How To Install a Dirt Bike Crankshaft using the Tusk Crank Puller/Installer

[@HorsepowerHouse]

Not sure why people 'disapprove' this. It works great. Just did my YZ250. Was not very difficult.

[@Motoguy2234]

Becusee it doesn’t come with the right size bolts. At least not for my yz 125

[@stevo_350]

This video helped me so much. And relieved a lot of stress, bought the tool and it made my life so much easier. Thank you.

[@justinfeagans6171]

Awesome demo! I love the tech tips you guys give, really makes working on your bike a breeze.

[@richdelgzz]

Great Video! I'm dissembling my 08 CRF250R now for a complete engine rebuild. Couldn't do it without RM!

[@GregoryReimann]

Tool was totally worth it! Great instruction video helped with the project as well.

[@rmatvmc]

Glad it helped! Thanks for checking out the video.

[@troybrown6218]

Great tool. I watched this video,then did my crank in 5 minutes.

[@Drain09]

Used the tool, but the included bolts don’t have a big enough area for the collar to evenly hold onto. Feel like they needed washers to keep the pressure even against the bolt head and not round them off?

[@stevebillow395]

Thanks for the info. Looks like I'm getting that sucker

[@alexguiver815]

Building up to using this tool for the first time and even with the collar removed, it's 1mm too big in diameter to fit through the crank seal aperture on my Yamaha DT125R cases which means it can't push on the inner race of the main bearing to avoid transmitting a side load through the ballrace. Possibly I could smash up one of the old main bearings to get the inner race out, put that on top of the new main bearing so it's proud of the case, then use the puller on that so the force is only being transmitted through the inner race of the new main bearing. Ball bearing races don't like side loadings. Hope someone at RM can help

[@troybrown6218]

Did you try the rods?

[@alexguiver815]

@@troybrown6218 The load path through the bearing will be the same even if you use the rods as shown. Eventually I had an adapter made to press on the inner race as you do up the nut. Local machine shop did it for cheap once I did some measuring and supplied a drawing

[@kczbluesman]

That was my first thought when he was setting up the tool.

[@kevingrespan2191]

I think I have the same problem. Trying to set both cases in together. Crank is already pulled in one case. Trying to pull the crank thru the other side of the crank( the one with ridges at the end of the crank shaft). The hex bushing keeps coming right off since there’s nothing keeping it tension. On the other side it had the female adapter to make it easy

[@ronanrogers4127]

Should we lightly oil the crankshaft or bearing inner race?

[@TheEvilive]

I am having a problem with my LT250r bottom end. When i install the second case the crank falls out of the first case. I think its the original crank. and the cases then don't fit together tightly. i was thinking the Bearing surface is a little worn out. thoughts?

did u ever figure out the issue? dealing with this bullshit rn

[@jessethebaldyventura2391]

What about head-spacing the crank?

[@phillipsnow5053]

Very easy to follow video. Thanks!!

[@aaronputnam7513]

I bought the tool and the c clip kit for my son’s KX 65. The c clip is too large for the 65 crank. Is there a kit with smaller ones in it??

Very informative video. Unfortunately, I bought this for my 66cc 2 stroke and all of the adapters are too large for my crank shaft. Tusk couldn't have included some some smaller adapters???

[@rafaelperez6070]

I am doing one right now and what I did was I used the nut that goes on that side, it did not fit in the case you put first , and bought another one and grind out parts of nut to make it fit in. Good luck

[@rafaelperez6070]

That's what's up !!! I new you were probably working on it still just like me I have opened and closed that 65 motor about 6 times in 2 days , when I closed the case the rod didn't move smoothly and I saw a bearing out of place not all the way in put it where it should have been and the main (bearing came out with the rod ) now I need to buy a bearing splitter because is not even 1/6" opening in the back so there is no other solution I tried to fabricate a "home made tool" I tough it would work bit i ended up damaging the bearing a bit now its back to square one and a 2 week wait to get the bearings and tools to finish this , I. Not a mechanic a know some 2 stroke engines , not looking forward to 4 strokes ,too much money ... I had enough with 50 ,65 ktms and 85 kx , 9m glad I could give you a tip that worked ,if you have a tip for my problem ,your more that welcome 🙏 to help... be safe out there riding we can't afford to go to the hospitals , my little one broke his left arm yesterday they took the cast out and I'm getting his bike ready to race for when his ready to ride again. Bike dialed backyard track prime...

[@rafaelperez6070]

@ yes you'll end up whit 3 motor cases whiteout including your clutch cover and stator cover, and that's exactly the tools I bought, now I need a bearing separator because I took it out because one bearing was a bit of and the bearing stuck to the crank and I can't, not supposed to pull the crank in the case whit the bearing on the crank it should be on the case sitting flush on the case, that's another tool I need hopefully you don't do the same mistake , install the bearings in the case first then pull the crank in from bought sides and your seals come in from the outside so you can keep them safe until your case is closed

[@rafaelperez6070]

I used the flat part of the crank puller but they are goin in very easily with a bit of heat in the case.

