670 Engine question

[Murminator]

Ok major oil leak between the halfs of the case, engine is out does the mag and clutch have to come off to split the case? cause the mag it a PITA to get off so it's still on and the case won't split bent the starter pulley using a pully puller on it . Left the top end on also except the head cover wanted to see the how the pistons/cylinders are doing. Anything else shoud be done when the bottom is apart? sled only has 3K on it



*edit* found a schematic the shows a plate behind the mag....any idearers how to get the mag off?

To split the case you need to pull the mag. off. Undo the big nut and use A steerning wheel puller with three metric bolts. ( you might have to heat the center to brake the bond, not to much heat .This shaft is tappered and has a woodruff key to hold the mag in place. Under the mag is your stator. there will be three bolts holding the coils in place. remove the stator * do not unscrew your pick up ( a little magnet thingy screwed dowm to the top of the case) otherwise you will have to regap / time it. once you have all you base bolt and case bolts out it should split.

have to remove pulley, remove 32mm nut, bolt puller to flywheel and pull off. stater plate is in behind held on by 3 allenhead bolts. should pull off clutch clean very well, new seals, maybe check crank bearings tim

I forgot to mention you will need to remove the rotary assembly on the front. ( carb. side ) This also holds the upper and lower case together. You will need a degree wheel to re-time rotary valve (thin metal disc.)
