Hey Paul. Love the Crankshaft Truing stand. Always makes life easier when you have the right equipment for the job. Thanks for posting the video. All the best. Peter.
Don't be misled by this video. While the process shown is perfectly adequate, there was a lot of truing done off camera, I'm certain. There is no way a crank ever assembles this accurately in the press before dropping in the truing stand. Even using a die-set to position the halves very accurately, this still doesn't happen. Typically when just using a press such as in this video, the 2nd crank half is pressed onto the crankpin just a very small distance, and then the crank is trued fairly closely. Then press it further, and check/true again. This process is repeated a few times during assembly, because it's MUCH easier to true ("clock") the crank halves before the crank is fully assembled. The video is nicely done, and a clever use of other parts to build the indicating stand, however the video simply does not show the entire process. Be advised. :-)
I have several custom fixtures I have built over the years, especially for multicylinder Jet Skis and snowmobile engines,, that allow me to get extremely close to "dead on" straight cranks right out of the press. Back in the days of two stoke watercraft I averaged at least 1 crank rebuild a day thus the need for the fixtures: efficiency and speed.
For a single cylinder crankshaft like these, its nothing complicated really, we usually press it right away, then hit it, it will come out good, if the part is good. If it doesnt, then there are something wrong with the part, either the shaft is deformed or the crankpin hole isnt in correct distance or angle, which mean any further adjustment is impossible.
blackdaan He has left out a few “ tricks of the trade “ . Notice he seems only to true up one side , but the jig is designed to do both . You can do it with just one gauge but you have to keep swapping sides and sometimes it impossible to get both sides perfect at the same time
E. Duarte not true , you can have different amounts of run out on each side , right up to the point that you can have zero on one side and some on the other .
If you can budget the extra cost I prefer and use an air over hydraulic. They are more controllable when it gets down to the final millimeters of moving parts.
one thing still seems very mysterious.....how do you decide exactly where to strike with the copper hammer? does the dial indicator point at the correct spot? do you always strike the crankshaft flange? i suppose you learn by trial and error
Its simple really, there is only one hinge between 2 flange, when we hit it we only position the hinge either on the top or the bottom, and then hit the middle. If the dial get worse, rotate 180 and hit the middle again.
Can I ask how you know what point of the crank to hit when reading the gauges? As I can get mine good but I get lost on knowing what points to hit when reading the guages. Its The only think holding me back.. thanks
@@PaulXchannel so for instance.. if your on the flywheel side and the guage is at its highest point (with the rod furthest away) would you hit the primary side or the flywheel side? Thanks for your reply
Hello Paul. What kind of press is that and how many ton is it? I watched your other video with the harley crank and my 20 ton press wouldn't touch it, what ever you are using made it look easy.. Thanks.
I doing this more than 15 years. Some important moments are not record.... And at the end you check the shaft only on the clutch side??!. It is always necessary on the both sides (clutch and magneto) at the same time!
Use a 10mm sheet of glass with 80 grade wet and dry sandpaper and smooth off the crank webs if the scoring marks are more than 0.5 mm deep ,, don’t bother just buy a new crank ,, but if the are less than 0.5 reface then so you can get the correct conrod side clearance of 0.15 to 0.5 depending on the model ,,, make sure your conrod side clearance is within spec this is 100 times mor important than the outside width of the crank webs ,,,
04:00 not parallel by a long shot, or it's just the filming? no need to reposition,or hit it with the copper hammer to bring it to parallelism before assembling,you feel? also,no need to use the indicator on the left? thanks,nice video.
Ahm is plenty of room on left side. Key way not taking up all of crank area. Full hack even using a grinder. Tipping its a backyard crank job lol. Why post this shit teaching younger kids to grind away... you have a press and you use a grinder. Fukwit
hrmmm.. i believe i can make one of those truing stands. gonna give a shot. im thinking a nice sheet of 1/4 steel. maybe 1.5 foot by 1.5. 2 dial stands. some steel and some bearings. along with a caliper and i think could make one for about 150 bucks to 250.
Actually its the best option, If your bearing failed then you are pressing the damaged part of the pin through the crank, this way you press the cut pins toward the center saving the crank bores from galling.
Hi , because it is better for crank. No bad pressure for crank when disconnecting. Sometimes can a thin motocross crank burst. Then is better crank cut.
Thank you for posting this. I've never attempted to repair one myself but watching this gives me confidence. Is there any advice you could offer to someone like me? Sub'd and liked👍
It goes a lot easier if you just start the other side on 1/3 of the way then check and adjust. Then press it down 2/3 of the way, check and adjust, then all the way and check. The way your doing it by pressing it on the whole way then truing makes it much harder to get it to move where you want it.
Hi, because it is better for crank.No bad pressure for crank when disconnecting.Sometimes can a thin motocross crank burst. Then is better crakn cut. It is preventiv against demaging of crank.
Its easier to press half of a pin out than trying to press a full pin out common sense it not gunner hurt nothing is it if the rod is nackerd in the first place dont get why this lad has got so many thumbs down when all he has done is used is head and done it the easier way instead of coursing damage by pushing a full pin out
Hi , because it is better for crank. No bad pressure for crank when disconnecting. Sometimes can a thin motocross crank burst. Then is better crank cut. See my another video with standard disconnecting.

Good video best of luck 🤞
Very informative video! Take care!
finally even with micrometers and correct 00.1mm +__ seems that the copper hammer on truing cant be avoided!! thanks for nice video!
Thanks
Those are $20 micrometers....
I'm glad I'm not the only one that cuts with a grinder...it may seem savage method but absolutely do not force a damaged pin through crank web..
This is a accurate method of checking crankshaft run-out and misalignment.
thats how it must be done.. all crankshaft companies do this

Congratulations on the work. Where can I buy a desk like this? With the double dial indicators? What is the name of this tool? Thank you and success?

@@PaulXchannel oke thanks
What is the minimum ton press I would need to remove and install ? Your video has inspired me to give it a try!
My press - 50 ton
If you can budget the extra cost I prefer and use an air over hydraulic. They are more controllable when it gets down to the final millimeters of moving parts.
Just to let you know I stole your fixture for checking alignment😉
I’ll buy a new one instead thanks for the video thou

This is a proper way to change crankpin journal and connecting rod. hydraulic press forces the journal to press fit in crankshaft counter weights.

Very important vedio but how I can buy this centering crankshaft machine
Grate job🤝💯
how many micrometers the shaft must be larger than the hole?
0.08mm
@@PaulXchannel can the hole be widened by 2mm to insert a stronger rod?
Yes. It is possible.
A larger hole needs to be cut.

Hi paul x what will happen to the crank if not centered. Does it cause noisy engine?
Engine can vibration.
Not sure why the crank just wasn't pressed apart? 🤔

Hello sir
Yamahaszr Crankshaft timing gear Price.
high precision, I would like to understand the chainsaw stroke through the connecting rod is it to release the crankpin more easily? (traduc sorry)
Thank you .
The equipment is angle grinder 230mm.
Doing the cut makes it easier to press apart the pieces without damaging the parts.

Sir why using cutoff machine instead of hydraulic press opening connecting rod
Hi, because it is better for crank.No bad pressure for crank when disconnecting.
@@PaulXchannel yes indeed
The rod is changed usually because the bearing has failed. This damages the pin which would damage the crank half bore if it was pushed through.
The 450cc rod is changed at 100 hrs preventive, later would a problem.
why? its not like your going to use the old parts..
Very good job👍
