Title: Hoover Turbopower 2 - Troubleshooting and refurbishment
Post by: beko1987 on August 20, 2014, 09:00:49 PM
This was offered up on our vacuum collectors facebook group for free, so I paid the postage and it arrived last week

(https://lh4.googleusercontent.com/-yJUmIaldn_g/U_Td3NlPi0I/AAAAAAAAcX0/w5k28zwWdeQ/s512/%255BUNSET%255D.jpg)

Never gelled with these as much as the Turbopower 1's. These are a clean fan design, rather than the dirty fan of Hoovers of olde! Solid things though, and treated to a fresh bag, filter and belt once a year will soldier on

Plugged it in in the garden (previous owner had warned me it was broken) and had a listen

https://www.youtube.com/watch?v=l0j2jMdvkvo&list=UUv0y2E43HyJMX85p-Wxro0Q (https://www.youtube.com/watch?v=l0j2jMdvkvo&list=UUv0y2E43HyJMX85p-Wxro0Q)

Ah, sounds healthy then!

Pulled the motor out to have a look

Carbons out of the way

Top cover and top bearing off

(https://lh5.googleusercontent.com/-6MFxQWKkH9o/U_TeFdurEQI/AAAAAAAAcYM/3AUwup7YcAQ/s800/%255BUNSET%255D.jpg)

and the issue was instantly clear, b :censored:y Amtek motors...

(https://lh6.googleusercontent.com/-FLdm609Vc3I/U_TeKLjtSRI/AAAAAAAAcYU/EkaxLpnFKEs/s800/%255BUNSET%255D.jpg)

Took the rest apart to check the fancase bearing

(https://lh6.googleusercontent.com/-jPAQVcGDvys/U_TeOnuzqdI/AAAAAAAAcYc/FHznI1tBw_s/s800/%255BUNSET%255D.jpg)

I had a fancase bearing (although a new old stock turbopower 1 one from the 1980's), but the armature end one was smaller. Buggar. However, I then had a brainwave, and grabbed my little box full of dyson clutch spares, and found a nice bearing, which fitted on a treat! So, a Dyson clutch bearing is the same size as a TP2 Amtek motor one! It can take the rpm, its designed for 1400w motors.

Lashed it all together and had a test run...

Lovely! The grumble on wind down is the bearing I think, it's from an era of 440w motors, the vortex does the same as it has the same bearings fitted. Must buy some modern bearings and change them (and re-bearing all my tp1 motors whilst I have spares)

Now it was working, I could begin the stripdown

(https://lh3.googleusercontent.com/-ISMWqQuBYCU/U_TecdMxKWI/AAAAAAAAcY0/5SdHFcfo0Wc/s512/%255BUNSET%255D.jpg)

Much better! Not sure what I'll do with it, but I havent had a TP2 for a while, and it's been an easy refurb. I plan to get some better bearings, as the 1980's one doesnt like winding down from 1200w, so hopefully some modern ones will make it a bit smoother! But it's making a good upstairs machine for now!
