Replacing clutch dog 25hp 'rude ????

[spareparts]

if its a real salty unit, you're probably better off finding another unit( you tear it up trying to get it apart), if the gear lube has a lot of metal in it, gears and bearings are probably shot. Is it jumping out of gear? or just not going in all the way. The old timers used to pull the clutch and flip it over, figuring reverse doesn't get used a lot. Try and find a diagram or break down to get a handle on it before you start. Is this the one that the shifter rod goes thru the water pick up?
