H/Point VTD00 T/Drier – vibration after drum shaft kit fit

[MickGeorge]

Hi folks.

Went to this a couple of weeks ago and fitted a drum shaft kit as drum was scraping on back. Now customer is complaining of intermitant vibration noise.

Went back yesterday and checked and sounds like the old 6lb bendix when the front felt bearing runs dry. But only does it intermitantly and then stops.

Stripped again – replaced front seal again as thought that might not be fitting propley – tested several times and seemed ok.

Customer just phoned to say it is doing it again.

Has anybody else had this problem? Fitted umpteen of these kits and never had this problem before but got me a bit foxed to what can be causing it. Juse wondered if a belt change might cure it as the old type (narrow) belt is fitted or possibly the rear circular seal is faulty and not enough lub on it? Also checked front seal/bearing housing for loose screws and they seem ok.

Any ideas or suggestions welcome.

Thanks

Mick

When I replace the seal/bearings on these I always use genuine hotpoint kits.. As I always have had similar problems with pattern kits..

Sometimes it helps to fit extra washers to the shaft on the inside of the dryer, as this helps push the drum further on to the front felt bearings. I find if the drum doesn’t quite fit on the felts correctly it will wear the plastic bearing runners away in no time at all..

But as you are more than likely already aware, these machines never seem to go back together, exactly the way they were before dismantling

Check the motor bearings. Seeing a lot of these go noisy at the moment. Often after new belt or bearings due to the increase in pressure on the shaft.

Done one yesterday for the same issue.

You could try a spray if bike chain lube in the bearings can make them sound better. I use bike chain lube as it sprays as a thin oil then goes very stiff like grease.

Hi

Put PTFE or silicon spray on the felt ,I do and helps alot.

Change the belt. 💡

Fascinating thread though, loved the bit about using bike chain oil ………will cooking oil suffice or maybe extra virgin? :clown:

Thanks for the repies folks.

Can’t get back till Mon to re look at the job but made a note of the comments.

Gen kit fitted and one spacer washer fitted – don’t think it is motor bearings as when I twist or lift the front of machine with top off the vibration stops. Suspect it is rear felt seal and hotpoint skimping on felt lubricant.

Ordered up some ptfe spray so will go armed with that and extra washer for shaft. :rolls: Failing that will try belt change.

Thanks

Hi folks

Sorry this has been a bit on-going without a real conclusion.

Been back and lubricated seals with ptfe spray and added extra washer – thought I had cured but cust phoned back and still making same noise. Went back changed belt – thought I had cured again – cust just phoned and making same noise again.

Seems to only make noise on start up from cold and disapears when m/c warms up (or I take apart and put together 😕 ).

I have heard it and it is a rubbing vibrating noise which seems to be drum related and has only apeared since I fitted the new kit to cure the scrapping noise of the drum on the rear of m/c. Don’t think this is motor bearing as doesn’t seem harsh enough also would have thought the new belt would have made it worse as there was quite a difference in belt tension. Have checked for fan noise/vibration but metal fan fitted.

Other than changing all the seals/bearings again (which I don’t think will really achive anything as I would have thought ptfe lub would have sorted) I am at a bit of a loss on this one.

Could try removing the spacer washers altogether but not sure if that will achive anything either.

Open to any more suggestions apart from crap design ones which I already know.

Thanks

I’m in the middle of putting one back together this morning,after having a scraping noise from it yesterday after fitting new bearing kit.
On this one I have noticed at the bottom of the rear panel, there are locating lugs..which had not been located correctly..having now popped these back in to place, it does seem to be going back together more solidly….

I hope all works when I switch on later…

There speaks a true optimist. I never would have thought that a VTD00 would ever be regarded as solid. In reality just one loose screw and the whole friggin’ dryer implodes, metal on metal screeching noises followed by shards of metallic dust covering the floor on which it once stood!

Very true Martin

But this time I have even resorted to pop rivet it back together… Now it does actually feel more solid. LOL

A long shot but have you checked if any of the screws holding the heater cover are catching the drum? I had one where this was the case. Really badly designed dryers and don’t get me started on the the shaft now being fixed to the drum on newer models!

I re-furbed one of these recently and it was vibrating badly when put back together. I was luck enough to have time to investigate over a period of days as it was in my workshop. It turned out to be the front of the drum “sticking” to the nylon fron bearings. I thoroughly cleaned the bearing surface of the drum (front) with wire wool and that seemed to cure it.

Thanks for the replies folks.

Don’t thik it is screws or loose panel but the front bearings seem a posibility.

Presunably you fitted new front bearings when you did a referb? so it was the new bearings giving the problem with a partialy dirty drum lip?

Will give this another try with cleaning the drum lip n remove drum shaft washers. This looked a fairley newish m/c as a teardrop bearing was fitted but no rear drum shaft washer. Would have thought this was a late enough m/c for H/Point to have started fitting the spacer washer – just wondered if they modified the later m/c so no washer was required? Any thoughts?

Think after this I might throw the towel in as its cost me more than enough in repeat calls.

Thanks again folks

10 out of 10 for perseverance Mick! I have noticed that the later ones don’t seem to have a spacer washer fitted? Don’t know how it would help but who knows! Some of these later ones seem to have a triangular brace on the front/side corners, these do seem to go back together better? I guess you remove the drum again, clean everything, silicon spray all friction surfaces and tighten it all up, again! Got to cure it!

Re: H/Point VTD00 T/Drier – vibration after drum shaft kit f

Yes I did fit new front nylon bearings.

The rim of the drum had a light sticky deposit on it, I guess it was fabric conditioner but I don’t really know. Cleaning it with wire woll definitely solveed it though.

I have to say the original bearings pads seem to fit better than pattern parts and for the small difference in cost I think I will stick to originals.
