$20 hot plate from Walmart. Heated case halves to around 280°. I had to cover the entire unit with a cardboard box (essentially making an oven) though to get the aluminum that hot. The heavier bearings fell out of the case, and the smaller bearings were easy to tap out. With the case halves that hot, the room temperature bearings fell into the bore, no tapping required. No freezing of the bearings, either. I don’t like doing that, because as they warm, they draw condensation and you risk the balls starting to rust.
I liked the use of a socket in the center of the old and new bearing to keep the outer races lined up. Good trick
KTM tells you in the factory service manual to put the case halves in the oven at a certain temp and amount of time then bang them on a piece of wood and the bearings should all fall out.
Hi from Guayaquil - Ecuador. I'm 30 and I work repairing motorcycles. Thanks for sharing.
Great editing, easy to comprehend.
High quality HEAT gun will work great on heating the Cases (use a electronic temp reader to watch the temp).
Love your vids guys
Great video bro
Rather than peening the case over the spun bearing and causing maybe aluminium to break off during engine operation you could of just used your center punch an 1/8 inch from the bearing into the case in maybe 3 locations and that would have displaced enough material to hold that bearing.
What size, and brand collet for the blind flange bearing?
What size bearing puller for the blind collet
Can anyone tell me what size that blind bearing puller is?.
When I put the race on the crank I had kept the crank wrapped in plastic in the freezer over night, then heated the race, pulled the crank out of the freezer, mounted the crank in the vice sideways so I could drop the race in place, and the race literally dropped right on
Right ! Dont hit the case braking it in half, then try to glue it together .
Ever heard of using dry ice?
I ordered the tool to pull the bearing from the case, it just happened to be to small for the bearing
What code number for the main crankshaft bearing for ktm exc300 2017? Are 62/32 c3 and 207rc3 ?
I’m working on my 2010 ktm 300xc what bearing removal tool do I need to order from Rocky Mountain atv to remove the crank bearings. Name & part# please
Remove bearings without heating is not good for case. Heat case to 200-250 celsius and bearing remove at 10 seconds with resin hummer
Can we use hydraulics to install bearings
Pro-video, but we need a connection Rod replacement tips.
I don't see a 45mm puller in the tusk kit?
Which tool are you referring to? The crank bearing and gear puller or the bearing remover?
The 45mm puller is sold seperatly www.rockymountainatvmc.com/parts/tusk-bearing-remover-collet-p
or depending on your bike you could use one of these www.rockymountainatvmc.com/parts/tusk-crank-bearing-puller-tool-p -Charles
