2 wrench valve lifters
What keeps 2 wrench valve lifters from backing off. I can see that with a lock nut they are more apt to stay in adjustment.

Re: 2 wrench valve lifters
Dennis,
"What keeps 2 wrench valve lifters from backing off?"
To answer your question: Not much.
Have had a few friends with those, and the adjustments backed off. Yes, there is a locking method, but in what I've seen, it's not as guaranteed as the lock nut. I've never seen one of the screws as pictured above. I have seen a style that uses a locking type thread form, (the trade name for it escapes right now).

Re: 2 wrench valve lifters
Could it be "Root interference lock thread", as used on the Mopar "leaning tower of power"?

Re: 2 wrench valve lifters
The lifter bolt shown in the picture, the slot will close up, or one side will brake off, NO FIX.
The best are BOBs, In IL.
They are made the way they should be. The bolts, nuts, and lifter body, laugh at a file.
As always, any brand of lifter, should be butt. None are perfect.
That is why some people say adjustable lifters loosen up, because the high spots wear off, and then they are loose.
Here are some pictures.

Re: 2 wrench valve lifters
One more thing, you do NOT need 3 Wrenches, on lifters, with a lock nut.

Re: 2 wrench valve lifters
Correct. And, you do NOT need to cut down your tappet guides in the engine block in order to adjust your tappets.Kohnke Rebabbitting wrote: ↑Sun Nov 03, 2019 3:49 pmOne more thing, you do NOT need 3 Wrenches, on lifters, with a lock nut.

Re: 2 wrench valve lifters
Ok so how do you keep the lifter from turning when you snug down the lock nut without using 3 wrenches? I have yet to see lifters that when down you could hold it with a wrench, maybe the flats were just peeking over the top. No you don't have to trim the lifter bosses, even if you know the secret to the threads per inch thing you still have to go thru several cycles to set them. But just taking a little off the top clears the way for adjusting without cranking the motor over to drop, check, turn again, adjust, drop to check etc.
I know the voices aren't real but damn they have some good ideas!

1. Butt both ends.
2. The lifters are Bob's, the only good ones. Take all the bolts out, and nuts off, and either blast, or wire brush the threads. Make sure the nuts do not move the bolt when installed, that is, rotating freely, and assemble bolts.
3. Put a heavy grease on the lifter body, none on the lifter foot, and install the lifters.
4. We set the valves, with out the valve springs.
5. We use a light spring under the valve to keep it out of the way. It came in a hand lapper, one time.
6. Push the valve down, take the other hand and take a reading with the feeler gauge, and let the valve spring, out of the way.
7. Grab the top of the bolt and place the wrench on the body of the lifter, and push lightly inward, with the other hand, loosen the lock nut, and you should be able to adjust the bolt, and nut by hand, and then snug, lock nut.
8. All the pictures I can find now are of valves on a Model A, which would be the same process as a T, and B Ford.
9. I always point the cam toes downward.

Re: 2 wrench valve lifters
So the lifters he sells are not the same as Snyder's ? They carry the 2 wrench lifters also.
