'M' SERIES BENTLEY FAN.

We have noticed that the provision for lubrication of the Bentley II fan has been omitted on the fans instructed for 'M' series cars - this has presumably been done to bring Bentley fan in line with the Wraith and Ph.III, i.e. the fan to be charged with grease when built and only to be subsequently lubricated after periods of 15,000 miles by re-charging with grease. A subsidiary reason also, being the small clearance available between the lubricator of the thermostat housing. We would point out, however, that on Bentley II cars it is not possible to remove the fan for charging with grease as it is on Wraith and Ph.III, without either (a) removing the radiator, (b) withdrawing studs from the cylinder head.

We therefore think that some means of lubrication must be provided, and suggest as an alternative to the previous oiler the Enots grease nipple (of which we have handed a sample to By/CS.) screwed into the front cover of the fan. The grease gun which is already supplied in the kit, can thenbe used to grease the fan when necessary. This modification would not entail complete dismantling of any fans that are built and would not entail relative expensive drilling of fan spindles which may be already made.

We are ascertaining from the Enots people the correct designation and price of these nipples and suggest that this scheme should be instructed for 'M' series cars immediately.
