So, I noticed a bunch of hydraulic fluid dripping below my fork lift. After a short inspection, I noticed it was leaking from the main pump area. I lifting the hatch over the motor and continued use. The lift functions fully, but when I use the lift features (boom, tilt, steering), it squirts hydraulic fluid from/near the upper bolt hole where the main pump mounts to the engine. This is not the pump for the hydrostatic transmission; this pump is for the hydraulic functions of the lift.
I wondered if it was a seal kit, so I called all over the USA for a seal kit. Not available. Discontinued. I did find a couple of the individual parts of the seal kit available, as well as an entire pump ($1100 ). I decided to continue my search. I get in touch with a parts guys who then tells me he's skeptical that its the seal kit. Evidently, there's a Cummins part that fits between the main pump, and perhaps that is cracked. He said that if the seals of the pump were faulty, it would not have any pressure. He was going to check with Cummins. Any help/advice/experience is appreciated. I need a little more info before I have the confidence to order what is needed.
I'll list the details of the lift/motor below, including pics:
Model: 534C-6
Seriel Number: 0388163
Engine: Cummins 4B39-C
Engine Serial: 45266866
