Broken harland sharp adjuster?

[nm9stheham]

Mmmmm.... actually the pushrod pressure would only reduce the tensile load of the adjuster nut.....if it ever moved the adjuster in the rocker body, which is doubtful. So the P-rod load really doesn't change things. The driver slot vs allen 'socket' is the obvious reason. If 'twer, I just get some new adjusters.

A set of adjusters from harland sharp will set me back around $180. For that much i will just swap out for the comp pro magnums that i have sitting around.

I know you're going to fix the adjuster problem, that's not even an issue. I know comp adjuster they're only like $49 or less. butt still the only thing I've heard you say was in here first post was I hope it went to the bottom of the pan and all along my only concern is that you get it out of there. (The broken off piece that is)
After fishing everything (the dipstick in my case) out of the pan with a magnet on the end of it Antenna, I then decided to take the oil pan off with the motor still in the car and for anybody who hasn't done that believe me when you get to You'll wish you had not. Just to find out I had already got everything out of the pan and had to take the intake manifold off and find the other two last little pieces laying up in the lifter Valley oh joy what a day or should I say few days

Wow...I'd find another brand of adjuster that fit or do like you said!

If the force was from the pushrod, the ball end would have sheared at the body. The nut was torqued and streched, unloaded, retorqued and stretched, and the fastener was never properly treated. Least that's my guess using the Crane adjuster issues from some years ago as the guide. The top pulled off at the thinnest area, probably at the stress riser where the drilled hole was formed into the hex, from repeated application of the max value or perhaps more on the locknut nut. I.E. - overtorqued... With the added weakening of improper manufacture.
Repalce them and you should be fine. If it was me I'd use the HS adjusters. The same thread count my not have the exact same pitch and I'd want them to be "right".

WOW, that adjuster looks short for a 273 rocker arm. Most competitive stuff has moved away from aluminum rockers for many reasons. Bulk is one of them.

Again, that adjuster looks SHORT.

I'd call Smith brothers and see what their adjusters cost. Think about this for a bit and see if it starts to get clear, and I'm not trying to be an ***, I just want to grease the wheels about mass production parts.

For the same reason that Chrysler used a relatively short installed height on their valve springs is the same reason why manufacturers use the shortest fastener possible....it costs less.

In the case of valve springs, you need 16 per engine, times the number of units and you can see the cost savings when you consider the total number of small blocks built was in the millions. In a smaller way the same thing happens with other products.

That adjuster is too damn short.

Unless pictures make things look shorter!!!!

Good work; was it in the valley?

only a few threads are above the lock nut so yea, they could be longer. I will see what options there are out there. The ones harland sharp have are only 50 thou longer.

yes it was, stuck in a drain hole!
