Ford New Holland 914 mower deck gear box

[Bob Jones]

I had the gear box rebuilt for my Ford New Holland Model 914 6' mid-mount mower deck and it works great EXCEPT I can't find the right drain plug for the gear box. I can come close with some substitutes but the grease still leaks. I can use a 15 mm plug and turn it a couple of turns but it still leaks since the threads are slightly different and I'm hesitant to turn it further and strip the threads. Everything works on the mower deck and gear box but I can't use it if I can't keep the grease in the gear box and apparently the manufacturer does not make the parts anymore. I'm looking for anyone who can provide the right drain plug for the gear box for the Ford New Holland 6' Model 914 mid-mount mower deck. Thanks
