To me the wear doesnt look that bad. If it was me id keep the old cover. It will likey work fine. The water pump fan should do fine as long as it hasnt gouged holes to the other side. I am no expert but have changed my water pump for a new one and rebuilt oil pump while i had the timing cover off on my 67 430 V8. If it was my car I wouldnt replace it. If it didnt cool the engine then Id just take the water pump off and then order a new cover. But if you dont mind spending the extra then go with a new cover.
personally,,, I would think that it would be a lot cheaper to tig weld any thing that needs repair on that cover than to buy a new one.... when you order your new chain and gears get the all steel gears or the roller chain gears... dont use the factory plastic covered junk ......
Use only roller chain like TA sells. My first timing set lasted no more than 1500 miles to get slack like yours. Even new it had saome free play. Now the roller chain is stiff like solid bar. Don't waste manoy on cheap junk. As they say you got what you pay for.
That's exactly what I was thinking.... because this car is so original I really dont want want to be replacing any of parts unless I really have to.. I got the timing cover back this morning from my welder and he done a very tidy job fixing it. I've given it a quick cover of primer before I paint it and tap a new hole for the bolt. Perfect - roller chain it is so! Thanks for your help guys!! :TU:
I'vr cleaned up the balancer today - lots of old oil sitting on it from where the old seal was leaking. The balancer looks good to be, but then again I'm no expert! Just remembered, must check for any ridges on the balancer from the seal....
ONE LAST THING! The cam gear is straight forward, line the dot towards the crankshaft straight down. The Crankshaft gear has a dimple on it also, align the two dimples from the cam and crank. I have seen MANY guys cannot find the dimple on the crankshaft gear (its on backwards) so they turn the crankshaft to align the cam dimple to the key way on the crankshaft therefore making the cam to crank teeth off by 3. The last Buick I bought, the first guy had a broken chain. He replaced it. It would run on only 4 cyl. So he sold the car. Next guy replaced the heads with freshened ones ($700) STILL ran only on 4 cylinders. So he sold the car. Next guy replaced the cam/lifters and STILL put the crank gear in backwards! (took it apart and put it back together as he found it) Again, only ran on 4 cylinders, SO he sold the car. I bought it, sat and thought about it for 20 minutes... smiled, took off the timing cover and TA DA..... If you do something, and it runs worse then you did something wrong. After the first guys errors, I knew where to start. So after these guys put $1800 into the motor, and I bought the car for $1200, made a timing cover gasket as well as the crossover gaskets... I sold the car for over $5000!
I'm glad you used the original cover. It looks great. I painted mine too but I didnt use any primer. I used the Duplicolor paint for engines and it works just fine. Either way looks great. I learned the hard way that replacing parts that dont need to be replaced is a waste of time and money.
That chunk broke out of the front of the hub aint good..... I would replace that puppy if I had another one.... On a street car, I doubt that the missing piece would affect the balance that much....
I agree with DOC on that chunk aint good........an I aint no expert, but.........I 'tink grinding off the rest of that lip where the chunk is missing will minimize the impact of da chunk being gone. Or even die grinding a similar size/shape piece on the opposing side would cancel it out at least. :bglasses: Your call though!
