Thank you. I have one of these pumps on my 1977 Transit, and it runs nice in the cool of the evening, but blows a little white smoke in the heat of the day. So now I know how to adjust it a little leaner, I am most grateful.

Great tutorial. Solved pretty well my leaking problem and also boosted it a bit

Hello Shane - thank you for your time and instructive video. I might disagree with your analysis of that stopper screw above the Diaphram. I think it is a fuel adjustment at idle and/or a way of correcting AFR with turbo spool-up - as a thought. Have a good day!

Very nice to see an actual pump in the metal so to speak and not drawings on a piece of paper, it makes much more sense now. Being the recent owner of a 200TDi I'm now more confident in giving the old girl slightly more pep. Some thing that comes up on Landy forums, and I'm not sure if it's as critical on other engines is exhaust temp, they recommend never touching the maximum fuel screw on the back of the case unless you have an exhaust temp gauge fitted. Seems the Landys aluminium heads loosen valve seat inserts if the exhaust gets too hot. Probably just a Land Rover design feature :-) Cheers.

@Tractorkinguk

I have never heard of the valve seats coming away, you may get that problem when running too much boost pressure as that would raise the temp a lot, glad the video was of help to you

Helpful video thanks. I was looking for the next video where you go inside. I'm trying to figure out what the lever on the side does. Mine was loose when I did the throttle shaft bush. I think the spindle is in a different position on the shaft. As it was so loose. I wanted to see and hear what it all does. Many thanks.

Nice video thanks

Tyvm i have one of these pumps on my 82 isuzu i mark diesel

i actually have on of those pumps laying around as a spare. same parts number as well

But honestly please continue this series with a breakdown video of this pump

Thanks! This was really helpful! What happens if you adjust that top nut (under the cap)?

@Tractorkinguk

3 жыл бұрын

Thanks for the reply and I’m glad the video helped. The adjustment under the cap if tightened inwards this reduces the amount that the diaphragm can return when no turbo boost is made, this then allows the pump to deliver slightly higher fueling when no boost is been made which is really no advantage to power increases. Please share the video if possible as I’m trying to build a greater audience and if there’s any suggestions of videos people would like, if I can do them I will try my best to post one

Really informative video, well explained, thank you. Do you have any advice on how to test and if necessary, replacing the diaphragm. Is it simply removing the retaining nut and washers to replace the diaphragm, or is there some kind of alignment necessary? Thanks again

@Tractorkinguk

Replacing the diaphragm is simple like you said just undo it and replace, no alignment etc, as for testing the diaphragm this would be quite difficult so if in doubt just replace it

I live in a. NON Emissions state. So I'd turn the co..AR half and the diagram post also half, On the non turbo V4 pump will simply adding 2 washers on the spring advance give it more power? I rebuilt my V4 pump on my peugeot and it has new injector nozzels also with no added shims. I have a donar pump and I'm considering adding its 2 washers as my boost ring upgrade will it work.

If you wind in the fuel screw much more than half a turn you can break the fuel controle mechanism spring and the pump will stop fuelling.

Thanks a lot for this video. I have a 12mm rotor pump, and ive played with the enrichment screw. The car is currently not running well, and exactly what you described happened when i went too far. Rev hanging, and slow to return to idle. However there is little smoke while revving, and a decent amount of smoke at idle. It feels underpowered and sluggish. I have yet to turn the star wheel, but i will try it soon. Any advice for the current synptoms im having? Thank you!

I've adjusted fuel & boost spring, then did the governor mod. It won't rev higher than ~1,500 then it'll choke and I get white smoke until it dies. Tried 1.54 & 1.45 timing on the gauge without much difference. It gets worse when warm and won't restart.

@Tractorkinguk

Oh good to hear you have sorted it out, you may have turned it anti clockwise previously which loads the spring up more and then requires greater amount of boost before extra fuel is delivered, lowering the wheel reduces the tension and allows extra fuel at lower boost levels. Thanks for the comments and happy you gained something from the video

Great ,very clest

So I have a question, I have a 83 gmc s15 wich has a 2.2 isusu in it. I've added a turbo and while turning the screw on the back I went as far as I could before I couldn't adjust my idle down anymore. After doing that I thought it would be a good idea to take the arm off the throttle shaft and adjust it back one notch for a little extra idle lowering ability. Now I've realized that won't work and I can't get the same power (fuel) I was before because it either revs up way to much or idles to low. When I get it perfect I have no exta power it's worse then stock. Idk if I messed something up while moving the throttle arm or what. Any advice helps, thanks.

@Tractorkinguk

What I would try first would be to back off the max fuel adjustment and set up your throttle linkage again as the adjustment screw affects the tension on the government springs attached to throttle control, it’s also possible that the spring has got jammed on underside of the throttle, try back off screw first and reset throttle if that don’t work I will put you a video on of how to remove the top and what’s inside

Will a pump from a 94 300tdi fit a 200tdi

This might be a noob question but isnt changing to a bigger plunger just the same as increasing fuel supply on the max power fuel screw? For exemple, a 10mm with increased fuel screw would deliver the same fuel as 11mm with stock fuel screw no? Thanks

Greate video! Unfortunatelly I have problem with my pump. There is custom boost pin, I have cranked spring tension about 4 clics (like 1/8 turn) and increased fuel ratio with 1/4 turn. After starting engine the pump is leaking a lot, the leak looks like from middle section around speed mechanism. Anny idea whats wrong? Also I can't lower my revs anny more, the linkage is stopping me from doing it. Appreciate anny help!

@Tractorkinguk

2 жыл бұрын

As for the revs you will have to obviously make some adjustments to your linkage to do this, fuel leaks are common on the throttle spindle shaft and the bush wears out also, both the bush and seal are available on eBay but this requires removal of the top lid and some springs, if your not confident don’t try do it yourself

2 жыл бұрын

Alright, I have replaced throttle spindle shaft oring witch main body seal, that was the cause of leaking issue. When putting it back together I have also rotated throttle lever two notches and that helped to get lower idle. But there is new issue, it can be heard that engine work is more clanky, more metallic with a very snappy and sensitive reaction to throttle. There is also a bit of white smoke at startup and some revving. My question and theory here is: Is it possible that resealing pump restored factory performance and changed engine timing? The pump was regulated by previous owner probably "by ears" with leaking sympthoms ( i suppose) what caused setting more advanced timing to get normal work due to lower efficiency?

@Tractorkinguk

2 жыл бұрын

Firstly taking the top off and putting it back on can’t adjust timing, but there’s one thing to check that you may have removed that will effect running. If you removed inlet and return banjo fittings check that the return line has the bolt with smaller hole in it, this affects case pressure of the pump if wrong way round

hi, I see that you attached the pump from the car, so I got the idea to do it myself, but the direction of the ignition bothers me, the crankshaft and the pump rotate in the same direction in the Ursus, and in mine the pump is in the opposite direction from the crankshaft, the question is whether it can be done to combine, and the holes on the pump where the screws go all graze. Thank you for your reply.
