    Help with a CAT 307X stabilizer cylinder p/n?

    Gray-market low-hours CAT307SSR seeks English-speaking stabilizer cylinders...see attached image for the L/R images and Japanese (I should have said "Mitsubishi") part numbers. They're mirror-image cylinders. A couple of parts people told me there is some kind of CAT in-network parts-lookup...

    Isuzu 4JB1 T (for turbo) - about zero online parts listings...?

    Google is failing me. Surely there's SOME complete parts listing for all variants of the 4JB1 engine online? Hours...no luck. More specifically, injector pipes. More specifically, #2. For a 1997. See, I ordered a complete set from China a couple of weeks back. And not one of them matches...

    who knows their way around ASV final drives & undercarriages?

    My aging ASV MD2810 skid-steer track loader has always tended to chew up the drive-cogs on its rubber tracks. I use it only rarely, and always on my small steep property, often having to turn on slopes. I'm guessing this tends to exacerbate the tendency for tracks to shift sideways and add to...

    drifting cylinder diagnostics

    I've been just living with some droopy cylinders on my old ASV (rubber-tracked loader). The tendency for them to let gravity win has survived through a couple of my admittedly-amateur rebuilds. Is this more frequently caused by a leaky control valve, vs piston seal? (There are no external...

    Cat 307SSR (gray-market) track tensioner mysteries

    Subject machine went through long period of near-disuse, and much (much) rust formed on my undercarriage components. It's gray-market and all I've ever had to ID parts and assembly is a parts-book, from which I've excerpted the attached page, showing the main components of the track-tensioning...

    Foamy fluid?

    I've got an ancient small Gravely disc-type chipper (like this one: https://tinyurl.com/ycwduaj9) that uses a hydraulic motor and pump to drive an infeed 'impeller" (looks basically like a paddle-wheel, turns at maybe 120RPM) to drag small trees etc into the spinning Cuisinart-style chipping...

    un-bending a slightly bent steel track segment?

    This isn't really the highest priority for me, but I'm wondering if there's a specific technique for correcting the bend that somehow occurred in one steel track segment on my quirky not-for-import gray-market CAT 307SSR. I did try the cave-man-sledgehammer-technique for a few blows, but (a)...

    servicing 'offset boom' bushings/bearings?

    My gray-market Cat 307SSR is chronically sloppy at the offset-boom knuckles...I'm sure life's not been kind to them, and my long-term plans include dealing with this. But since I've only got a parts-book (and it's in Japanese), I can't really grasp how these are supposed to be serviced. Can...

    seal-kit database/ cross-reference?

    I'm looking to buy seal kits for these three cylinders, but seems suppliers are clueless about cross-referencing from cylinder number to seal-kit number. I can't remember how I did this before - I think I bought kits from local shop that looked the crosses up. There must be a database...

    tricks for unscrewing hydraulic cylinder heads?

    When I rebuilt the boom/stick/bucket cylinders on my excavator a couple of years back, I resorted to making a custom 1/2" plate spanner wrench. It took a beating to get them loose, but did the job, and as far as I can recall, the one size fit all three of them. Now I'm up against two...

    'generic' test-pressure & setup for hydraulic tubing segments

    I found some damage to some rigid segments of steel hydraulic tubing (rust pitting that looks like it just barely penetrated from spot-abrasion in some cases, physical-damage kinking in others) and bronze-brazed to repair them so they at least "look good," but I'd like to do some down-and-dirty...

    finer points of selecting replacement coils for hydraulic solenoids?

    My skid-steer uses a couple of hydraulic spool lockouts to keep the joystick from being operated without the key being on. One solenoid was in the habit of going out intermittently for some time, leaving me with only a half-operable joystick, before I got into it & discovered it wasn't some...

    "CAV style" Ford tractor double-wide filter units...what?

    So I ordered a few of these filter units to have on hand for projects like this since they were stupid-cheap (calling in it was $30 each with filters). The flip side now is there's no documentation anywhere to be found on them, including the USA distributor, who says the identical item was once...

    Where's all the air getting into my fuel?

    I recently discovered my old ASV MD2810 fuel tank innards are all scummy & rusty when the machine quickly plugged a couple of disposable pre-filters. I drained that tank and while trying to decide how it's best to deal with it I've cobbled up a temp tank, using transparent urethane hoses...

    Mitsubishi 4D32 diesel power unit in CAT 307SSR

    This isn't an excavator-specific set of questions, but really more specific to the Mitsubishi engine - and this is a gray-market machine for which I've got a parts book (in Japanese) and no other documentation. The 4D32 seems to be a relatively common engine in Asia, but not stateside...
