920 cat loader...

920 cat loader leaking transmission oil out of hydraulic pump Weep hole

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Could it be the seal on the hydraulic pump allowing oil in the chamber between the transmission and hydraulic pump letting oil out of the weep hole. Only leaks when transmission is in gear and under load

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

Will you need to check on this is at the hydraulic pump mounting if it's coming out of the small weep hole then it's a problem with the hydraulic pump itself. It would be excessive internal leakage within the pump. Use a boroscope or inspection mirror to confirm if it's coming from the pump weep hole or if it's coming between the transmission charge pump and hydraulic pump.

If the hydraulic pump seal it is usually more than just the seal causing the pump to leak. Let me know the results and if you need further help with this. We can follow up as needed on here and please remember to take a moment to rate my answers as that is out of sight credits my time helping on the site.

Positive it’s weep hole. Used dye in oil to confirm it is not hydraulic oil
Customer reply replied 3 months ago
Positive it’s not the hydraulic pump. Dyed the oil green. Oil out of weep hole is not green so it is transmission oil
Technician: Daniel Wilson,

Thanks for the update. If it is coming from the transmission side and it would be the transmission charge pump that's leaking. I would also recommend checking the transmission filter and your suction screen for any trash or debris that would flag in internal problem occurring. It would be a good idea to run a pressure check to be sure that your pressures are all within spec as well. Let me know the results and if you need further help. We can follow up as needed on here.
