Cylinder Head Testing Valve Spring Force
มุมมอง 294ปีที่แล้ว
This video gives a quick introduction to the tooling required and its usage in checking the pressure that the spring will exert on the valve to hold it closed. If the spring fatigues, the valve can leak open and particularly the exhaust valves will result in the damage of being torched and cut by the exhaust gases.

Perform an Alternator Output test on a Cat Skid-steer
มุมมอง 1.8Kปีที่แล้ว
While this test is done on a 12v system on a skid steer, the operation will be much the same for a 12v commercial vehicle as well as a 24v piece of mobile equipment. Make sure to lookup manufacturer specifications and watch the amount of load that is placed on the battery to keep the vehicle from stalling. This test is helpful if the vehicle regularly needs a boost and when voltage is checked i...

BRILLIANT video. Extremely educational, high production quality, obviously an expert. Keep at it, thanks bud.
This is one of the best videos I see about how to rebuild a power steering gearbox with details explanation one in a million sir
Thank you for the effort,.. very usefull content❤❤❤ keep educating newbies like me
thanks, very helpful
Great video. Nice job 😎
Excellent video
Cob vulve links what coses
Excellent!
Thank you very much
thank you
I've been a diesel mechanic for 12 years only at dealers and I have only pulled 1 valve out. Thank you very much for explaining this with such a great attitude and delivery. I've just watched found this series and can't wait to finish watching it to finish. I would like to see counter bore cut if there is not a video you have done yet. I find it very interesting seeing the behind the curtain operations of before I get the cylinder head to install on the engine. I've probably put on 50+ cylinder heads. Thank you for your time!
I understand the axles are shown here being locked together, but are the left & right wheels on both axles also being locked to each other like in a normal differential lock? Or is it just normal differential function on both axles, but with equal power each? And if it's the latter, can both methods be combined locking all four wheels together at equal roation?
Sir, I am your subscriber from Indonesia, I want to consult with you, does the worm steer have something called a TORQUE ROD? What is its function actually? Because I have a Worm Steer for an Isuzu Trooper Diesel car where my steer is already heavy and I have replaced the Seal Kit but it is still heavy, the information I got had to be checked on the TORQUE RODS and the TORQUE RODS were modified using a lathe so they are usually lighter Turn the steering wheel of the car. So far this has not been discussed with you. function and use of automotive tubes. ? Thank you, I'm waiting for the answer
I use a valve face scibe. Work very well to transfer to the seat for contact location
I appreciate this video man. Started doing BIT inspections and going for a T8 ASE. This has given me a better understanding than other explanations I've heard. Great job!
Sorry to be pedantic but, you say 'it doesn't matter where the piston is, it's always going to be 100psi'. This doesn't sound right to me. Not only would the pressure change as the piston moved up and down the cylinder but the gauge pressure would change depending on the position of the gauge due to pressure at depth. Perhaps you meant this change would be slight and therefore negligent?
Leaving in the accidental hit was a good move. Great content earned a subscription and a like.
This is really helpful
Need some help with range selector on a super10 leak through both insert valves
Hello, What is the item number for that valve seat puller?
Ok
Great video thanks 👍
Do you grind valves for the general public?
Nah you gotta watch the video and diy. This is TH-cam 😂
Completely unrelated to car engines, but working on a hard seated valve (hydraulics) design. This was very useful. Importantly in my case the "interface angle". Opposed to the whole potential contact surface. Just reaffirmed the direction I was going. Well explained for an engineer.
Powerful info...👌
Thank your effort , its was so helpful to understand the steps to dis . and assembly this part of steering system
Bonjour,où peut-on se procurer l’extracteur de sièges (VALVES) si vous avez une réponse,je vous remercie.
If we removed the drive shaft between two differential truck still able to move ?
Yes but you'll have to activate interaxle lock
@ulrichpatterson61 If don't locked the power divider is not able to move right ?
If we consider diameter of piston. Then we have to calculate area and then multiply divide with force?
Thank you very much. The explanation is very accurate and from a skilled teacher. This type of explanation is not available in TH-cam clips. I repeat my thanks and appreciation to you.
Great vid. Where can I buy the tools to assemble the bearing adjuster and the locknut?
it looks like a Detroit 6V-71 2 valve bus application engine
You are a great teacher thank you
good info
We have a 4 stage cylinder that fully extends reteacts the first stage then dead stops what would cause that
Hello from where you buy this machine I need such a machine for working can you help me to buy
Masterfully done, brilliant explanation and you do make it look easy, especially considering that you use tools that are readily available that do not cost the earth
Thanks for all the videos posted. Very helpful to understand the mechanics of components.
I have a semi that when I put in gear it won’t move till I put in the power divider then it’ll move but just the rear not the front rears will turn. When the power divider is on the drive shaft will just spin from the transmission. Any help?
Sounds like your spider gears are broke and when locked, only turn the heli gear.
Very detailed nice video Thank you
Awesome demo. The preset valve guide installer was nice. Will have a machine shop make one for my requirements 👍
Good day very enlightening video need that information very much i have older eaton 15 speed trans and changed my shifter it was leaking air pretty bad added new 5/32 airlines and new a4688 slave valve been scratching my head the slave valve when i shift to low side it leaks air and at 1st doesnt want switch over to the low side been in shop 2 days and mechanics are not figuring it out So today purchased new air filter / regualtor and watch your video i believe i might be close to the issue had bit of moisture going threw my system and i believe i might need to replace shift range cylinder o rings any insight will be very appreciated also will purchasing new pin and spring and sleeve kit behind the slave valve thanks a million great video new subscriber
It’s amazing how many people don’t know how a differential works. Throw it in as an inter-axle and people lose their minds. Great explanation though!
I think mine is leaking oil between piston housing and transmission
Good informative video
Wow left Sait eh. We need them knowledges
What is the rotation if pressure is in port A?
