[QUOTE="Tazza, post: 3295, member: 82"] You can indeed get access under the ROPS and through the engine bay, but its not easy! Its even harder to remove the block. Here is a scan of what the block looks like with all its internals: [IMG]http://users.tpg.com.au/tazza_/bobcat/Spool_valve.jpg[/IMG] If its just 1 section your having problems with, make sure you change all the seals in that section. You will loose a fair amount of oil, but you can't help that. Give the block a good de-grease before you start to help prevent geting dirt in your system. I have replaced all my seals on my 743, but it was all done out of the machine which made it ALOT easier. Just a little trick, use a dolip of grease on the spring when re-installing your poppets. This will help hold the poppet to the spring so it won't fall off. Grease ALL O rings before assembly, this will prevent them pinching and causing leaks. Good luck with it, i'm sure you will do fine. Any problems just give us a yell. [/QUOTE]
