[QUOTE="Tazza, post: 3409, member: 82"] Hey there, the seat i bought was from a place called TVH international. They do all sorts of stuff, mine cost just under $200 aussie dollars. Thats for a semi-suspension seat, complete with runners and a seat belt. My dealer wanted $500 odd for a bare seat!!! no runners or lap belt. Ok, your lift arm problem, it sounds like it will too be a problem with your load checks in your control block. The main problem is they are a total cow to get access to. Yes, oil will pour out absolutley everywhere.... Your only option is to drain as much oil as you can before you attack the control block. Getting back to the load checks, to do it rite, i believe you will need to remove the whole block and get the seats machined flat and replace the poppets. It sounds like there is a bit too much wear on the poppets and seats causing oil to by-pass. As you did mention it drops pretty fast, have you tried with the machine off, pushing your heal down a tad and see if they stop moving? if it does, it could be your centring spring on the back of the spool has lost a bit of tension causing it to not centre correctly. As for your glow problem, i have seen other people wire them up like that, they wired the glow plugs to the starter so when you crank it glows. Have a look in the back where the start and glow solenoids are and remove the extra wire that has been put from the starter to the glow solenoid. There isn't alot of difference between the 743 and 743B model, there are a few small things but you can work around that. If you need any other info just give me a yell! [/QUOTE]
