Re: Project: Double Ugly

The 2.4JTD is way too heavy (hell, the 1.9 is quite bad enough as it is). I reckon the 150bhp 16v is the way to go. I've been encouraged by finding out that the front track for the Multipla and the 147 are only a couple of mm different so I'm surprised that there's such a difference in the strut top centres.

I thought the Polish guy said that the ECU isn't tied up with the BCM, which makes things a lot simpler? Or was that the 156 as you mentioned, so use a 156 ECU for the 147 mechanicals!? Need to dig back through the threads.

I wonder if it would be simplest to take the whole 147 subframe, engine, 'box, wishbones, uprights etc (with the possible exception of the steering rack), graft the 147 turret tops into the Multipla and the box section that's on the back of the 'pla subframe onto the 147 one? Are you certain those dims between strut top centres are correct?

Mmmm.......

WMF, yep those dimesions are correct but approximate. The Alfas strut tops are completely different and look to be pointing inwards slightly. The Multiplas are much wider apart. Perhaps I can take some more photos with a stick for scale or something - I'll have a think.

Re: Project: Double Ugly

No - that's fine! I just wanted to check that there wasn't a typo.

It may have something to do with the eccentric mounting of the springs that the Multipla employs.

The 147 has funny strut tops to accommodate a casting that sits on top of the struts that provides the mount for the top wishbone.

Re: Project: Double Ugly

Hi gang,

Started on the timing belt / water pump saga.

Hit a brick wall. This appears to be a t60 torx head bolt. Does it definitely need to come off to remove the top engine mount to release the belt or is there some Houdini routine I dont know about?

I found this image which suggests you do need to remove it.

The tool I need is apparently a M12 star bit. I'm going to have fun today trying to find one.

Re: Project: Double Ugly

Summat that didn't make sense last night was the auto tensioner position. The correct procedure is to tension it to the max, 2 revs then set to a hole on the top of the tensioner bracket.

Photo below shows how I found mine. Looks to be on the lowest tension setting!

like my jeans during most of the job, the belt is showing lots of cracks too.

Re: Project: Double Ugly

Little more progress last night. Ended up getting a T55 Torx bit and the offending top mount bolt was removed easy enough. There is no visible mark on the casing for the crank to be timed to, but the tool I bought does seem to lock it so that the cam is correctly timed. I pulled off the tensioner/idler/belt/camshaft pulley/camshaft sensor and finally the water pump after draining the coolant.

Re: Project: Double Ugly

Looks as though the tensioner pulley pinch bolt had slackened itself off. Or wasn't tightened to torque in the first place.

At least you've now rescued it from that perilous state.

Has your new water pump got a plastic or a brass impeller?

Neither, it's metal but grey and cast - assume aluminium, it's made by FAI.

The one I took off is the Fiat original and plastic. To be honest it looked good but the O ring will never go back in the slot as it's expanded.

The rest of the timing kit is supposedly genuine FIAT service parts though the manufacturers are different to the ones I took off.

Re: Project: Double Ugly

New water pump seal needed a bit of lube to go in. This was to hand:

Refitted WP, cam sensor, cam sprocket, auto tensioner and belt. Timing marks still good so pushed the tensioner rearwards to the max tension setting. 2 revs of engine and rechecked the timing. Then reset the tension to the centre of the hole and torqued it to spec.

2 more revs to double check everything.

Booty fluff. Just got to put everything else back on.

Note the file names of the pics, I'm tired!

Re: Project: Double Ugly

Most of the way buttoned up now. Not quite enough new coolant to run it for any length of time but it started up first time and sounded good.

Re: Project: Double Ugly

Managed to finish it off (bar the coolant). Also swapped the sump plug for a flush type mk2 one in the hope that it'll still clear speed bumps.

Will top up the fluids over the weekend and swap the insurance back over Sunday.

That means the Alfa's for sale! 300 if anyone's interested?

Re: Project: Double Ugly

"according to The Highways (Road Humps) Regulations 1999. The height of speed humps must also be a minimum of 25mm but no more than 100mm at the highest point."

Height of baked beans can:
110mm

Hmmm...

Re: Project: Double Ugly

Am impressed with your dedication and patience! Road ground clearance matters most away from the wheel axles, unless you straddle those narrow bumps down the middle ..
