Splitting the case question

[corypro]

So I'm about to split my crankcase but I had a question. The manual that I'm following wants me to take out the clutch, kick start gear and the gear on the end of the crankshaft. Is this necessary? It looks like I can just split it and it should slide out.

Manual is there for a reason

You have to pull the clutch basket off to get at and un bolt the bearing retainer.

 

Pull the flywheel off to get at and unbolt the stator/plate.

 

Can leave the gear on the end of the crank shaft, unless your changing that side (right) crank seal (which you should change them all anyways seeing that your going to be in there).

 

Kicker shaft/gear can be left in but it slides in and outa the case in 1 second. Makes things easer with it out.

 

Idler gear can stay on also.

 

Use a rubber mallet to split it, don't use a metal hammer + hit where the clutch cover and flywheel cover bolts go so you don't crack the cases.

 

If you need a hand or get stuck just ask, i have a shit load of detailed picks ive taken of every nut and bolt for the engine being taken apart and then built inside and out, step by step.

 

Pressure test it when done, then rock out!

 

Very simple stuff.

 

What are you splitting for?

 

Have fun.

I'm splitting it to repair the connector rod bearing. The previous owner blew the engine and upon replacing the pistons, I noticed loads of freeplay which leads me to believe there is no bearing left.

 

The main reason why I didnt want to remove the gears isn't because I'm lazy. It's just because I'm afraid of screwing up the timing. The manual doesn't ever talk about it when dismantling these gears so I just wanted to play it safe

Dont worry,the only timing issue is on the flywheel side and its keyed so you cant mess that up,just take your time and use the right tools and pre-soak the flywheel side of the crank and spray some penatraiting oil to loosen up.and replace seals and inspect tranny bearings,easy to replace right now and forks.
