Honda DOHC Engine Removal

If you have never removed the engine from one of the early 80's Honda DOHC inline fours, you will have no reservations about doing it yourself after watching my video. A minimum number of tools are needed and if you have a motorcycle jack, you're in business.
Note that the bike I'm working on in this video is an '83 CB1100F. The procedure is identical for the 1981 and 1982 CB900F. The CB750 engine is not rubber mounted in the frame like the other models, but the overall procedure is very similar.
I hope you enjoy this video and find it helpful. Thanks for watching!

Tom, this is great stuff. Thanks so much for taking the time to do the video. Lighting and such were excellent. Folks may not realize the challenges with the video part - beyond that of the task you are demonstrating. A couple of items of note: You'll still want to use the service manual. Tom mentioned carbs, airbox, etc, but you'll also need to remove the chain/sprocket from the left side. That means loosening the rear wheel axle and rotating the chain adjusters to create chain slack. You also need to remove the gearshift lever and the drive sprocket cover. He also removed the right side brake pedal and the mount to which it connects prior to the start of the video. That enables you to remove the subframe assembly. All easy stuff. The key is the adapter plate to enable your jack to securely support the engine and make engine removal safe and easy. Thanks again Tom!

Thanks Chuck - thanks for the good words. Believe it or not, I didn't use any special lighting and just shot it with an inexpensive camcorder set up on a tripod. I just made sure that things looked clear and relatively easy to see.

[@motorsonny]

Can you tell me what kind of adapter you need to fixate where exactly?

[@SidecarBob]

Good to see you back.

[@tomscyclerecycling8242]

Thanks Bob. I've been wanting to get back to making videos for quite some time. Finally!

[@jgoopra]

It's fun seeing RMI, RMII, and RMIII all in the same place! Great video.

[@tomscyclerecycling8242]

Thanks Jacob!

[@Metalhead55Ish]

Thank you, this is by far the best video I’ve come upon. I’m currently restoring a Cb900f.

[@tomscyclerecycling8242]

Thanks Nestor - I'm glad I could help. You should join the CB1100F.net forum - there are lots of 900F owners there and it's a great knowledge base.

[@chuniquepaceno470]

Thanks for this video. While I hope I won't have to remove the engine, I'm preparing for the worse and this video was the best I've found for a one-person job...now if only I could find that adapter plate to bolt to the bike jack I have yet to buy.

[@persistencewins]

Its so cool to see ya back in action, especially working on 83 cb1100f, one just like mine. thank u

[@AndrewTheCelt]

I am so glad I ran across you I have a cb1100f that I need to restore this is awesome

[@teninchrichard4016]

Look at your creation behind you...LOVE IT.

[@ChrisR57]

Nice video Tom, you make it look so easy. Loved the into and outro music too, thumbs up to Joey!

[@tomscyclerecycling8242]

Thanks Chris. I'll pass on your praise to Joey. Glad you liked the video too!

[@motorsonny]

Hey there I'm about to do the same as I have to rework the engine. I'll be making the same sort of support. Thanks a lot of the clear ideo this actually has been the best video I have found. I also run a channel where I am sharing all things abou tthe CB750f as I record my journey from rookie to hopefully a well all round mechanic one day. Thank you again for making this video !

[@tomscyclerecycling8242]

You're very welcome and thanks for the kind words!

[@motorsonny]

what kind of pens did you use for the tool to support the engine? @@tomscyclerecycling8242

[@buddyv3457]

Hi Tom, Yes, good to see you, and thank you for sharing this procedure, very helpful...

[@tomscyclerecycling8242]

Thanks Buddy. It was a fun video to make. I'll follow up with an installation video when the bike is ready for the motor to go back in.

[@AndrewTheCelt]

Thank you I have a cb1100f that I’m restoring and so this is going to be so helpful

[@bobcannon5217]

Is Tom trying to get me to work on my motorcycles again? Yes, yes he is

[@pauljones9259]

Nice video - thanks for shooting and sharing.....I just removed my CB1100f engine single without help, I used a jack very similar to the one you used but with some 4x2's and ratchet straps, would have been good to have made a fixture like you have, that keeps it nice and secure

[@tomscyclerecycling8242]

Thanks Paul. If you aren't a member of the CB1100F.net forum, you should join. There are lots of great members and and a great knowledge base there.

