How Mechanic Change Komatsu D65 A Dozer Engine Bad Piston Rings Without Disassemble Complete Engine

[@moskal-]

Посмотрев ремонт, по началу не понял, для чего они частично разбирали мотор. Потом меня осенило, они разбирали для того чтобы занесли образив в виде песка в двигатель, и показали нам, как можно производить ремонт, без динамометрического ключа, и регулировкой клапанов на глаз. ))))

[@OggyXXXL]

Образив в полости как бы похеру, если стоит фильтрация, у меня в поддонах килограмы Образива в виде щебня и грязи ездят периодически, никаких проблем. Динамик хорошо, но с набитой рукой все делается тоже, тем более на промышленных моторах, где болты не по полдюйма

[@user-gs5pm5uc4l]

@@OggyXXXL видимо в Пакистане разный подход к ремонту. Где-то моют, тряпочками трут, а тут так, на песочке, да на на глаз.

[@richardmessenger9474]

They use the traditional old school method for torquing the bolts...you keep tighten it until you have two grunts and a groan..😂😂

I loved the black wax residue off the crankshaft he used to for rod bearing pre lube. Boy that’s a new one I never seen before.

[@karlbraun9564]

Nothing says quality, quite like working on a diesel engine in the dirt, using a hose clamp as a ring compressor, and not a
torque wrench in sight.🙄

[@rheidtech]

Jealous? Its called knowledge and repeatability.

[@frazzledude]

@@rheidtech A torque wrench is necessary for setting the injector travel on those engines. The procedure is to tighten the adjustment to 5 inch pounds when the plunger is bottomed out in the injector cup.

[@rheidtech]

@@frazzledude ssshhhhh

[@blocknyckeln]

or not even oil the piston or piston rings before forcing them into the cylinder liner

[@gsmecanica]

I think they actually scratched the cylinder when removing the piston... with the rod.

[@JesusTorres-qr1gz]

You are absolutely right, some damage may occur while removing the piston, from the endless summer paradise, Puerto Rico, Jesús Torres.

Indeed it is Cummins NH220 small cam engine earlier version for Komatsu Japanese machines. And no doubt in Pakistan engineer is a man who could run a broken ball bearing nor needed a new one…😊

[@frazzledude]

They were a very popular truck engine in the 1950s. They were also widely used by the military and in generator sets. They had a 5.125 inch bore and a 6 inch stroke, and the naturally aspirated version was rated at 220 horsepower, and 262 horsepower with a turbocharger. They also had a unique, characteristic sound.

[@SC.243k]

Fanstastic work 👏👌 thanks my friend👍👍👍👍

[@lzed223]

Did they use the original head gasket with gasket seal? or did they replace it with a new one ?

[@robby-cgn]

it's not important. they use always gasket seal...with new or old gaskets. maybe they don't know what a seal is for?

[@lzed223]

They do all that work only to change the rings on two cylinders ? No new bearings etc.

[@jx14aby]

That's what I was thinking. Seems like if you're gonna pull the engine and remove one head, maybe you should do them all.

Hahah, at the beginning, we knock out the piston with a sledgehammer through the dirty wall of the combustion chamber, then we clean the walls with sandpaper. well, that's right, whatever.

[@japc4326]

The occupational safety and environmental consideration is wonderful. The dirt and sand getting in to the block and water jacket is no great concern. Torquing the heads down is really overrated not to mention rebuilding everything on the dirt. That engine should last a good 100 miles or so.....great job....I'm sure the re-builders also took a nice shower afterwards too.

[@scottberry5266]

Yeah, it makes you wonder 💭 I’m afraid to rebuild my b model cat in my garage thinking might screw something up. My confidence has been restored

[@Mr_Smarty_Pants]

This is a 3rd world country. Safety? The Environment? hahahhaha. It's obvious a double ended breaker bar is a luxury...a ratchet head even is nowhere to be seen...so i wouldn't expect them to pull out a torque wrench any time soon. These poor f*ckers work their as*ses off with what they have and they do it for peanuts, probably 10-20 USD per day...they do it because they have to, to support their families.
