Fixing up the Yanmar mini excavator - (part2)

Andris, that lever according to JapanMachineryParts is the control for the PTO. I’m pretty sure you’ll find that thread on that nipple is NPT,it’s tapered so that as you tighten it, it will seal itself, no thread tape required to prevent tape getting into the system and blocking control ports. I really appreciate a man who looks after his machinery and you do that very well mate, the new paint job was the icing on the cake. Another splendid video Andris, heaps of content, wit and the commentary was great, as always. Take care mate

I love your ingenuity to make your fixes and upgrades on a budget that we can all relate to. Well done Andris. I think this project deserves a “Super Mom” seal of approval.

Good job! At 2:06:20 To remove tools from the tail stock, crank the handle to retract it fully. It will push the tool out for you. They are a friction fit with the taper. And the flat on the end is to keep the drill chuck or the taper adapters from spinning in the tail stock.

Found your channel only last week thank youtube algorithm not. Enjoying your videos, your funny, don't pretend to know everything and keen to learn. Loving the dry sense of humor. Keep it up.

Your video is like a DIY adventure from start to finish! Fixing buckets, hunting down hydraulic leaks, and even throwing in a horn for good measure. The "Fixing" and "Mending" sessions add a nice touch of mystery and creativity. The variety of tasks is impressive, and it seems like you're leaving no stone unturned in making sure that Yanmar ho is ready for whatever comes its way. Looking forward to seeing the paintjob magic and the final wrap-up!

hello the big valve on the left with several hydraulic pipes is for inferring the controls from left to right and vice versa and the lever on the left like a parking brake is a brake for the swing

Thanks! I can not tell you how many people have told me that you truly bring back REALITY

1:04:02 the worlds most badass hydraulic foot lever 😂

Someone may have already said this, but that rotary valve under the left side of the seat with all the hydraulic lines changes the control pattern. Most likely between ISO and SAE patterns. Different patterns change what functions control lever movements activate.

That lever by the seat is for the ejection seat. One time use..

Love you, Bro. Your humour, your Family, your Values. You give us something that most have lost since the 1960s; it is called living and life; thank you so much for including your "Super Mom, and cute nieces". From an equally crazy Canadian, though just a little older

As usual you're able to get things done. Great video.

I believe tat steel is Hardox. The left lever at the back is the PTO selector lever. The pedal to the left is a 2 speed pedal. The lower lever under left consol could be to widening the tracks if its equiped with that option.

Hi Andris. Your personality and your whole being is an absolute credit to you, you look at every job logically a fix it accordingly. And you mange to do it all by yourself, I love watching you work. It gives me hope, I retired many years ago. Now I can’t physically do much, but seeing how you work is a great tonic. I thank you from the bottom of my heart. Never stop doing what you do, you’re more than just a video. The Yanmar looked fantastic after the paint job and the stickers. She looks brand new. Keep up the good work ✅

America loves you & all your family.. Thank you for just being you....

Good video, even though I have zero interest in this machine, your video had me interested in the process of repairs for the full 2.5hrs!👍

The new fitting is likely a NPT (National Pipe Tapered) fitting or a BSPT (British Standard Pipe Tapered) or vise versa. But if the old male to male fitting is Parallel its likely an "Inverted Flare" fitting of some type. It could be JIS ( Japanese Industrial Standard) "30° Male Inverted Seat" which are interchangeable with BSPP (British Standard Pipe Paralell) connections. There seems to be a concave bevel on the face of the male fitting on the ID. If you look into the female fitting on the boom and there looks like a convex seat or like the tubing/ferrule end on a compression fitting (the nut side) its likely an inverted flare or BSPP/JIS Female. If that IS NOT the case then I would say it might be a JIS Tapered/BSP Tapered thread. It could also be "NPSM (National Pipe Straight Mechanical) " which would explain the 30° seat and straight threads on the old male fitting, and the fact that the new fitting will thread on but won't go in "all the way" and wont seal. But i doubt this. Both NPT and BSPT fittings seal on the threads (with use of pipe sealant) and are dimensionaly similar but not interchangeable., they have the same thread size but differnt pitches, they will thread together but not seal. Which would explain the leak you had... (This could also be lack of thread sealant) NPT (National Pipe Tapered) fittings will thread into BSPP and BSPT (and JIS T and JIS Inverted Seat) Fittings but wont seal properly, (even with pipe sealant). BSPT Fittings will thread into BSPP fitting and will seal with the aid of pipe sealant. Since its a Japanese machine the old male fitting MIGHT be a "JIS tapered" (aka BSPT) and the boom side female then is likely JIS Female Tapered (aka BSPT, aka British Standard Pipe Tapered) or a BSPP Female which will seal on the threads To a BSPT male without a gasket or oring (but with thread sealant) If the boom side is a BSPP female and the male fitting WAS a "BSPP Oring" (since your said the old male appeared parallel) and that oring has perished/been lost, but these are usually only present on swivel fittings .. if any of this was the case though it would likely leak, unless a LOT torque and pipe sealant/old paint (visible on the old fitting) somehow molded themselves enough to seal. But as i said if the old fittings male threads are parallel and there is no place for an oring, and the female fitting looks to be a CONVEX cone in it my guess would be be some sort of inverted flare fitting or more likely a JIS ( Japanese Industrial Standard) "30° Male Inverted Seat" or BSPP both of which has parallel thread connections and a fundamentally interchangeable.

Holy Heck! Two and a half hours! I gotta start planning my Fridays around these.🤓 Cheeeeers Lad!

For your track roller pin zerk fitting problem, could you weld a round pipe, similar to what you had. Just thread on some pipe caps on the ends. When it's time to lube them, unscrew the cap, service, and screw the cap back on.

Haven't even started watching but i give the thumbs up 😂. Friday night with 2 and a half hours of mad DIY stuff from Andris what more can you want 😂
