Perfect video! Now all I need is a 12 inch grinder, 120ton press, a alignment tool that costs more then my car. Then I can change me bikes rod lol

[@jacobwestcott4536]

And perhaps a guy telling us how to do so. The fuck?

[@agie170hss2]

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. :-)

[@PaulXchannel]

Thank you for your opinion. You can see my another videos.

[@jeroendesterke9739]

Thank you - I was about to ask the same.

[@hlrembe62]

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.

[@briliankamil4594]

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.

[@PaulXchannel]

Thanks. I use various methods for repair. It's known in other videos.

[@sm400]

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..

[@keithwhitlock726]

Great video. I was taught to use a lead hamme. Be sure to wash hands after using.

[@mechanic3d]

This is a accurate method of checking crankshaft run-out and misalignment.

[@blackdaan]

thats how it must be done.. all crankshaft companies do this

[@grantfuller2016]

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

[@ErnestDuarte]

@@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.

[@grantfuller2016]

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 .

[@abandoneduniverses]

finally even with micrometers and correct 00.1mm +__ seems that the copper hammer on truing cant be avoided!! thanks for nice video!

[@PaulXchannel]

I am sorry. I am busy.

[@rivannirwana4355]

@@PaulXchannel oke thanks

[@wdobni]

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

[@briliankamil4594]

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.

[@starautoindustries1641]

HOW MUCH GAP SHOULD BE THERE BETWEEN ROD AND FACE OF CRANK SIDE?

[@mechanic3d]

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

[@PaulXchannel]

[@davek5151]

What is the minimum ton press I would need to remove and install ? Your video has inspired me to give it a try!

[@PaulXchannel]

My press - 50 ton

[@hlrembe62]

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.

[@hlrembe62]

Just to let you know I stole your fixture for checking alignment😉

[@trevorsmyth6746]

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 ,,,

[@komalpatel2825]

[@austinjunkman2449]

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.

[@Wolfdog370]

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

[@PaulXchannel]

This is one of the options. Thank you for your interest.

[@Swarfman64]

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.

[@PaulXchannel]

Yes , this also one of the problems.

[@Peter-V_00]

[@narsimhachary6227]

Sir why using cutoff machine instead of hydraulic press opening connecting rod

[@PaulXchannel]

Hi, because it is better for crank.No bad pressure for crank when disconnecting.

[@thorlopez8888]

@@PaulXchannel yes indeed

[@bigalsbash]

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.

[@PaulXchannel]

The 450cc rod is changed at 100 hrs preventive, later would a problem.

[@blackdaan]

why? its not like your going to use the old parts..

[@robipahovec4074]
