He covers engine oil, hydraulic fluid, front axle fluid, and air filter in a straightforward, no-frills format, notes all drain plugs are 17mm, and is upfront about skipping the fuel filter. Good for first-time 5045H owners planning this service.
Posted by the James Daugherty channel, apparently an owner-operator sharing his own hands-on maintenance experience.
The owner changed the engine oil, hydraulic fluid, front axle oil, and put in a new air filter, skipping the fuel filter and greasing for now.
All the drain plugs are 17mm, and the owner says everything was easy to get to.
Yes, the owner had no local Bad Boy dealer and went to a TYM dealer asking for parts for a 4820 TYM, which is the same tractor.
The book calls for 1.2 gallons according to the owner performing the service.
