These are cracking little loco's that can generally be picked up for as little as 20

(http://i1234.photobucket.com/albums/ff414/beeshill/101_0106.jpg)

They can haul quite a few wagons, or coaches, an don't look too bad either.  The only issues in my opinion are the lack of glazing(which can be solved yourself) and the horizontal handrail towards the top of the bodyside is far too thick.  I paid 17 for the Railfreight one :thumbsup:!

Although showing their age these little loco's are stalwarts of the N Gauge British scene and have proved their reliability time and again on many a layout despite the lack of modern features like lighting and model glazing.
For the new starters into N  these 08 shunters are an excellent investment, and if looked after will bring a lifetime of enjoyment for a very low financial outlay (circa 20 second hand)

The liveries produced in the near 30 years of this models production are wide and varied, featuring modern EWS and freightliner colours right back to BR Black and Green. This model is a must for any N Gauger due to their size, ease of use and maintenance and their longevity like the real life beast proves how popular this model is.

The model has been updated and remodelled by Grafar Bach into a new version altogether (reviewed elsewhere in this section) however this model has a longlife yet on the N British scene.

I can forgive a lot of things, but inside frames when it should have outside frames??

Agree with you Poliss on the outside frame locos the detail is far better on the handrails /etc worth paying the extra    :thumbsup:

Although the  older type  body  being  heavier is better for  running i  think.

Hopefully a simple question for someone who already owns one - is this convertible to DCC with the digihat like the current 08?  Otherwise convertible?  Or "experienced modellers only"?

I'm tempted by the green one for sale a couple of topics over... an old / second-hand one is slightly less scary to learn to attach a decoder to than dismantling something I've just paid full whack for.

Thanks,
Tim.

Very easy to fit a Z2 decoder in with plenty of room and yes just pop in a digi hat solder up wires and bingo take about 20 min from start to finish

Digihat, small decoder, much fiddling and it'll probably run like crap anyway.

It's a bit like fitting DCC to old Lima models - you can do it but its basically turd polishing.

Post by: Jonny on March 19, 2012, 04:31:58 PM
I disagree there with that comment
I did this with Dads 08
Fitted a digi hat and Z2 decoder in twenty mins
Put loco on test track programmed in and is now a very nice slow running/shunting engine which it couldn't do before ( using conventional dc controller not pwm)

Have to agree with Jonny, bought one of eBay 6 months ago, fitted a digihat and Digitrax DZ125 decoder and it runs really well, down to a very, very slow crawl when needed.

The only thing it doesn't like is the Peco code 55 double slip in the through station area, but that's not a problem as it does most of its duties shunting in the terminus station.

Converted  around a  dozen  of the older type of 08's with the  inside frames  without any problems with the easy option of the digihat  &   Gerry Spencer  bottom  converting  brush holder.

The only  issues to watch for are the contacts are toucihng the back of the wheels firmly &  the wheels themselves  are clean both contacts &  wheels can  be  contaminated with ingression  of  excess  oil   a  couple  i did  where  stripped down completley to  have all  the oil   removed before reassembly &  conversion,  a very  getnle  wipe with a fibre  glass pencil  on the commutator ( just enough to brighten the commutator) will  freshen  it up   if you go the whole hog &  fit new brushes  then it will   have had a good service.

If your neat with a  decoder &  iron  the TCS M1  decoder will  fit in the cab i  even  fitted  interior lighting to  a few cabs, as i  mentioned above the metal  body of the older model provides better weight for traction &  contact with the rails so  with the older models.

All  the above work  i   describe above isnt   essential on most models the older type convert excellently.   

For a  modern   class  08  in N gauge if it had the  modern  body  detail  with glazing but  made in metal,  complete with  outside frames &  fitted with a  board to take a  6 pin  decoder making it easier to convert ...........  now that would be an ideal loco.  ;D

I've recently become the proud owner of one of these GraFar 08s (via evilbay) and as it's my only loco at present I'd like to give it a clean and wotnot.

