Hopefully the gear comes off the pump shaft easy enough to allow pulling the pump. Got a call on a Friday evening about 5:00 pm at the dealer, local dairy had a 8230 they used for grinding hay and feeding cows. Anyhow, tractor dies about halfway down the feeding alley and wont start. I drive out there, plug in Service Advisor and pull codes, and start through diagnostics. Go into reading and see that there is no fuel rail pressure. Check the wiring circuits etc. and find that the pump shaft broke inside the pump. Its now 7:00pm, flies are so thick it looks like rain clouds, it stinks, its wet....you get the idea.
So I pull the front cover off and yep, I can wiggle the pump gear and shaft. I call the parts guys and tell them to send out a new pump and gear. I install the gear puller and.....you guessed it, gear will not pull off the shaft. I break both bolts off in the gear pulling on it. I tried heating the shaft...etc. Nothing. Now its 11:00pm, I get another tractor, drag this 8230 out to the end of the alley and go hook another tractor to their feed wagon so they can continue feeding.
In the meantime, parts had told me they had the pump, but no gear. We have a Cessna 182, it flies 3 hours to a dealer that has a gear, and comes back. Its 3am, I have cut out the shaft with an air grinder, cleaned up the parts, and get the new gear installed, install the pump, time it, get it running, rehook up the feed wagon and get everything going. Its now 7am, been on that job for 13 hours......
Sooo I say this, In a perfect setup, timing the crank/pump removing the pump, installing the new one etc, would only take 1-2 hours if everything was perfect. I dynode all my work to verify no leaks, and performance was correct. Then wash it up and release it.
SMT (Service Marketing Times) are generated most of the time off warranty claims history. Sooo lets say 50% are nightmares, and 50% go smooth...it would be easy to see the 6 hour charge for AVG times. Bottom line, unless you have the special tools, Service Advisor to diagnose properly and the know how, plus warranty procedure for working on it....6 hours...it is what it is. Is it right?? If you cant fix it yourself, I guess it is!!
