200tdi vacuum pump delete

Can I remove the vacuum pump, leave the shaft and seal/bolt a plate to delete the pump?

Or... is there anything I'm overlooking here such as oil pressure.... or ?

Is it different from the 300tdi's cam lobe driven one?

you will to support the top of the shaft with a plain bearing machined into the blanking plate, if you must why not take the vanes out and blank off the hole?

Motor is in a series 1 with no power breaks ( I did go wildwood dual circuit though)... so no vacuum needed.

It seems like just removing the vanes is the simplest... I just wanted one less moving part and less chance of sucking somethign nasty in to my block.... but it is seeming like a PITA to delete it.

Can I remove the whole shaft?

Jut run the hose to the valve cover or such. It discharges the air to the cam gallery, If you read the description, you would want to be careful removing the vanes as oil is pumped in behind them.

My understanding is that if it is allowed to suck freely it can cause excess pressure in the block.

Would removing the vanes cause any problem though?

Reading the description routing from the rocker cover wouldn't cause overpressure, it would suck from the engine internals and return to the engine internals. You might want to put some sort of restriction so that it's not pumping at full whack all the time.
Reading the description I don't think removing the vanes would be a good idea as it mentions checking an o ring in case of low oil pressure.
Just my take on it.

What about fitting a remote servo?
You'd get a useful brake up-grade.

Steve- I have no input on the subject, sorry- but interested to find the solution...
However, I could use the pump should you be able to sell it when you are done.

Mike- I agree that routing to the rocker cover would cause no harm.
I did look into a remote booster, but they are expensive for dual circuit. Plus im trying to keep this truck as simple as possible. I kind of enjoy the non boosted brakes on my 911... so we'll see if they are as fun on a S1.

I really like to get rid of it but I guess I'll just revisit this later and if I do I'll let you know rover trader.

look up brake servo vacuum pump bulletin, RR3950M

Tells of occurring low oil pressure if "O" ring is damaged. find your self a 200tdi engine rebuild manual.

this "O" is fitted into the vac pump.

You are on your own removing the Pp

wilwood

LOL I just got my series II 200tdi project going down the street after a year. I couldn't figure why my new engine was blowing so much oil past the oil fill cap on the rocker cover. After messing around with it for a couple days I figured out it was that damn pump sucking air inside the engine. I had a breather on it so took that off and plugged it up and she's not leaking now. Had me worried for a couple days as it's a newly rebuilt engine. Did you change to wilwood pedals as well? I'm thinking about using their pedal assemblies, if it will make more leg room. i'm tired of raising my knees to the roof to get on top of the pedals. I used the defender throttle but I also want to change that if I can get something in a better position and still have clearance for full throttle. I had to tweak it to mount to the bulkhead and after driving it for a week I'm not happy with it's position.

This is on a series 1 so it has floor pedals. But I did use a wilwood dual brake master.
I just bled it and it gets nice firm pedal... but no road test yet