[@rafaelperez6070]

@ not recommending, but I use a benzomatic .

[@darrenwaugh5756]

Doing my first engine build 87 kx 250 flywheel side is 8mm bolt other side I need the c clip adaptor will it fit my bike

[@smirmeister]

Can you explain why you opted to use the bars instead resting the tool on the inner race? Just thinking about it, it seems like the bearing is being subjected to a lot of axial force that will most likely damage or at the very least reduce service life.

[@joshmx28]

I was thinking the same thing. Also the flex you are putting on the case half isn't ideal. I would say push right against that inner race unless it's just absolutely is not an option.

[@Mark-vx5dt]

@@joshmx28 +1 - definitely pull against the inner race. Then there is zero load on the bearings, no risk of damaging a brand new bearing before you even close up the case!

[@alexguiver815]

Yes I agree. Possibly you could smash up one of the old main bearings to get the inner race out, put that on top of the new main bearing so it's proud of the case, then use the puller on that so the force is only being transmitted through the inner race of the new main bearing.

I have this tool and im not sure how to do this on my KX 65

[@philgraves7814]

Will this work on 1990 ktm 250

[@Kdjoao]

Had to hammer it in on one of the side and now main bearing have a lot of play in it and the crank didn't even made it all the way in. You think this still good to use?

[@scott2495]

What a stupid question

[@kdir8727]

No flange sealant between the cases?. Probably for the video not. But great tool to have it.

[@henrikkvalheimeriksen5754]

At 6:58 he states that both halves have liquid gasket applied

Why the new build leaking oil ?

[@pkduran4418]

[@kellybrown6988]

I tried using this tool and it just spins the crank and doesn’t pull the cases together.

Will this tool work on scooter from the Philippines let me know thanks

[@masonroy2944]

Gotta be a lil more specific than “scooter from Philippines”

[@jakan756]

great tool! Did you use the 12 or 10 mm bolt in crankshaft when you pulled it thru.

[@darrylpatterson7365]

If you put the crank in the freezer for a few hours it will drop right in no tools needed.

[@jonno904]

What are the internal diameters of the main collet ?

[@moto_tech_braap_itout9852]

Do i need that c clip thing for a kx250f or only the kx250 2 stroke needs that ?

The C-clip Adaptor is only required for 2 stroke KX models.

[@smileyrod11]

CAN YOU USE THIS TOOL ON SCOOTER

[@emmanuelhud1]

Yes you can it's the exact same tool. Depending on where you get it, it may have different attachments. But they are all the same.... Tusk, motion pro and Buzzetti are all the same but prices do vary. motion pro and Tusk being the most expensive. Go with Buzzetti. In my opinion they are the best and not over priced. Also if you live in England or UK Buzzetti is kinda the only option as the other ones are made for the American Market.

[@donnismoo1498]

No stress on the rod but now youre bearings are forced into the casing!! no need tot freeze anything.. Lesson 1 from the mechanical engineer : Heat up youre casings, no tools, no stress.

[@scott2495]

How long would you heat the casings for? Would you use a heat gun or blow torch?

[@chrisdaniel132]

@@scott2495 heat gun 🔫 is a little slower but much preferred than a torch. A lot less chance of overheating.

Helped me a great deal this. Although in the uk I couldn’t find any tusk tools. So had to buy another brand that didn’t come with the bars.

[@bikemancody2752]

You can buy the 3/8 key stock locally in the UK for sure.

[@scott2495]

What tool did you go for?

[@mareksumguy1887]

Crap tool. It should be using the inner race to push up against... so that there’s zero axial/thrust load on the bearings!

[@coloradodirtbike5930]

You know of a better tool?

[@alexguiver815]

Yes I agree. Possibly you could smash up one of the old main bearings to get the inner race out, put that on top of the new main bearing so it's proud of the case, then use the puller on that so the force is only being transmitted through the inner race of the new main bearing.

[@RideWithTheWolf]

Why can't you just use a large washer and a nut?

[@rmatvmc]

This tool ensures that you're applying even pressure to the crank (using the steel bars shown at 5:00) which is important for proper crank installation. Plus, this tool comes with multiple different adaptors so it can be used on a variety of engines.

[@122martin122]

The design isnt good, you are forcing on the ball bearing, expecialy the balls, wich leaves a mark on the race and damage your new bearing. You should pull on the crank while the tool is pulling on the inner race

[@alexguiver815]

Agreed! Possibly smash up one of the old main bearings to get the inner race out, put that on top of the new main bearing so it's proud of the case, then use the puller on that so the force is only being transmitted through the inner race of the new main bearing.
