I did this to my 2013 KLR 650. It had 59,000 km on it and the cam tensioner was as at it's limit. I had no desire to split the engine just to replace a cam chain. Used the chain break to push the pin out of the old chain, attached the new chain, and fed it through. Pushed the new pin back in place and used the chain break to mushroom the end of the pin (checked it with the digital caliper). Checked for kinks and put it back together. Working great (so far)!
This guy is slick . I watched this years ago before the farm got raided!! The good ole days of the lake partys anyways when i saw this and how he heated the house he inspired me to be frugal!
If you're going to do this surely 1) use a chain splitter so you actually have a link that will move when you put it back together rather than effectively having 2 links welded together having to negotiate the sprocket and 2)Why not take spark plug out to lower compression, connect new chain to link, then turn engine with socket feeding on new chain whilst pulling old chain out, then re-connect at top without having to remove top sprocket and leaving no chance of timing going out !
Should go into business together and come out with a timing chain with a master link pre installed ...or just sell that size chain master links ... Great video...Got a xr80 with bad chain and I'm assuming crank sprocket...it jumped time and quit running...put it back in time and it instantly jumped way out of time again without jumping teeth on the top cam sprocket...just tearing into it ...just thought I would check for a video and seen yours. Thanks for the video ..
superb idea .i did this and used a £1.99 pen engraver to cut the pin and put a split link in .a little care and save u basically the £70 an hour repair bill..ps u can buy both types of split link too .one with the slider pin which i used or the one u simply tap a small X in the centre of the link pin to mushroom the head over .piece of piss
That was a brilliant short cut. Who gives a rip on an old bike like this? Just cheat it in there if that's what you prefer and ride! I may use this, thanks man
gonna try this on my xj900s... similar to a seca 900..but newer version. I dont wanna take the whole engine apart. Question about your bike is, was or is there a cam chain tensioner on the bike? I'm going to take the head off my engine, after making sure its at TDC, grab the cam chain with a pair of locking pliers, then remove my cam chain tensioner. Use a dremel to take out the pin on the old cam chain, pull thru, and use a new pin on the new one. Thanks for the video bud.
Think I'd try breaking the chain with a proper chain breaker than hacking at it. The weld, no way. Breaker again for re-inserting pin. If that chain is a Hy-Vo, your splitting the engine regardless.
Well if he didn't disconnect the CDI box he may have partly fried it. I've just had to get another S/H one due to some similar previous welding muppetry. Maybe as the welding was so quick it didn't cause a problem, but it wasn't a problem he considered. It takes less than half an hour to properly expose the cam chain
If you do this to a chain without the proper link like he does, you have more chances to screw up the chain and have a god damn engine repair that will cost you a lot. Replacing the cam chain doing the proper job will cost you a maximum of one day even for a curious amateur that have basic knowledge in how an engine works. Just have the bike manual or follow a DIY thread on forums, both are useful. Respect the screw torques and set the correct timing, it will be difficult to go wrong. I'm not a mechanic and have this done in half a day, of course my bike don't need to remove the engine, some of them need.
sneaky says it all,,,,,why do a half way job when its not all that hard to do it the right way? Ive overhauled those things several times, starting at noon, and replacing piston, rings, and reline cylinder and cam chain and been riding by 6pm...If you know what you are doing, do it right.
That top sprocket was absolutely stuffed, entertaining but not practical. You could accesss the bottom sprocket in less time than you spent breaking, connecting and welding the chain.
i got a box stock gx200 honda and i put a arc flywheel and when i rid it now im getting real bad vibrations at hafe throtal and when im at top speed its smooth and idal it is shakey its on a mini bike y is that it wasent doing it with the stock fkywheel
Mercedes use a bracket over the cam sprocket on their engines that leaves just enough room to get at a link to remove it. The tool doesn't leave enough room for the chain to jump so you fit both ends of your new chain to the old with temporary clevis type links. You then just rotate the engine until the old chain is fed completely out, and reconnect with a new soft link. The benefit is that you don't even need to remove the tensioner completely, just slack it off enough to get the new link to connect.
Z0mbieslayer: my 2004 nissan xtrail has 200,000 miles on it and the timing chain has snapped and the new one is rattling again. Also have a 2003 toyota hilux and that needs a new alternator. It has 158,000 miles on it. Burn.
i thought of this but then i was like you cant diconnect a timing chain unless ur an idiot and wanna pay almost 2 grand to rebuild my 250 because of a dropped valve

I would've thought that to be a better practice than welding it.

I laughed when you said you would " rather be drinking beer and riding". There's your sign.
Funny, as soon as you said Sneaky way... I knew what you were going to do. Very good. :)

Without watching this before hand and never having done it before, I kind of knew what you were going to do to replace it! 😂
did this 2 years ago bike still running great. Don't let the shop boy tell ya it can't be done cause it can.
Good on you, an inventive way to solve your problem, hope it holds!
+Dave Watts IVE DRIVEN THE BIKE IN 2014 AND DOING FINE
Im with you buddy. I don't know why this isnt a standard practice
Nice work the easy way.
That's the way,you go Dave
ha ha ... cool! me and my mate will try that on his DT175 (1979)
Thanks for the video it will help me in the future
Fantastic job thanks

The flywheel puller is just a bolt you can buy at home depot for a couple bucks

GREAT vid! Any tips on replacing auto cam chain tensioner on my Yam XJ600? cheers.

Jap cars don't need parts. My 95 subaru has 250k miles and still runs great. My dads 92 toyota pick up has over 300k and still runs.
If its stupid but works, it aint stupid.
I would have replaced the stuck junk chain tensioner first. Probably didn’t even need a new chain.

Thing is that takes a special tool and intelligence
That is 1 nasty repair
Well has the chain broke yet?
i got a box stock gx200 honda and i put a arc flywheel and when i rid it now im getting real bad vibrations at hafe throtal and when im at top speed its smooth and idal it is shakey its on a mini bike y is that it wasent doing it with the stock fkywheel
Shit I bought that bike from him 3 days ago..... Hahaha
Legend.
About how many hours, or miles, does it take for the average 4-stroke thumper (single cylinder) to need a new cam chain?
I got a gy6 150cc with 12k
IVE BEEN THERE AND DRIVEN THAT BIKE.. YOU CAN HEAR THE TICK TICK TICK FROM THE WELD HE PUT ON THERE.. ONE LINK IS RIGID I THINK
The pin is an interference fit anyhow,it's locked into the outerlink and doesn't move as standard
Splitlink 👌
We just remove the Magneto case cover, 10 minutes and lean the bike on it's right side 30 minutes before removal.
Wouldnt wanna do it on ya Fireblade : )

nice part about hondas haha... 8 months stopped, really poorly mainteined and starts right up... nice trick tho
should work good

Thinking about trying this on my 99 v star 650. I've seen another redneck do it with a master link.... No welding involved
They sell Master links
Now go get a brew
genius =)
why didnt dave just replace the tensioner? 2 bolts and its done....
NOT TRUE, the tensioner comes up through the bottom of the cylinder
genius
hahahah iv done this !!!!
There 70 bucks now lol
If your chain is worn out its best to also replace cam sprocket and chain guids and tensioner. This way is just a lazy ass way to fix things.
3
That sprocket is TOTALLY fucked. Why not replace it?????
if it work it ain't stupid Hahaha
Dude you stole this video wtf? This isn't Dave.
Hahhahaha
i thought of this but then i was like you cant diconnect a timing chain unless ur an idiot and wanna pay almost 2 grand to rebuild my 250 because of a dropped valve
all you had to do was take the flywheel off 🤣
