Removal and replacement of timing chain

I'll shoot another coat or two on it and see what happens. Im going to have to start painting in the house............Yes! :laugh: Seems fine though, the color that is. Not much left till she purrs! :Brow: :3gears:

 

Lookin' great Rob! Nice work! :TU: :bglasses:

 

Yup, DH1608. If I paint it would be the pump, not the cover.

Thanks Cody.

 

Anyone know how to take off the crankshaft gear? o No:

 

Believe it or not they usually they just slide off, mine did both times I took it off.

Cool, thanks Dave.

 

Did a few little things today. Got the old crank gear off, removed old valve cover gaskets, cleaned all dirt/grime/gaskets off the front of the block, painted intake manifold bolts, ordered new pcv valve, egr valve, TSC solenoid etc, cleaned out heads as best as I could. Tomorrow I plan on puttin the chain and gears on, setting the crank and cam so the timing marks are aligned, put on the timing cover and button it up. From there its just fluids, hoses, tune-up parts, detailing and a rebuilt carb.

 

Ordered a new EGR valve ($44), PCV Valve ($3), TCS solenoid ($30), and some supplies. Found out I can't use the neoprene front seal from TA and will go with the stock rope seal. The entire gasket set for the timing cover is wrong so I had them order one for a Buick 455 instead of the Pontiac or Oldsmobile they gave me. Second time the gave me the wrong 455 gaskets. Lets see, 1 day wasted and i have the same amount of f***ing time as if i actually went to school! :af: :af: :af: :blast: :blast: :blast:

 

Because I either have to machine my timing cover or risk cracking the aluminum. It would be nice if I had know about this in advance, the directions stated no machining and the seal is much bigger than the opening. :spank:

Went BACK to the parts store and got the right timing cover gasket set for buick 400, 430, 455. When installing a rope seal should I soak it in oil first before fitting it? o No: Thanks :TU:

 

Brought the number 1 cylinder up to TDC. Put the timing cover and harmonic balancer on to adjust perfectly to 0 degrees. Got it at 0, removed timing cover and balancer. Removed cam gear and chain, lined up cam gear with crank then put cam gear and chain back on, loctite both bolts and torqued to 22 ft. lbs. Test fitted the timing cover, and gaskets. Trimmed gaskets. Put gaskets down, put on timing cover and started with the longest bolts to the shortest. The 4 shortest bolts in the oil pan and very bottom of front cover got me confused so I put them in and will pick up next week. Did not torque timing cover bolts yet. It went ok, the only problem is the bolts (brand new ARP) got really tight to put in towards the end and I felt like they were going to snap. The timing cover has a chip in one of the water pump bolts. Right now im very displeased with how the whole thing went. Bad day.

 

Im gone this entire weekend which kinda stinks but hopefully next week will go better.

Water pump buttoned up.


Timing marks aligned


Chain and gears on


Cover on

 

Did anyone mention cleaning out the bolt holes with a tap, I always chase all bolt holes with a tap before reassembly, flat bottom taps for blind holes. Also are the ARP bolts the same length as the stock bolts? Did I miss something, why did you buy ARP bolts any???

Dave Berry

 

No mention of a tap. I bought arp bolts through TA performance because nearly all the old ones had no threads left, they were rusted.

 

I was told no sealer and no rtv was needed.
