Part required for Dry Roller

Post by Thundercrack » Fri 07 Jan, 2022 2:21 pm

Hi all. I have a Tullis Russell Hot Press Dry Roller. The motor appears to have died. Does anyone know where I might get a broken machine for parts, or somewhere I can order spares? Thanks in advance.

Have you looked into getting the motor re-wound there are companies who specialise in doing this and it's quite often a financially worthwhile thing to do and at times cheaper that buying a new motor.

could it be a blown capacitor? I have a planer thicknesser that I thought the motor was gone on but when I turned it upside down the capacitor was quite obviously blown. I found a replacement for around £15 on eBay. Might be worth checking before getting the motor rewound

The problem is that there’s nobody near me that even knows what the machine is for until you explain it to them. Two professional technicians have both said separately that the motor is gone but done know where to go for a replacement. Not much help to me. Starting to think a new machine would be less hassle.

Many machines use generic motors, if you can find a part number on the motor, you might find that there are available from electoral parts outlets like from here

This is true about generic motors. Not all motors get replaced with an exactly identical motor, but if the functional parameters and it can be made to fit mechanically, it is usually a working solution. I let school and became an engineering apprentice in the late 1960's. Quite a lot of equipment used by the company I was working for had been made by manufacturers, which no longer existed and motors were often replaced with make do equivalents. In the decades after the war the economy was still suffering the post war changes and manufactures, which had survived the war were still going out of business.

Money was tight and the company had staff with the necessary electrical and mechcanical know how, so lots of machinery got repaired in house, you did what had to be done to keep on working. It may have been easier then, as there where plenty of places which sold warious surplus items quite cheaply. The only difficulty was fidding something that would do. There was no internet then, just looking where you can instead, but somehow things were made to work and if not there were motor companies who used to make you something to order.

A lot is very different now, but the principle of fitting a functional equivalent is still workable.

Thanks very much to everyone who replied to my post. I will try and get the motor specifications and see about a replacement or rewind of the current one. Cheers again to all.

One motor parameter you may not have consider is the motor speed, so motors have an internal gear box and have a diffined output speed.
