Recondition GM hydraulic lifters | disassembly and reassembly | ASMR
A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This space prevents the parts from binding as they expand with the engine's heat, but can also lead to noisy operation and increased wear as the parts rattle against one another until they reach operating temperature. The hydraulic lifter was designed to compensate for this small tolerance, allowing the valve train to operate with zero clearance-leading to quieter operation, longer engine life, and eliminating the need for periodic adjustment of valve clearance.
The hydraulic lifter, situated between the camshaft and each engine's valve, is a hollow steel cylinder encasing an internal piston. This piston is held at the outer limit of its travel with a strong spring. The lobed camshaft rhythmically presses against the lifter, which transmits the motion to the engine valve in one of two ways:
through a pushrod which actuates the valve via a rocker mechanism; or
in the case of overhead camshafts, via direct contact with the valve stem or rocker arm.
Oil under constant pressure is supplied to the lifter via an oil channel, through a small hole in the lifter body. When the engine valve is closed (lifter in a neutral position), the lifter is free to fill with oil. As the camshaft lobe enters the lift phase of its travel, it compresses the lifter piston, and a valve shuts the oil inlet. Oil is nearly incompressible, so this greater pressure renders the lifter effectively solid during the lift phase.
As the camshaft lobe travels through its apex, the load is reduced on the lifter piston, and the internal spring returns the piston to its neutral state so the lifter can refill with oil. This small range of travel in the lifter's piston is enough to allow the elimination of the constant lash adjustment.
There are a number of potential problems with hydraulic lifters. Frequently, the valvetrain will rattle loudly on startup due to oil draining from the lifters when the vehicle is parked. This is not considered a significant issue provided the noise disappears within a couple of minutes; typically it usually lasts only a second or two. A rattle that does not go away can indicate a blocked oil feed, or that one or more of the lifters has collapsed due to wear and is no longer opening its valve fully. The affected lifter should be replaced in the latter situation.

Very useful, no nonsense video, thanks!
If you’re going to all the effort of disassembling the frames from the seat rails, you might as well remove the rust and re-paint the rails.
Vedligeholdsfri tænding +Dynamo 👍🏁❤️🇩🇰
Bonjour, c'est possible de récupérer l'axe entier avec les 2 pâtes de fixation, au lieu de découper/souder les pâtes ?
Good bro, pakai kelistrikan apa salut, ane pakai spul grand aki terkor
Hello, where can I order the ignition upgrade kit??
6 ν είναι η 12ν και από που το αγόρασες και πόσο κοστίζει;
Δώδεκαβολτο χωρίς την ανάγκη της μπαταρίας όπως τα R51
Fantastic work

Um great vid but why the hell did you cut off the brackets and reweld what appeared to be the same/new brackets? Why not leave the old ones? Had me until you started cutting/welding.
I was wondering the same thing. He probably wants to sit lower, or either the new brackets are slightly raised.
👍👍👍👍👍👌👌
Buraz koja je to struja ? Gdje si je nabavio ? Koliko košta ? Super zvuk ! Volim kako si ga sredio. Mašala ! 💎
Bravo majstore svaka čast👍
How many meters of fabric do I need? for e30 seat's front and back seat

What good does it do to do a tutorial if you're not going to explain what/why you're doing?? SMH
Kind of wondering why the brackets were cut off too. Complete mystery
@@robw7205 look like brackets cut off and Re welded back on to adjust the height range 🤷♂️ Apart from that very strange video
Sorry for the confusion, I shot the video simultaneously. The slides of these seats are old technology. I mounted the seat slides of the 90s on this seat. Now it's solid and works fine. regards,
Where are you based! I need my recaros done!?!?
