Hi guys ,my freind has been and bought himself a prochem cheyenne apparently for a good price so couldnt turn it down ,his words not mine.
Well this machine seems to be sparking from the motors when on and rang me to ask what I thought .
Well I said perhaps it is the vac motors but to be honest I have not got a clue ( just a mere carpet fitter )so thought I would ask the fonts of knowledge which is you guys .And if it is the motors any ideas best place to purchase them .Afraid I have not heard of a cheyenne ,thought it was some American state .Hope he has not bought a dud as he is struggling at mo .

Its a Prochem machine.

Fitted with 5.7" 3 stage Lamb vac motors (I think) I used to have one and it was a great machine.

I am pretty sure it was 3 stage motors and the Commanche had twin 2 stage vacs.

[richie]

Yes it is a Prochem machine.  As for which vacs are in it....it should say on the current vacs what they are.  Prochem made a few different Cheyenne machines with different specs.  The basic one had Dual 2-stage vacuums in it. The CHEYENNE 3 had Dual 3-stage vacuums in it.

Would you say then guys the fact it is sparking ,then it does look like the vac motors are gone .Any ideas where to buy and best price if it is .Thanks in advance

[richie]

You can get the vac motors from ebay or www.wcsuk.com

[tony bish]

So would you say because it is sparking that it is a good chance it is the vac motors guys

[robert meldrum]

The Cheyenne is still a current model in the USA....I have one and it,s as good a machine as the Ninja. A good point is that it's set up for a 2 inch vacuum as standard.

Thanks Robert ,so it is a good machine then ,he is a bit worried about the fact it is sparking though and we can only assume it is the vac motors but we are not sure.So the fact it is set up for a 2 inch vacuum does that mean it is pretty standard to all other machines then mate .Do you use your machine as your main one then Robert .If it is both the vac motors going then I would assume that is a fair bit of money then .Thanks guys

Im gonna sound like i sell these or something lol  ... but two of these should be good value for your friends machine ... from a known source , have air seal  etc ..

Is it a parallel or series machine ?  not sure if 2" machine fittings will matter a whole lot anyway , especially in a series machine , as 1 1/2" hose  is suppose to be good for 200cfm , which is the max u will get with two standard 5.7's in parallel.
You would definitely see a benefit with three motors or some of the newer high airflow motors . 

[tony bish]

They look like the kiddies John .As mentioned we dont know a lot about these machines in fact I dont know didly squat ,so are we right in assuming they should not be sparking when turned on ? the fact that when we put our hand over the machine suction inlet there is no suction at all so would also assume thats a bloody good indicator I would have thought ,but hey what do we know .Are they hard to fit yourself mate .Obviously he doesnt want to spend a lot on machine .   

[richie]

Sometimes on startup vac motors will give a small spark but this should then go.  If when you have turned the vacs on but have no suction i would think that the hose leading to the waste tank is maybe disconnected somewhere.  Open up the machine, follow the hose from the motors to the vac tank.  Check for splits in the hose or if disconnected.  Generally speaking vac motors are pretty easy to fit.  Some machines can be a little fiddley but no reason why you or your friend cant fit yourself.

[tony bish]

Hi Richie ,thanks for reply ,no sparking does not go out when running machine,and we have not got hoses connected regarding suction ,just putting hand over inlet where hose would go and doesnt seem to be any suction at all .

[tony bish]

Sorry Richie just read your post properly regarding hoses .

[Kinver_Clean]

Be careful you have enough height available- some of the cheaper vacs are longer in the vac section than real Lamg vacs and wont fit all machines.

 The European made Ametek ( the £55 one in the ebay link above )  is the same length as the lamb (Mexican plant ) Ametek ...

205mm from bottom to top , not including the vac tube which is almost 20mm .

[Jamie Pearson]

They hang on the underside of the machine with the inlet of one attached to the exhaust of the other.

Thanks guys appreciate comments,got in touch with website chap John and he seemed to think it may just need the brushes changing .Are these straight forward to do . Thanks again

[Kinver_Clean]
