Technical Punto for spares and question about oil pump removal

[joncoxon]

Afternoon all, I have a punto 2001 1.2 which I'd like to remove oil pump from. Ive an assessment on Tuesday on this and been practising on my punto as she's not working Engine does not start. I cannot remove the bolt that is shown, it holds crankshaft sprocket on. just wondered if anyone knows how difficult it should be. Bar some very rusty bolts on manifold and a ruined sump it came apart ok up until this point.


its my practice car for College just to pull about so will still need the wheels attached but some bits will become available over time if people need. I'll try and remove any other items as quick as possible, I get between 0 and 1 day a week free so times limited. trim parts mainly for now, and depends how bad they are. The car externally isn't great.


I am happy to get pictures for people and I am there tomorrow


The funds are going toward getting another car to practice on, one without so much rust.


Kind Regards
Jon

There are two ways of undoing this bolt.

Option 1 remove small round cover on the lower part of the flywheel cover and have a assistant jam a pry bar into the teeth on the flywheel. Now use a long breaker bar to undo the crank bolt. I used a jack handle to extend my breaker bar as the bolt should be very tight.

Option 2 take a length of flat bar and drill a hole in the end and anouther 10 to 15 cm further down. Take a shorter length of flat bar 10 15 cm long and drill a hole at either end. Bolt them together in a y shape and attach them to the pulley holes in the crank. You can now use this to immobilise the crank whilst you use a breaker bar to undo the crank.

This style of oil pump is now almost impossible to get hold of so keep it safe.

I struggled badly whenni stripped my old knackered to gey that bolt out

So much I actually sheered the wood rough key

You need an good impact to get that ****er to move im affraid

Thanks for reply, we immobilised the flywheel and used a longish bar, got a bigger one to use tomorrow. as couldn't get the force that was needed on it.
Luckily the rig on Tuesday will be a lot easier as they're not torqued to much

I must have been very lucky when I undid my crank bolt as it was not too bad and I was working solo. Or it could be that my breaker bar is about a meter long so you get an awful lot of leaverage on it just have to be very careful not to snap the bolts.

 

[joncoxon]

Will attempt again tomorrow and see, would be nice just to say I could do it its never going back together again anyway

 

[varesecrazy]

working solo, I would remove a spark plug and feed nylon rope down, that'll get all squashed as you turn the crank..,
and jam the lot, while you only need to swing on the 1 spanner then..!!,

where is this parts car based..??

Fortunatly have college mate working with me, larger bar tomorrow.


Its in Lowestoft, its car to learn from but its apparent it wont be feasible to repair, will carry on messing with it until I source another

Easy peasy way is just to make up a flywheel locking tool that bolts on to the grearbox casing. About 20 minutes work with a grinder, drill and welder. In the past, I've used a leg off a very small 3 legged puller, spaced out with washers.

If you pop the spark plugs back in, you should be able to free the bolt with air gun, without a locking tool.

Trying to free the bolt off with the cam belt on will often result in the faux woodruff key in the (probably sintered metal) pulley snapping off. They're very fragile.

we hijacked the starter motor and used that to spin the crank and we have success, all that just to ay I could do oil pump removal. well was good learning and assessment tomorrow


thanks to all involved with advice and pointers. Its so nice to have helpful people

cranking an engine will no oil feed to loosen a bolt

Good job its a dud engine eh

indeed there, the cars going to serve its purpose well, and has been. I's she was a runner then I'd have taken more care, we put pump back on and off and on a few times as practice, also whipped head off just to have a look.


I think the college rigs have more chance of living than this lump personally, but I've had fun retiming and so forth. No doubt it will all come apart again in future to practice the next bit

The good thing about rigs / college cars is you get to see alot

I did my 3years not long ago, and i did alsorts of Heads and belts and pumps and this and that

As I'm over 18 I only get 3 hours in workshop a week, I needed more time so have this. I'm just lucky to have found it really. Good for gathering evidence for portfolio too

Wow only 3 hrs.....
I got a whole day 9 -3/4

And 2full days thoery

 

[joncoxon]

I'm on the imi level 2, get 2 days theory then just 3 hours, spanner time, well more like 2 when we've sorted out the ones that are late and mess about. since, Fridays practical I've spent over 15 hours taking apart and putting the punto back together. Same thing over and over, Taking pictures, learning. The course was meant to be 50/50 split theory/practical so bit disappointed
