Can you please do a video on greasing the truck? Great video by the way!

[@jerm33291]

Great video. It's good to show the guys that have never seen this done how east it really is.

[@ralphwood8818]

Was driving a new truck with a Cummins engine once years ago. It developed a loud screaming noise. The boss said you are near a Cummins dealer. Tell them to check it out and change the oil. A large hose clamp was in the turbo. I looked under the truck before I climbed in The drain plug was hanging by about 1 thread. Luckily the plug was at the front where it was easy to see.

[@mastercris026]

Drivers should know what thier driving

[@mastercris026]

Doesn’t hurt to look under and check

[@That_one-guy192]

Watch the Oring seat before you screw her down is a dang good tip all around anytime you’re messin with top load filters. I screwed that up once on one of the Mack Centrimax filters and painted that pretty red engine black. Boss man wasn’t too happy about it.

[@KoonTrucking]

Harland Gambill haha I always say the hard earned lessons are the one you never forget !

[@Toolaholic7]

I have see them loose installed by someone else.Complaint is a oil leak and the fix is simple,tighten it up by hand only.Make sure the gasket from the old oil filter is not stuck to the block too.I have done it and caught it in time,forgot to check for this wondering why it was not tightening up.

[@seeking70]

Came for the instruction, stayed for the jokes.

[@andresisaza6096]

Hahaha 8:55 “ I promise you it ain’t not falling further than that”..!!

[@chrischiampo7647]

Nice Work Clay & Wild Bill the Jokes n Commentary Cracked me Up 😎😝

[@juanhinojosa6272]

Well that seems simple enough. Punching a hole on the bottom of the filter, nice saves on cleanup👍

[@craigthomas4999]

I wonder if junkie saw this and learned to punch the filter 😂 oil change 101 👍 great how to video

[@Alanthe918mobilemechanic]

I work on medium duty Isuzu box trucks and on those fuel filters like the one you showed on the driver side I usually have to pull vacuum on it otherwise you can prime it all day long but that truck will never start

[@cliftondonald7692]

Great video straight to the point

[@FirstGendodgegarage]

You got to eat your Wheaties watching you struggle with the oil pan bolt was pretty funny

[@ryanpokhan5257]

Really good video..watched from the start to the end..I have a d13 volvo🤣

[@PoBoy_Trucker]

Great video brother

[@gbengajohnson282]

Nice video really not boring

[@farmgineering3259]

Great commentary!

[@patriotarborist711]

I have a '07 F750 with a 5.9 cummins. The fuel filter is a can type. Do you know how often I should replace it? Thanks!

[@louisianabrokenenglish]

I love it … “man in the hole” 🕳 she starts right up !

[@Praiseinspirit]

How many gallons of oil does a 1987 350 big cam engine hold? I lost the dipstick so I pulled another one off of my parts truck and need to see where the oil sets so I can mark the new dipstick.

[@edyramirez9683]

"they say dry rubbers can hurt" 🤣

[@mastercris026]

You don’t have to put oil in the oil filter because it can actually overfill and cause damage if you put more the 44 qt

[@guacamoleweiner69]

You won't overfill if you put oil in the filter if you put the amount of oil you need to.

[@chopchoppancake86]

Why I like your accent boy!

[@Pete-from-Tn]

Guy had that bottom O-ring sucking air a few weeks ago. He was 100% sure it was right. LOL after checking it. found out it had rolled and was the issue.

[@KoonTrucking]

Pete k probably got in too big of a hurry. Sometimes slowing down is the fastest way to get a job done. Old guy once told me “slow is smooth and smooth is fast” took me a long time to figure out what he was talking about. Prime example right there

[@MrJobforacowboy00]

My theory is the oil plugs tighten on their own some how. We have a couple cat motors and they have 1 1/2 drain plug. I've serviced the same truck twice in a row, I was the only one to touch the drain plug and that son bitch was tight as hell had to use the ez red 3/4 drive extended ratchet. The one that's 3 foot long lol. And I know I put it on "hand tight" last service lol

[@KoonTrucking]

I agree. I know those speedco guys are pretty bad about over tightening them. Every time we get a truck like that I ask them who did it last time 90% of the time it was speedco the other 10% TA ! Haha

[@edwardrivera2844]

So no prime pump in the Cummins? Wow that’s easy 👍🏼

[@markiefufu]

Some, if not all Cummins 8.3 engines are self priming. At least my 98 mechanical engine is.

[@rogercoffman6472]

Who ever tighten that oil pan bolt on there must of been fighting with the old lady that day

[@scottpearsontoolsmore185]

Great video thanks brother. I really don't miss do that. I really don't miss doing them when hydraulic filters are involved. Keep up the great work see you in the next video thanks again brother.

