Removing Flywheel, last thing I need to do before I send off the core...

I was told is was a 35mm, is this accurate?

Let me know..

Thanks

sounds right - i think a 2 1/4" or 2 1/8" also works

 

i need to be sure, cause i've seen people saying 52mm, 54mm, 32mm, and 2 1/8"

 

Search!! 54MM which is the same as 2 1/8" I believe

 

2 1/8 works fine. The metric socket is hard to find and $$$. The 2 1/8 is around 10-20 bucks at napa or =.

 

lol def bigger than 35mm...its a 54mm or a 2 1/8...i got a 2 1/8 because it was cheaper and sears actually had one in stock.

 

I got the metric socket at Sears. Used it once and returned it. I think it was like $80.

I used a 2 1/4 and it semed like 2 1/8 would have fit like a glove but the 2 1/4 worked great also

 

2 1/8 is the size & they have a 3/4" drive 2 1/8" socket at sears. But you have to have a 3/4" drive to use it.

OR get a reducer, but I wouldn't suggest that. I'd suggest getting that 3/4" drive slider bar, that's what I used, worked good.

 

Here's the bitch now... looks like the previous owner didn't know how to drive stick, look at the flywheel thing has hot spots all over it... tsk tsk tsk..



anyone know if they make an electric impact gun that can do 500ftlbs or torque?? ELECTRIC!

 

I don't think you will get it off with an electric. Its a 2 1/8 nut (54mm), for sure as I have the socket in my tool box.

Its much easier to just impact it off and on, using a good air impact that has adjustable forward torque. They are very common, usually with 150ftlbs - 300ftlbs - 600 ftlbs settings or so.

Don't forget the sealant on the nut itself when you put it back on!

mine was a 2 1/2 inch. i had to search for 3 days to find one locally. spent $50 on the socket and a breaker bar

 

The one holding the front pulley on is actually harder to get off due to the larger surface area of threads coated in blue loctite. Crack this one with a breaker bar first (but do not remove yet), then use a 2-1/8th socket to remove the flywheel nut. You'll then need a puller to get the flywheel off.
If you're not tearing the engine down, leave the front pulley bolt as is.

 

ugh.. get yourself a LONG (like 4 feet) piece of angle iron. Line it up with the flywheel holes, and drill 2 holes through it. Bolt that sucker to the flywheel, and set it on the ground.

Now, go to sears and get a 2 1/8" socket (it's a 3/4" drive I believe), and that 18 inch or so long "breaker bar" that slides along the bar.. it's kinda hard to describe, but when you see it you'll know.

Set that piece of angle iron on the ground, and attach the socket to that breaker bar. Put the sliding wrench thingey on the flywheel nut, and STOMP on the sucker. Worked for 2 flywheels for me.

 

Its a nut, not a bolt. You still need to get the flywheel off afterwards and it's a biatch!

I have a fat azz snap-on socket that worked great think its 2 1/8. Took that nut off in just a few tries with the impact.

 

*Forget* the breaker bar...

Unless that is the only way you can do it, I strongly recommend just using an impact on the nut, it will make your life alot easier, and you don't even need to hold the flywheel.

To get it off, I didn't even use a puller. You can wedge a small peice of wood between the rear housing and the flywheel (gently, just enough to give it some outward force) and hit it around the edges with a *rubber* mallet. Move the wood, hit it again, and it will come off after repeating this procedure a number of times. This works, I have done it several times.

Also, assuming the pic is still correct and you have the engine out of the car like that already....A breaker bar and all that will be nearly impossible to use, and the engine will move also....

...impact impact impact...air tools are life man.

Yup, air tools are by far the better and easier choice. But failing that, a breaker bar will get the job done, albiet with more difficulty.

 

It will be really hard to use a breaker bar without the engine being in the car. Take the engine to a mechanic with an impact gun.
