What causes a hydrostatic transmission to slip?
By far, the most common reason for hydrostatic transmission failure is old hydraulic fluid John Deere states that “Operating outside of the recommended oil air temperature range may cause premature hydrostatic transmission failure” Oil must be changed when its anti-foam additive decays
How does a hydrostatic transmission work?
The hydrostatic transmission transmits energy using hydraulic fluid The usual transmission has two hydraulic devices; one working as a variable displacement pump and the other working as a motor connected by hydraulic lines
What causes a diesel engine to lose power?
A diesel engine loses power when it’s hot because the energy from the fuel is going towards heating the engine rather than powering it There are many specific problems that can cause this, including clogged fuel filters or exhaust pipes, dirty air filters, dirty spark plugs, or poor compression
What causes a diesel engine to lose power under load?
