servo

[stuupnorth]

hi all
any pictures of the correct orientation of the brakes servo set-up?
just to double check
as i have fitted it the same way i have seen some done but i am sure i have now read
that it should be fitted in a different way??
sorry for dodgy pic

Well it's certainly the 180 degree switch from Basil's....

You're looks to be very cramped; I'm also fascinated as to how your Coil seems to be fitted...?

[stuupnorth]

cheers for that i had heard/seen that the servo should be 'twisted' slightly so the
white vent? is to the side??

Hi as for the coil it was fitted there before i decide to fit a servo!
i made up the bracket once i changed from dynamo to alternator

I've seen some photos online that look as though the servo is completely upside down, let along 'twisted slightly' but I've no idea why that is. Basil cam fitted with his servo when I brought him.

I guess someone will be along soon to explain any logic behind it.

(and thanks for explaining about the Coil. )

I believe you have it the right way up with the fluid inlet at the lowest point, the only criteria I have seen is that the outlet should be angled up so any air gets easily bled out, it doesen't matter which way they point in the vehiçle though.

hi
i used the bracket supplied with servo which makes the 'nose' slightly higher than the rear ?

The nose should be pointing slightly upwards, the "air-valve" pointed slightly downwards , as otherwise air would be trapped in both..

ok mate many thanks for the info
i had a strange feeling that was the case so i have ordered a couple of new brake pipes
so i can rotate the servo
cheers

Seems to me that I need to reposition Basil's Servo.

Having read the comments, I did some research and found this instruction leaflet.
https://www.skandix.de/en/documents/ins ... s/3000118/

With the aid of the mounting brackets and fixings provided in the kit install the servo unit with the hydraulic slave cylinder outlet port inclined upwards between 25° and 45° from the horizontal plane. (See, Fig.2). The air control valve should be situated at least 30° below the centre line to assist when bleeding the hydraulic system. (See Fig.3).

Some clarification sought from anyone with a Servo fitted.

On closer examination of Basil's installation, the main mounting plate only has 2 holes, so unless drilling new holes in the plate, I'm faced with a complete 180 deg flip.
Has anyone got a servo fitted with the Air Valve completely on the lower side, rather than at the 30 degree angle. The instructions I found do say

situated at least 30° below the centre line

so I guess that 90 degrees fits that description.
Does it matter?

Your thoughts please.
Thanks.

Leaked hydraulic fluid in the vacuum chamber might be a problem if the take-off is at the lowest point?

I think that might be the least of your worries if the hydraulics were leaking into the main vacuum chamber.
I actually found one video about fitting them where the guy misunderstands the 'at least 30 deg below the Centre Line' as being 'no more than 30 deg from the bottom'....

I think I'll go for the 180 deg flip on the mounting plate, and possibly remove the in-line NRV too, since the instruction leaflet says that's only a requirement for High Performance Vehicles (there is already a NRV in the system, as detailed in the instructions).

Open to any other suggestions/comments about the mounting with the white bit facing down....

" On closer examination of Basil's installation, the main mounting plate only has 2 holes, so unless drilling new holes in the plate, I'm faced with a complete 180 deg flip. "

No need, just loosen the vacuum chamber " belt" and rotate the main body to your requirement...

You may need to replace/reshape the input pipe but the output pipe will be OK.

Hi John
I missed your response back in May.
Have only just seen this; thanks for the suggestion.
Thinking about it though, the short hose between the 2 sections wouldn't let that happen.
