Hello,
I am looking for some help regarding my new to me Yale diesel forklift.
It's a GDP060TFNUAE087 model and is from around the year 2000.
Serial no. E177B17347U
I purchased the forklift and dropped it off at my shop. When I returned a week later I had a leak.
I checked all the dip sticks to see what fluid is low and I found out the dip stick in front of the engine in the area around the gas pedal, beneath the floor plate is very low.
I do not have the service manual, that's why I am reaching out.
Question:
For what fluid is the dip stick beneath the floor plate?
Is it for transmission fluid? If yes where can I find the lid to refill it? Or do I need to refill it trough the dip stick pipe?
If someone knows what exact fluids I need for the forklift
Would be very helpful. Like what transmission, engine oil etc.
I have a hard time getting a mechanic out and I need to run the forklift for 2 hours but don't want to run it without all the fluids on working level.
I am a woodworker and not a mechanic, and English my second language that's why I might have not used the right terms to describe my problem.
Thanks for any help.
I appreciate it.

Fishmech,
the JD tractor fluid will probably work but depending on which transmission it has in it some of them took a special fluid. None of the newer models use red transmission fluid, they stopped that and went to clear tractor type fluids long ago. The service spec says to use JDM J20C.
Engine oil: 15W40 API CG4/CH4 ACEA E3/E5 Mil-PRF-2104G
Hydraulic oil: SAE 10W (todays equivalent is AW32)
Antifreeze: 50% water and 50% ethylene glycol boron-free
Fuel: #2 diesel
As for the model number? i'll give you an example and description of how they break down.
Let's say you have a GDP050TDNUAT083
GD - Diesel (engine)
P -Pneumatic (tires)
050 - capacity (how much it's classified to lift, in this case 5000lbs)
T - Special designation (any special features added on other than stock)
D -Design Series (not sure on this one, will vary depending on what year)
N -Mfg Source (in this case North America)
U -Engine model designation (in this case a mazda engine)
A -Transmission type (in this case an automatic power shift)
T - Mast Type (in this case a triple stage mast)
083 - Retracted or Collapsed mast height (inches)
This is just an example from on older model breakdown guide i have. There may be an updated newer one with better information for newest machines built after this was put out.
Mathias,
The D in the GDP means it has a diesel engine. Depending on the year and size of the lift, will affect the size of the engine. The J20C is just one of a couple of fluids that can be used. We can usually find it at any NAPA store. Mobile, Shell and Tractor Supply offer Tractor Hydraulic Fluid that is equivalent to J20C. Good Luck
Good evening Fishmech,
Thank you for your reply.
I was able to get the john Deere transmission fluid.
Unfortunately I do not have the manual for the forklift and I can't find much information online.
Do you know if all GDP forklifts are the same? I found some other posts of GDP forklifts but they have different letters after gdp040.
Thank you!
Mathias,
The leak should be transmission. You will need to use a funnel that fits inside the dipstick tube to fill. The fluid used is Sheel Donax TD, John Deere tractor oil J20C or Hygard Fluid. If the fluid looks red, someone has added dexron to it. You should have an operator's manual attached to the back of the seat that list most fluids. The year of the lift is 1997. Good Luck
