear eye protection during ALL these operations).
Hope this helps.

Greg,

Thanks for the detailed response but the bearings unfortunately are not stuck on the shaft.  They are stuck inside the housing.  The drum came out with no problem and left the bearings behind.

I believe you have to knock out the first bearing then remove a ring that is between the two bearings to get the second one out.

If there is a ring in between the bearings, how do you get the front one out?  They are touching each other.  I removed the front ring with my snap ring pliers.

As far as the "leave it to the pros" comment, I agree with some things but I have been doing 99% of my repairs for about 15 years without much issue.  To each their own.

This one is a mechanical issue that needs heat, technique and some brute force.  Just need help from someone who has had a similar problem before.

You stated you moved one bearing until it hit the other. you need to get chisel between the bearings. You probably have to knock second bearing back to original position from the front and start over.

THATS WHY BEARING JOBS ARE BEST LEFT TO THE PROS. I LEARNT IT THE HARD WAY. 

AND WHEN THEY ARE BACK THERE. CHANGE MOTOR BEARINGS AND BELT. 

IF YOUR MACHINE LOOKS GOOD. LIKE NICE CLEAN SOAP DISH. NO TORN OVERLAYS. 

THEN YOU GOOD FOR NEXT 10 yrs. 

sorry for caps. But trying to get my point across!!!

Greg & others,

Has anyone tried a "Plasma Cutter" instead of grinding or oxy-acetylene on the shaft sleeves to remove them for a brand new shaft sleeve?  We have always just used a good grinder & abrasive wheel on our Wasco Gen4s & always remove & replace the stainless steel shaft sleeve.

It might take a bit of plasma cutting skill & a quality machine (& nozzle etc) available but ... I can't help wondering.  Any thoughts?

James, 

maybe you could shrink the bearings down with dry ice, and torch the housing a bit to expand it. 

But it the easiest answer is to buy another housing.

Paulie B,

I don't know if a replacement housing is available.  The next plan is to remove the housing and take it to the local machinist.  He has a press that can (hopefully) safely remove and replace the bearings.  Wish me luck.

Just looked it up and a new housing is $1,200 plus.  OUCH!

take the housing out and put it in a press it will move or use  TRY a muffler gun  slow speed and use a punch end tool and air punch the bearing  out of the housing

You still need to get that retainer ring out from between the bearings.

Ok, if there is a retaining ring between the bearings then how do you remove it?  I have two different manuals from IPSO and one shows a total of 3 rings and another shows 2.  I don't see a ring in the rear but there was one in the front.  It doesn't make a lot of sense to have a retaining ring between two bearings if there is not a way to remove the first or second bearing.

Larry,
         I was thinking about plasma myself, I don't know what the outcome would be with stainless and air plasma.

I was also thinking of some type of inductive heating that would heat the sleeve itself quickly, without heating the shaft and thus being able to slide it off......

Attach a photo of the housing, so we can see what the possibilities are.....

Check out (IPSO bearing replacement) on Youtube. Is that what yours looks like?

Chris,

Yes it does.  I need to get one of those orange jumpsuits!  I originally was trying to remove the front most bearing first and it wouldn't budge.  It looks like there is a ring in between the two front bearings but you don't need snap ring pliers to remove it per the video.  It sure looks easy on a brand new machine.  I'll mess with it again tomorrow.  I still think that I am going to have to remove the housing or worst case scenario replace it.

Always looks easy in the video's. Yea it looks like you need a long punch to angle in between the two bearings. You may have to try to knock the back bearing back into place from the front to make some room for your punch. By the way, i don't think heat is going to help here. You will end up heating the housing also. You need a pretty heavy hammer and a punch long enough to get a really good hit. Good luck.

I agree, you will probably have to knock the second bearing back to original position to get enough "bite" on that front bearing from the rear.

What a stupid design, I see no reason for that intermediate lock ring.  Wouldn't a washer,  spacing the bearings apart, do the same thing?(the outer snap ring would then secure both of them).  Then you could simply push both out together.

I played with it a bit today.  I drove the middle bearing back to its original position.  However, I was not able to get the front bearing to move.  The plan is to try again tomorrow AM and if it doesn't work then I'll remove the housing and take it to my favorite machinist.  If he can't press them out, he will build a tool to remove the bearings separately and I will have it to use in the future.  Agree that it's a lousy design.  Thanks all for the help.

Success finally!  I was able to drive out both bearings with the ring (not a C, but a large washer) in between.  The tolerances on this machine were very tight.  Thanks to all for the help.
