Is this hyd. oil going to work?

Ford / NH has went thru many spec changes, and the last one was 134d.. loks as though you have a previous spec.. which should work.

Some find that if they have a 'tired' lift.. the thicker original oil bandaids it a bit.. might also prevent marginal seals from leaking... kinda like using a sae 40 oil inthe engine, when oil pressure starts to drop low on the sae 30.. etc.

I personally like the original spec 90wt oil in mine.. And I can find it locally at TSC stores. Some have reported that in certain parts of the US, the 90wt mineral oil is just not to be found.. in that case you are stuck using the 134d / or equivalent ( many manufacturers universal hy-tran oils meet the 134 spec... etc )

Just a comfort level thing.

In any case, stay away from the 80w90 ep gl-5 gear oils.. it has been discussed that the ep addatives aren't nice to the hydraulic pump innards.

This fellow puts the drainings from the older tractor trannies in my 5-gal/ container.

I re-cycle the old stuff and use same in our equipment. Therefore, we call the used "new" lubricants "REclaimed FROM GOOD EQUIPMENT".

Hope this knowledge helps in the areas where the good ole stuff cannot be got, nomore.
