OPG question

[uniquesnd]

So I just installed OPG’s yesterday and when reassembling the housing I just fingertightened all of the torx screws and then using a criss cross pattern snugged them as tight as I could with a 1/4” ratchet. I was watching a few videos tonight preparing to reinstall the chains and I noticed a couple of videos where they went to 89 in. Lb on these? My original research showed there is no torque specs for these screws. Did I mess up and should I pull the pickup tube back off (really don’t want to as it’s a pain to get the screws in) or will I be fine with how it’s done? The gear spun freely as I had to index it to slide it on the crank.

89 in-lbs is not very tight. If the gear spun ok then I'm sure you are fine. It only takes a few minutes to pull the pickup off and redo it properly and then you won't have to doubt yourself.

When I did mine I actually torqued the screws and I remember thinking it was a joke.

That is one reason I snugged them tight as they were really difficult to break loose.

Ford doesn't publish a torque spec for those bolts as the pump is only serviced as an assembly, so 89 inch pounds was likely someone's best guess. If you didn't break any screws or strip any threads, you will be fine. You would be shocked at how many techs rarely torque anything with a torque wrench

I don't know where you guys are getting your information.

For the GT350 (which I'm sure is either identical to the Coyote or VERY similar) the sequence is

89 in-lbs on the left (passenger) bolt,
18 ft-lbs on the bolt with the rotating lug
89 in-lbs on the next bolt to the right (driver's)
177 in-lbs on the far right bolt with the other rotating lug.

Then, in the same order as before, an additional 45 degrees, 75 degrees, 45 degrees and 60 degrees respectively.

Oy-vey. Yeah, nope. That is a fail. I would follow post #5.

I would imagine you could warp things being meat-fisted like that. Bad juju for an OPG.

 

[CJJon]

...and those are torque to yield bolts, so you need new bolts.

 

[thelostotter]

OP is talking about the torx screws holding the oil pump together, not the four bolts holding the pump to the block.

 

[uniquesnd]

Yes I am talking about the Torx screws that hold the back plate on. When it comes to the bolts holding the pump to the block I torqued those per sequence but I feel as though it’s wrong so may redo them. I was not aware they are tty bolts as everyone is always just reusing them?

 

[uniquesnd]

So on the Torque to yield bolt thing. I called the local dealership and spoke to service and parts, both said to just reuse the existing bolts and could not give me a part number to replace them.

Torque to yield bolts can be reused 3-4 times

Can be..sure, Should they be -- NO.

Wouldn't want to wager my motor to find out....

Whelp, they have been properly torqued once and then meat-fisted tight a second time. Would you trust them being torqued to yield a 3d time?

Your not wager anything. These bolts are not under any stress they just hold minimum pressure. Hardware store bolts can hold this

I would have no doubt
