I wasn't sure to add this here or in TDI -but I have a pump that will be going onto a 1Z/AHU tdi and I wanted to change the aneroid seal and the shaft seal. When I pulled the aneroid off, I wasn't too careful and there is a lever on the front of the pump (if it were installed on engine) that is connected to the throttle with a couple small, light springs and small rod.
Inside the pump, does this go behind the control lever inside the pump? I'm assuming it does so when you start moving the throttle the little springs move the control lever forward before the governor springs & lever take over?
The lever on the outside of the pump kind of looks like a late model 1.6TD idle lever (back of the 1.6 td pump) only this is on the front of the rover pump.
thanks for any help.

Little black lever on bottom of above picture-I just want to confirm this goes behind the control lever inside the pump. The governor lever isn't the same as this picture, but the bottom lever is.
thanks

I am thinking it stays like it is in the picture.. It is a fuel shutoff for atuo tranny cars in case of emergency.
It needs to help push the control collar towards the pumps snout, so that looks right.
Be more careful next time ;) This is not a demolition site! haha

Thanks, I wasn't sure how it was when I took it apart, but this seems logical.

you know dumb ***.. how many times you gotta be told it is NOT a fuel cut off...............

to the op.. talk to libby.... as im sure ill be banned once more........
log in.. read one post.. gotta correct stupid...........

I do not appreciate the barbaric name calling Christopher. Most certainly a fuel shut-off in the picture posted. If the op's pump looks like the one pictured. Spring loaded to stay up out of the way, swings down to push the internal throttle lever away from the governor opening the spill ports in the plunger for ANY rpm, resulting in engine shut-down.

The cover pictured doesn't look like my LR pump. My LR pump had a compression governor spring capsule instead of the extension spring as pictured. That looks more like the 4BTA style.
Anyway... often that lever on the side of the pump is a mechanical shutoff but it isn't on the LR pump, tho. I have not found that it affects fueling at any time the engine is running. Best guess I've heard was suggested by Vanbcguy... maybe it reduces the puff of smoke at startup by limiting the control lever movement when the engine is off.
-
Do they look like the one pictured? With the lid off does the internal lever have noticeable movement that could swing far enough to be a shut-off?
If the lever does not affect fueling while running (meaning it is not touching the internal throttle lever) how would it touch it to limit start-up fueling?? Just curious.
-
On the rover pump that extra lever does not have enough swing to be a shutoff. In fact with my engine running I've moved that to the off position and it doesn't even decrease idle...
The Rover pump has an interesting link between that lower lever and the accelerator lever. Any time the accelerator lever is moved off idle it pulls that lever away from the position where it would limit fuel. Because of this, any time you are above idle, the lever does not have any affect on fueling. Without that lever, when the engine is shut off, the flyweights relax and allow the control collar to move to a greater-than-idle fueling position until the engine starts running and the flyweights push the control collar back away from higher fueling and maintain idle. With that lever in place it could limit how far the control collar could move when the engine is off and the flyweights are pushing it back from higher fueling. As I said, that's really the most reasonable explanation I've heard for that lever on the rover pumps.

Interesting. Yes, starting is full fuel enrichment. I guess we need a video of a Land Rover starting to see if it limits the start puff of smoke.. ?l lol

then you should stick to things you can give correct info on....
1st post ive looked at in whiole and i have to fix your mis information????????? really!!!!!!
subject... rover 300 pump...
he states lever hooked up to throttle lever with springs and stuff...
those things = crsmp5... *** he ***en asked me what the *** it is 3 years ago.. we decided then if hooked to throttle lever canot be fuel shut off... but no you spout *** of stupid... yes your the reaon i no longer read posts here.. sick of reading repeate of stupidy you type...
next time you should say no fn clue.. ask libby...

No banning, right now it is just a conversation. Keep the conversation milder please. The asterisks are blocking the words but it can be inferred to what is being said and that could be something bad, if you would please edit out the asterisk words, you can show what is incorrect or a lack of knowledge without using profanity, if that is what you were using. Please remember that children can log on and ask what it all is about. The only thing ban worthy is in very small print, but I will leave that up to Red Rotors.
I prefer to leave everything relevant up and keep the flow of the board going. Sometimes things have to be taken out. or locked. Please help me to keep from having to do such things.

Interesting. Yes, starting is full fuel enrichment.
I do not believe that starting is 'full enrichment'. It is above where the control collar would be at typical idle, but there is not enough range of motion in the idle spring to move the control collar to the 'full fuel' position. If you remove the accelerator lever return springs and the accelerator shaft o-ring and then put it back together without the return spring and o-ring and then operate the accelerator lever by hand, you can feel when the control collar stops moving and the idle spring begins compressing and then where the main spring comes into effect. With my '79 rabbit, it takes a noticeably less cranking to start if I hold the accelerator depressed a little.
-
Riiiiight, and that was a much less stupid post CRSMP5? If one person causes you to leave this forum than so be it, its a free board. Sort-of.
Is that really ban worthy? Possibly, there were no repercussions that I could see.
I am pretty sure I read somewhere that the relaxed flyweights move the collar past where it would be for WOT, but I could be wrong.. I was wrong before :P.

I assume that to be the only part of your post directed to me...
I think it really depends on the relaxed height of the idle spring and the position of the max fuel screw.

The outside of this lever is shown on this picture, but the total movement of the lever might be 1/16-1/8" which moves that lever inside a very small amount.

The little two spring unit (1) moves the lever it's connected to (2) very little 1/16-1/8". the light springs take up the rest of the movement of the throttle.
So if it is to move the control lever inside the pump at startup/or when its off - the lever shown in the first picture is backwards, should the tip not be towards the back/ where the injector line connect; and not the snout or shaft side/ belt side of the pump?
Sorry for the problem, I should have taken pictures before pulling the top off.
-
That first pic looks right. It limits the max so the lever should be toward the snout in the at-rest position and move toward the injection lines to limit the fueling.
