Help With 885 AD3/55 Engine Part

I'm trying to source everything domestically for an engine in-frame but have run into a couple problems locating parts and/or part numbers: Piston rings - no standard bore rings in engine sets or for individual cylinders, only standard bore pistons and rings together. A DB part number would help. In...

Re: 885 Head Stuck to Stud?

Yes. And apart. Exhaust valves are burnt as are the seats. Condition is such I can't believe it would start never mind run without missing. #1 cylinder top ring is broken.

Re: 885 Head Stuck to Stud?

Too stuck to turn out. Kept at it with WD40 and tapping the stud back and forth with nut installed while applying upward pressure. Fought it all the way to the threads. Once there was some room between the head and block I used tree felling wedges and the wood blocks normally used when splitting a t...

885 Head Stuck to Stud?

Starting an in-frame of the engine by removing the cylinder head. It appears the front most head stud, the one right behind the thermostat, is seized to the head. The last two hours have been spent dribbling WD40 between the stud and head while tapping the stud fore and aft. A chisel is being used a...

Re: 885 Ram Cylinder Bleed Screw Leak

That. Is not very convenient! Ollek, you know your way around these tractors, the "connector", the piece with the bleed screw bolted to the axle housing, it won't move forward enough to access the O-rings? I don't see in the schematic where it's attached to the lift cylinder "case" other than possib...

Re: 885 Ram Cylinder Bleed Screw Leak

Lollek, the leak is between the cast part bolted and the axle housing, not the bleed screw itself. I didn't find the part name to enable looking for the gasket, O-ring or whatever seals it. The book I have has a picture of it in paragraph 261, figure 281 - "Bleed The Hydraulic System", but the instr...

885 Ram Cylinder Bleed Screw Leak

Actually the leak is from between the left side front of the axle housing and the part the bleed screw screws into. In an effort to have parts on hand before disassembling, is there dedicated gasket(s) or O-rings or both used for sealing? If it is a gasket, what is the part the bleed screw goes into...

Re: Thermostart Interchange

Ollek, according to the owners manual I have, the throttle should be in the wide-open or full throttle position when cranking a cold engine no matter the ambient temperature. In your opinion is this correct? Recently, I found the engine exhaust clears-up more quickly after starting if the half throt...

Thermostart Interchange

I have a recalcitrant 885 that is a reluctant starter in cold weather in spite of a new thermostart. According to what I have read in another forum - Ford, Massey-Ferguson, David Brown and maybe others used a thermostart to preheat their diesel engines. The various examples are supposed to be interc...

Re: piston rings and bearing shells

Slow to-build oil pressure at start might be the oil filter. I have an 885 with the oil filter in a can/housing, the 990 may be different. Someone had incorrectly assembled the various bits that seal the filter to the bypass and the through bolt. The result was oil in the filter house draining back ...

Re: If it's not one thing it's another. 885 starter drive #

I was born and raised in the northern U.S., a Yankee by southern definition. After living in the southern U.S. for 31 years I am quite aware of a "thing" or an action having different names according to where you were born and raised. Once aware of this it is not a huge matter to accommodate others ...

Re: If it's not one thing it's another. 885 starter drive #

Starter is a Lucas M45G, stamped with #6310J. Near as I can come up with, the DB part number is A-K957340. Amazon sells a new David Brown brand (if that's possible) starter that is supposed to fit the 885 for around $124 U.S. Sounds too cheap to be any good. Found a nearby rebuilder who stocks DB st...

Re: If it's not one thing it's another. 885 starter drive #

It has a roller clutch starter drive. The roller clutch has failed. Local rebuilders use Chinese or Mexican parts that in the past have proven not worth the effort to install. Local parts store have to order the drive from outside their normal suppliers, as a result it is usually much cheaper to buy...

One more thing to add to the to-do list: replace starter drive. When it decided to quit, it quit! About wore out a good mood trying to get it started to move it into the shed last night. Anyway, I have not found online nor do I have literature showing the starter DRIVE part number. In doing a search...

Re: 885 Loader Operation with Going-Away Valve

The term 'going away' was likely morphed from the original term. It does not seem to be a common DB feature. Depending on where the tractor was sold new either everyone has it or no one has heard of it. Probably a dealer thing. Ollek, you may or may not recall that this tractor is due to be split po...
