I posted this full size van forum but was told this my be a better place.

I'm finishing a 460 crate motor for my '80 E-350. I had ordered a new timing chain cover but it has some minor looking but major fitting differences. The bolt holes are larger and the crank access where the seal goes is different as well. When looking up the casting stamp on the original cover (D2VE-5069-AA) I get a a 1972 Lincoln??

The differences have to do with how the counter ballancer fits on after the cover, there is a lip on the old cover that the counter ballancer seems to be machined to fit where on the new one the lip is not there. The old cover fits on the new motor with the ballancer perfectly, on the new one the ballancer pushes on the seal like it wants to go in further.

In order to make the new cover work I will have to machine the end of the ballancer and sleeve the bolt holes. Lots of work for this part so I'm starting to search for the cover indicated by the stamping, 1972 lincoln.

If you look at the photo you will see the diameter of the seal opening is different but that is the front. The back of the old covers diameter is the same as the new cover. You just have that lip for the coutner ballancer to fit in.





Thanks,

What I can tell you is that a different seal for the newer cover is used. . .not the same seal for the old cover. The newer covers seal goes in from the outside. . .did you put the crank spacer/hatchet weight in along with the oil slinger? The balancer bears on that, not the cover. . .

It works, trust me. I used the cover from my 1987 460 on the Lincoln 460 I rebuilt for my 87 F250. External balance cover to internal balance motor. And yes, the bolt holes make for a rather soppy fit

try to center it up on the crank, with the seal installed so it sits evenly around the crank and bolt er down!

 

did you get that new cover from jegs?

 

I got mine from Autokrafters about 5 years ago when no one else was selling them. They show a tbird 429-460 cover with part number D2VZ-6019 for 68-76 tbirds for $119. Might be cheaper elsewhere.

 

By the spacer/hatchet I guess you are refering to the counterballancer, the smaller weigh that sits between the oil slinger and harmonic ballancer? What I'm seeing now because of the way the new seal is designed there are 2 lips instead of one. So my "hatchet" had surface rust behind that original seal. So now when I mock up the new case and seal the part of the "hatchet" that was rusty is now in contact with the new seal. I have cleaned it up as much as possible but there is still some pitting. I'm worried about leaking or the seal breaking down where it is rubbing on the slight pitting. I have acesss to an excelent fasteners distributor (ababba bolts in San Marcos,ca) so I plan to get some shoulder bolts to see if it helps with the alighnment.

I've got 3 of these covers now, one I bought off the guys that sell them on Ebay, one for Kragen and one from napa. They are all different in some way!!??

BIG thanks for your info!

Cake,

They make repair sleeves for these things to cover the worn shaft of the balancer.
They're under $20 with the seal.
Timken and Fel-Pro each have a different style.
I like the Timken.
Use stud and bearing mount.

 

After talking with some mechanic friends and all the info from you guys I'm not feeling good about the condition of my counterbalancer, they are recommending I replace the balance or go with the sleeve option. Since the parts are cheap I'm going to do both. The motor has been balanced so I'll need to drill and weigh the new balancer if needed.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

I'm over the hump with this issue but just realized I gave my water pump cover plate with my core =[ So I'm waiting for a gang of parts including another water pump to get back on track. The water pump is a wash, I decided to upgrade it anyway.<o></o>

Thanks again everyone.

Maybe some one else sells them now but I had to buy my water pump cover from Ford. They didn't come with the new water pump. The small block ones usually do. The ford part number is C8SZ-8508-A and it was $22 in 05.

 

I took the one back I bought locally and ordered a hi-pro one online that included the plate. All good =]

 

Thanks Dirt racer!

I know that P/N is going to save my butt sometime!

I'm seeing those covers on ebay now but they want 30-40$ for them
