Huckerby}26.7.39. B.V. FRONT SHOCK DAMPERS. We have had a certain amount of trouble with B.V. front shock dampers losing their load. It appears that this is caused by pieces of metal becoming trapped under the main valve: further, these pieces of metal appear to originate from the interlever when the main shaft is pushed into it. At present when the main shaft has been pressed into the interlever and removed, the interlever is washed in paraffin and blown off. This is not sufficient to detach pieces of metal which are raised from, but still attached to, the interlever, subsequently when the interlever is pressed in during the assembly of the damper these pieces become detached and fall into the damper. A broach has been ordered for production and until this is in use special care should be taken to prevent the above happening. Rm{William Robotham - Chief Engineer}/HFP. | ||
