What do rocker arm stud girdles do?
A stud girdle clamps onto your engine’s rocker studs, essentially locking your rockers together to deliver the stability you need in a high-rpm performance engine.
What is a rocker girdle?
A Rocker Arm Stud Girdle (aka valvetrain stabilizer) is a bar that links all the studs together. It clamps over the polylocks on Stud Mount Rocker Arms.
How do you measure for rocker arm studs?
This is especially true when “long” pushrods and valves are employed – you should raise the “installed height” of the rocker arm to compensate for the longer-than-stock components….7/16 Rocker Arm Stud Kit.
| Installed Height | 1.750˝ |
|---|---|
| Adjuster Diameter-Pitch | 7/16-20 |
| Screw-in Depth | 0.800˝ |
| Screw-in Diameter-Pitch | 7/16-14 |
Do you use Loctite on rocker arm studs?
Red loctite is only for those items that you dont ever plan to remove. Rocker arms and any other engine parts dont fit that bill. cam gear bolts would be the exception. You just need something to seal the intake threads, as they lead to the port, and can cause a vacuum leak.
What is a main CAP girdle?
The main bearing girdles are used to tie the main bearing caps and bulkheads together, thereby stiffening the block lower-end and increasing crankshaft support.
How do you check pushrod geometry?
Set up a rocker and pushrod assembly and rotated the engine through at least two full valve lift cycles. If the pushrod is too short, the mark will be toward the intake (inboard) side of the valve tip. If the pushrod is too long, the travel will be toward the outboard or exhaust side of the valve tip.
How do you determine pushrod length?
Place the ball in the cup and measure the overall length including the ball. Then subtract half the ball diameter (0.1562-inch) to get the overall length. As an example, if the pushrod measures 7.6562 0.1562 = 7.500 inches.
What is the purpose of a engine girdle?
A main bearing girdle provides stiffening to your engine block. Since high forces act on the entire engine, especially in tuned engines, the use of girdle plates is advisable. They prevent the crankshaft from bending too much and withstand even high torques.
What happens if pushrods are too long?
Excessive pushrod length can then eliminate the ability of the cylinder to build compression. Naturally, this can cause anything from poor performance to, in severe cases, the engine not to start or even run.
How do I know if your pushrods are too short?
If the pushrod is too short, the mark will be toward the intake (inboard) side of the valve tip. If the pushrod is too long, the travel will be toward the outboard or exhaust side of the valve tip. An ideal pushrod length will minimize the travel across the center of the valve tip.
In which direction is the stud extractor turned?
The extractor nut has left-hand threads so turning the nut to the right (clockwise) opens up the jaws, and turning the nut to the left (counter-clockwise) closes the jaws. Then slide the extractor over the broken stud, and then tighten the nut by hand, and then using the 2 adjustable wrenches tighten the nut securely.
How does a stud installation and removal tool work?
The stud removal tools include a pair of body members which are each mounted on the stud to be removed and tightened against one another so that one of the body members may be rotated to effect removal of a stud.
