ZF286A Oil Leak

[Brian Will]

I have an oil leak on the aft end of a ZF286A gear somewhere on the hydraulic pump. I think it’s coming from the lower left Allen key plug (see attached picture). I know the website mentions leaks from the hose mounting nut but that’s dry. Question is, can / should I pull each of these Allen plugs and use sealant to stop any leaks? I’d always followed the guidance not to seal straight thread fittings only tapered. If okay to use should it be yellow or blue sealant? 

Thanks.

Nothing I see is is of much of a concern…………………..But, try this. Remove the allen cap screw ( that one or ??) , ONE at a time.. Use RectorSeal 5 on the threads and  entire cap screw and reinstall– Use  Common sense as to torque.. Two of the screws are longer as they hole the pump to the gear. The 2 shorter screws hold the pump together.
