Install Caterpillar 3406B Rear Main Seal And Flywheel. Transmission Rebuild Part 8

[@maxpuppy96]

Bolting that flywheel on is a workout.

[@hughstephenson2957]

Note to all....ALL mechanics (hobby and otherwise) when you pick up your parts.. ALWAYS.... ALWAYS look on the PART to assure it is CORRECT!!! DO NOT just LOOK AT THE BOX and say "ok..that's the right one.. ESPECIALLY in these days of on line parts ordering!!! Steve is absolutely correct to assure the number ON THE PART is correct.. One number has cost me 2 days and 1200 miles of driving to get the right part. Lesson over!!!

[@DNR5586]

These past two episodes took me back to a diesel mechanics shop class I took in high school. Our teacher reminded me of you, a no nonsense type of guy. I really enjoyed that class, great videos.

[@charlestringale772]

Great video. You taught me alot. You teach very thorough. And illustrated everything perfectly , where I could do it myself with confidence. Thank you.

[@rickbartram7114]

Next time Steve put a 3/8 coarse bolt in timing hole in fly wheel ,just above starter also good for valve setting ,more accurate.

[@gregorylynch3540]

Ratchet strap to hold the flywheel from moving 👍👍 I’ll be using that idea this weekend

[@kimmorrison9169]

yeah that was slick wasnt it!

[@Cap6302]

Steve, You should have been a shop teacher!! Excellent walkthru.

[@seansclassoictrucks]

your working smarter and not harder, I manhandled the flywheel on my 1693!

[@stevenlewis6060]

I always like to see repairs done by the book.unfortunatly if you don't have the skill required or a shop to facilitate proper repairs you are left with taking the tractor to a dealer or relying on shops that think a hammer is the olny tool you need to install seals.great job steve.

[@hughstephenson2957]

Yeah well, that pilot bearing and rear seal are two things ya don't wanna be doing on a regular basis..trust me on thatn

[@charlestringale772]

Hi. This is exactly why I looked up rear main seal installs. My mechanic showed me today. There's a leak coming from in back of flywheel. And he installed a new rear main seal. So now. I need to have him remove flywheel to see if it is his screw up. Did he use right seal. Did he use compression tool or a hammer. This sucks. ..now alll of a sudden the intercooler is leaking. I'm like what's happening here. Wow. I'm not happy. Monday will be not a good day. Thanks for your tread. Cheers

[@billvose7360]

Steve, I fully understand buying the special tools. I do the same with my vehicles, not as big or HD as yours, just a 7.5L 1986 F350.

[@davidschabel4664]

This is a great how to get all the right parts, then installed properly, good job, maybe you will inspire others to save money, pull toy here.

LOOKS like I am NOT the only one up with the OWLS ☺️ HAVE done everything you are doing on a passenger car/truck level at one time or another... UR Toys are much bigger and heavier ☺️

Really enjoying watching you fix him 😁👍

He's a boy, Peterbilt built the truck in 1984 and Orwell wrote the book, don't forget it, that's why it's called Orwell.

[@RMTTR640]

I have used extra cutoff push rod.....5/8 fine from 30/30 spring brake cans as guide pins/ studs ....works very nice and supports the weight of the flywheel

[@philheese1728]

Exactly what I was gonna say. Line-up studs are your friend. I have all sizes of them from doing Cat transmissions.

[@fsctrucking]

I will remember that next time I cut a push rod off of a brake chamber. Thanks for that.

[@robertbradford7892]

The engineers got it right for once that seal installer is sweet!👌

[@scarlett-walker4908]

Hi Steve.. you need to open a Semi truck mechanic shop...i know alot of people will come to your shop ...you do know your stuff about trucks..

[@kimmorrison9169]

Oh BTW, you have a nice shop to park and work in as well as the tools you accumulated over the years

[@davebullock3517]

You were doing such a nice job, and then you used a crescent (adjustable) wrench to install the crankshaft seal. I realize they double as a hammer, but a 1/2 drive ratchet is much nice to use. 😊 Nicely done video. 👍

@@michelchartrand7257 😂

[@tomball7681]

Good stuff hope it all works out for you!

[@MagentaRV]

I'm guessing those holes are to let air in and out as you compress and remove the tool. Don't forget it's a seal - it'd be like a compressor without air holes.

[@hughstephenson2957]

HOLY CHIT!! I paid $10 for one of those seal tools at an auction (actually it was in a "goody box")..

