I'm just in the process of changing the 4 spool valve seals (lift and tilt) on my Bobcat 773. It's all gone very well using trip and instructions from both this forum and YouTube. I've found that 2 of the old seals were the black ones, part No. 7931367, and 2 of then are the green ones part No. 6683274. Every instruction I have seen has shown the green ones either being installed or instructions saying to only use the green ones. I went to order them from our UK Bobcat agent and they tell me that Bobcat are always changing what to use between the above part No.s, and currently they say to use the black ones, and that's all they stock now. Is this correct? I've got to say, they don't look as good but what else can I do as that's all I can get and what the dealer tells me to do. What do all you think please.
Thanks, Andy
