    Yanmar VIO70 valve body leaking between sections.

    So last year I had one valve section, three from the end sticking, I carefully unstacked the sections, fixed that one and tossed in a couple new o-rings. now further up the line, there's a minor leak between the sections so I'm thinking old o-rings plus disturbing them equals ooze. There is...

    What's the pressure for a bucket qick coupler Cat 318

    I have a quick coupler, its from a Cat 318 and it's been adjusted to fit on my Yanmar VIO 70. My question is what's the pressure needed for the quick attach to operate normally? I'm hoping someone with a cat manual source could take a peek. I have the pilot pump that makes 500psi or the main...

    So working a dirt pile the other day, was a pretty hard climb to the top, all nice clay sand, had a nice level spot and was just moving a bit when there was quite a bit of a bang from the track. Spot up by the idiler split, the outer edge was intact but between the outer edge and the center it...

    Trench compaction options!

    So I'm putting some pipe in the ground using the Yanmar mini ex. I'm down somewhere between 11 and 15 feet, its hard pan clay, darned near shale, I'd have a hard time driving a nail into this soil without a good sized hammer and down to about 10 feet its dry dry as a bone! I've almost worn...

    Slobbery Deere, blowby question

    So my favorite big project, Deere 644e with a 6466T engine, well it keeps slobbering on the rear axle from the the crankcase breather, I looked on both sides of the engine for a Detroit diesel sticker but nope, it says Deere. Its a steady fog of blowby, and an oil drip now and again too. Not...

    Ponderings, Baby sized RGN trailer.

    To the seasoned professionals this will seem silly but I have a 15t deckover trailer with a normal light duty gooseneck hitch and I'll drag that with the F550 or the 350. But I gotta say, driving the dozer/excavator/backhoe/roller up the beavertail onto the deck is .. well it gives me the...

    Michelin XTLA date marking / determination

    So bought some used sneakers about three years ago, we've worn away about half of the remaining life in that time. Half inch worn down to 1/4 or so above the TWI marks. They have a few areas where there are no cracks. I figure when they start loosing air then it'll be time to replace them...

    So have a decent JD Loader and below 20F it seems quite appreciative of a snort of ether in the outer air intake. There seems to be an ether start button on the console but all the underhood bits have been burned away from its previous occupation possibly working in an active volcano. Napa...

    Bucket pin shim sources.

    So the nifty little Yanmar has 50mm bucket pins and I'm looking at where to get those shims from besides Yanmar. Most pointers seem to point to the UK providers who offer some assortment packs and will combine shipping. it seems shimming would go a long way to keeping the dirt out.

    Yanmar VIO pressure relief for PTO valve

    So the Yanmar vio70 has a fairly kickass hydraulic system there's a PTO valve that on this machine was set up to run the tilt bucket. I opted to put a thumb on the stick as that'll be something I can use a lot of! Anyway after a small mishap, I went looking on how to reduce the pressure on...

    644E Deere with a clunky rear end pivot.

    So since it arrived, this 644E would make an awful racket if you filled the bucket right to the top and then drove down some road bumps too fast.. With the help of a bottle jack the other day, picked up the tail and when the weight came off the rear axle, it dropped about 1/2 to 5/8 where the...

    John Deere 6466T fuel injectors/pump

    So have been chasing oil leaks on the 644E loader, there is one leak on the throttle shaft and well, I like to try and keep the oil on the inside and the dirt on the outside.