[@peteriannucci6108]

Fsc thanks you saved my butt cat gave me rear seal not front. I have install tool but not marked front or rear I believe the taller one is rear when laid flat on table ? Thanks again

[@edreeder9853]

A lot of advantages to a cabover, What i learned to drive in 60 years ago.......

[@sfcjones2590]

On my Duramax they use a flywheel tool that goes where the starter is located. Locks it down good.

[@martincordell6676]

Thanks 😊. A Blessing!!!

[@brendajanes4139]

Hi Steve, I love watching your videos, especially the whole ordeal about Orwell breaking down and rescuing him. I have noticed that a few of your past videos do not have subtitles which makes it hard for me to understand. It could just be my end though.

[@jonnyonwheels]

I am jealous of your shop press! I had found a similar one on marketplace but missed it by that 🤏🏼 much. 🤦🏻‍♂️

[@arthurbolton8477]

a bit of oil on that seal would not go amiss .and the seal tool.

[@yoyito17]

Thanks 🙏

[@raywilson800]

Hey, that old rusty, crusty press was built by some of them Wilson's. Hell you know it's got to be good! Like my Hero! I bet your arms were tired after wrestling that flywheel and big torque wrench up in front of you. Great video.....as always. Later!

[@zeeshan_engineering_services]

Well I mostly prefer new modified 142-5868 rear seal group for Caterpillar 3400 series, C15, C16, C18, 3406E and Perkins 2500 / 2800 series engines rather than that 2 piece version😊

[@arthurbolton8477]

did you loctite the flywheel bolts.

[@042452]

Looks like you needed to do the starter while it was apart

[@kimmorrison9169]

interesting install of rear main seal and flywheel. I saw you used no locktite on the flywheel bolts. That seal install tool was slick but damn it wasn’t cheap was it. Next video is the clutch going in then that new tranny?

[@DavidLeslie65]

One of your better videos nice to see someone else that understands how to use both service and parts book. You should check out squatch 253 channel he is also a believer of getting the correct tool or building one if unavailable.

[@here-i-am2316]

and the correct torque

[@ronfullerton3162]

Building your own tools is a fun challenge. Very rewarding when you succeed.

[@jman69922]

cool

[@aintskairtolskol9520]

hey bro next time run a bolt threw the bell housing and pin your flywheel,inspection hole is in bell housing

[@philipmichel215]

Doing it yourself, at least as much as YOU can makes one feel better about the outcome

[@hughstephenson2957]

Hey Steve, doesn't Cat still have the "Renta tool" program where you can rent things like that seal press? Maybe it was Detroit, I don't remember..lol

[@rjptrucking4598]

Where did you get your manuals?

[@firstcomment2801]

Don't Locktite the spark plugs.

[@timclarke9346]

As for the torque on the fly wheel...I would of torqued all to 100 first then 200...that's the mechanic life....

[@arneservatius8686]

I was born in 46. I remember when your press came out in 47😁

[@garrettthompson8314]

Great video

[@kw900lkevin]

you know on the front side of the flywheel housing on the passenger side of the engine is a hole to put a 3/8 bolt or pin the flywheel to (hold) the engine from turning while torqueing those bolt or other service work on engine

[@fsctrucking]

Yup, the timing holes

[@amossnowdaharleyman9179]

Old press: I'll give you $1000.00 for it right now. But you won't sell it lol. I like my old stuff too. Have a 1930's Marvel draw cut power hack saw with the original motor that cuts true.Paid $20.00 for it. Also have a 100 year old gear oil tank and pump with working meter.Found it in a falling down barn on some property I bought.Wouldn't take anything for either.

[@fsctrucking]

KR Wilson will take them and restore them for a charge. I find them easy enough to fix. You are correct, it's not for sale. :)

That flywheel is probally 60lbs at least and try manhandling it is a recipe for injury good job on using a lift for it As for the press was sure it was an ice cream machine 😆 i think anyone on the internet has seen what hydraulic presses can do when used for entertainment

[@hughstephenson2957]

When I was in school I couldn't go to the gym like kids do nowadays (I was a farm kid and town didn't have a set of weights anyway) so I started making my own. As I got better a flywheel out of a Detroit (I think it was) was my bench press weight..

[@youtubeisawesome2487]

front seals have a red sealing area for the cover seal area paint, always fear red in the rear, they dont even sell this seal anymore, its a one piece seal for front and rear now (both are green in color), thumbnail is always get the right tools, proceeds to use a cresent wrench,

[@hughstephenson2957]

When that's all ya got and the correct wrench probably cost 3-4 HUNNERT dollars.. yah. There are uses for Crescent wrenches..
