On behalf of another VRV member - In the Comet aluminium Frame Tie F106 there is an internally threaded bush F110 that the gearbox bolt upper F48/7AS screws into.
Here is the problem. At some time in the dim dark past a dastardly dodge was performed. The steel bush F110 was removed or lost and the bodge was to simply replace it with a nut! This left the end of the gearbox bolt with room to move about causing some distortion/enlargement to the hole in the Frame Tie that was designed to accommodate the F110 bush.
So now to rectify but there are some unknowns.
1. What should the ID of the hole in the Tie Frame for the bush be??
2. It is assumed the hole (once fixed) will need to be line bored to match up with the inside of F117 ?
3. What actually should be holding the bush F110 in the frame tie F106? If interference, how much?
4. Is there anything wrong (from a structural perspective) of enlarging the existing but misshapen hole in the tie frame and fitting a made to fit bush, keeping #2 in mind?
5. Given that there is no stress in that part of the Tie Frame, could the hole be repaired with a form of Liquid metal - Loctite has a few such products in their range?
Sensible suggestions sought.
