Suspension Strut Cylinder Tear Down | Making Flogging Spanner

This video is a job we did to tear-down, disassemble & reassemble a hydraulic cylinder for a Caterpillar 740 Articulated Dump Truck. This is the front suspension strut cylinder on the truck, the cylinder is bypassing and the seals on the cylinder gland are destroyed. This shows the step by step process to disassemble and tear-down the cylinder, install a new seal kit and reassemble the cylinder. First we use our 150T Hydraulic Press to help with the disassembly and tear-down of the cylinder. We also need to fabricate flogging spanners to remove the gland and 4" inch nut from the cylinder. We clean and inspect all the components before installing a new seal kit and re-assembling the hydraulic cylinder in our press.

This post brought back many memories of working mostly over in the US refurnishing, updating our large printing press gearboxes. Sometimes spending months working at national newspaper facilities. I really enjoyed those times, mostly before 911. Sometimes having to make tools just like the C-spanner, with a difference. This old engineer would make them with 2 location lugs instead of 1, it worked fine. He would say that it spread the load over 2 slots instead of 1. Working on the end users premises was fine, even when their engineering staff were watching me work. I found that working in a logical manner, just like you do, and keeping your working area as clean and tidy as possible, gave the customer confidence in my ability to do the job. Now you have all that space in the workshop you could build Homey a doggy assault course inside out of the rain. Another great post by you pair, thank you.

[@tommi_mk285]

When you talked about the nut being tight I remembered one thing my mate told me. He works in a place that makes engines for large ships. According to him, when they tighten the bolts what are effectively head bolts, about 110 mm in diameter, they have a hydraulic machine that stretches the whole bloody bolt a wee bit. Then they just sort of hand tighten the nut and release the bolt. Not coming off without the stretcher machine I hear.

[@CuttingEdgeEngineering]

Yeah mate very common way to tighten a bolt if the are big fuckoff bolts!

[@peteacher52]

Just make sure the nuts are not those from Bob's Buck-a-Pop Shop!

[@forrestaddy9644]

Stretched many a bolt back in the day. High pressure steam joint flanges are held together with continuous threaded studs with nuts on each end. If you know the root area of the thread, the mid nut length of engagement, the number of studs, and the modulus of elasticity for the stud material, you can mike the relaxed vs stretched length of the stud, and with a calculation determine the clamping force to a high degree of accuracy. With a little experience and a keen ear, you can listen to the sound of the blows of a single jack on the slugging wrench and draw up the studs as accurately as if you miked the stretch. Hydraulic fastener tensioning systems are great time savers but very expensive and you don't always have access in a crowded space to install the hardware and run the hoses. Speaking of clever fastener tensioning methods, who knows about stud heaters?

[@totojejedinecnynick]

makes sense since tightening bolts to a prescribed torque is just one mean how to create preload/stretch of the bolt - which is the goal. We don't really care about the method used, we need that preload force - and hydraulics should be able to deliver. FYI Method - accuracy By feel ±35% Torque wrench ±25% Computer-controlled wrench ±8-15% Turn-of-nut ±15% Preload indicating washer ±10% Bolt elongation ±3−5% Strain gages ±1% Ultrasonic sensing ±1%

[@Realtime1501]

Another one is using what we call Supernuts it's a big nut with smaller bolts through it in a circular pattern that gets tightened on a big hardened washer as you torque the smaller bolts

He noticed the shaft seals had been installed "backwards" that is with the expansion springs outboard. Ranting about it and wanting to return the whole damn thing (four vacuum pumps on a demand setup so either 1, 2, or all 3, would run and the 4th was for redundancy). I said: "Its a vacuum system". He: "So"? Me: Vacuum system. The seals are in the right way". Silence. Then he hangs up!

What keeps me coming back to this video is the making of the flogging spanners. So much of what I do for work (and what I love about mechanics and loved about machining, back when I got to do it) was the super mechanical, left-brained, literal way of thinking. That whole bit with chalk in laying out the flogging spanners, especially the first one - "we want it beefy, yeah, that looks right" - reminded me of the intuitive way that an interior designer or dressmaker thinks. It's deeply impressive to be so good at both ways of thinking.

@@liamthompson9342 I think it’s carb cleaner, if my memory serves from reading other replies. With so many comments it takes a while to find some of his replies. A dedicated episode going through stuff like the would be gold!

Having dealt with fasteners in aviation that were tightened to inch-ounces, applying 6k pound-feet to a fastener is almost incomprehensible. That said a 1000 pound mass hanging six feet from center counts as that torque figure, if your mate is ever out of town or whatever.

Notice the Schrader Valves on this strut… same as on a landing gear strut

[@BobOBob]

At some point upward, too, they ought to use different units. I believe this would be 1.0 ton-yard, for example. Though it's probably all bananas to Kurtis.

[@philouphil]

extraterrestrial units of measurement. Team metric

[@SeanBZA]

@@francisschweitzer8431 Yes but those you normally assemble using both a big bath of liquid nitrogen and an even bigger oven, so that you get the 0.1mm clearance for just hand assembly, before the temperatures equalise, and they become one unit.

Thanks for showing how to fabricate tools to handle stubborn glands and nuts. Have you made any to use with an impact gun? That's why most parts washers end up with just a discharge hose and separate brushes everywhere I have worked. Thanks for the assembly tips Kurtis.

[@CuttingEdgeEngineering]

Hey mate glad you enjoyed it yeah have made quite a few sockets to go with the impact gun

[@haroldhawkins9370]

Nice job Kurtis, I like how you go that extra mile on your jobs.

[@samuellashbrook6353]

I love how you explained what each seal does and why each one is where it is. 👍 Awesome 👍👍👍

[@CuttingEdgeEngineering]

Glad it was helpful! Thanks for watching

One of my favorite episodes.

[@jimd5788]

[@allenbrown7820]

[@jacquestournebize1268]

[@kiblerjim]

Thanks for another fantastic video!

[@burbman60]

Curtis, you have such a great mechanical vocabulary. Accurate words for parts, processes and actions.

[@twasbrilligandthesli]

Always a pleasure! Thank you Karen, Homey, and of course, Kurtis.👍🏻😁💚

[@crazyrat51]

Very much impressed with the "gas axe" work!!!

[@MrChevelle83]

I work at a steel mill here in usa, we call those Knock wrenches or hammer wrench. I used 36mm up to 95mm and they are waaaaaay heavier that the ones you cut out. All of ours were forged and the 95mm weighed at least 6-7 lbs and was one heck of a work out to use!!! I did a reseal on a 5 inch cylinder and it was quite aggravating at the resistance on them new seals trying to get it all back together. CEE never disappoints!

Love the way He finds way to work smarter not harder.
