Rear Oil Seal

[leeroy_25]

I have oil leaking from my rear enigne oil seal causing clutch slip. Can someone tell me the part number of the replacement seal(s) I require and may be the best place to get them from? I am slightly under the impression there are two seals to be replaced?

Thank you

1668-10-556A Is Mazda part number. I would think any vendor would sell it. You could get it from any Mazda dealer but it would probably take about 3 weeks lol.

Thanks Phil,

Is it just hte one part that needs changing then? no secondary oil seal of any type?

there is a secondary seal that sits around the rear gear.

[leeroy_25]

Around the rear gear? is there a plate you need to remove to get at this?? Have you got a part number or pic of this?? I have seen two types of seals but the description is not specific to say what it\'s for! Has it got a metal collar on it?

Thank you

Hi,
I suffered the same problem. There is a seal and an O ring.
 
Main problem is the 54mm socket required to remove the flywheel.
 
Also I think the O ring is behind the housing that supports part of the inner engine, and if removed without support will require an engine rebuild.
 
I took mine to a Rotary specialist who did the job.

you need to remove the rear gear. this will not damage the internals or require a re build.

[leeroy_25]

Blimey!! That had me going for a sec!
So Dave, I remove the flywheel.. then I will see what exactly? What is the rear gear you are refering to? Is there a cover plate on the back of the engine with a drive gear for something inside it? Is it all pretty straight forward an self explanitary when you are there?

Thank you

remove gear box, then remove the clutch from the fly wheel. you will then need to lock the flywheel in position so that you can undoo the 54mm flywheel bolt to remove it. then undo the 6 or so 12mm bolts and pull the rear gear directly off the back of the engine. you will need torque wrench etc to re torque the bolts you removed and a clutch alignment tool to re allign the clutch.

[leeroy_25]

Thank you for that Dave,

Do you know the torque settings or can you point me in the direction of a manual where I could find them?
What\'s the best way to lock the flywheel? Has it got a locking point in it?

Thank you

here you go fella. i have just stripped my spare engine and i took step by step photos. might help so you know what you are looking for.
 
having removed gear box and clutch this is what you will see. in the center of the flywheel is the 54mm nut you need to remove.

 
once the flywheel is off this is what you see next. remove the key from the shaft.
 

 
you can then remove the rear main seal.
 

 
to then remove the rear gear you need to remove these bolts.
 

 
hope that helps.

Quality help mate.. than you very much!
Oooh.. Where can I get torque setting for putting it back toegther and is there a sequence for doing the rear gear ones back up?

Lee

[leeroy_25]

Dave or pigeon,

Do you happen to have a 54mm socket you could lend me or sell em to remove my flywheel? How did you get the bolt undone a torqued back up? did you just use an air gun. Mine is rated to about 350-400ftlbs torque. did you need a proper impact socket or manage to get away with a 12point standard one?

Thank you
Lee

i would suggest not using a 12 point socket - if you round the nut then you will find yourself in a whole new world of trouble

i always use 6 sided ones now - better safe than sorry

http://www.mazdarotaryclub.com/forums/showthread.php?t=51092&highlight=54mm - have a look here for a cheap one ( not sure if its 12 or 6 sided though )

12 sided wil be fine, its a big nut.
Change the oring on the stationary gear, could do gear bearing aswell if necessary.
