Installing a MML
 
Hello.

I ordered the Currie 1" Motor Mounts.
How hard is it to install them? Can I install them with my standard tools?
Is there a problem with my A/C?
Btw. IŽll install it together with an e-fan.

Thanks in advance.

Am I missing something....I thought the MML was so the fan didn't hit the fan shroud, so...if you are installing an E Fan, doesn't it come with it's own shroud..?

slf41002 06-28-2008 09:13 PM

Yes the flex lite fan he is getting has its own shroud but I figure he is doing a MML to help with the drive line angles.....

@rthdtj:
my 2" BL came with 2" fan shrould lowering brackets. thatŽs why i didnŽt need a MML.


@slf41002:
yes. i want to get rid of the 1/3" TC drop. and i also need the MML for a belly-up skidplate in the future.

MML is not that difficult.......just the driver side is a PITA. I had to take the whole bracket right off the engine (3 Bolts) and snake the bracket and mount (together) out. Then separate and install new MM on the bracket....snake it back up in there....(don't tighten the MM on too much, it's helpful to have it bend while getting it back up through the steering/suspension)...and Done.

i installed the jks budget mml.. it was pretty easy.. used a floor jack to lift the motor up.. put a piece of 2x4 on the jack so it wouldnt mess my oil pan up or dent anything..

the only thing i ran into was cutting the original motor mount but you wont have to do that..

Try to check out this link: http://www.4x4xplor.com/MML.html
This gives you some guidelines and additional information on how to install MML properly... :crash:

The MML was the hardest job I’ve done on my Jeep, yet I thought it would be the easiest. Towards the end, what really helped me was installing the mount’s cross bolts the opposite way, so I could get better access with a torque wrench upon reinstallation.

aside from cutting the drive side bolt that holds the mount on the block to the mount on the frame...it was fairly easy i think it was a just little harder the bl

If you are just putting in the MM spacers it should be a pretty easy job, the hardest part is getting to the bolts, make sure you have plenty of extensions for your ractchet.

As mentioned, loosen the bolts, put a 2X4 on the oil pan, jack up the motor, insert spacers, lower motor, tighten bolts.

Should take you about 1 hour or so. PB Blast the bolts every day for a few days to help get the bolts loose.

Hope that helps.

NY94YJ has it right, remove the entire drivers side bracket from the block along with the stock motor mount. Then with the bracket on your work bench remove the old stock mount and instal the new one onto the bracket then bolt it back up to the block. The currie mml doesnt involve spacers like some of the others like the JKS. The Currie is similar to the MORE and DAYSTAR motor mounts.

I've kept my writeup from when I did the daystar mml install (exactly 4 yrs ago yesterday - July 1 2004). my grammer and spelling aint good but I think it still makes sense.

----------
i just finished the motor mount lift and body lift last night.

THe motor mount I did first and took a little over an hour. I kept hearing about how much of a pain it would be to install but it was really nice.

For the drivers side motor mount:

- the first thing I did was loosen the tranny mount bolts under the crossmember.

- Then I unscrewed the fan shroud from the radiator.

- Then I supported the engine using a hydrolic jack under the tranny bellhousing.

- unbolted the driver side mount from the frame

- I then loosened the nut and long bolt supporting the engine bracket to the engine mount

- Then from undernieth I removed the three bolts holding the engine bracket from the block.

- I took the whole thing out and removed the long through bolt and attached the new mount to the engine mount bracket.

- Then after jacking the bellhousing up another inch I took that whole thing again and put it back in reverse order. It was a snap. no problem at all with holes lining up.

For the passanger side motor mount:

- I kept the hydrolic jack lifted where it was from before.

- unbolted the mount from the frame

- removed the long through bolt from the mount and engine block bracket.

- put in the new mount and loosly put the bolts in through the frame... didn't put the nut on yet though.

- then I raised the jack just a bit to line up the engine bracket bolt hole with the motor mounts hole for the long "through bolt"... this was the only "tricky" part if you can call it that... use a long screw driver or some pry bar and lean the mount a bit so that the hole lines up with the engine mount bracket hole.

- once you get that bolt in then its time to tighten it all up.

- lower the jack

- tighten up the bolts under the transfer case

Then after doing the body lift its time to put the shroud back on.

Its really quite easy. have fun and good luck.

I changed my order from the currie 1" MML to the JKS 1" budget MML. The installation of the JKS MML seems to be easier.

IŽll remove the stock fan shrould and the stock fan at the same time and install am e-fan instead.

MoA 07-07-2008 12:22 PM

you got to cut the existing motor mount's bolt to fit it inside the extension for the jks mml.. FYI

nicolas-eric 07-09-2008 08:32 PM

actually i have about 4-4.5" of lift with the stock driveshafts and only a .25" TC drop with some washers.
can i lift my TJ a bit more with the 1" MML without some vibes?

slf41002 07-09-2008 08:49 PM

I wouldn't try it.You are going to run out of travel on the drive shafts the wheel base is going to be way to short with the stock arms and it could cause all kinds of problems.You could throw in some BB spacers to see but that means taking them back out if it causes problems and it may even cause you problems that brake or twist something.IMO i would leave well enough alone.:DYou have been lucky enough so far to have the height you have now with no vibes and just a quarter inch of TC drop.P.S I only have a 4" suspension lift other than the 1.25 BL and I have a 1" MML and a 1" TC drop.BTW the MML is not all that hard I done mine by myself in about an hour.

nicolas-eric 07-09-2008 09:00 PM

i already have 2" spacers abovee 2.5" OME springs.
iŽll install some other things in august. perhapos teh rear sags a bit more with the heavy rocker guards and rock crawler rear bumper. then iŽll make some bigger rear spacers on a friends engine lathe to get the height back..


after the last weekend in an offroad park i want as much ground clearance as possible.

but perhaps your right and i should leave it like it is. then iŽll add some extra height in the autumn when i install the belly up skid and the SYE and CV driveshaft.
