65 transmission fluid cap

[Paint Horse]

I could use some help. Bought a MF65 not too long ago . Been using it, then noticed one of the loader bucket cyclinders was leaking fluid pretty rapidly. . Had both rebuilt, no issues. Now I need to fill up the hydraulic / transmission hold. Previous owners have mangled any flats that were on the filter cap. Cap is seized tight.
I've tried channelocks, visegrips, pipe wrench, etc to no avail. Any body have any ideas on how to loosen this before I go ballistic!
And.. anybody know the correct Massey part number so I can order a new one? I keep finding ones that will fit 35s,50s, etc, but not listing 65s.
Thanks for your help. This is all new to me.

I cant help you on a replacement but if the stuck one is
steel Id weld a nut to it. Then give it a firm whack straight
down prior to trying to loosen it.

I've seen someone loosen stripped nuts/bolts with a hammer and punch by hammering on the sides of the bolt in the counterclockwise direction.

I use a sharp chisel on the outer edge to knock the tight cast fill caps loose. Usually, a few good hammer strikes will spin it loose.

Thanks, I appreciate all the help . Was finally able to get the cap loose with a chisel, and have ordered a replacement cap. Thanks again
