Setting up a 164 12v V6 engine's cam timing and installing timing belt.
Had a few moments today to work on OLD NERO's engine. I put in a new used crank, new main and rod bearings last winter but never got much farther.
Today I set up cams on their timing marks. set crankshaft at top dead center (TDC). inspected good and bad (broken outer spring) mechanical tensioners, installed timing belt and set belt tension so I thought a little fresh show and tell might be in order.
I also used dial indicator and adapter in #1 cylinder on rear head closest to upper engine mount to show it but TDC mark on front crank pulley works just as good if you don't have dial indicator.
Also I show how to use Rick's pdf timing template so you don't have to pull off valve covers to see timing marks on cam bearing caps but thought I would show both way just for grins.
I hope this is helpful.
Pictures:
1- Broken outer spring tensioner see pointer way below reference mark.
2- Same broken tensioner pointer.
3- Good tensioner pointer will only go about 1/2" below reference mark before outer spring is tight.
4- Both good and bad tensioners.
5- Back of tensioner with broken outer thermal clutch spring.
I show tools I used, too. You can do the job without any special tools if you have needle nose pliers, sockets and Rick's template.
I will add this thread to my sticky on timing and water pump info.
Happy Alfa Trails to you!
