Re: loose in the lifters
The new Tardel-Bishop book recommends clamping the bolt lengthwise in a vise, and giving it a squeeze to "shorten" that necked down area of the bolt a bit. But if the end of the bolt is sticking too far down into the body, you will get the problem you have.
I think those lifters must have been made for reground cams, with smaller lobes. I'd think it wouldn't hurt one bit to give the loose ones a super-cleaning before assembly and drop some Loctite into those threads after adjusting. |

Re: loose in the lifters
Since there are no loose ones after the squeeze I skipped the loctite. Like I mentioned before, if you were turning that 7/16" wrench down in there you would agree that at 5 ft lbs of torque, these just plain won't loosen in service. Also there was no loss of tension even when there was only a gap of 1/16" under the bolt's head. If these were not made from high quality materials I don't think they would have held up to the wrenching involved. Edit: The 7/16" bolt head had tricked me into thinking the threads were 1/4" fine, but they are bigger. Either 5/16 or 3/8"

Re: loose in the lifters
What would a set of early -1950s- Johnsons be worth? Just curious.

Re: loose in the lifters
How do I know the lifters I buy are original "Johnsons"?

Re: loose in the lifters
Are they old NOS potatoes or the crappy aftermarket ones from overseas? My dad used to ask me.... "What weighs more, a pound of feathers or a pound of lead?"

Re: loose in the lifters
5 ft-lb = 12in x 5 lb = 60 in-lb = 12 in x 5 x 16 oz = 960 in-oz, and so on...
GB, I'd like a further explanation of your meaning about compressing the bolts in a vise. Do you mean the end of the bolt against one jaw and the head against the other jaw, or do you mean the threaded part of the bolt squeezed between the two jaws. I think you mean the latter, since I can't see how you would compress the bolt lengthwise without damaging it. So are you then putting two flats of distorted threads on the bolt? Always enjoy your comments.

Re: loose in the lifters
J Witt.
The bolts are squashed lengthwise. It creates a pitch error between the lower and upper parts of the thread. The crush is controlled so when both the top and bottom threads are both engaged in the nut (the lifter being the nut) the desired resistance to turning is created. That's why when they are turned too far in, you lose the resistance as not enough of the lower thread is engaged. Mart. |

Re: loose in the lifters
What do you think of the running surface of this lifter, which is out of my '36 LB engine. Would this be reusable without resurfacing?
These have nice tight screws, I'd guess around 5 ft-lbs. John

Re: loose in the lifters
Agreed. Now I gotta go bust out my file. Good to see that in post #2 from binx, he was right in the zone with 60 inch lbs! Lots of good info from lots of knowledgeable folks, as always.
