MK 1 car. Could any of you chaps explain to me the function of this device?   I renewed the rubbers many years ago but I don't really understand how this functions. The barrel nut in the middle, to the RH/LH threaded rods must have a tension to it? Thanks Bruce |

Hi Bruce,
That is a stay bar, that restrains the engine from surging forward, under hard braking or frontal collision. It doesn't need any tension, just tight.

Glad to see that Herb has sorted your query Bruce.
As a aside to his comments this type of stay bar is only employed on Mk1 and earlier Mk2's prior to the introduction of the 23 spline input shaft gearbox from around 1962 onwards. If anyone wants to see this set up and does not have access to a parts book they should so to the Moss Europe site and check out the MGA gearbox picture as this set up is exactly the same as the Riley and you can purchase some rubbers required for this set up. I hope this is of some help to others?

Thanks Herb & Nigel, I am well versed on these restraints, the MGB has a few versions during its production. I suspected this may be the 'only' function of this device, however the factory nomenclature threw me off.  In the spares list the early version cross member/gearbox mount this is referenced as, "Link - engine control" while the later crossmember gearbox/mount a "Stay - engine steady". FWIW the MM and transverse engine BMC cars, (Mini, ADO16 etc.) has such a device, at cylinder head to body, "engine steady" to mitigate torque influence to engine mounts etc. I appreciate the confirmation.
