50 Hour Service Help

[Ricco]

The suction screen should be cleaned out with a non-flammable solvant at the first 50 hour service, then at every 300 hour service thereafter. If your model is a hydrostat, then you will have two filters to change on the transmission, a hydraulic filter on the right side and a much heavier filter on the left side for the hydrostat. Here is what should be required for a 50 hour service on a B7800

Change Engine Oil and Filter
Change Hydraulic and Hydrostat filters and oil
Clean out suction screen
Check air filter (replace if too dirty, not worth dusting a engine)
Retorque wheel lugnuts and or bolts (check with your service manual or just hit them with the impact /forums/images/graemlins/laugh.gif)
Check Clutch pedal freeplay (should be 20 to 30mm at top of pedal.)
Check front axle pivot adjustment.
Check starting and charging system (easy one)
Clean out Fuel/water separater bowl.
Lube tractor.

I think that's it. If you do these services yourself, then please take meticulous records, so your dealer won't deny warranty on you, due to lack of maintenance.

P.S. If you go buy a Workshop Manual for your B7800 it will show you how to do all of this stuff with pictures as well. They are worth their weight in gold.

It was awfully nice of Kub to paint everything that nice grey! All the filters are the same diamiter, and can be removed with the wrench that came with your tractor. The engine oil filter is the shortest, the two hycraulic filters are two different lengths, and also, as posted above, the inside of one is concave, and the other convex, where it screws on.

Make sure you have a really large drain bucket, when pull your hydro drain plugs. Also, if you pull one of the rear plugs, on the right and left side of the rear axle case, the head pressure on the fluid makes it shoot straight out against the rear wheel, and not in the catch pan. Either start with a different drain plug, or make sure you have something to direct the fluid stream. There are two oil drain plugs, about three or four inches apart. The oil pan is a double sump, because it goes around the front driveshaft.

It's not hard, take your time, be patient. (I found the most annoying part to be finding an extra set of hands to hold the long filler funnel for that 5 gal bucket of hydro /forums/images/graemlins/smile.gif
