You forgot to show and mention how much important his the position of the pin for the right lubrication of the rod. Apart of this the video is not bad . Keep posting more videos and attention in the details, special in the important ones. Thanks.
Can't do that with the Honda CR 125/250 can cranks as it will ruin the can's rendering the wheels useless for rebuild. We use a fixture to hold the crank and cut the rod and pin in half with an cutoff saw and push the the stubs out of the wheels individually Iv'e done hundreds of them in the 43 years I worked for Falicon Crankshaft
@@doghousegp So you have rebuilt 50 cranks improperly! I hope you do know that every time you press out pin you weaken crank webs, and if big end pin is shot then you ruin crank once and for all
You showed of your tools nicely, but the example you put out is horrible. 1e mistake; when taking the cankschaft apart, you push a worn bigend pin through a honed hole and with that you damage the surface. The 2e mistake is; Your runout gauge, it only measures crankshaft thickness. Not the runout.

If you twist off plastic ties with a pair of pliers you eliminate the sharp edges. It becomes rather important after you catch one on your wrist and are stuck trying to convince emergency personal that you weren't trying to do yourself in... again.
@@doghousegp I saw you checking the cutting edge and asked my first year apprentice electrician son to tell me what you were thinking. He figured it out. UA-cam can be interesting in the number of ways a comment can be interpreted. Some channels are like a war zone so it's prudent to use words like prudent only misspelled as prunedent then wait and see if that gets things moving along. Just winging it here in isolation.

It's from a jig used to make photo radar camera mounts. Must be a joke in there somewhere, a flasher maybe. Well done on your plastic ties. Peace.
All you're proving running the dial indicators on top of the main shafts as they in turn roll on rollers is that they are round the only accurate way of establishing whether the crank has acceptable run out is to put it between centers and check it at the main surfaces. (and yeah I'm well aware of the fact that the Honda "can" cranks have the inside centers covered by the sheet metal "can" so you can't establish that the centers are true to each other) Iv'e built literally hundreds of these CR 125/250 cranks (the RS is just the roadrace version of a CR125) in my 43 years at Falicon Performance /Falicon Crankshaft By the way your build fixture is Sweeet
i love how this bike wil vibrate :)

Thanks.
I believe this is a 2 stroke crank...so that's not applicable here.
This is not a how to video
Esse virabrequim é para motor dois tempos, não existe essa entrada de lubrificação do pino.
The oil in the fuel provides the lubricant
How about a 1994 RS125RF/NF4?
very good
Nice
Sir, how much tons that jack bottle?
Good luck
I'd like to get those tools.. How can I get them? And how much do they cost?
Any house brew yet
hi!
Which oil did you use ?
yeah need this improvise tools
Hi, Nice video!!
could you please help me understand, when changing connecting rod kit, should we go for over size pin or same size pin? Thanks
Booo!!ma era meglio colonnine registrabili
How to ruin a crank. Never push a pin all the way through the web. And too separate the crank you should have a plate to go in between the webs..
Can't do that with the Honda CR 125/250 can cranks as it will ruin the can's rendering the wheels useless for rebuild.

I have done about 50 of the RS125 cranks this way and there are literally thousands of miles on them. I'm not worried about it at all.
@@JanCramer1 HOW DO YOU FIX THE RADIAL RUNOUT? HOW TO PUT THE WEB TO ZERO?
@@doghousegp So you have rebuilt 50 cranks improperly! I hope you do know that every time you press out pin you weaken crank webs, and if big end pin is shot then you ruin crank once and for all
Bhai kaha se ho
I'm just realizing that this crank is also in th cr125 ..
The '95 and up RS125 crank is different. The pre-'95 may be the same.
How much would you do mine for?🤷♂️

Could I send my crank to you and pay you to do it? Got a Honda foreman 450.

Sir used ppe for safety
Nice jig but that press, jikes.
I have upgraded since then......
Tkrj parts 👍
How you fix the radial runout??
Give one side a wack with a copper hammer
The fixture is built precisely enough that it need not be adjusted.

Watching Alan Mileard on utube would be better guide to this project he is a real pro
You ruined that crank the pins are tapered here's a tip cut the pins in half first...
Instead of cutting you can extract the pin from outside by using a bearing extractor to support the middle of the crank or a big plate

One of my biggest pet-peeves! The cutters I use are flush cut cutters and the only thing I use them on are zip-ties.

I have enough watching how you press pin trought both webs. It's not repair but destroy video.

I understand. That fixture is the key to doing this job.
