Hbv problem ??
« on: 01 August 2011, 08:47:42 »

As above

Yesterday, I plumbed in the reducer for my lpg kit.
It is now "inline" from the back of the coolant bridge .............. too the reducer ............... too the hbv.

Right, I have no problems with heating / cooling but it seems that the only way I can get the reducer hot is to put the heater controls to hot.
Its a pre facelift.

Looking at the guides ( first for me I know  ;D ;D ), it looks like my hbv is mounted upside down to the one in the picture.
The pipework too the hbv looks to have been moved around / cut up  :-/

Is they a picture that shows the hbv and which pipe comes from where ?

Hope this makes sense  ;D

Right, I think the first thing I need to do is remove the pipes and turn the bugger round the right way if the pipes reach  ;D ;D
I'll report back when I can work out were the pipe are going  :y

I Know that the hbv is basicly a vacume operated valve for the water flow but is there a non return valve in the hbv ?

Now sorted  :y

Whilst I think about it... When it comes to plugging the laptop into the LPG, you'll have to have a little play with the reducer (coolant) temp sensor setting to get the one which gives the closest reading to that displayed on the dash

Question .............. What is the minimum adviseable water temp for the gas to cut in ?

Can anybody think of anymore pitfalls i'm liable to fall into tomorrow when I plug in the laptop

I tend to set them all up to 25 Degrees or 20 seconds... If you leave it at the default 3s then when the vap is warm enough it will switch over in 3 seconds and idle grumpily due to the petrol ECU enriching it (which LPG doesn't need)  ::) There is a temperature adjustment feature on the LPG mapping side which I intend to have a play with at some point ::)

Mind you... There's also a timing processor available which will adjust the timing appropriately for LPG (instead of the compromise we currently use) which is supposed to improve the LPG economy... I'm hoping to take a trip down to the supplier to try one out (they look a little complex to set up) and see if it's actually worth it ;)

Only other pitfall is that the KME reducer is, in our experience, more complex to get mapped perfectly than the previous one so I'll be expecting a call ::) ;D

Take the nut off, slide onto polyflex, push fitting into polyflex (right up so the polyflex touches the flat of the fitting), do up nut :y

Other end is normal compression type fitting :y

I couldn't get the nut or olive over the end of the pipe so I had scrapped back the gray insulation and slid it over the white plastic centre then stuffed it in the hole and atacked it with my spanner  :-[

I take it that the brass nut and olive HAS to go over the full pipe  ::)
Are these olives 8mm ?
If so, i'll get some more  ::)

If so, any tips on how to get the nut and olive over the pipe ?


cheers  :-[

No olive on the bit that goes onto the polyflex pipe, only on the metal end ;) I'll have a look for a photp.

The nut is tight but will go but the pipe cannot be reduced in diameter otherwise it won't seal (as you found out)

Olive's are 8mm :y

Yeh I understand the fitting that goes onto the tank outlet ( push pipe over the crome bit to the hilt and nip up the nut )  Confident that I will have no problems with that one  :y

Its the conection on the back of the pipe for the filler / tank inlet / reducer that leaked like break  :(
I just couldn't get the brass nut and olive over the end of the poly flex  :'(
Hence me scrapping back the gray insulation and slideing the olive over the end of the white pvc  :-[

I wouldn't mind, i've been using compesion fittings on plumbing ( diy ) for years  :-[

There's no olive to go on polyflex pipe... The olives only go on the metal part of the ends ;)

All polyflex ends fit the same way... Remove brass nut, slide onto pipe (tight fit), push like break to get the flared end of it inside the polyflex (right up to the flat), tighten nut back up (being careful not to twist the pipe and cause a kink)

The polyflex pipe isn't actually 8mm... It's an imperial size close to it so a 8mm olive is never, ever going to fit ;)

So the olives that came with the filler / inlet valve / inlet to the filter / reducer are not used  :-/ :-[      Olives are only used when you use copper pipe ?
