MG MGB Technical - in-active Servo

Hi, I have an MGb GT 1978 1800cc model. My servo is inactive and I have done the usual checks to establish there is a loss of vacuum. I noticed that the connection to the unit is loose to the extent that it can be moved quite easily by rotating the vacumm hose clipped to it . Any advice please on either replacing the servo connection or do I need to strip the unit down.

Thanks

Hi si, see my thread on bendix servo problem - had the same problem. Fixed it by buying a servo kit. Now works very well. The difference was very astounding.

Servos are relatively simple mechano-hydralic/pneumatic actuators!But if there is a break in the vacuum supply they won't work. Also if there is an internal hydrolic leak past the seals they will be inefficient. But as Moss has said, easy to buy a servo kit and replace parts. MIke

Thanks Moss and J M, Can you refer me to site which gives details of the strip-down step by step.

You need to eliminate the hose and its connections first before contemplating purchase of parts and a strip-down. If there is a vacuum leak anywhere it should have a significant effect on running performance, so the first to do is eliminate hose and connections. If you find it runs well with the servo end of the hose plugged, but poorly with the hose connected to the servo, then you start on the servo.

Could not find a site with instructions but if you look back on MGB Technical list back to 2nd January there are 39 posts on my Bendix servo unit. I take it it is a Bendix servo unit we are all refering too.
