[FORD3351976]

New to me Ford industrial 335 tractor Model #CU221C, (1976?)
with loader 19-529 (730)
with backhoe 19-388 (750)
I am going to change all the fluids so I have service starting point.
I need help with which fluids to use as not to harm this tractor.
Some original recommendations no longer available?
I am located in WI but tractor will not be used in winter months.

Did I miss anything?
Quantities would be nice but I do have shop manuals on order
for all systems.
Sorry for long post, thanks for sharing your knowledge!

Welcome to TBN!

Engine antifreeze - at this point, Prestone mixed to your coldest weather specifications
Engine oil - a good grade diesel motor oil. Probably 15w40
All other oils - a hydraulic transmission oil from New Holland, Deere, Kubota, Cat, Tractor Supply, Napa can be used.
You may save a little money on your loader/backhoe and power steering by using AW68 hydraulic oil.

Is it a power shuttle (F/R on left of steering wheel and no clutch)?
Oops! If I was paying attention to your post, the model code tells me it is an 8x2, no PTO.

Engine oil w/filter 7.0 qts
Coolant 2.75 Gallons
Transmission/rear end 13.8 qts
PS 2.0 qts

I will find the loader/backhoe for you 730 loader/750 backhoe setup

 

[TractorTech]

730 system capacity 10.5 gallons plus 6.5 gallons for 750 backhoe, but unless you purge all the cylinders you won't need much more than about 8 or 9 gallons. Don't forget to change the filter on the loader lefthand upright on the bottom

Do you have a source for the this filter? Also possibly for the air filter? I have been having trouble finding these items. Thanks for the info and help!

Loader filter:
New Holland 7702218 r/b: 86546604 Kit
Napa 1590
Wix 51590

Outer Air filter:
New Holland E6NN9B618AB
Napa 6449

Also, you have 1976? Date code should be something like 6B16B which would be 1976, February 16

Wow the help here is stupendous! All filter and fluids changed. Now the little backhoe runs so much better. Hydraulic filter may have been the original and it was a plugged up mess. Sure there are a few small leaks (drips) here and there but I couldn't be happier with the performance.

wow was that hydraulic filter a mess. Might have been the original. @2885 hours on the clock. All systems operate so much better, smooth now, no stumbles and jerky movements. Engine is also much happier. Thanks!
