Can anyone tell me which lubricants were originally specified by Harrison for the 13 inch L5 – This one.

Is there not a diagram either inside the covers or inside the opening door?

For most things a hydraulic oil is acceptable whether standard or AWS (anti wear)

For the head stock gears ATF the red stuff i can recall being recommended. After some checking for you Tractor fluid is ATF and in turn a mix of hydraulic oil.

I used ATF in my scrapped 140 head and so does a mate with dare i say it the 11". Mine didn leak, a rarity.

Gearbox a bit sketchy but dont get EP. An hydraulic oil of H68 or AWS68 is acceptable.

General oiling hydraulic 32 or AWS32, there is no pace on any Harrison that uses grease, its all oil. A grease gun topped up with H32 fine for squirting in the nipples throughout.

Thanks for the reply Jon – useful info.

Never thought of looking inside. I will do so next visit.

The machine is only used intermittantly for maintenance jobs on our two big pumping engines (here if of interest) so servicing tends to be a bit neglected. Good job it was produced in the days when things were made to last.

Hi There,

I have a 9" L5 and the specified oils were all old grade names – a local supplier narrowed it down to Shell Tellus 68 which is an ISO 68 grade hydraulic oil – local engineering or motor supplies hsould be able to supply a similar oil.

Neil that is hydraulic T68 but can get now the AWS32 and 68.

On my earlier Harrison something like this http://www.smithandallan.com/prodpage.aspx?id=1839 for the head and general oiling of slides etc, its also cheap at £13 plus postage for 5Ltrs.

This is a bit thick unless only for the Norton gearbox http://www.smithandallan.com/prodpage.aspx?id=1840 Or just get the T68 hydraulic which will be similar viscosity to ATF D2. Wouldnt put this on the slides though, you can feel the drag, H32 ideal in that respect.

Latest update

Found a label Jon – not inside where you suggested but on the back of the headstock facing the wall – very convenient!

Sent in thin, agile, apprentice to read it and this is what he found:-

                                     Mobil               Shell              BP                   Esso
Headstock
Feed Gearbox           Vactra Heavy      Vitrea 41     Energol HP30         Esstic 65
Slideways
Nipples

Motor Grease Cups   UX Grease 3       Alvania 3    Energrease LS3      Beacon 3

 

The only one I can find a spec for is Vactra Heavy:-

Mobil Vactra Heavy – Typical Properties

ISO Viscosity Grade                               100

Next step is to have a chat with the nice man that supplies our oil and see what he has available.

Question – why did this dumb website remove all the extra spaces in my previous post and render the info in the two tables unreadable??

PS. Have found out that I can put them back by editing the uploaded post. However, as the layout in the edit window is different to that displayed on the site this is a time consuming trial and error process. B***** stupid.

Hi TB

Send the table direct to me as a Word document.

I will see what I can do.

Thanks David but not necessary. Multiple edits seem to have solved the problem.

FYI the original tables were copied from text files from MS Notepad, formatted using space characters. On upload strings containing multiple spaces were collapsed to a single character. The post editing function allowed the extra spaces to be re-inserted but the different formatting of the edit box and the uploaded text made this a trial and error process. Maybe one is using a fixed width font and the other a variable?
