Just wanted to share a tool i made for easing getting the engine out of the frame.

No more sore back from lifting the engine out of the frame

well it sure is helpful having a hoist in the shop

good move. i still prefer the tilt'n'dump

Nicely done. Looks like one of those sorts of things that are a pain to design but easy to build.

What sort of car is that behind the bike?

Last time I "extracted" the engine, I used an engine hoist and rope similar to what you did. However, I used a method which combined the pseudo-laydown method and the hoist. It was better than the original "just pick it up" Iron Man method of previous years - but your method looks professional.

I did not think of the bracket you used to keep the lift vertical. What did you use for this bracket? It looks a little like copper water pipe.

Anyway, congrats on the back saver device.

The car in the back is a 1931 pontiac big six, as for the tool.

The bracket is made from a flat iron bar, that has been reinforced in the bend by another piece thats welded on. I guess i could have used a steel pipe instead. then i probably wouldnt have needed the reinforcement. I'll get better pictures of it tomorrow, and some measurements if anyone wants.

I would appreciate the extra pics and dimensions.
I currently have a K3 engine on my rebuild stand and a K6 scheduled for the end of this riding season.

Thanks

Bloody Brilliant Man!!!

Add that to my list of needed things before my winter rebuild. Last few times were, lay engine sideways, frame over that debacles...

Nice work!
My problem, the engine wants to tilt forward. Did you have this problem?

frodef2 · « **Reply #9 on:** August 16, 2008, 04:36:38 pm »

i'm sorry for being slow on the drawings and measurements. but im having some trouble with the engine.
while dismantling the cam holders, the treads came out with one of the bolts. PO must have tightened them down too much.

Also, I never thought it would be THIS hard to get a helicoil kit in a reasonably developed country as Norway. the city closest to me has almost 100k inhabitants. But not a single hardware store had any in stock. the closest i got to a kit was a special order for a full kit, which would have set me back 650$.

anyway, here are some more pictures and some quick measurements. I didnt have a angle measurement tool at hand for the bends. When i made it i just bent them at apropriate places.
Measurement C = 11cm / 4,33 inches, and the upper eye nut is 8cm/3,14inches from the end of the bend
Measurement B = 14cm / 5,51 inches
measurement A = 11cm / 4,33 inches, and the lower eye nut is placed at 9,5cm/3,7 inches from the end of the bend.

in this picture the engine is actually hanging about 25cm (10 inches for you americans) above the floor, and the engine is quite stable

the design of this "jig" isnt that important. you just have to find something that you can bend into a C shape. that will hold about 100kg. just make sure it will get around the frame over the engine.

That is really sweet. I did mine alone and used 3 "musical straps".... move a little, re-strap, move a little more, re-strap, etc. What you got there is so much better than what I did.

boatsdickson · « **Reply #11 on:** August 16, 2008, 06:51:07 pm »

Cool, thanx, it sure will a handy device sometime..... The opposite here for helicoils. I can findem easy, just affording them....damn.

frodef2 · « **Reply #12 on:** August 16, 2008, 07:01:36 pm »

I managed to find a cheap kit online. a 6mm kit set me back about 40$. they are not helicoil brand though. they are called v-coil. http://www.voelkel.com/english/index.html. The bad thing is they have havent showed up yet. not sure if its the company i ordered from thats slow or the postal service. thats why i like to go to the store to get something. when its in your hand, its yours.

Frode

Thanks for the info on the Frode "CB Engine Extractor" model
CB-EE1.

Examination of the photos indicate that the angle a-b is about 70 degrees and the angle b-c is about 125 degrees and total bar length would be about 48cm/18,89 inches.

You said that
'the design of this "jig" isn't that important. you just have to find something that you can bend into a C shape. that will hold about 100kg/220lbs. just make sure it will get around the frame over the engine.'

You found the 'shape'.

I am sure that the angles - while not super critical (+/- 5 degrees) - are important in clearing the frame.

Checked out the voelkel site - their web site does not provide great depth about their products. Hope that you receive them shortly.

Good Luck
Tom

Excellent work! I was just getting ready to remove the engine from my latest chopper but I'll be making one of these first! Although a chain hoist is nice, I'll be using a cherry picker to do the lifting and see how it goes. Thanks very much!

Regarding your stripped bolt holes, here's what I did......

I was going to post a video of the jig in action today, as i am done with the engine rebuild.
But i had to rely on my dad as a camera man. He actually forgot to press record on the camera. and now the engine is in the frame all fastened and with the carbs on. But no video. the only good thing is that the process was so easy im almost tempted to get the engine out of the frame again just to record it.

Very nice work.
I'll be thinking about making one of these also!
Thank you!

I have seen some cool tools in my time but this takes the cake. I will have to build one for sure. You did a great job describing how you constructed this. Thanks for your help.

Thats briliant wish i had seen this post before , just got inside from lifting my motor out like i was the Hulk. man they are heavy by yourself, but i know how its going back in now with one of these lifters.

Terry in Australia · « **Reply #21 on:** February 01, 2009, 12:48:07 am »

That's a great tool mate, well done! In hindsight, Honda should have included one with every "fragile" F2/F3, there aren't too many that haven't had the engine out at least once by now, ha ha! Cheers, Terry.

Yet another awesome tool you'll never find in a book!!! I was going back and forth on whether or not to pull the engine from my build, but this just decided it for me!! One question, the hook you have on the one side of the engine that has the circle with plastic or something in it. How did you make that?

Thanks!!

frodef2 · « **Reply #23 on:** April 08, 2009, 02:34:33 pm »

the white ring is made of nylon. and its inserted in a ring i made in my dads lathe. I havent used that part lately. i could never get the nylon ring to stick inside the metal ring. Instead i got a nylon rope thats round and a bit longer. the flat nylon load band i used at first was too wide to seat firmly around the oil plug. thats why i made the ring.

manjisann · « **Reply #24 on:** April 08, 2009, 03:37:52 pm »

Hmmm sadly I don't have access to a lathe. I may just have to adapt the idea. Either way, the Hook and hoist thing is brilliant! Thanks for sharing it!
