    Dunham Lehr 22 loader cylinder disassembly

    Had not encountered a hydraulic cylinder with an internally grooved tube before attempting to re-seal the rollback cylinder on a DL 22 mounted to a DB 885. Could not remover the rod and piston last winter due to the internal groove I wasn't aware of. I ended up $360 in the hole for a simple...

    Hydraulic power steering - centering the steering wheel?

    Just re-sealed the hydraulic steering gizmo at the base of the steering column on my David Brown. While following instructions for bleeding air from the system I found the number of turns to lock varied between left and right turns by more than one revolution. Nothing I tried seemed to make...

    SAE 10W or 20W oil

    Unobtanium? Going in the power steering on an 885 David Brown where "a good 10W oil" is called for. Can't find straight 10 or 20W. This will be a total change-out of the fluid after a repair. Would it be okay to use ISO46 (20W)? I have a fiver on hand. I see claims it work fine in power...

    885 David Brown with a Danfoss Steering Valve - Reseal Parts

    At the least, the topmost steering seal on the hydraulic steering valve is shot. The valve has filled the steering column with oil making a mess. Danfoss wants right at $100 for a small number (about $5 worth) of o-rings and a seal. Looked on line for alternatives but Danfoss seems to have a...

    DB990 Clutch Access Question

    Have an 81 year old friend with a 990 that he really needs to make someone else's instead of trying to mow with it. Regardless, the clutch is stuck. My manual shows a pull type pressure plate which I have never dealt with before so I don't know what I don't know. Is there a way to get at the...

    Hydraulic Cylinder Question

    My DB885's loader dump cylinder is restricted to about 1/16" in the extend side swivel hose fitting (not the cylinders actual pipe thread fitting. The collapse side swivel fitting is wide open, about 1/4". Is this restrictor factory or an add-on to prevent leverage damage to the cylinder? The...

    "Generic" Parts

    Found the water pump on my DB885 is about to send the fan through the radiator while doing an end-of-season inspection, general clean-up and service. The correct single groove pulley version doesn't look to be available here, although Parts ASAP shows one. Ebay, Amazon, Cross Creek, Reliable...

    David Brown 885 Steering Wheel Upper Bearing Leaking Grease??

    Bought this tractor in early '19. All of a sudden, after seven years of use every time I use it globs of grease-like heavy oil drips on the transmission cover from under the steer wheel. After a period of use the dripping stops. There is a grease zerk in a stamped collar just under the...

    Hydraulic Jack Assembly Question

    What is supposed to seal a bottle /floor jack reservoir/tube to the valve body? It's a 70's Sears floor jack. It had been leaking for a while and using it to support half a tractor while the clutch was replaced finished it off. The reservoir tube to valve body is a metal to metal fit. There...

    David Brown 990, two-stage clutch?

    An acquaintance bought a very used 990. On the surface, it does not appear to have a two-stage clutch. While doing a walk-around with the new owner he asked if the 990's had a two-stage clutch. Told him I thought it should have one, but by feel of the clutch pedal it does not appear to??

    Calculating Hydraulic Pump GPM On A Log Splitter

    Ten years ago I bought an ex-rental Bil-Jax commercial vertical log splitter with a 270 series Honda 8HP engine and a 4" cylinder (o.d.). Because it was rented to the general public safety was more important than speed, hence it is slow. Also required standing beside the splitter and using two...

    Trailer Ball Hole In Forklift Fork

    I see that it is done fairly frequently to move (usually empty) trailers for mowing and such, is it a reasonably okay thing to do? Assuming it is, what is the best method for making the hole. Looking at making a 1" hole - for use on tractor front loader mounted fork, not an actual fork lift.

    Converting from pin-on the quick attach

    David Brown 885 with the original Duham-Lehr loader. This loader uses a single, underslung dump/roll-back cylinder versus the more common dual cylinders on top of the lift arms. The loader works well and is in pretty good overall condition. I'm thinking of converting it to a quick-attach...

    harbor freight 20 lb. sand blaster - looking for tips

    My compressor turned out to be too small to run it back when I bought it five years ago, so it has never been used. Need to sandblast the inside of an old air compressor tank that's becoming an offset pit. The only tool rental in the area has air compressors but no sandblasters. So, I'm...

    Not Sure Where To Post This - David Brown Laycock Clutch Pedal Modification

    I've asked here about the Laycock clutch used on some David Brown tractors before without success. The question had to do with the inordinately high pedal position for the main clutch to engage. The PTO clutch is fine. The pedal is so high when the clutch engages you'd have to be Harry...

    Bending the shifter . . .

    "76 David Brown 885 w/12 spd. I've been at the humiliating age for a while now where everything from swatting a mosquito to working under the dash of my pickup leaves my forearms a bruised, bleeding sorry mess. Add to the list, moving firewood logs with a loader, constantly shifting to/from...

    David Brown 990 Hydraulic System Air Bleed Nipple On Diff Housing . . .

    Helping a neighbor who's 990 hydraulics held more water then oil. After the fluid/filter change I removed the bleed nipple to clean it before bleeding air. Had trouble getting air to purge and soapy water showed no air being forced out of the nipple. So, I took the bleed nipple out, told...

    David Brown 990 Transmission Options . . .

    There are two 990's nearby. one has a three-stick twelve speed, the other a two-stick six speed. Both originate from the same area - the peach orchards of Candor, Montgomery County, NC. I had been told the 990 was a six speed only tractor back when I was looking for parts for my 885's tranny...
