[wibbly wobbly speedo]

Big thanks to CwazyWabbit for doing my speedo mileage correction, was done in super fast time.

Cheers Stuart.

[wibbly wobbly speedo]

Got the temp gauge to work was a broken wire on the speedo loom and also fitted the speedo speed transducer and that works too

Just need to get it over to CwazyWabbit for him to correct the mileage

Thanks for all your help

Cheers Stuart.

You did go for a drive I take it? my 200tdi barely warms up when sat running for 30+ mins.

Yeah took for a drive, I've got it through the speedo and it's not working, going to try the resistor way.

[wibbly wobbly speedo]

Are these type of resistors ok http://www.maplin.co.uk/610-piece-e12-1-4w-resistor-starter-pack-2163

Cheers Stuart.

Pin 9 does not appear to have a direct path to pin 5 having checked the traces on the other side of the board. Pin 9 is connected to one leg of a transistor. The resistance I measured appears to have been tracking via resistors that are commoned to 0V rail. This means the resistance I quoted is of no use to you, sorry

It is hard to follow the traces on the reverse of the board as it doesn't look to be easily removable due to the needle being glued on to the stepper motor shaft..... and I don't fancy damaging the speedo.

Ok, thanks for your help

Cheers Stuart.

I agree just looked at the picture of the speedo board in this post and you can see pins 3 and 5 linked by a couple of components, pin 9 must be linked on the other side of the board but my point is there is definitely more than just a simple resistor involved as other pins are also involved in the circuitry.

Shall I open a speedo up to check?

If you don't mind opening one up, Cheers

[wibbly wobbly speedo]

Resistance as measured with a multimeter between pins 5 and 9 on plug B on the back of the speedo is 13.39Kohms if that helps you.

So does that mean I need a 14k resistor.

[wibbly wobbly speedo]

Temperature gauge signal runs from the sender, through the speedo head, and then to the gauge.

It is possible to trim out the difference using a resistor as well, but I can't recall the value off the top of my head. It's in this thread somewhere I know!

There is some resistor values in this thread, but I'm sure they where for a 200tdi temp sender.

[wibbly wobbly speedo]

Just been doing some searching about this temp gauge, I am right in thinking if I connect the gauge direct to the sender and not through the speedo it will over read and go into the red at normal operating temps.

So do I just need to fit a resistor inline between the sender and gauge, if so does any body know what resistor I'll need with a 300tdi green temp sender fitted.

Thanks Stuart.

good man, :i-m_so_happy:

Cheers for the link The X-Brake came today, only ordered it yeterday

Fitted the genuine temp sender tonight and still doesn't work When I turn the ignition on is moves to the blue part of the dial and stays there until I switch the it off.

If the ROW part of the speedo is broke can the td5 temp gauge be used without going through the speedo.

Any ideas guys.

Stuart.

Just to update any interested parties , i have fitted the Puma 90 TDCI REAR propshaft to my 300tdi 90 today, and the vibration has vanished. Would highly recommend this to anyone who has suffered minor vibration like myself.

Rob

Glad you got it sorted.

[wibbly wobbly speedo]

you know you want one & it makes sense

Ordered one yesterday

Stuart.

[wibbly wobbly speedo]

Thanks for the replies, if I'm going to have to take the brake drum off, I might as well order a X-Brake

Cheers Stuart.

[wibbly wobbly speedo]

Might be a temp sender fault, only way is try another known good one or a brand new genuine LR part, speed sensor just needs fitting very carefully, if you can see how the drive gear shaft is orientated then align the sensor to match, or partly extract the gear & housing then slide the sensor into the shaft & push back into transfer box hole & bolt up.

Have ordered a genuine temp sender and another speed sensor, it's extremely tight for room fitting the speed sensor with the handbrake drum and cable still fitted.

Will see if I can align it up better next time.

Cheers Stuart.

Hi,

Thanks for all the info in this thread, made it a lot easier to do.

Got a couple of problems.

1 - The temp gauge doesnt work, it moves about 5mm when the ignition is on but thats all, i've done the ROW wiring and fitted a green AMR1425 sender. I've tested the gauge by connecting it to the fuel gauge wiring and its works.

The only thing I can think of is the green sender wasn't an oem part, it was ALLMAKES.

2 - The speedo didn't work, so took the transducer out and found it had snapped the plastic square drive pin off the end of the transducer. Was it just bad luck or is there any way of telling if the drive pin is located properly as the transducer is spring loaded. I've ordered a new one but don't want to snap this one.

Cheers Stuart.

[Britpart OEM????]

Nope. Ive got the larger TD5 wheelboxes to suit.

[Britpart OEM????]

Since the original question has been answered:

That would depend on how many teeth were on the wheel at the wiper end too so to mark the gear seems odd. 140 teeth seems more likely.

Chris

Hi. 140 is the degrees of sweep of the wipers. On my 300tdi it's got a 115 deg, the 140 deg was fitted from 2002 when they moved the wiper motor higher up the bulkhead and changed the size of the wiper wheelbox for a larger size cog with 40 teeth instead of 32.

If you've got the smaller size wheelbox's you might find the drivers side wiper blade sweeps off the screen.

[Puma 90 diff]

Yes it's a straight swap

Thanks for the info.

Stuart.

[Puma 90 diff]

Hi.

My rear diff needs replacing on my 1999 300Tdi 90, will a diff from a 2011 puma 90 fit in my 300 rear axle.

The puma diff is not a p38 type.

Cheers Stuart.

[tdci prop on 300tdi ?]

Yep, front and rear on a 90 will fit. The yokes seem slightly wider and bigger than the old type props.

Stuart.

[tdci prop on 300tdi ?]

Hi, Tdci (puma) 90 will fit, i've got them on mine, it's a straight swap. 110 not sure, front will but the back might not because of the short diff nose of the p38 diff.

Stuart.
