E-57H on an EZ Mount Classic Lift Frame Page - 2

We replaced the King Bolt. Look at the wear. It is almost as if Meyer doesn't care about wear. ALL of the ORIGINAL bolts on these plows have an incorrect shoulder length. The wear occurs on the threads instead of the shoulder. It wears on the shoulder too, but it begins to wear immediately on any threads first. We replace all bolts with longer ones, using washers if we have to, so that we can ensure the proper shoulder length. To get the old bolt out, we had to use a 24" breaker bar. This is because the bolt was inserted from the top down, instead of the bottom up. After we got the nut off we found the threads in the nut were actually smeared. Because......

When the plow tripped, the King Bolt nut was rubbing on the Base Angle of the blade. According to the plow owner, it was the original bolt. They never changed it. So it was assembled wrong from day one.

On the face of the Moldboard were two tears. They look like cracks, but they are in fact tears, where the weld on the back side is tearing out of the face of the moldboard. This is caused by excessive tripping, and also because there are only two welds holding the angle iron brace to the moldboard. This brace does double duty as the trip return stop. The ST Series plows have flat stock welded to the Sector to act as stops. For some dumb reason Meyer left them off the C Series plows. They should have used a section of C Channel instead of angle.

Closer look at the tear.

Here is a look at the back side. You can see where the paint seeped through the tear. It was not the weld that cracked, but the moldboard sheet that tore.

Here is the Lift Arm. Like the King Bolt, again the shoulder is too short, so the threads began to wear immediately. The shoulder also wore from the constant up and down of the plow.

We welded in a steel Bushing.

We also used a longer bolt when we mounted it on the truck, with a longer shoulder. We had to use a washer on each side, but now it will not need to be replaced again anytime soon.

You can buy an arm with the bushing welded in and a grease fitting in our eBay Store.