Unfortunately, the only service sheet I can find is for the new BachFar version - so, does anyone know where I can find a service sheet for mine.

There are no service sheets for old Farish. It's relatively simple to get the body off (the two screws at one end that flank the main chassis block). This reveal the motor.

If oiling do not get oil on the motor commutator, and it's worth cleaning this and removing any brush carbon from the pole gaps. Lightly lubbricate the gears and axle slots in the chassis block (Mager oil from N-Brass locos is very good for these mechanisms, or Daywat from BR lines which is the same).

HTH,
Alan

Thanks Alan,

I'll get some oil before I start taking things apart :thumbsup:

Call me MR Thicko if you want, but how do you clean carbon residue from the Pole Gaps and how do you clean the commentator?
Thanks in advance

The comm is the part that the bushes run against and will be copper or silver in colour.

Various different ways to clean it, but the main key is to get any previous oil that might have got onto it off (so so common on secondhand Farish, and causes no end of problems). The comm should never have any form of lubricant on it.

For the slots, I use a tip of a scalpel blade to clean out brush carbon that will build up in them (which allows current to flow right round the comm and never get to the coils, hence increasing motor heating).

I've got pictures somewhere of one of the worst I've ever seen before and after, will need to dig them out at some point.

On very old 08s it can also be beneficial to swap the magnet for a new one - the silver magnets seem to lose their strength quite a lot which can lead to slow running, high current consumption and high motor heating.

Cheers,
Alan

sorry to drag this from the deep , but the chassis under the 08 is it the same as the j94 ?

I have one of these in green bought recently from Hattons as one of their bargains so I would guess it is one of the original designs.

My preference is proving to be for locos that run well irrespective of the detail, rather than rivet perfect models that sound coarse when they can finally be persuaded to run at all.

Mine reminds me of the Dean Forest Railways 08 "Gladys" also in green. Pushing new Grampus wagon with ballast it looks and goes a treat. Great purchase. I know that for nearly twice as much I could have had the new retooled version with professionally applied gunge and muck but I wanted a shiny green one like Gladys.

if its got outside frames its the retooled version. If its on a steam loco chassis with all parts of each wheel visible its the old.

Sorry to resurrect an old post, however I recently purchased one of these old Class 08 graham farish diesels for a song, non-runner.
It won't run on the track (as expected), but I did notice a slight movement in the motor, so decided to look further.
I have taken top chassis off and took wheels off and found that the motor runs like a dream. The connecting cog between motor drive worm moves smoothly and connects to motor drive worm well.
Wheels look okay and turn in their motor body recesses easily. When motor drive is held out of the way the wheel cog and connecting cog move together easily.
The problem seems to be the plastic base strip which holds the pickups and is to be screwed onto motor housing.
Whenever I connect that back into place the engine becomes a non-runner, motor gets hot though, so I assume power is getting through. i am assuming that their is some resistance/friction somewhere. Obviously I can't turn the wheels as they are now connected to the motor.
I can't see anything rubbing the wheels except the pickups and where the plastic base sits on the wheel axle recess.
Before I look to replace the base plate and the pickups, any ideas from our esteemed members?

 Just to raise an old observation about Farish loco's,  you need to check the gears. Among my crowd, we have a saying that GF stands for gear failure.
I bought a brand new Cl 37, and had it stored after testing. When the layout was ready I found the diesel was running and jerking, then stopped dead. Problem : the one gear had split.
In the end I used a decent mechanism, and scrapped the (new) GF mechanism.  :thumbsdown:

That's madness. The gears cost 1 and can be changed trivially - scrapping an entire chassis for that is a costly waste.

 It is almost impossible for us in South Africa to get replacement parts. The only place that I have had some   success with is Bob Russell (BR Lines)  ???

Yes - BR lines have the gears...
