Hi Dom, after torqueing down the cam pulley bolts and do the 2+2 revolutions, did you reinsert the cam locks to verify the timing was still correct? The act of torqueing down the pulley bolts will actually pull the pulley round a bit relative to the shaft and stretch the crap out of the belt, so when trying to reinsert the cam locks afterwards I've always found the exhaust cam to be a few degrees out, as the tension is redistributed around the belt afterwards.
Hello. Have you got a video where you are changing the solenoids on a 1750 engine?
@@mohapimoloi9457 I haven't swapped the solenoids, so unfortunately I don't, sorry.
Thanks for this video! Do you remember what size socket you needed for the cam shaft caps?
I believe it was a 30mm socket. It was bigger than what my SidChrome toolkit had, and one of the biggest in my SuperCheap Auto kit.
Thanks. I ended up getting a 30mm one from bunnings.
Well done for doing it yourself 👏
In theory it is easier than other cars - not so much when the tensioner is bolted in with more than twice the torque of the wheel bolts.
Hello there! Great work! Question: Where did you get the torque information for the screw tightening?
There was a guide on the Alfa Romeo forums that had torque settings for most engine bolts. So far I've done a couple thousand Km with no issue.
do you have any idea how to synchronise timing? Most likely due to worn variator, timing belt skipped a tooth or 2 and now i'am getting bunch of codes, are locking tools gonna be any help with that? and are there any markings on crankshaft or camshafts that indicate proper positions of cams?
The locking tools will keep them at the correct angle since they align the camshafts, not the gear wheels. Normally there aren't markings on the gears unless a mechanic has replaced the belt in the past without the locking tools. You could get the cams into the correct position by lining up the camshafts at the rear of the engine with the positions that the locking tools leave the cams, but they could end up 180 degrees out, and you also need to align the crankshaft. I'd recommend buying all the locking tools for your situation.
@@domsdriveway1282 its essential what i ended up doing, got the locking tools, camshafts where in correct position, but crankshaft wast out by 1 or 2 teeth, got the belt out set crank to correct position according to crankshaft locking tool and everything is working fine. Side note did you have to replace your vacuum pump seal after reassembling everything because mine started to leak oil after.
Also thanks for the vid it helped me a lot
You should consider changing the expansion tank
I variatori di fase come li hai rimessi apposto dopo che li hai svitati?
The camshafts stay in place with locking tools. The gears are timed using the belt at maximum tension, then locked to the camshafts with a very tight tension.
Is this 1750tbi good engine?
It is very good. 157kW and 200,000km on the odometer with only one issue: the crank sensor needed to be replaced.
@@domsdriveway1282 nice i want to buy used one with 174000km on it. but whoever I ask about the durability and reliability of the engine, no one knows anything to tell... before I had a MiTo 1.3 which was lightly tuned and served me for 5 years, so now I'm looking for an ideal replacement. Thank you
@@domsdriveway1282 And one more question do you have any advice does I need to look something special on qv (for example timings, turbo etc) i mean for some factory bad part.
Looks good boss
It's like Hiroshima - not that I'm in Japan...
