Royal Enfield Bullet splitting flywheels, replacing big end and reassembling and truing crank. 

That was fascinating! I've never seen this done before and would have had no idea how to start with doing it myself. You've done a terrific job! The next one will be to get that press indoors, if only to stop you from catching your death.

Thanks for this Paul. Very interesting !! 👌

Excellent video Paul, thanks for taking the time to film it, and it ain't half rained past two days.

In many ways it is much easier than a modern crank to handle, many thanks for sharing.

Thanks for these videos, great to watch someone who knows what they are doing!

Great video Paul , I have just came across this one now , I never realised that there was such an art in setting up a crankshaft

Nice work Paul. Thanks for showing us the whole process. On a roofing job in Wales some years ago I learnt that waiting 'til the rain stops is not any option.

That reminds me of watching Jack Gray (of Gander & Gray) doing the same thing, bumping flywheels on the end of a portion of tree trunk on the floor. Looked crude but (with patience) great precision. Nice to see the old skills are still around.

I was taught using a copper hammer, I find it much easier than swinging the crank about.

Great content Paul , thank you

Very good film, nice to see all the step and what can be achieved with a block of wood, inertia and a huge amount of skill.

Excellent! I look forward to each video. Words cannot describe how grateful i am.

nice work paul.

I watched Mick Waller doing this to a C15 crank last night. It’s great watching masters at work - even if it does leave me envious of your skills!

First time I’ve seen this 😮 awesome! Always wanted to see this process and how you did it. Phenomenal 👍👌👏

While I quite enjoy the runs around the Welsh countryside, the in shop presentations are very informative. I’d never seen a press-together crank brought in before. The wood block taps were new for me. It’s not likely I’d have tried lining one of these up before seeing this. Having seen it done I might give it a shot by now. Thanks.

Thanks Paul for this video. Lots of really useful tips here. I’m sorting out a Velocette MSS and I’m thinking I’ll follow your lead👍👍

great result and most enjoyable to watch, thanks again

I was lucky enough to buy a Humphries & Simon crankshaft jig complete with tooling. Never done a crank job before but have a Norton single to fit an Alpha big bearing and crankpin to which means new outer race to press into conrod and may need honing? I have a 10 ton hydraulic bench press which I hope will part the flywheels. I am using a steel tube with a 10mm thick wall that the flywheels will pas through and a slot milled out of it from end to end for the conrod to pass through and a 10mm thick steel plate with a slot milled out of it for the big end and rod to pass through. Plate fits between flywheels, the jig is a cast iron machined bed with 2 round upright posts at a perfect right angle, T nuts to clamp flywheel to base and a clamp assembly that pulls both flywheels against to 2 upright posts and told to tighten up crank pin nut and then clock the crank...... Fingers crossed.

Thank you Paul. A really practical approach.

Found it! This is excellent!! Thanks Paul!!

Always enjoy your videos.

First time I’ve seen that been done well impressed 👀

Great video Paul , thank you

Thanks paul .another great video .

Enjoyed your video Paul. Happy New Year!

good job

It is worth mentioning that, of course, the lathe centres must not be flexing the flywheels together by pushing too hard. Also, I would continue, no need to bump the flywheels any more but now they need wedging opposite the crankpin to finely bring them into perfect alignment. The wedging can be done with a bolt that just fits between the two halves and the nut unwound to provide inside pressure. Conversely the flywheels could be squeezed in the vice. It is not entirely true that it is ok to have the runout rising and falling together as it indicates that the shafts are not running parallel which is no good for the main bearings.

Good and nice

Really interesting video👍

Very interesting video sir

Paul ge zijt een ware Meester , een kunstenaar . Ik denk dat de tovernar Merlin een goede leerling aan u zou gehad hebben ,dank u voor dit leerrijke stukje motor techniek .

Great video Paul, it's good to see people will invest in their bikes and repair rather than forget about them or just replace with another. Just out of interest I did the same thing on my year 2000 500 bullet 3 years ago, I have the luxery of access to a hydraulic press and noticed that minimal pressure measured in tons was required on the bullet crank pin to push out whereas both an MZ ETZ250 and TS125 crank assembly were in the region of 21 ton to free and a steady continues 18 tons to press out, is this the norm for 2 V 4 stroke or was Mr Kaden a little more exact 🙄. Keep up the good work, cheers.

Great video Paul, I’ll ask you a question elsewhere....

Nice video Paul but couldn't see how you aligned the two flywheel halves accurately before the final press. Get it even a fraction out and your dial gauge readings will be all over the place. Is there a procedure to line the two halves up other than a good straight edge?

Great video Paul. If you get a chance next time can you film liner honing of Hitchcock's RE13 on conn rod and getting the right clearance between liner and needle bearing, Cheers !

Hi Paul Love your videos. Been fitting a big end assembly to a VB 600, following your advice on the R.Enfield crank. All goes well untill I tighten up the nuts (tapered pin with peg to line up oil hole) the wheels go out of balance. Any advice would be gratefully received. Have tried socket wrench and windtly gun. Thanks. Vince (Anglesey)

Abcerluy brilliant

I see you like to work in the rain outside to stop anything overheating and it washes your crank at the same time!

Paul..very interesting and informative film . I've only just come across your films and I really have enjoyed watching the content and learning from your narration. Can I just ask a quick Q and call me thick but...Why didn't they make the crank pins with splines or a flat to eliminate all this time consuming 'Truing' and also..What stops the 2 halves from creeping out of true if there is no positive location , as the primary side has a different load than the timing side ???? Kind regards

Very much enjoying your video’s is there a risk of disturbing the flywheels when you tighten the crank pin nuts ?

Great, thank’s for an in depth video on the subject. Can I do my bsa m20 the same way ?

Very nice, Thank you. Is there a figure to tighten the crankpin nuts to, or is it down to experience please?

What is the outside diameter of the crank flywheels, I'd like to know if I can do this using my 11" lathe. Thanks in advance. They look to be between 6-8" but I can't seem to find the dimension online.

Hi Paul, I have 2011 Classic 500 Electra EFI. I see the exhaust pipe discoloration at 2 places, where the O2 sensor is (bend pipe) and at the middle of the exhaust pipe, is that normal? Do you know of any fix to the problem?

The Con-Rods do NOT have pressed in bushings which, after wear, can then be pressed-out & replaced with new ones ? Or it is just a matter of ease to secure & install a completely new combination ?

By heck, that block of wood was a feast for the eyes 😂. What causes a big end to get so sloppy in your experience? Neglected oil changes I'm guessing.

I need your opinion about my Royal enfield classic . I got some type of debris from engine.How can I contact you...

How heavey are thos cranks asemblys? Have u ever lost ur grip of 1 as u dress it off that block

How much mm of Crank Dia and width dimensions

This is light weight crank change into heavy

Great stuff. Thanks. What's your average number of bumps to get truth?

hello i just have a quarry i.e., my bullet electra 2005 5S Cast Iron connecting rod is play only side ways ....... so is it safe to install new block piston ....???

What are those meters for crankwheels on bothsides?

What's the weight of the crank?

How much miles can a 500 bullet big end have before getting too much play? (Is it a weak sport or?)

Sorry to take you OT.. besides my diesel bullet(winsun 188) i have since a few month's a 500 '94 bullet which i would like to stay petrol.. (as it ran very good with a PWK carb..) Looking at all the nuts and bolts, and still having the india-dunlop tyres- as new- on it, it seems like it has run very low mileage.. Yet the cylinder is worn out.. seriously.. By your experience.. are soft/badly hardened cylinders an issue with 90's bullets?
