Long shot but has anyone got a pump for above machine that is collecting dust in there garage part number 151123
will look in the morning
funnily enough that part number came up in conversation last week as one of those you just remembered because it went that often
Dave
Yes it was very common part to fail keep my fingers crossed you may have one I rebuilt this machine probably 20years ago still going strong but leaking pump
someone has the previous pump for sale on Ebay
wont fit yourson model 1504 date code 02 they introduced the motor you have and the pump. At the same time they took off the lower gearbox bearing support which meant the the lower gearbox bearing wears and starts to leak oil. This led to the pinion wearing in the box
previous motor ran at half the speed and had aluminium clutch shoes like car brake shoes. because pump was running half the speed it had 4 pump blades the later has only 2. That pump lasted that long the common fault on them was the rubber valve used to fail and bounce causing the outlet hose to pulsateit was a cost cutting exercise but a much more inferior machine
Dave
ok not got one but if you feel brave and your pump is suitable
the 4 pole and 2 pole pump were essentially the same. the difference was the impellor had 2 less fins and the drive pulley was smaller
there is a seller on ebay selling the early pump ( £16). if your pump is an aluminium base with screws holding a cover on you may be able to remove the pulley (roll pin ) and swop it over. if your impellor shaft is damaged you will have to trim off 2 of the pump vanes on the new impellor

the only reason is lasted longer was the motor was running half speed
once they all changed at date code 02 all went down hill as you know
dont think i ever changed early clutch shoes or the motor because the pump leaked. never had the early pedestal corrode and push the seal off or the gearbox lower housing wear out and leak oil
think i have a few motors sitting upstairs but am finding stuff all the time as i start a clear out to save anyone after me needing 10 skips lol

The old type pumps did leak and the clutch shoes did need changing.;) At one time the old large black box relay for the motor was mounted near the top on the inside of one of the four outer drum support brackets, directly in line with the pump. A pump leak used to spray directly onto the relay causing motor burn outs. But we are talking 1501/02/04 machines. The clutch shoes used to be a brown material which was ok. Then they changed it to a very hard green material which was not up to the job so it was changed to the last black type. The early bellows seal was fitted to a large brass counter face seal at the top of the support tube so there was nothing the water could get at to corrode apart from where the carbon face fitted under the bowl support.

they were brilliant machines to work on once you got used to them. you could get parts for the gearbox and rebuild them as the base used to wear on later ones plus the spring clutch used to go so they had wash action when it was supposed to be spinning
think it was the 1502 where the knob glowed red when it heated
Dave
I stripped many a gearbox down, the small Bendix spring you mention was available as a spare for years. I even replaced those with the power unit in situ. Propped the machine up on four house bricks and undid and removed the gearbox sump from underneath. The hardest part was trying to get the small piece of the end of the spring that was still stuck in the bottom of the sump, sometimes couldn’t get it out so drilled another small hole in the bottom plate. Also saved a few gear mechanisms to repair other gearboxes. Those where the days. 😎

Did you ever get to work on the original 1500? It had on fill that was mixed. There was a temperature sensor in the water inlet and on mid temp washes it used to pulse between hot and cold fill.

Remember trying to get a tub off one while I was training as an apprentice electrician at MANWEB. Probably around 1974. It belong to my girlfriends parents at the time and he stripped it to try and repair it. He took off the flat plate in the middle but the tub would not come off. He had even taken off the ring of bolts and taken the tub out leaving a large aluminium flange. 5 years later I know i could have got it off easily. I even dropped into a local Hotpoint depot and asked them and they suggested to cut the shaftDave
That was the old type drum with a much larger hole. The official fix for that was the power unit supplied with a plate to attach the bowl to the smaller bowl support on the new power units. You removed the old large alloy bowl support by using a cold chisel all the way around the centre.
