Replacing front crank seal and fitting speedy sleeve to hamonic balancer

[Day-mow]

Hey I'm gonna do this on the weekend well have a go anyway. Just wondering if there are any tricks I need to watch out for. Dad flips out about the possibilities of things going wrong. Another friend said it's an easy job and will take a hour to complete.
So I'm a bit lost but still up for the challenge I'm sick of the oil leak

I replaced the harmonic balancer on mine, with a brand newy cost me 120 bucks.

Best way to get to it would be to remove the radiator and thermos and possibly the front bar, so you have plenty of room to move about and you can see what your doing

Then you will need to find a way of stopping the balancer from moving while you tying to undo it, either get some one at the bell housing with a spanner or something to jam the fly wheel so it dosent move, unless theres a locating hole u put something trough which holds it.

[frd906]

Also isnt there a difference between the speedy sleave, as that actualy goes over the shaft to prevent the harmonic balancer from having to much play, not to actually seal it,

You need a front main seal, which is only around 12 to 15 dollar mark.

But yeh if you plan to do the sleave as well get a seal as well,


I think theres a thread some where ill search for, been awhile since i did the balancer

WOOPS, i just rememberd you will also need a HARMONIC BALANCER REMOVAL TOOL, to get the bugger off,

Its like a 3 prong thing, the prongs sit in the small groves or slots inside the hamonic balancer and you have a sliding handle. so when you pull the handle back towards your self, the balancer should start to come off, or just use a rubber mallet or something a little more sloid and just slowly tap the balancer for each side and that should do it as well, Slowly lol

[Day-mow]

Yeah I have the seal already. And I have a balancer removal tool so. I'll see how we go.
Luckily I've got a 2nd car so if I run into problems I'm not stranded

So a speedy sleeve may not fix my problem?

[frd906]

It will fix it for a while, but it will prelong the life of the balancer for abit longer,

How much movment is there?

If i was you id replace the harmonic balancer while its all apart, so you dont have to do it a second time down the track

While removing the harmonic balancer, if you find you can't get the nut undone, put a socket on it, with a breaker bar leaning against the passenger side chassis rail. Quickly turn it over and switch it off (don't start the car), and it will crack the nut. I know it sounds dodgy, but it sure as hell works!

You sure it is the seal is leaking it might be chain tensioner behind
the power steering bracket.if it is a 6 cylinder.

[Day-mow]

Yeah I'm 98% sure it's the balancer. I've herd that's how to crack the nut so I rekn I'll give that a go.
Sounds like a speedy sleeve isn't proven I'll get a balancer.

Im feeling pretty confident. I've knocked off work early so I'm gonna start this arvo.

What type of puller did u guys use? Every puller I've tried doesnt fit. The big 3 claw type won't fit in because my ac condenser is in the way. Suggestions?

[frd906]

We tried using that one on mine but in the end we used a hammer and slowly tapped it off

[Day-mow]

Didn't want to hear that hahaha. Long screw driver?

I used a small 3 jaw puller from supercheap, but had to 'modify' it slightly by grinding all the edges down so it just fits into the balancer. Cracking the bolt with a breaker bar or torque wrench resting on the ground works suprisingly well.
You only need to remove the intake snorkel and thermo's.

Don't use a screwdriver or any other lever. You'll end up pushing and cracking the timing case, big trouble. The genuine puller has special bolts that slot into each posiiton behind the pulley. I made my own puller, using the new pulley as the template. I think 10 mm diameter bolts (16 mm head) were a good fit. Just drill the right bolt holes in a bit of steel and slowly do up the bolts evenly. It was bit fiddly but then you only use it once.

umm my old balancer never had the location holes nor did my new one

snap.. im getting a large puller from my dads it should be here 2morro evening. i rekn what i'll end up doing is putting that in and cutting the thread so its short enough to fit in with out taking out the condenser.

if it needs to be trimmed on the claws i guess i'll do that to

[AMB]

Not holes, the long curved slots, if you look at the back, you will see where the bolt heads sort of locks in. First the bolt head inserts in the wide part of the slot, you move it along the slot and then twist and engage it in the narrow end of the slot (hard to describe, but you need to shape the bolt head to make it work properly). I just copied one I saw somewhere.

[Day-mow]

the slots that are right next to the centre? you couldn't get an ant in there if you lined it with honey

[AMB]

The slots are made for a puller.
Like I said, if you look in from the back, you will see where the bolt heads or special shaped puller fingers are suppose to lock in. Buy a new balancer, then buy or make a puller that fits it.
If you pull on the outside pulley part of the balancer using a standard puller, you will distort and tear the rubber and ruin the balancer, which is alright if you are replacing it.

[Day-mow]

Sooooo because I've brought a new balancer what you posted isn't heaps important

[frd906]

if you cant get it off even with a puller, just uses a rubber mallet, fairly sloid one and slowly go around it tapping it out,

[Day-mow]

Pretty sure I'm going to be doing this anyway. I have a new balancer so I don't ry care what happens to the old one. I was told to be careful of the bearings tho if I chip it out

Yeh, If you can find a puller that is wide enough to fit on the outside of the balancer, and short enough so that you don't have to remove radiator and condenser. Unlikely. You also need plenty extra room to withdraw the balancer off the shaft about 50-100 mm.
You can't go slowly around it tapping it out, there is an engine behind it. And of course the fit on the shaft is very precise and very tight, so the balancer has to be pulled off very evenly. Don't be tempted to try and lever it off.
And don't forget to put some sealant on the keyway when you install the new balancer. Enough said. Good luck.

[AMB]

Hic, double post.

[TTXF]

you need a small puller like this one, small enough to fit in your hand. The three 'arms' fit into the 3 slots on the balancer. Use your new balancer to work out how it fits.

[Day-mow]

I have one of them

[Day-mow]

Ok so I have my 150mm puller but I can't get 3 jaws on it anywhere unless I take out th crank angle sensor. If I take this out is it going to cause any major problems or anything like that? Are there any tips I need to no about taking the sensor out?
If I can get in there I think I can get it off.
I'm to scared to leaver it off because I'm scared I'll crack the crank case but I think that's the 2nd most effective way.

Also looked on the back of my NEW balancer and there isn't any type of groove can get a photo for proof if you really want.

[JK EX CHASER]

Remove sensor just in case you might pull the balancer out on a angle and damage it.

[Day-mow]

Yeah removed that. Balancer is out but.


I broke the TDC marker. This means engine out and new crank case on yeah?
