DB885 Hydraulic filter change

Post by ravilez » Tue Dec 22, 2015 10:43 am

What a drag to find a worn hydraulic drain plug when you want to change the hydraulic filter on a DB885.
Guess this is not a big deal for an experienced mechanic but I tried spanners, vice grips and tube pliers to not avail.
I even filed down the bolt into a more hexagonal shape. Then I searched the internet for a solution and found IRWIN Bolt gripers.
Ordered a set from RS-Online for 42Euros and an amazingly cheap DHL delivery for only 5Euros within 24 hours.
Should I be unable unscrew the drain plug even with this carbon hardened steel conical nut cracker, can I go ahead and drain
the oil simply by unscrewing the filter panel just enough for the gasket to dribble the oil ? As long as the bucket underneath is large enough, I cannot see a problem.

Merry Christmas and a happy New Year

You could undo the ring of bolts holding the filter pan on and let it run into a suitable container.

It might end up a bit messy but it will get the oil out and give access to the suction filter

You could also let some of the oil drain out through the vacuum switch under the pto box.
This would reduce the amount of oil coming from the pan underneath and may make it a bit cleaner job!

Once you've got the pan off it would be an idea to get the offending plug out and change it so next time changing the filter is a simple job.

The plug should be easier to deal with when the pan is off the tractor and on the bench

There is a drain plug under the rear axle, why not use it, you will only have app 3L remaining in the Hyd/Gearbox filter sump cover.

Hi, I do exactly what James F has described, although the PTO sump plug should be removed also anyway. I think the problem is often that people, perhaps in the past, could not be bothered to use the correct size spanner - which I think is "Whitworth" size and have damaged the "soft" brass plug. The IRWIN bolt grippers look good, but I have recently removed the pan and not bothered removing the remains of the brass plug. Just give it a good clean. The brass sump plug can leak anyway so they may be best left.
