I have fitted the above washing machine with new drum bearings and seal kit and re-assembled the machine.
Please note that whilst not be a professional I am not a DIY amateur and have performed the bearing change successfully before.
My issue is this – after the refitment and passing the machine over for use to my wife the machine vibration is worse than before I fitted the drum bearings.
I am confident of refitting everything correctly and would appreciate any help in identifying why I have the excessive vibration. Before I remove the drum for inspection I would like to offer my thoughts as to what the problem might be:
1)The bearings have not been fitted correctly ie fitted home up to the shoulder within the drum housing although I am 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} confident I fitted them correctly.
2)The shaft of the drum spider is worn hence the vibration.
3)On re-fitting I added a little grease to the rubbers on the drum shock absorbers / struts for easier refitment and wondered at the worse case would this affect things.
Thanks in Anticipation

Re: Zanussi FL1032B Bearings vs Spider Shaft
If you can rock the drum within the tub,that would suggest the bearings are loose within the housing,or the shaft-seat is worn.
Also consider if you hit the inner-race, you could have cracked the balls
(unlikely)If there’s no drum “shake” at rest,and you can spin the drum freely, (slip the belt off and give it a twirl)….you must have a dynamic imbalance
does it occur at all speeds? come and go? spin only?have you checked the “lifters” (I think they’re called) the bars in the drum that catch the laundry,-some are removable and a sock trapped under one would cause an imbalance.
Also, the most elementary…is the drum concentric!….if the front is offset with respect the rear, yes, it will vibrate!
finally, we ARE talking vibration and not noise , aren’t we?
Re: Zanussi FL1032B Bearings vs Spider Shaft
Hi Steve,
Thanks for the quick reply – there’s no drum “shake” at rest and yes the drum spins freely. No laundry caught in the drum lifters and the drum or the spider have not been dropped or damaged but without removing and checking I cannot confirm that the drum is concentric.We are talking vibration most definately and the vibration occurs predominantly when spinning with laundry (the right amount). Vibration occurs on other cycles for example when low rpm rotation occurs ie the first couple of rotations say after water fill and gets worse as the rpm increases.
Running the machine without any laundry and the vibration is almost negligable.
I don’t think there’s any alternative but for me to remove the drum and examine the spider shaft seat and as I have a spare 6207 bearing I’ll try and push this bearing onto the spider shaft and check for any intolerance.
Thanks so far
Mike
Re: Zanussi FL1032B Bearings vs Spider Shaft
Bearings on the 1000rpm models are normally 6204 and 6205. Did you have much bother getting the drum shaft out of the old bearings? Sometimes you have to drift out the shaft and it spreads the end so that the pulley no longer fits properly.
Re: Zanussi FL1032B Bearings vs Spider Shaft
Hello Phidom,
No trouble in removing the drum shaft – slight tap with a mallett and a piece of wood.The 6207 is definately correct as I have the original bearings fitted at the factory the 6207 and 6206 which I removed for the first time approximately 6 years ago so I know their sizes are definately correct!!
The pulley fits perfectly also!
I suspect that I have a dynamic imbalance on the drum after reflecting on the previous post.
If I have an issue with the shaft then I’ll replace it but oi the drum is not concentric then I’ll have to reluctantly consider scrapping the machine as I’m unsure if this part is available and at what cost.
I’ll be removing the drum in the morning and postt my results tomorrow evening.
Thanks
Re: Zanussi FL1032B Bearings vs Spider Shaft
You would have spotted if the drum was off-centre,just by spinning it.
It’s a given that the back is concentric, as it’s bolted/rivetted to the spider,which is integral with the shaft…and that would need a really hefty clout to misalign.
if you’ve gripped the tub-rim whilst rocking the drum(lift/drop,-not rotation)
you can do the same thing at the pulley end…try rocking it…..i doubt there’s a problem there ‘cos it spins smoothly 💡 check the belt for flats, where the original bearings were possibly causing the drum to snag or jam. If the motor-pulley has chewed it a bit, that would likely cause your problem.Re: Zanussi FL1032B Bearings vs Spider Shaft
That’s interesting about the bearing sizes. The bearings listed are the ones you have in your machine but all the FL1032 machines I’ve done bearing changes on have had the smaller ones. I’ve not done one of these for a few years now but they were a very popular model at the time.
