Windage tray torque

[Dan D.]

I am about to re-install the windage tray on my 327 after re-doing the oil pump. I had flats & split locks on the windage tray, but after reading some of the post here I decided not to go that route.

I bought a package of windage tray nuts aftermarket. They are plain nuts with captured external tooth star washers. Don't think you would want or need flat washers with the star washer nuts.

After reading the archives back to 2003, there is a lot about windage trays, but not fastening torque. It was recommended in one post to use interference thread nuts, but I don't know how one would torque them.

These are 3/8-16, so I would think 25ft lbs. would be okay. Sound good? Just wondering what some of you guys do.

Thanks, -Dan-

i would still use red loctite on the nuts.

I second the loctite & use stock nuts. I've seen them still tight after 30 years on a motor. Loctite is the key.

Yes, star lock washers would never be used in conjunction with slpit lock-washers; it's one or the other and neither are a very good thread locking device.

You could use stover-type lock nuts but why? As clem and Ken have mentioned just use stock nuts with Loctite.

On my 61 FI, if I remember correctly the windage tray is attached to extensions coming off the main caps and are secured with jam nuts. Loctite is not really needed but could be used for a pre-emptive measure.

Re: Windage tray torque

Okay, thanks guys. Joe, I don't know anyone dumb enough to combine split locks and star washers. My comment was about splits and flats, where the star will lock to the flat, but then both are free to rotate about the tray. Flats are not necessary here anyhow.

I will use 242 threadlocker with the aftermarket nuts. Red 271 Loctite can be very difficult to remove, and I don't think it is necessary in this application.

No one has commented on the 25ft lbs. torque, which was the original question. So I will go with that.

Re: Windage tray torque

using any type of lock washer inside a engine is looking for trouble because if they fail you will have pieces loose inside the engine. split lock washers are the worst because they can break into 2 pieces.

Re: Windage tray torque

Okay guys, here is the latest plan. I found several of these nuts in my nut & bolt collection. So the plan now is to use these along with Threadlocker 242. How does this sound?

On a similar note, the 1/4-20 screws that hold the oil filter bypass plate on. What would you use on those? Just Loctite? Forget what was on it originally. Thanks, -Dan-
