Replace bearings in Hotpoint WM64 washing machine |
|---|
| message from Technical I.T. Ltd on 21 May 2004 |
After 8 years of service (ok not completely trouble free but thats another
story ...), the bearings on out Hotpoint WM64 have finally gone.
Their is rusty water on rear housing of drum, the drum "clanks" when lifted
vertically. I have got the front off and can see the inner drum, now just
need to undo the rear external nut holding the inner drum in place. Its
30mm, ok, I've got a socket which fits (thank you Draper, money well spent),
but obviously the drum rotates. I've tried holding the inner drum with my
other hand (spring twangs but no joy) any tips on getting this bad boy loose
?!?!
Many Thanks
Toby

Thanks BigWallop and Lurch for the advice, it worked in the end ...
I used a 30cm bar connected to 30mm socket, jammed a hammer handle between
drum and pulley. But no matter how much a walloped it no go. Reflecting back
on my physics lessons, I ended up using half the metal tubing from my Vax
hoover as an extender bar !! Nut turned real easy, didnt need to wallop it.
I remember having to use same method for front hub on my Honda when I
replaced the disc cylinders ...
Now, I would have thought the pulley wheel would just slide off the rear
bolt, or I could pull the inner drum out. Jeez this thing must be welded ! I
know my bearings have seezed but ...
I've tried walloping the rear bolt, tried pulling and jolting inner drum but
no joy.

Ah, the pulley wheel unscrews ...
Many thanks for the help

I was about to say that!
Glad you've sorted it.

Have you undone the locking tab of the nut ? It should be a metal strip folded up
around part of the edge on the nut. Are you tuning it the right way ?
|
| Technical I.T. Ltd replied to BigWallop on 21 May 2004 |
Nope, no locking tab. I am assuming the default lefty loosy, righty tighty
here, cant quite see the thread, its not a reverse thread is it ?
|
| BigWallop replied to Technical I.T. Ltd on 21 May 2004 |
It depends on the machine now a days. Can you run a finger nail around an exposed part of
the thread. You should feel your finger being drawn in or pushed away depending on the
turn direction.
Is the nut self locking ? Looking at the nut, does it have a plastic insert in the thread

I carved a piece of softwood so that it was narrower at one end than the
other, making a wedge that fitted between two of the pulley spokes and
into a recess in the back of the tub. My hotpoint has a left hand thread
but yours may differ.

What you have to do is hold on to the pulley, whilst giving the
breaker bar, (I assume you're using one of those and not a ratchet
based thing), a good braying with a solid object. If you have a helper
it's a lot easier.

Ok, got the breaker bar bit (I was using a rachet but I have a breaker bar).
But the braying ? I have to hold a solid object aloft and shout at the
breaker bar ?!
If you mean wallop, I'll give it a go, its just holding the (very sharp !)
pully and stopping it rotating, do engineers have a "special tool" to do
this ?
Many thanks for replying.

Yes, it's called the handle of a hammer, or the shaft of a big spanner, jammed between the
moulding of the outer drum and the pulley wheel.
|
| Lurch replied to Technical I.T. Ltd on 21 May 2004 |
Yep, that's the one!
A block of wood wedged in the right place can do the job. I usually
carry a 2' piece of 2"x2" and a metal bar in when doing this job.
