-cont'd- - 2 - Jnr.{Charles L. Jenner}1/SW.20.3.41. No.7. RE.1683 - Camshaft. The diameter of the camshaft is such that even if the small hole up the centre wanders considerably, it will not fail. Alternatively the central hole can be increased in diameter and the taper plugs at the ends made to suit. We agree to alter the limits as you suggest. No.8. RE.1704 - Oil Pump. The detail drawings should be submitted to Mr.Wheeler for his comments on die casting. We agreed to run the first pump without the bush. No.9. RE.1705. Mr.Wheeler should also give this piece his consideration. We agree to the suggested locking plate which embraces three nuts at a time. No.10. RE.1712. The end limit on the detail drawing was agreed to be un-necessary. No.11. RE.1713. We agreed that the first oil pump should be without a bush, we want to retain the helical gear pump because these come off the machines and require no further quietening. No.12. RE.1706/7 - Connecting Pipe between Pump & Oil Gallery. This is the heart of the engine, and we cannot see any alternative arrangement that would be materially cheaper. No.13. RE.1716/7/8/9. This method of building up a sheet metal sump, is very similar to the 8 h.p. Standard, so therefore the problem of the fabrication can be discovered. We agree to alter the method of welding on the oil gauge plate and also the drain plug boss. If the sump is considered as a die casting, it looks very unsuitable because of the side bulges which forces the die to be made in three pieces. The middle portion withdrawable to collapse the internal portion. (continued) | ||
