73 Honda CB750 Cafe Racer Build Episode 3 - Crankshaft & Main Bearings

[@les5386]

I know this is an old series. I've watched it before, it's a great series. I inherited a basket case '74 CL200 from my father-in-law. This is the first time I've torn a motorcycle engine down to splitting the cases. This series is full of helpful information. Thanks.

[@HackaweekTV]

Cool! Thanks for watching!

[@estebanobish1]

I thank you so much!!! Couldn't ask for a better explanation about the bearing selection! I'm currently working on a 1982 Honda cm450, and this video really was a huge help!! Thnaks!!!!

[@michaelmartin5942]

Like everyone else mentioned, this is great content. I would not have figured this out on my own. Thanks for inspiring me to start the rebuild on my '78 CB750 project.

[@HackaweekTV]

Glad to help!

[@michaelmartin5942]

@@HackaweekTV I noticed that there's a round 3" diameter plug/plate on the lower engine case next to the oil pan. You can see it in your Build Part 15 video at 16:30. I haven't been able to figure out what its purpose is. Any ideas?

[@johnnuttall6112]

That bearing information and explanation has just helped me out so so much YOUR A STAR THANK YOU

Great info. About Bike Bandit, they were one of the first to have the schematics online and did a lot of business because of it . When their competitors came along with the same feature, they had lower prices and also showed the customer the OEM part numbers rather than a proprietary bike bandit part number. Having the OEM part number is the best way to find the cheapest price. The next tip I can give you is that there is a class of part dealers that actually don't have any, or very little parts on hand, they take your order, then they shop around, buy the part from someone else and ship it to you. Ron ayers is one of these. When you use that type of dealer you have to be prepared to wait several weeks. I usually use rocky mountain when I need something quick and I'm willing to pay a little extra for it.

Good advice, any project should have a log book and with digital photography, easy additional documentation. What's that I see, three bikes in the background and a fourth on the floor.....correct priorities. 1st nice day of the year here in Michigan. Sunny and 70. 3" of snow fell last Tuesday.

[@dylanjones678]

dude you just save me so much time on my 85 cb650sc thanks man! Great job keep up the awesome work.

[@fufufufusion]

Hey, I just want to tell you that I'm very glad that I came across your videos. I'm kind of undergoing the same project ('73 Honda CB750 as well) and this is really helping me out since I'm more of a visual learner. This will be my first bike. Keep up the awesome videos. Thanks!

[@yuriyork8094]

Awesome videos. Thank you. I just picked up my 1977 CB750 and I think I'm gonna have to do the same. So watching your videos gives me a pretty good idea how little that I know and how much I still need to learn.

[@keepitrunning]

Bearing can be fun, not always easy to explain on the phone either and I've done a lot of that over the years, now I can refer people to you.

[@iismatthew123]

You saved me so much headache. Thanks!

[@billtaylor4224]

Know what is real fun. I have an early sandcast. Crank is marked with Japanese characters that are about as visible as the planet Saturn without a telescope.

[@iandoesallthethings]

Speaking of colors, don't forget to swap out your power band! The red ones go faster. Edit: Also, this is making my head spin a little. I think I'll wait a while before I try to rebuild an engine...

[@ericpare7091]

I really enjoy your videos, been watching all your Sabre episodes back to back a while ago and this new build look very promising. You should add a direct link to your donation page in every of your episodes, I had to dig a bit to find it :)

[@irishwolfhound1987]

Another amazing video cant wait to see more next week.

[@muh1h1]

can't wait for "next time" :D love your work, best youtube videos of all time, and that comes from a youtube veteran! (i am a VERY active youtube user since 2008, and i spend a few hours daily here) :) Thanks for your work, always brightens my day! :)

[@DeanSegovis]

Thank you!

[@muh1h1]

no, thank YOU! :)

[@cb400fhonda6]

Awesome in all respects Master of 2 wheels

[@Drewshauntedstudio]

I'm so happy you canged your into music... that old sound was annoying as hell :p

[@Fubar12341]

Fantastic information

[@jmc5341]

great videos. these are really going to make my project go smoother. I'm getting ready to start work on a 1972 cb750 I picked up recently with about 6k miles on it. if your still responding to videos this old what's the method for getting the cases so clean?

[@rogerjarrell2121]

Great teacher

[@Randyschmandy]

I love these movies! Will do another 10$ donation on every 10 episodes. Not much, but keep 'em coming! :D

[@DeanSegovis]

Thanks! :)

[@s.y.b.1046]

very wel explain ! that is awesome :) thank you for making those ! helps a lots

[@billtaylor4224]

My bike is a total basket case that was disassembled many year ago. The box has multiple crank and rods along with a pile of rod and crank bearings. I believe the bearings with a groove in them are crank and the smooth bearings are rod???

