Loader What size flats to remove 16LA cylinders

[mphymel]

I left my TC40D at our deer camp, will need to replace bucket seals.

Last time I did the lift cylinder, I borrowed a buddy's big cresent wrench.

I plan on buying a spud cresent to keep on the machine, does anyone know what size the flats are on those cylinders?

The last thing I want is to get there and be an 1/8th inch short jaw opening.

Any help is appreciated,
Mark