Re: Zanussi FL1032B Bearings vs Spider Shaft
Hi Steve
Just to update you after reading your post Thursday morning – I’ve fitted a new belt and obviously that is perfect but good point about flats.After reflecting late Wednesday evening – the drum is is certainly not in balance and I suspect I may have done the “damage” when moving the machine to and from the garage before and after the repair. I’ve walked the machine but also opened the machine door to obtain a better grip for raising the machine up and down the step to/from the kitchen.
I’m still going ahead with the drum removal and as per my last post will feedback this evening.
Thanks
Mike
Re: Zanussi FL1032B Bearings vs Spider Shaft
If you remove the drum again, FIT A NEW SEAL….YES! I know it’s “new” but the lip will sustain damage,just having a sharp metal shoulder pass over it (as in the step between the bearing-seating and the seal-seating.
I still think you’re barking up the wrong tree, here.take the belt off and check the static balance of the drum……stick a bit of masking tape ti the lowest part of the lip, rotate drum about 100* let it go……drum may well revolve. when it stops,mark new “low point” -repeat.
Out of balance drum will always settle at the same point…….(try it with a bicycle wheel, the valve always goes to the bottom,provided bearings are good and there’s no counterweight)
If you DO have an imbalance,, try taping a coin to the “high” edge
I woildn’t expect a couple of grammes to make a lot of difference, though you could concievably have a ROCKING COUPLE…where the back of the drum has an imbalance diametrically opposite the corresponding imbalance at the front.
static balance is perfect, dynamic is horrendous!
💡 IIRC, you lubricated the supports?….NOT a good idea IF they’re designed to act as a friction-damper…..any vibration which is undamped is able to increase in amplitude very easily.Whatever you’ve done, enough imbalance to cause severe vibration would ,i’m sure, be self-evident…As I said before, if the drum spins “true”to within about 3/16” at the mouth, the imbalance is likely to be insignificant ,compared with the imbalance of the average random washload…………..you DID put more than a couple of towels on test, didn’t you? 😛
Re: Zanussi FL1032B Bearings vs Spider Shaft
Hello Steve,
Just read your email at 11.28am after removing the drum from the casing and then inspecting and checking.On re-assembly of the drum into the rear casing, bearings, shafts and seal all appear fine. After fitting the front casing I performed a balance check by hand albeit to guide me and it appeared to be okay.
I then fitted the pulley and rotated the drum and noted a slight imbalance on the pulley!
This is the only thing that I can find. It’s plausable that I may have done the damge when undoing the pulley securing bolt and/or when tightening. I inserted a piece of wood between one of the pulley spokes to do this and though I didn’t muder the tension it is possible that I may have buckled the pulley.
I have a short video clip of the pulley which I would like you to view but cannot post here.
1.30pm Update
Before re-fitting the drum casing back into the carcass I re-checked the fixing positions for the 2 drum casing springs and noted that I had previously fitted the springs into the wrong fixing holes. I checked the distance against the bottom support dampers to the front of the carcass to confirm that I had indeed fitted them incorrectly.I transposed that measurement to the top fixing holes to obtain the correct position.
At 1.30am this afternoon the machine is back in service!!!
A BIG THANKYOU Steve for taking the time and effort to reply!
I’m in South Manchester and if I’m in Delph, Uppermill, Greenfield – more likely the White Hart Inn at Lydgate, I’ll quite happily buy you a couple of pints.
Mike
for the springsand simply re-fitted the drum
RegardsMike
Re: Zanussi FL1032B Bearings vs Spider Shaft
pleased to hear it!…I was convinced you couldn’t unbalance the drum to that extent without noticing something!….spring POSITION didn’t occur to me :rolls:
If you’re rich enough to go in the White Hart, you should just chuck that thing into the local charity and buy a new ISE 😆Re: Zanussi FL1032B Bearings vs Spider Shaft
Too late now I know but a tip for anyone else doing this job. When removing and refitting the outer drum from the machine find yourself a couple of lengths of fairly thick stranded electrical wire. Get a flat blade screwdriver and prise up each top suspension spring so you can pass a wire under the spring hook. Wind a length of wire round each hand and use the wires as handles to lift the springs off the top crossmember and lower the drum down. If you now remove the springs you should be able to leave the wires in place ready for hoisting the drum back into place. That way you know you have the right spring slots.