[@marioortiz8853]

14:29 THESE NUTS!!!

[@billtaylor4224]

Question. Does this system for sizing bearing still work if the crank is not original to the engine or the rods original to the crank?

[@gabrielbouchard3669]

if i buy a completly desassembly engine(for parts) ,how i can the find the right colours of my connecting rods if they are loose in the other box? real problem

[@corollarollas]

Awesome information. Great vids.

[@theinterworks]

This is awesome!

[@Flo-degro]

This is great.

[@bwtegu7135]

If i follow your video in regards to reading my crankcase and crankshaft on my cb550 for letters a numbers, the same bearing coding/matching would apply correct?

[@route90]

Hi there, its been a while since you made this vid, but im hopin you can answer a question for me. I have a cb750F 1980, and im rebuilding the engine. the connecting rod bolts for my bike are now discontinued and since you used a 'later' connecting rod bolt, is the reverse the same? There seems to be the 73' connecting rod bolts still available.

[@stevenlamphear1945]

The wider the pressed plastigauge, the narrower the oil gap. Are you sure which end of wear spectrum you are measuring? Was rotating assembly supported? Or put plastigauge on both sides of bearing and average the widths !

[@ivogiev]

Can I ask maybe a stupid question, cause all my engines have never been done by me so far? How do you remove the plastic gauge off of the new bearing shell after tightening it without scratching the bearing surface? Same goes for the crank journals. Maybe it is easy to come off , don't know - that is why I am asking. Another question is - choosing colours for bearings - how did you know which 5 on crank letters were for main and which 5 letters on crank were for connecting rods? Maybe the "P"and "J" symbols?

[@ChewbacaTW]

Just out of curiosity, would you say that those Torque-to-yield bolts are ok to throw in the bucket-o-bolts, or should they just go in the scrap bin?

[@bryanfergusonsingersongwri4505]

so, I have a 77 hondamatic, 750 cb, looking on the bottom of the case, cannot find any letters to relate to bearing size, should they be there?

[@harvestwendigogaming5947]

A friend and I are rebuilding a '72 CB750k and there looks like a port window next to the starter wheel. Newb question, is that supposed to be there without a plug or is there a plug for it?

[@rogerjarrell2121]

Wondering if there is a thrust bearing measurement for the crank ?

[@alexaparicio1492]

I have a 90.000 mile cb450. The rod bearing have 0,05 The Standar is 0,02 And The service limit is 0,08. Do you think I should replace them?

[@jarydt1152]

so hard to find the right rod bearings for my gl1100 anyone know where i can find yellow 1&3 rod bearings for a 1982 gl1100 goldwing

[@minbannister3625]

i was going to buy one of these, not now.

[@MrTolgig]

kinda missing the old intro :)

[@DeanSegovis]

You can always watch an old video... :)

[@BillyTzENDURO]

Finally! :D

[@andrejones4857]

[@idan1210]

24:07 is that a crack in your case I hope not

[@ferrari430sc100]

2:20 ... i got a question.......................... . . . . . . . . . . . . . WHAT ARE THOOOOOOSSSSEEEEEEEEE :')

[@jacobkjrchristensen8879]

Thansk.....autocorrect

[@r6stu]

The wife wants to know where shamus is? :)

[@DeanSegovis]

He's right here on my desk. :) He'll be in a video soon...

[@jhbass]

Any idea where I might find that shop manual? Thanks!

[@jakewagner5473]

I have the same question ... Were you able to locate one? I'm not having any luck on the innerwebs!

[@jhbass]

Jake Wagner Nope. :/

[@jakewagner5473]

Thx for the reply James ... I have only located a 1970 sand case shop manual, and they want $200 !!

[@Mytwistedvoices]

The green book is a reproduction. I found the original, if you want it I can help.

[@karlvanboxel561]

Mate u really should have all your crank brgs in at the same time ( new ones and torqued your crankcase bolts to the right spec invthe right order also NO movement when checking the rod brgs with plastigage! 😢 what i do is atatch a piston to the small end ( no rings) and slide the barrel down and tighten the barrel down with a few pipe spacers and washers and nuts this hold the piston and rod frim moving and fucking your plastigage measurenent also need to torque the rod bolts best o luck

[@alexaparicio1492]

90.000 km. Sorry. Best regards.

[@JMD006]

3 Capítulos y no ha podido armar el motor solo habla y habla y ya lo abre y ya lo cierra el motor sin hacerle nada. Es desesperante.

[@stevenlamphear1945]

.001 thousandth on a rod bearing is out of spec....too tight!

[@robertbrandywine]

That book he is looking at only shows the measured existing clearance, right? What should the clearance be in thousandths of an inch?
