Oh well that special puller idea is a no hoper. Good luck with the repair.

Ironic thing is - went to the mechanic today - he's said yes input bearing shaft

LUCKILY! he had a bloke in 2007 who had a punto who had same problem - but the car never made it as it was wrote off

So sat there ready and waiting is a 1.2 Bearing and Seal

Okay i cant do the work - BUT Atleast the correct parts are already there

if you want ironic ism i collected a punto today and the power steering was totally non working even the city button wouldnt flash up
sorted now with another motor but i usually find if i mention something like this it normally happens to me tomorrow#

just got to find why the airbag light is on now but i guess the new fitted battery gives clues

hi guys,
i was wondering can the input bearing be changed while the bell housing was still on the car? could it be the case that i can just pop the selector housing off and then unbolt the gearbox from the bell housing, leaving me with my drive shafts still connected? from the look on the pictures there would be no need to remove the drive shafts and the bellhousing from the engine??

i got a gringing grumbleing noise. and its there when i pull of in first then goes quieter the further up the gears i go. usually cant hear it in 3rd. gets loud if i go from second to 1st.
do you think its the same problem?

one other thing am i going to kill my car still driving it like it?

thanks all

Check out the threads discussed its totally not possible with the gearbox in the car.

A gearbox with noise that varies in different gears has shot bearings that are likely to collapse. There will also be debris dropped inside leaving the differential vulnerable. They don't warn you with grumble noises, just bang and the entire gearbox casing is ripped open.

lol thanks
i thought it might be too easy. got to sit out in the rain tommorow and take my gear box out then. i wasent sure because on the pitures the drive shafts are still attached. and there didnt seem to be any need to access the back off the bellhouseing. i suppose the gearbox and bellhousing interlock the parts with each other.
many thanks for your quick reply. ile post my findings.
also over the last few years i had engine judder when driving along slow. even if the engine ticks along at the same revs . maybe this bearing had some slack in it and was causeing this?
tbh this little punto have never failed an mot and i have never even replaced a light bulb. shes been fantastic. so i cant complain . btw i got a quote for a gearbox replacement at a local garage and the lady said about a 1000quid so i kinda choked on my coffee. .ile do it my self in the rain lol.
thanks mate

Yes its possible to swap input shaft bearing with bellhousing still in the car but as White says, if there are differential bearing issues the thats another matter.

When I swapped my gearbox and clutch the last time, I'd already changed the bearing and seal before putting the entire thing back together again Little did I know but the seal was for another box and was slightly bigger. Long story short, I ended up speaking to a Fiat Tech who said just unbolt the box off the bellhousing and swap the seal, re-fit etc. It worked fine, saved a ton of work and fingers crossed its still going strong.

Bit of a tip for you, use two self tappers screwed into the holes around the seal to jack it out. Works a treat

Good luck mate but I'd def reconsider working in the rain

thanks mate.. got no choice got 3 days to get it back on the road. cant see that with new year and stuff but i gotta try. i suppose its not much harder to take out the bellhousing to . if anything else is gone i may has well replace that too aswell as i got it all apart..
thanks for your advice. this will be my first gearbox repair so it may take me 3 weeks lol

Where are you in the country please mate?

If your near to sunny Hull then I can help you

Only slightly tricky thing in taking the box off this way is the reverse selector (which I believe you can see in Mr Wilds brilliant thread) It sort of rests on a ball type of thing and you can only pop it back on again just as the box is about to meet up with the bell housing as your putting it back together again.

You'll know I'm sure but your going to need a bit of a shopping list for this job

Bearing (cant remember the number but its on here, cheap at a bearing factors).
Seal, dont get wrong one like i did (Your friendly Fiat Stealership).
Sealant (for bell housing/box joint) Check with Stealership but I used an anerobic type (goes off in absence of air)
Gearbox oil (cheaper at a factors but Stealer sells genuine stuff) Think you need just less than 2 ltr's.

Once box is off your going to need a puller of sorts to drag bearing off shaft, not expensive, I used real cheap three legged type.

To re fit the new bearing, I used a cold spray from screwfix to chill the input shaft and a warm air gun to heat the new bearing. It just slipped straight on.

I'm going to PM my mobile mate on the off chance you need help over the phone

Good luck dude.

your a gent .. thanks shaun. my plan tommorow is strip it down then bring it into the kitchen without my wife knowing,, even though shes home all day.. then look from there.. btw are u saying use dealership stuff or not too lol?
thanks for your kind response and btw im in south wales ..
cheers mate

The bearings are available as sealed for life types with integral soft seals. Leave one seal in place and pull the seal from the side which will face into the gearbox. Also use the correct seal as back-up. Belt & braces r us.

I strongly suspect parking Puntos on UK roads (with LH camber) leave the gear oil low at the clutch end so its dry when the engine starts. Some side streets with a steep camber or low gutter would be worst of all. Cars parked on the opposite camber or on level drives would be less at risk.

regulary now park mine with the passenger side wheel up on the kerb

A - because im lazy
b - Narrow roads sometimes call for it
c - To let the Bearing soak in oil while the oil is still hot
So when i pull off again, i KNOW its been sat in oil

Must admit, probably ready for a top up....

It's only a theory and not everyone agrees, but the evidence of pitted bearings on boxes with failed seals points at poor oil supply.

Hi I've just bought a 1.2 Punto that has a noisy gearbox and a worn clutch. I should be replacing the clutch tomorrow weather permitting and after reading this I have decided to check (and probably replace) my input shaft bearing and seal.
I just wondered if anyone knows of where I can get the parts I'll need as cheaply as possible without compromising quality and preferably not ordered from internet as I need to get it sorted quickly.
Thanks,
Dan

Hi all this message is to update you on my input shaft bearing change. so today i drained the oil first then unbolted the gear selector and unclipped the cables so i could get that out of the way. then i put a jack under the bellhousing near 1 of the bolts so the weight was not actually on the cast shell of the housing then i undone the bolt for the engine mount as the engine started to drop i lifted the jack to take the weight and unbolted the engine mountain off the body and off the gearbox. all was left was the gear box. i undone all the bolts around the gearbox and slid it off. i removed the 2 bolts for the folk as mentioned and 1 more thing. to remove the bearing i put a screwdriver from the top at the gear selector and tapped it out from there the old bearing was split and could not use a puller on it i followed you photos and i am thankfull for your information Mr Wild . And a big thanks too Shaun for his help. i found this job really easy without needing to remove the bellhousing drive shafts and so on.i will be putting it back together tommorow.
ile update when i put it back together if there are any issues to be carefull off..

does anyone know how wynns black gasket maker works best?? i been doing some research and some say put it on and tighten others say put it on then tighten till it starts to squeze out then allow to cure for an hour then tighten fully.. also how long after till i refill with oil and how long till i can use the car?
Thanks

ok im all up and running again now. no leaks so far ..(not to tempt fait lol) only things i can say is let the sealant cure for an hour before tightening up the gear box. and also i decided to put the sealant on the gear box because i had it out and it was easy to make sure it had a good dose but i would recomend putting it on the bellhousing because when u do the nuts up for the fork u get it everywhere my spanner got covered and so did my hands ,, so i had to redose that parts with the sealan t.
Thanks again all

looking at this guide think ill av a go

thinking of doing mine this weekend, might do the clutch at the same time.

whats the best bearings (cam shaft/oil seal) from ebay, or is it worth going my local factors and getting them?

Cheers
paul
