Diesel speed...

That's about what we found when we fitted the 2.5 from a sherpa in a series3 to replace the 1 1.4 diesel. I never did get around to fiddling the pump before it was sold.

AJH

I'm glad you got him fixed!. Was it just the starter then?

I can now get past 70 (on the GPS) on the dual carriage way with mine without too much difficulty, at which point the LWB speedo reads pretty much exactly right. Mines a SWB with Trac Edge's on and an overdrive (which i think adds about 10-15mph top speed).

I got the speedo up to 85 (going downhill!) on tuesday at which point it packed up due to the shock!

I can get up hills without too much difficulty, generally in 3rd or

3rd overdrive. I think the only time i had to go at 25 was when i had the tub filled to the brim with wet soil, and was pulling a trailer to match,..

Before i rebuilt my engine (which made a big difference) i had the injection pump reconned and replaced the injectors, and that made a fair difference. It was smoother and less smokey and a bit faster and nippier, and generally nicer to drive. Injectors should be about a tenner each exchange and the injector recon and set up was about £80. That might help your speed issues..

I also have the K&N on mine. You could try sticking one of them on to see if it helps?. For the first week or so after i clean my K&N i can hear it sucking from inside the cab so it definately pulls a lot of air through there, so in my eyes is worth it!

Does your engine breathe a lot at the moment? (out of the oil breather that goes in the rocker)

By the way Tim, are you still considering converting your landy to a station wagon?. I've just sent you an email - Have just acquired, and am now breaking, a safari station wagon, and all the bits you need are surplus to requirements and seem in good nick..

Sounds like the sort of performance I used to get from my old 2 1/4 petrol in Percy.....

And...a V8 and SD1 Auto gearbox along with an Ashcroft transferbox to auto box conversion would go in a treat and save you having to stir the gearbox.

That was my plan till some fool sold me a Whole Jaguar attached to the gearbox I needed. :-)

Would be fat simpler doing the SD1 version.. so much so Ashcrofts even state it can be done...so in effect it must be a doddle! :-) Or youcan keep on flogging that diesel.... choices choices :-)

The conversion kit was around £350 or so,,,,, then a scrap SD1 should see the rest of the required bits.... then an exhuast (easy with the V8) and prop shafts... so are you up for it? GOAWRN YOU KNOW YOUR INSPIRED ;-)

Get it sorted and you can say, "What Hill?" "What Trailer?" "What Police officer?"

First, GPS is usually quite good for a speed check, though it can glitch. Sounds like the speedo is calibrated for larger tyres or a different diff ratio, and that ought to be sorted out.

Back when I ran a 2.25 diesel I was getting more speed out of an SWB than that, but not a great deal more. It's the hill-climb speed that suggests engine problems, rather than any limit on revs (the speedo reading suggests you can get the revs for 60mph).

Any sign of smoke?

The injectors are certainly worth checking, but if you're not getting any smoke it's a bit more likely that the injector pump is set low

AFAIK axles / diffs are as standard. The tyres are standard LWB size (750 x 16 or 235/85, not sure which).

It will rev much higher in 1st and 2nd than it is able to do in top, and on the downhill 50+ doesn't sound to be putting any strain on the engine rev-wise.

All pretty clean really, though I haven't hung out of the window to check whilst flogging it uphill.

That sounds like a possibility, and a fairly easy fix. Do I just 'turn it up' myself until it smokes and then back off, or should I book an hour with an expert?

Could be a fault on the speedo... Have you checked distance readings? If they match between GPS and speedo, it's a fault in the speedo mechanism. If distance readings as wrong in the same way as speed, you've got the wrong speedo.

Injector pumps are something I have never tried fiddling with.

I'm not too bothered about the speedo inaccuracy, I'm more concerned that it doesn't go very quick!

The bloke in my local diesel place reckons that you shouldnt mess with the injector pump yourself, and got all upset because when i took mine in to be done because we had previously messed with it to increase the tickover speed. They put little covers over all the screws that are tied on with funny little metal ties when they set it up.

I'm still going to mess with them if i have to, but it does seem to be fine now. The reason i had to initially mess with mine was apparently because a valve or gasket or something in the pump was buggered (so they said).

From what i gather, when you set-up an injector pump all they do is set the fueling rates correctly for different RPM's (using the factory specifications unless otherwise instructed i presume)

If i were you i'd go for it. Have a play with the screws. Mark them first and remember how many turns you have done, and do it cautiously. Worst case should be that you bugger the pumps settings up and make it run even worse - at which point you take it to the specialists and have it set up and overhauled properly...

On or around Wed, 07 Jan 2004 00:01:46 +0000, Tom Woods enlightened us thusly:

that's cos they want to charge you for fixing it. The main trick is knowing which adjuster does what. On some pumps, for example, to adjust the fuelling rate you have to take out a plug in the side of it, turn it to just the right position, and insert a 4mm allen key into the middle.

However, the most simple test is easy-peasy. Establish some means of counting revs, (you can use a strobe attached to a petrol engine for this), warm the diesel up thoroughly and see what it's maximum no-load speed is.

if it's low, then the pump can stand more opening - there 's a maximum speed stop which stops the "throttle" lever on the pump (i.e. the one that the throttle pedal attaches to) and this can be adjusted to give more or less maximum speed. Typical figures for pre-TDi are about 4250 I think, or maybe

4500, but check in the book.

I assumed that would be the case! :)

How would i go about putting a rev counter onto my diesel engine if i wanted to? With the injection being all mechanical i take it that its not a straight forward thing to do?

Sorry I can't remember what engine it is. On my 300Tdi there is a connection on the alternator (maybe on all TDi's) that you can hook a rev counter upto.

I bought a kit from

for 45 UKP. It is a VDO tacho that is the same size as the other gauges on my dash so will fit in nicely.

Must get round to fitting it!