[@Coolhand99au]

Thanks Mate nice video That is a lot easier than a 1996 Honda CB Seven Fifty F2 RC42 they don't have the removable lower frame which makes it really tight pulling the whole motor out For me. If I'm going to remove a 1996 motor I'll take the rockers and cams off first

[@tomscyclerecycling8242]

Glad you enjoyed it. Thanks!

[@teninchrichard4016]

Beautiful tom..thank you..I'm. A restomod guy 100%, modern advances are a good thing.

[@tomscyclerecycling8242]

Thanks Mark!

[@kennethhernandez963]

More videos please!! I’m building a 900f and lack videos I can watch for my bike

[@tomscyclerecycling8242]

More are coming, Kenneth. Subscribe to my channel and you'll be notified when I release the next one.

[@luvtheus]

Thanks for the great video Tom. I believe I am looking at an engine removal on my 83 1100F. The Primary dampers seem to be getting brittle and are making the familiar "clunking" noise. Wish there were an easier way to replace them other than splitting the cases. Honestly, I dread the thought.....

[@tomscyclerecycling8242]

Glad you found my video helpful, John. I know how you feel as it's a daunting task. Take advantage of the situation and address anything else that looks questionable while you're in there. Best of luck!

[@Galatiotis]

Amazing Video and Brilliant Idea!!!!

[@arealcanadian7448]

Great video thank you exactly what I was looking for

[@ouimetco]

Looks like you have a few of them. I just purchased one here last month. 19,000 miles on it. Could you share some contacts for parts perhaps? I’m on the west coast.

[@tomscyclerecycling8242]

Send me an email to [e-mail] and I'll point you in the right direction. I also have a lot of parts and offer a number of services to aid in restoring these.

[@jcampbell6484]

Hi Tom, great video. I am about to do a restomod on my 81 900f. Where did you get the jig attached to your motorcycle lift? Looked like a great way of getting that engine out.

[@tomscyclerecycling8242]

Hi J - thanks! I got the idea from a friend who had one and just gave a drawing to my local welder who made one for me. I've used it many times and it's perfect for this job. Contact me through my web site and I can send you the dimensions.

[@adamdowning9444]

Hi, Great video! any way you can attach / post a copy of the drawing you used to make the jig? i’m pulling out a 900f SC09 motor out and having a jig like that would be awesome! 😎

[@teninchrichard4016]

Mr Tom..and I know your last name please continue with these vids, I need your support, I have a 900f that is my dream to restomod..USD forks, and 110f swingarm or ZRX swingarm..

[@teninchrichard4016]

Jave you heard of JES built, on fb? He offers a lot of parts for structural rigidity...Just an outstanding guy..racers do what racers do..cj bonura is a client i believe.

[@tomscyclerecycling8242]

Hi Mark. Jim Sawtell of JES Built is the guy who mods my swingarms for me. The one on that red bike was done by him. I just got another one done by him for my client's build.

[@teninchrichard4016]

I habe tje plans via email...thank you, ive had thém for a while, but life pulls you in funny ways I can't wait to use your design..

[@andrewmcmahan9782]

Hey Tom where did you get that adaptor plate for you lift? Thanks

[@tomscyclerecycling8242]

Hi Andrew. I had my welder make that for me. Email me and I'll send you a drawing with dimensions.

[@paulvaultguy]

What about a shaft drive bike? I've got a cb1000C to pull, I'm down to the shaft drive, any tips on how that come apart?

[@tomscyclerecycling8242]

Sorry, I've never worked on a 1000C, so I don't have any words of advice for you.

[@paulvaultguy]

@@tomscyclerecycling8242 well i think it's the same as a cb900c but i'll keep looking

[@noreasterblastworx1076]

Where do you get engine mount for jack?

[@tomscyclerecycling8242]

I copied the design that someone I knew came up with. It's quite simple and I can get you the dimensions. Just contact me at my email address, [e-mail].
