ready to split my cases

[trx]

im about ready to split the cases on my 1986 trx250r bottom i have the splitter and puller and the flywheel puller as will


i know how everything come out and go's in


i this need to know what side to split first and what side to put back in first
EXAMPLE i put the splitter on the right case then push out the crank or do i put the splillter on the left case and so everything comes out on the right with the tranny and crank or oppisite way

and when i putting them back toeghter should i put the tranny and crank on the left cases then close them or put everything in the right cases then put the left case on

so how do honda guys do ur spliiting of the cases i have all the tools and experence to do it i this need to know this.thanks

Stator side down. I wouldnt use the splitter unless its needed. Just hit it around the seem with a rubber mallet. It should come apart. If you have to use the splitter, make sure everything is nice and even before you start cranking. Thats why I like the tusk splitter. It has all its fingers on the same plane. You can just mount the fingers flush on the cases.

I always put the clutch side down and the stator side up, make sure you get all the bolts out (if you get them all out it should come apart easily) and try to pull the left case off the crank. When putting it back together everything goes in the right case, when putting the main bearings in, put your cases in the sun and put the bearings in the freezer, (they almost drop in that way) wait til everything cools or warms to room temp. Then put the crank in the freezer and the cases in the sun (including bearings), when putting crank the crank seals in, dont put them in too far ( you will block of the oil flow to the main bearings), so i suggest putting the seals in before putting the top end on. then blowing air down the oil holes and making sure you did not block them off, you dont need to put them on that far, just enought so that they seal against the crank and the cases.

alright cool thanks guys

im going to split them today

is it necassery to use a flywheel puller?

[socket17]

case splitter.. flat head screwdriver??? lol. i did a 86 a few weeks ago.. i found it easy.. wish it was set up more like the banshee you take the top off not the side.. but cant have everything..

1 more note.. Make sure you lable all your stuff.. also when putting it back together i had a issuse with one of the shifter pines.. they need to line up prefectly with the left side when sliding together.

Yeah I dont know what I was thinkin lol. Stator side up. Thats what I ment lol. There is only one way is what I was getting at.


Yes, on the flywheel puller

will i started wrenching on it about 1 hour ago and this got the whole right side done i labled and put everything in a certain order aswill
the only thing left is to get the flywheel off but i have to order a flywheel puller from rockymountain tommorow

so besides that im done i this have to take the cases apart drop the new bearings and seals in and gaskets and the new used crank i bought slap it toeghter and my bottom end is done


my other question is what shound i use to clean all the gears and cases before assembly so i know everything is clean

I just spray them down with some carb cleaner and then give them a light coat of ATF. Here is a link you can read about doing the job at hand. Honda CRM250R Mark 2 Engine Rebuild Project - A detailed guide to rebuilding an off-road two-stroke single
