What can I use to grease this?

[dlundblad]

This is the PTO shaft on my mower.

My lock and lube is too big as is the normal fitting that came with my grease gun. Any other suggestions minus disassembling? It’s the yoke/ u joint just off the gearbox

replace the zerk with a 90 degree

Wouldn’t a needle type extension work?

This tool. I use it on semi truck steering shafts all the time. Looks to be the same as the one you are working with

Would that throw the shaft out of balance?

Technically, yes. But I guarantee you it's not balanced now.

Dismount the mower deck enough that you can pivot it and open the knuckle up so it can be greased.

My Isuzu has a greasable U-Joint but I cannot get access to grease the zerk fitting even with a needle extension. So I said to myself just it let wear out & I'll replace it with a non-greasable sealed U-Joint. But after many many thousand of miles that U-Joint is still intact & does not wear out. I can't believe it. I remember I greased it with Mystik upon installation more than 15 years ago. It's a Dana-Spicer U-Joint , BTW.

I was able to get it. Long story short, all the way up to even out the shaft and yoke with the fitting at 12:00. I was able to use a normal fitting.