[@jamalt7461]

Great and easy to follow. 👍👍👍

[@jhowie949]

Man clay this is one of the funniest videos I’ve seen you do in a while from you . Yes this is a new subscriber for you but I’ve been subscribed to you on My other Jesse Scott channel I’m trying to have a channel just for Tools wrenching and other vehicle related stuff

[@KoonTrucking]

J Howie well thanks for the kind words and also subbing from that channel also ! I appreciate the view and the comment. Thanks again.

[@jamesholman7702]

Great video , great instructions to follow , it's hard to do maintenance or repairs depending how big or small the maintenance or repair is if I may ask ??

[@KoonTrucking]

not following the question? sorry

[@dandosreis1541]

After whacking myself in the head more then once . I bought a 36" breaker bar off the truck . Snake it between the frame and the leaf spring and you crack the drain plug loose . Don't even have to roll under the truck .

[@alansmith3447]

Hey, I have an old truck with a cummins M11, has not run in 3 years. Ran when parked and has less than 100k miles since new. How extensive a service do you think it would require to get tit to fire? Would this be fresh fluids or would I be looking at injectors, fuel system probs?

[@tti4919]

What tools to change oil filter??

[@deanh7190]

A strap wrench works best.

[@johnny7121]

felt like I was watching a stand up show.

[@KoonTrucking]

Good or bad?

[@roz4747]

Air line from the compressor was bad? Replaced the whole length?

[@CLSC-cg6li]

Great video Anyone can tell me what kind of grade oil to use on differentials I wanted to do the service myself I have a 2009 peterbilt 386

[@greggoble5580]

Wait a second. How you get that oil filter loose? Didnt show how long or much crap to get it loose being you all had to use a breaker to loose the drain screw. Filter had to be tight

[@ronanderson1816]

thank you!

[@shrek22]

I'm assuming biodiesel won't mesh well with the fuel filter seals and casing.

[@Son0fLib3rty]

Hey yall i got a 2001 cummins ISM. The oil starts out at 65 psi then drops into the teens after warming up and it drops at the filter head Ive ruled out pump, guage, leaks, injectors, jakes while everything on the valve train looks good. I had a 12 hour diagnostic that ensured the internals had normal ware. I recently had the injectors in cylinder 2 replaced as well as a rocker arm on the same cylinder replaced. I used the truck for two days and had to bring it back to the same shop. The mechanic informed me that there was a wire broken on the number 2 jake assembly. And now insists that it wasnt from the work they did but dosent know whats wrong with it please any suggestions will be greatly appreciated

[@blazebox71]

Whats the point of punching the oil filter besides the fact that you dont gotta worry about tipping it and spilling oil or it draining out around the filter when you take it off?

[@KoonTrucking]

Blaze Box that is the point ! If you have never dumped a full oil filter because you bumped it trying to get it out or dropped one ...... well you have really missed living because it is so FUN ! Haha just saves a mess later on

[@dieseldoctor9294]

Blaze Box that's it, you don't make a mess when it's not full of old oil taking it off, plus it's not as heavy!

[@blazebox71]

Yea i pretty much figured that was the reason i dont have the time at my work to punch every oil filter i do so i either live with the mess if i happen to drop one or most of the time now i dont have a problem holding on to em lol

[@linaday7966]

Hello today I was trying to find video instruction for emptying the hydraulic fluid reservoir for a Cummins engine in a Case 1845c skidder to no avail. Is this anything you do?

[@soillife1]

Pump it out.

[@johnepperson1162]

Hey guys enjoy the videos, but what oil filter wrench do you use? I have a isx in a 2015 Pete 579 real pain breaking oil filter lose. Any ideas?

[@kurnal707]

He you probably won't read this but on those upright Davco filter housings you should really clean out with some brake cleaner. This cheap and nasty bio fuel that truck stops have gunks up inside the housing.

[@KoonTrucking]

I read all the comments ! We usually clean them out but not with brake cleaner, it’s too rough on that plastic and will cause it to crack over time.

[@johnnyboy1543]

Is this the isb or isc ?

[@Julian-gh6fn]

Oooohhhkaaay

[@Saladon89]

is this the big cam 400 cummins?

[@David-ho7nt]

LMAO, I work at a loves Speedco. But I do know how to torque an oil plug.

[@theblackschwab3561]

Ive lost ALOT of money messing with you guys.

[@David-ho7nt]

@@theblackschwab3561 Sorry you've had a problem with us. Not sure if you've been to my store or just in general. I have good mechanics at my location.

[@smokey8721]

Do you have a video of running an isx overhead

[@KoonTrucking]

No but we can do one !

[@KoonTrucking]

Just never thought of doing one to be honest with you but that is going on the list

[@kingparis24]

Do y’all adjust the clutch during that time too?

[@KoonTrucking]

Not on a regular service no. Only when needed.

[@manuelsalgado8510]

I removed my fuel filter and can’t get the new one back on. The old one came out easily but I can’t line the new one with the threads, any thoughts?

