Hi 

I am in the process of stripping then re building a spare 1.0 Ecoboost engine with aftermarket rods and pistons but the one thing I need is some main bearing cap bolts does anyone know where I could get hold of some?

Having done much reading and googling I did find the torque settings for the main bearing bolts which I would share if anyone needs that information.

 

Thanks in advance Karl

Thought I would post a update on the main cap bolts. Ford dont sell the bolts because they would rather you buy a whole engine as thats better for the planet. My solution was to buy some head bolts from a Ford Transit and cut them down to size as that worked for me. I did try a few other bolts but they didnt have the correct flange on the head of the bolt.

Part number for the bolts 300590350 Elring Cylinder Head Bolt Set

 

The clearence on the mains is 0.050mm taken from a low miles engine that I am changing the rods and pistons out for upgraded items.

Hi, this is really helpful but I can't find the part you used. Could you possibly share a link? Also I have the bolts but I think they may not be good for a second use. Do you know if they are also torque to yield? I'd like to see the torque specs you found also if possible.

Thanks

Please remember the bolts will need cutting down to size which I did with an angle grinder. I did a bit at a time and cooled the bolts in water. Once they are cut to size you will want to clean them up with a sanding disk.

 

The bolts are a one use item as they stretch when you fully torque them up so if you used them a second time you would make them weaker. At the end of the day the bolts used by Ford are just 10.9 grade which is what is have found to replace the originals with. The important part is the flange made into the head of the bolt as this spreads the load out on to the main cap. When I was looking for a replacment none of the contenders had a nice big flange so I took to buy random bolts to test and measure then for suitability. 

 

Good luck with your project.
