The BEST Way To Install a Honda CB750 Engine Into a Frame | CB750 SOHC Cafe Racer Project Bike | 22
In this video with the help of my family I put the engine back into the frame of my CB750 SOHC Cafe Racer project bike. It is a very heavy engine, and only just fits into the frame.
The wisdom seems to be that it is best to fit the frame around the engine, with it on the floor. This would be because the frame is a lot lighter to move around. Never wanting to make things easy, I have built up the frame into a full rolling chassis, so the weight advantage wasn’t quite as much in our favour.
I realised that even when you are fitting the frame to the engine it will only go in from the left hand side. There are two removable bracket on that side, but even with these removed the engine doesn’t just slip in.
It took both my son and I to manhandle the frame with my lady wife helping to finesse it into the frame. Because it wasn’t just a bare frame, it did take a little more grunting and groaning than we had hoped.
Luckily, the engine went in quite well in the end, and there was very little damage done. The exhaust studs did take a little paint off one of the downtubes, but it should be reasonably easy to fix.

    Did the same on my 750K4 years many years ago. Slit some clear plastic tubing for frame protection, and fabricated a pair of lifting bars. Long time ago, but I think the front bar was secured at both sides, and the rear located into the right side of the engine lug only, so to allow securing the back of the engine first, with a jack under the sump taking the weight so I could unbolt the front bar and ease the front down into alignment. It all went surprisingly well, especially as my glamourous assistant in her pink fluffy slippers, weighed considerably less than engine..

    In hind sight, maybe the 2 by 4 method might have been the one for this time, with the rolling chassis having been built up. But the engine on the ground would be a lot easier with a bare frame. It is all part of life's rich tapestry.

    Was this originally an F model? I saw the oil tank and assumed K7 or K8 but then you said the engine mounting bracket was only on the right. K7/K8 has brackets on both sides. What sort of sorcery is happening here? At any rate, you guys do some serious quality work. I could swear this was a new bike.

My stone chip and rust protection still good on it so it pays to put in the work . One random question what do you think about your car creeper never got one myself Kev East Devon 👍👍

  • @SPANNERRASH

    11 ай бұрын

    Hi Kev, that bodes very well for the work we've done on the BMW E30 project then! It was a bloody unpleasant job getting underseal on. Ahh the creeper is a brilliant idea, but there are a few things to watch out for. I'd get a higher-quality one next time. If you get one with cheap small wheels, it won't like to roll on a floor with any imperfections to its surface once you're on it. While it's handy that ours can double as a stool, due to the design, it doesn't hold you as low to the ground when you're on it flat, so if you're working under axel stands you can find you're not as low to the ground as you'd like to be for room to work. Next time I'll be picking one that avoids these frustrations. 😃 Hope that helps!

    You know it's going to get serious when wife needs to get involved ! Absolutely love those videos and the chanel - awesome work !! I'll do mine with the power hoist keeping the engine above the frame and slowly putting it into the frame so very similar to you. I also heard that putting actual frame into the sitting engine is even easier but that's just an overkill i think. Getting engine out and in is the most difficult job to do on those bikes !
