Title: FSM in Australia
Post by: aircobra on August 02, 2012, 12:41:00 PM
going to post some pics in a sec.
bodywise, the car is very clean, although it looks like it had a respray at some stage.
that would be because i live in the driest country on earth and the country with the highest UV rating. basically the car runs well, but the comp is 75/85
so what needs doing?

so the plan is
ENGINE
1. drop the engine/tranny for ease of working
2. rip the head off and get rebuild
3. replace the tube seals
4. check the surface of the cylinders. if ok, i'm going to leave alone,if not will do new rings
5. sandblast sheet metal and paint, they're in bad shape - no paint left at all. she must have run really hot
6. replace the inner gearbox seal and gearlever seals
7. put it all back
SUSP
1. Get the klingping re-done( although people tell me the 126fan ones are pre-reamed)

pstonns ok, but looks like scuff marks on the side - is this common?
(http://i1249.photobucket.com/albums/hh512/progenysw/Melbourne-20120805-00093.jpg?t=1344164258)
(http://i1249.photobucket.com/albums/hh512/progenysw/Melbourne-20120805-00094.jpg?t=1344164309)
signs of leaks at flywheel - not sure if its the crank seal or the trans shaft
transmission cleaned up ok,

so the original plan is in motion
1. off to drop off the block for a dip and a head for a rebuild. alan will also do the measurements and let me know if i the cylinders need boring/honing and crank grinding
2. taking the sheetmetal to the sand balster
3. finalise the order from 126fan and wait 3 weeks

Looks like it is coming on really well. (I do feel for you waiting for parts though).

found a chain link in the sump ( one of the funny hook ones that are on the outside of the chain). is this a sign that the chain is about to go? it was quite loose - probably 10mm of play in the middle
the manual doesn't say anything about the required specs
and i can't find info on when these should be replaced. although the car is showing 65000ks, looks like it has had a very hard life.
i know in my bmw's, chains last 200k+, but this one looks quite skimpy
any suggestions?

The hook shaped bits on the outside of the timimg chain are self-tensioners. Sounds a bit dodgey if one has fallen off . Look inside the timing chain cover for signs of the chain touching the casting. If it is then you know it is shot.

Good luck with the project.. You are going to need it  :D My car was supposed to be ready spring 2012 but it wasn't  ???

It's very odd that these engines work still even though bearings and other things are not anymore at their best condition. Nice project though! Keep on sending us updates and pictures  :good:

Ok, now onto the g.box
wasn't hard to get apart, except that i had to buy 12mm alen key and a #4 impact driver. the only reason that i did is becuase the mechanic spotted a fragement of a bearing when he was changing the oil. so i figured easier to do it now
(http://i1249.photobucket.com/albums/hh512/progenysw/fiat126_gearbox/Melbourne-20120811-00114.jpg?t=1344682111)
(http://i1249.photobucket.com/albums/hh512/progenysw/fiat126_gearbox/Melbourne-20120811-00124.jpg?t=1344682089)
damage report
1. the mainshaft bearing has a busted race
(http://i1249.photobucket.com/albums/hh512/progenysw/fiat126_gearbox/Melbourne-20120811-00118.jpg?t=1344682202)
2. i think these are the 1st gear - spots the small on the main shaft and the big one on the pinion shaft. if you look carefully, you can see the burn marke on the small gear and the rounded edges on the big one. all gears were fine, but a bit crunchy on the 1st and reverse
(http://i1249.photobucket.com/albums/hh512/progenysw/fiat126_gearbox/Melbourne-20120811-00121.jpg?t=1344682295)
(http://i1249.photobucket.com/albums/hh512/progenysw/fiat126_gearbox/Melbourne-20120811-00122.jpg?t=1344682300)
everything else looks OK
so to all the g.box experts
1. should i get a new mainshaft (80E from 126fan) and or not bother? looks like the edges of the teeth are meant to be round, not pointed, so not sure the wear i'm showing is a problem
2. should i change the rubber boots at the same time, they look in good nick?
obviously i'll get a new bearing
thanks in advance, stay tuned

back from sandbalster ( bargain at $80) decided to go with flame proof, given the heat generated in the bay

here are the videos of the finished product. the timing was off by about 5 degrees, so that fixed the backfiring

Congratulations!! The car looks great and the engine sounds quiet with good acceleration. Are there many 126s in Australia?

I am in a similar situation. I am restoring another 126 Bis, but using another Bis as a donor car.
