Technical  Oil seal


Not that straightforward

Use a heavy grease on the back, if the spring pops off because you have to tap it too hard, you'll be doing the job again in a few months


I never tried freezing the seal, but should work

I get just violent and yank them out if I was to start my tool kit again I be tempted to buy the tool in the link

The shaft wears down a little over time it's worth tapping it a little short so it runs on freash metal
 
Airbox
Drivers wheel
Auxiliary belt
Auxiliary pulley
Timing plastic covers
Your suppose to remove the the timing sensors, I don't.bother the covers come off without if your carefull
Timing belt
Timing pulley

Basically if you've done the timing belt it's the same job plus.a couple of extra steps

There is a special tool

1.870.744.000

s-l1200.webp


To hold the pulley while the bolt is undone

The bot is very tight

20Nm + 90°


Most bolts that are tightened to an angle should ideally be replaced, I don't see it as a requirement but I would replace it

Seeing as the gearbox is still fitted you should be able to put iin gear and get someone to put there foot on the brake to hold the flywheel still,.instead of the locking tool

Just be very careful to apply the bakes firmly so as not to allow the car to roll and pull it of the stand

@AAB1992 is still active on this forum, maybe they could chime in with anything I have missed
 
Thanks for that,I have in the past replaced the belt and the front camshaft oil seal on two separate occasions. I'll pobably get it over the pit first and slacken the bolt whilst both wheels are on the ground in gear and handbrake on.
 
Sounds like a good plan to me

Reading through the list of operations again

I think you can leave the air box on, I don't see what access it gains you
 
The only concern I have is if the bolt is a right or left hand thread I was reading one of you post's from a few years back which you said there were 3 different sizes of bolts and some were left hand and some right. I will use the original bolt and use thread lock, that's if I can find out which way to undo it. :unsure:
 
Correct both are used

VVT engines are left

Older engines are right

My feeling is at 2004.will still be conventional, most engine changes were in 2009 and 2010

Wish I could be 100% sure

@AAB1992 did one on the same year, hopefully they can advise, @irc has probably stripped them down for spare parts so may have a better idea at when the crossover occurred

Shame car makers don't mark there reverse(left) thread like most makers do

I think the crankshaft pulley bolt changed pretty early on, maybe 2005-ish, and then stayed the same possibly until the end of FIRE production,
but its been a while since i took one apart.
From notes, an 04 used part 7766581 and an 06 used a 46778599, and the 46778599 was also used on the 500 at least as late as 2013.

Oh dear that even more confusing it might be possible for the 1.1 and 1.2 to be different

7766581 appears to for the camshaft

Eper doesn't often specify left or right which is annoying

Elearn shows only specifying right for panda which we already know isn't correct

Well spotted... i have 2 bolts listed in my notes for the 04 rebuild, so I suspect i had to replace the camshaft bolt too. If so, the other one was apparently 55192920.
Either way, pretty sure the crankshaft bolt was different between that engine and the 06, which I worked on at about the same time. I do remember there being a few annoying little differences between the two at the time, and correct information being hard to get.

Do you mean it changed from right hand to left in2005.
 
We don't know for sure, I don't know anybody that does, 2004 it's likely.to be conventional

It's possible if the change is around 2005

It's the new evo2 block.with the round oil filler is the swap over point,.but that's a pure guess

You could try the technicians at a dealership

It's hit and miss, just been to a nissan dealership
About some Suzuki parts yes I know but the alto and pixo share the same platform,in Crewe they were very helpful and gave me print outs with part numbers

But when I try to get some information from a Volvo dealership I got blanked

Another option is to put you VIN into eper and find the part number of the bolt fitted

We can then cross reference it,

@AAB1992 is still active on here. They did the job on a 2004 1.2 so hopefully able to give some feedback back

It's not common to remove the crank pulley do we don't have many data points like I think aab1992 might be the only one in the last 8 years on a none vvt engine
 
I've found this.
For the 2004 Fiat Panda 1.2 8v, the crankshaft pulley bolt is a standard right-hand thread. This means you should turn it counter-clockwise to loosen it.

Key Details
  • Thread Direction: Standard (Right-Hand).
  • Removal: Turn counter-clockwise to remove.
  • Socket Size: Often requires an E18 Female Torx socket for similar Fiat 1.2 8v engines.
    YouTube +4

Important Considerations
  • Do Not Confuse with JTD: While the 1.2 8v uses a standard bolt, some other Fiat engines (like the 1.3 JTD) may have specific components with left-hand threads. Always verify against your specific engine code if you have any doubts.
  • Torque to Yield: Many modern crankshaft bolts are "stretch bolts". If the manufacturer specifies that it is a torque-to-yield bolt, it should not be reused.

Always consult a verified service manual (such as Fiat eLearn) for the exact torque specifications for your specific engine code.

The oil seal came today, it looks a bit on the small side to me but not having the old one off I can't make a comparison. The external diameter is 37mm internal is 26mm and thickness is 7mm all sizes are taken with a ruler.

More confusion regarding the bolt thread. I rang a local main agent and was told it was a right hand thread then a couple of minutes later was told it was a left hand. I phoned a local Fiat breakers and was told it was a right hand thread. I then phoned The Fiat Workshop Royston and they said they didn't know.
So any info on this will be appreciated.

Ps Does the picture I posted above of the seal look the right size.
Thanks.

I have the part No for the crankshaft bolt which is 7766581 I've tried entering it into ePER but nothing happened, it's probably my fault as I don't know how to use the system can anyone help please.
