AEW vertical milling machine

[Ian Richardson 6Participant @ianrichardson6]

I am currently rebuilding my AEW Horizon vertical milling machine, i have stripped it all down sent hours removing old oils and grime, stripped and cleaned out all the old oil and sludge from the gearboxes, i am replacing all the original O rings and seals but i cannot locate the oils indicated on the Lub charts, the machine is a late 1970s model and in great condition and appears to have had very little use, i assume the oil grades on the chart are pre ISO grades, can anybody point me in yhe right direction as to the modern replacements.

Original grades marked on chart

Shell Vitrea 41, for main gearbox drive

BP, PREP1 for table

Shell Tonna 33, for leadscrews and slides

Shell Macoma 68, table power feed gearbox

I have the manuals from Tony Griffiths for this machine but it doesnt give quantities or modern grades, dont suppose i need Shell oil just equivalents to the correct grades.

I also need to have a gearbox feed motor worm drive gear made as one is worn, anybody recommend someone for this type of work, otherwise the miller is totally original and complete.

Any help would be appreciated

Cheers Ian

Hi Ian,

If I remember correctly Tonna 33 is Tonna S 68 today (ISO VG 68), the Macoma oils are now called Omala but with a higher number like150, same for Vitrea (starts at ISO VG 100). Here is a comparison chart that you may find useful,