[@renegadorivers4031]

What type of filter is it ? I can help you

[@manuelsalgado8510]

@@renegadorivers4031 i got the filter on after 2 days , thanks for replying

[@Alanthe918mobilemechanic]

Why do u put oil in the middle of the filter i thought it was only good to do on the sides in the holes

[@KoonTrucking]

It still wicks to soak the paper inside. People scream that all day long but it still wicks to keep from taking oil as long to go through.

[@Alanthe918mobilemechanic]

@@KoonTrucking makes sense thanks for responding clay I appreciate that a lot love your Chanel man I was in a bad place when I got out of rehab and this Chanel is what I use at night now before bed gonna go to diesel tech school just for the tool discount lol thank to y’all making me fein for tools ⚒️

[@markiefufu]

I thought it was the fuel filter that you only pour in the holes along the outside and avoid the center hole. I've already filled every hole on oil filters.

[@davidwalle5025]

Mr clay and wild bill great video can you do a video on servicing a cat ?

[@KoonTrucking]

I would if we had a CAT but we don’t have any in our fleet and there’s very few left around our area that we service for the public

[@USclasSICK]

Hit the hole.. you ever have that problem bill .... turn the lights and I dont .... lamo!!

[@DonziGT230]

7:05, that was not half a turn, it was less than 1/4 turn.

[@davidbundy1769]

Shouldn't pre fill the oil filter, you are sending unfiltered oil through the system.

[@KoonTrucking]

Think new oil needs to be filtered?

...the clouds will be jealous.

[@bobmay9887]

It says 3/4 turn on the filter just saying yall

[@WTFxCROWEx]

All those Snap-on tools and you use a harbor freight ratchet to bust the drain plug

[@KoonTrucking]

David Crowe first off it wasn’t my ratchet I was just helping the guys in shop that day. Second with the cheater pipe I wouldn’t do that to my extra long 1/2” drive ratchet either. $265 ratchet there ain’t no cheater going on my handle.

[@ericmesa6050]

why use a harbor freight ratchet

[@tjtrent2351]

“Hey, Diddle Diddle, fuckin timing in the middle!” Good ole Hptp sons of bitches getting techs all the riches.

[@67697072]

Don't let your Snap on guy see ya using a cheater bar on that ratchet......warranty VOID !!!!!

[@w0wnoothernames]

He used it to take it off, not tighten 🤥

[@Arlecchino_802]

8:51 😂

[@tti4919]

No deetails

[@KoonTrucking]

you seen it step by step not sure if you need a play by play when you watch it happen ?

[@EPTEHAX]

unscrewing the drain plug on the side of the oil pan leaves another 1 gallon of dirty oil inside. first mistake! the second mistake is that if you tighten the drain plug with such an effort, the thread will soon be broken. seeing so much lack of professionalism, I did not look further.

[@jameswilliams9983]

Don’t go to the Speedco.

[@mastercris026]

Get a longer ratchet

[@jameshood3692]

By the way thae davco is a primary not secondary the secondary is on the engine

[@Ever443]

Apparently the same gorilla tightened the drain plug that puts new filters on diesel trucks from the factory.

[@tone-e2toes759]

Ever run Into an oil filter that won't come off after punching a hole through it? Or a lift pump that fails to prime? A lot of fun.

[@KoonTrucking]

We always break them loose before punching the filters. Been there done that and didn’t even get a t shirt ! Lessons learned the hard way always seem to stick around the longest.

[@Alanthe918mobilemechanic]

I don’t put the drain plug back on until the new oil filter is on cause oil will come out the pan once u drop the filter not always but sometimes it will so I usually do filter first then drain plug

[@jimmyfumbanks6081]

That's the easy part . The chasis needs grease and whatever else. It's hard to find a video about that.

[@KoonTrucking]

Pretty simple: 1.Look for grease fittings 2. Put grease gun on those grease fittings 3. Pump grease gun 4. Wipe off grease fittings. Done.

[@LavenderSystem69]

Say I wanted to use a pump instead of crawling up under there to pop the drain plug... whereabouts would I go sticking the intake hose from the pump?

[@jdw37jr97]

Thx guys!!!

[@dickysnader3264]

good job Bill n Clay

[@rhess10]

Using the punch in the oil filter, is a great tip. Thank you.

[@upnorth5465]

I do the same thing but use a 18" alignment bar that I ground down to a point. Comes in more handy when they are more recessed as well. Old timers like to give you shit but I don't care. They can continue to fill their armpit with nasty diesel oil. Or better yet drop a full filter on their face and make a huge mess.

[@memopat1]

For our freinds at speedco the torque on the oil drain plug is 59 foot pouds/80 n.m. lol

[@KoonTrucking]

memopat1 I think they are hitting about 159 ft lbs ! Haha that was unbelievably to tight ! As you seen I had a long handle 1/2” ratchet and still had to put a cheater pipe on it.

[@7119ricky]

Actually no the torque is 35 foot pounds on a isx
