How do I remove the slide arm on my 643 bobcat

I would bleed the line or system to get the air out.

Most likely yes, it is an 8. Best thing to do is take the bracket off the alternator to remount it. Then put the alt back on with slide/adjuster loose.

That's one of the first things that came to mind as I was reading through your post; that the system was air-bound. Are there bleeder valves on the system?

In any event here is a website where you can buy the service manual for your skidsteer; https://mypowermanual.com/shop/bobcat/bobcat-641-642-643-skid-steer-loader-service-manual-download-6566135-10-86/

Sounds as if the transfer pump between the tank and injection pump is the issue. A restricted line from the tank would stop the strongest pumps from doing the job. Fuel filters are suspect too.

this is a job best left to the diesel experts. While you may be able to get it off the engine the settings are critical for engine life. If you get them wrong you will burn holes in the pistons or over rev the engine causing destruction. Diesel pump calibration is done on a bench and each plunger is set to produce the right amount of fuel and the governor is set to cut the fuel at a predetermined rpm setting ( flight idle)
