Cam bearing help

[73GreenMachine]

I've been struggling away for the last 7 weeks on one problem: finding the correct cam bearings for my block. I have been to my parts shop no less than 4 times to pick up different sets of cam bearings, all of them the wrong size. I know I'm complaining a bit, but still I could have had the engine in the car by now if I had it sorted out. It's the one thing holding up the rebuild. I have tried 3 ACL sets and a Federal Mogul set.

Federal Mogul Bearings too small
ACL 4C5826 4th bearing too big
ACL 4C5829 4th bearing too big
Custom ACL set 4th bearing only had 1 oil hole instead of two


The custom set I waited like 4 weeks for them to be made to order.
I have a 200ci pre crossflow block in a Ford TC Cortina. The car was manufactured in July 1973 and I think the block was made in 1972. I'm in South Australia. I can't get casting numbers right now because my block is at the machine shop. If they are of any help, I'll get them. The bearings in there were Ford item (I'm imagining theyre stock sizing).

Any help would be real useful right now because I can't wait to get the Cortina running again with the mods so I can feel the POWER
If someone knows the right bearing number, or can point me in the right direction(like a company to get them from), it'd help heaps. Thanks.

Measure the originals. Compare to ACL specs per their PDF.

It's PRE-Crossflow, right? They've sold you two versions of CROSSFLOW bearings.

They list 4C5829 as Sept '75-Jun '76 4.1 iron head crossflow, two oil holes in last bearing.

4C5826 is listed as 4.1 alloy head crossflow Sept '80 - Dec '85, Sept '84-Jan '92 4.1 alloy head crossflow unleaded, Jun '80 - Dec '90 3.3 alloy head crossflow leaded/unleaded, EFI variants of all the above.

I get 4C5768 for your engine, but 4C5766 has the same specs . First and last the same, middle two are identical to each orther but different to 1 and 4. There's also 4C5749 where all bearings are the same.

im picking the 4C5768 STD ,but they could be 4C5766 STD or 4C5749 STD.Do you know if all 4 bearings are the same size? if so they should all be 45.961mm/45.987 shaft size and a 49.098/49.124 housing use #4C5749 STD. If the 1 & 4 journal are 45.961mm/45.987 on the shaft and a housing size of 49.479mm/49.505mm and the 2 & 3 journal are 45.961/45.987mm and a housing size of 49.098mm/49.124mm , use 4C5768 STD .The 4C5768 STD have identical sizing to the 4C5766 STD set and i cant find the diff between the sets as i have never had the 4c5766 set ,but i think its probably a oil hole .
Hope this has helped and not confused you more .Let me know if you need any more info.

According to "ackle" the 4C5766/68 sets have exactly the same subset part numbers... Weird.

Hey you guys are legends! Where do you pull this stuff from? Experience I guess. So they've been giving me crossflow bearings. Its funny because the guy rang up ACL and they said 4C5826 were the right size. The thing that stuck out the most was the missing oil hole.

Bearings 1 and 4 are bigger than 2 and 3 if that helps and its a 200ci pre crossflow.
I think I'll get the 4C5768 set tomorrow and try them.
Thanks heaps . I'll let you know if they work or not. I made the mistake of giving the block to the machine shop, so I have to run between the two places to fix stuff. It'd be fun if I had the Cortina to do it in.

Just to let you know, the bearings went to the machine shop and they look like they will fit. ! and 4 both have 2 oil holes and 2 ands 3 are identical aswell. Again, thanks for the help.

Good. I wish you luck fitting the other, leftover bearings in an appropriate part of the idiot who prescribed them.
