Armed with the service data supplied by Paul we can begin.

First remove the lint filter at the back of the drum, exposing the 3X screws holding the back bearing plate in place.

But first remove the outlet hose attachment at the back of the cabinet.

As per the instructions the machine was placed door face down on the floor, well not quite, placed face down on a large plastic storage box, protecting the door and raising it up a bit to save my back.

Right, need to remove the 6 bolts on the under side which secure the sides of the cabinet to allow it to splay so the drum can be extracted from the machine.

Here I need three pairs of hands, one to hold the cabinet splayed, one to hold the jockey at it’s slackest to allow the drive belt to slacken and the other hands to lift and extract the drum.

Some shouting and swearing later the drum is free.

The first major problem to over come, the front bearings have all worn away, the machine has been used for many hours in this condition causing a massive amount of friction metal drum lip on metal bearing strip causing the strip on the heater housing to wear so thin it has cracked.

The heater unit has also worn on the outside edge which acts as a ducked for the hot air due to the bearings.

This must have been such a screechy machine got to have been deafeningly loud.

well done Lee I see the visit to Mats has inspired you and as the weather is improving tis the time for these sort of jobs.

You have had stuff re-powered before I remember so when this comes back it will be a perfect match for your other Hotpoints.

And I am sure other group members can help with spare bits and pieces.

Good luck
Gary

I'm also trying to refurbish a 1701

 A couple of questions please?

Firstly is it a "brushless" motor?
(I don't want to strip down more than I need)

Secondly is there some way of renewing the bearings at the door end of the drum?
The ones near the air outlet look ok, but I think the door end ones could be dodgy.
I hope I've managed to get a set of belts which could be the main problem but ????
great series of photos very helpful, Thanks.

Cheers Bob E

Hotpoint dryer continued.....

 I'm an idiot!!! Of course its an induction motor and no brushes..
Great! I don't have to start filing down wrong sized carbons and at last run, the motor was, I thought fine.

My problem is now whether there is some way of repairing/renewing the door end bearings of the drum? If required?
Here's a couple of pictures of the bearings at the exhaust end. I guess replacement spares are out of the question.
As yet I have little idea of what the door end drum bearing arrangement looks like.
I'm spraying the bearing surfaces with PTFE spray to, hopefully, reduce any friction.(Might be a waste of time)
I'm not going to take off the base to "splay" the case and remove the drum until the new belts arrive from Ransoms.
Cheers Bob E
