on the picture where there is shown a hydraulic oil. you need to measure the drop and assembled boom. The oil should be in the green patch.
if you work with attachments cleaning the fast connections. Can you pouring hydraulic oil the fill dirty.
Yes they checked all of the numbers in an attempt to cross reference to a similar equivalent of the fluid. I spent nearly an hour at the parts desk. It's crazy that there is no specification on what the stuff is.
The hydraulic fluid, oil, and filters are all Bobcat brand. It blows my mind that the gear oil has to be ordered in such a large quantity (like the dealership doesn't have an account setup with them). I may call the dealership in Tulsa and see what they know.
Bobcat has changed a lot of part #'s. Bobcat has an online parts look up that might specify but the service manager should know. I go through this often when I need to pick up something that's not real common. My service manager and parts manager will work together because those part #'s change and it gets confusing.
It is NOT 80-90 gear lube it is differential fluid intended for use with wet disc brakes. Use of normal 80 - 90 gear lube will cause swelling and deterioration of the brake discs. Bobcat first stated selling this for use in the Toolcat and Vershandler, both have differentials with wet disc brakes. At that time the label on bottles was marked Differential Fluid. After Bobcat started carrying a tractor line with wet disc brakes the label was changed to Transmission/Differential Fluid to help signify it is also used in the tractor transmission/differential. Part number 6687120 is for the 1 quart bottle shipped from Bobcat Parts in case lots of 12 1 quart bottles (3 gl). There is also 1 gl. bottles shipped 4 per case or 2.5 gallon jug shipped 2 per case and can be purchased in single case lots.
While Bobcat may have fine tuned their recipe of additives to enhance the fluid for use in various applications it is still a premium quality UTF (Universal Tractor Fluid).
