Have a prime mover...

Have a prime mover LD50 serial number 273 that won’t move my question is I cracked the line and have no pressure so what to check now

Mechanic's Assistant: What is the complete model and serial number of your machine?

Prime mover serial #273 model LD50

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Yes fixing myself pulled filter and cracked lines

Mechanic's Assistant: Is there anything else the Equipment Mechanic should know before I connect you? Rest assured that they'll be able to help you.

Every thing else works but when I moved it there was a lot of oil under it been setting in the same spot for a while. Supposedly they drove it there where it sat when I bought it

Hi and welcome to Just Answer.  Ill try and assist you with your ld50

Is the hydraulic oil full? Do you hear a change in engine sound while trying to move like it's bogging down?

No there is no change Almost like the pump isn’t turning was wondering how the pump is mated to the flywheel as I here a noise in the bell housing
Mechanic: RichardH416, Technician replied 1 year ago

I'd have to look your specific serial number up when I get to my shop tomorrow but some have a splined shaft/ geared coupler and I've seen a couple with a lovejoy coupler as well.

That would be great. As I cracked the lines at the pump and didn’t have any pressure then notice the noise as I reved the engine the noise would follow
Mechanic: RichardH416, Technician replied 1 year ago

Sounds like a stripped coupler

Kinda my thoughts as well but thought I would get a professional opinion. Is there away to tell other than pulling it apart?
Mechanic: RichardH416, Technician replied 1 year ago

There will be a pressure test port. With a gauge you can see if you have any pressure.
