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 .
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.
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.
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.
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
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 ,,,
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.
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.

HOW MUCH GAP SHOULD BE THERE BETWEEN ROD AND FACE OF CRANK SIDE?
This is a accurate method of checking crankshaft run-out and misalignment.
thats how it must be done.. all crankshaft companies do this
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
@@grantfuller2016 if there is run out it will show on either side. There would be no use to use both, beside giving yourself a headache.

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..
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.
That’s one sexy balancing machine .
Very informative video! Take care!
Never needed to use a cut off wheel to remove a conrod before .. would love to see a factory team like HRC do that .. it would be fuggen hilarious
This is one of the options. Thank you for your interest.
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.
Yes , this also one of the problems.

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

How do you ensure the two crank halves are correctly aligned before pressing them together?
at the beginning with an angle and then I measure it

Very important vedio but how I can buy this centering crankshaft machine
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😉
Never been able to tap that lightly🤣
You have to get a special hammer ;)
I want buy link.
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.
Why u cut connect ing rod, with grinder, this not gi
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.

the disassembly of the connecting rod could have been done also in the hydraulic press, this would avoid cutting the connecting rod
I wanted to show another way to disassemble the crankshaft. I usually disassemble it under the press. See my other videos.
