Any Mitzi L200 Mechanics (Need Advice Please )

Recommended Posts

Crank shaft pulley wheel came lose , but it wasn't the bolt . It was stripped down and found to be from inside the sensor blade , had been worn away , and so had the round big washer

 

All new parts were bought and when being put back together , it was found that the wood ruff key when fitted was not a tight fit, and loose , any it was put back to gether, and worked grand for 3 weeks , but nowthesame has happened again ,

1. Should the woodruff key be a tight fit ,theres more than likely enough room for two in the crank slot

2. Or is it a new crankshaft ( God forbid)

Any help please lads

The woodruff key should be tight enough that you have to tap it in with a hammer. If it's loose it defeats the object of locating the pulley in the crank. I wouldn't think you'd need a new crank. They must sell bigger woodruffs?

waste of time looking for a larger key, the slot it fits into is going to be worn, either new crank or if you have a very good machine shop they could weld up the slot and recut it, whichever way you go the labour charge is going to be on the bad side of ouch

Get a bigger key made, they can broach the slot of the pulley to fit the new size key.

Seems very cheap to me mate,I use a fella called Roland if you google Mitzi heads he might be able to help very knowledgeable on these engines.

Good luck

the pulley and key won`t be the problem, the slot in the crank that the key fits into will be damaged, if your going to piss about bodging it you may as well just weld the pulley straight onto the crank

I'm been told that the welding up,of the crank can be done , but accurately cutting the slot out is not a easy task to be done

And so me are saying , strip it down and use liquid metal around the wood ruff and slot

Would some body please tell me the Best way forward

I know fec all about mechanics, but if you want a building dropped to the ground im your man , lol,

that`s why they want £500 to do it, probably done a few so have got the times down a fair bit, any here that say it`s too expensive have no idea of the size, skills needed or machinery required, if they are warranting their job for 12 months go for it, if you just want to get rid weld it, few spots inside, grind it flush and stick a bolt in it to hide it

dave , liquid metal the key in place and locktite the pully to the crank , make sure all the parts are metaculousy clean and use a new bolt , in a lot of motors the reason for crank / key wear is the bolt stretching , make sure the timing belt is good , atb
