I use TDH oil in mine. Transmission/Differential/Hydraulic in mine. Can be bought most everywhere, Walmart, etc.

 

Hi
I am in the uk, no Walmart any idea of ISO rating ?

 

I have a Bolens 1600 Hydro. It came with 90W oil in it. The manual said if you change the hydro oil go to Transmition oil. I filled mine with type F years ago no
Problem.
The 1600 Hydro has a Eaton 11 in it.

Eaton Fluid Recommendations:

Good Luck hope this helps

 

Ok thanks
Can you tell me what the reset switch is for?

 

I never saw one on mine. If you can take a picture.:dunno:

 

i had the same problem for my HT 23, and after looking i found a manual that said use a premium engine oil 10 W 30 or 10 W40 mineral. I took the gamble and it runs fine for a year now. I had a Case 220 that run also on engine oil the manual for it said to use engine oil and not hydraulic.

 

I have seen a few different oils listed in manuals.
The Fluid Recommendations .JPG I posted is out of a Eaton
Repair manual.
It looks like you can't go wrong as long as it’s clean and no water. Engine
Oil is probably the cheapest.
I agree 10w30 engine oil would be a good choice it covers a lot of heat range.
:thThumbsU

 

How about a 5w40 fully synthetic ?
On offer on uk web site just £12.50

 

Or 10w 40 fully synthetic same price?

 

I never tried synthetic in transmition?:dunno:

 

I looked for a Utf oil but could buy it only in large drums, the engine oil a premium one costed me 78 dollar. I dont now if it is the best choice but i flushed the transaxle chanched the filter and planning to chance the oil and filter on a yearly base to be sure.

 

Hi the reset switch is probably for the cruise control. While you are driving you put the switch up and hold it for a second and it kicks in the electric magnet to hold the treadle pedal in the position that your foot has it in. Then you can take your foot off the pedal like cruise control.

 

i would not use syntethic oil it cleans a engine, old engines have sludge syntechic wil remove that sludge and the engine wil have play in rods and so on. So by using it in a pump there is a possibility that there wil be a chance that there wil be play to thats why i dont use it only mineral for me

 

Synthetic oil does not have any additional cleaners or detergents in it than regular oil of the same grading. It will not remove any sludge that a conventional oil would not remove. You can mix synthetic with regular oils (semi-synthetic), you can go from syn to regular and back to syn . Synthetic oils have a man made base as opposed to crude base and does not break down as quickly as well as maintains its viscosity better in all heat ranges. The only thing that syn will do is have a tendancy to leak past a worn seal easier than regular crude stock oils. The only thing I have seen a syn oil do in such applications as maybe a motorcycle where oil lubricates a clutch as well is for a clutch to possibly slip due to its better lubricating abilities. In a hydro there are no friction clutches to affect. An eaton 11 recommends 20w oil that is designed for no wet clutches so motor oil is fine.

 

NSconductor thank you
Shall I go for 5 40 or 10 40 ?

 

I am not sure what would be the best weight. This is only an observation but I would think that 5w40 would have the closest viscosity to 20w. If I had to choose between the two weights that is what I would choose.
