STOP INVERTED RAKE LINKAGE

If ball and pin transfer is slow, it can cause problems elsewhere within the pinsetter. Aside from the customers having to wait on slow machine cycles or ball returns, it can cause some expensive and un-needed repairs. One of the most common issues that can arise from poor elevator transfer is the Rake Trip Linkage becoming inverted (See photos below). This most commonly happens when the Pit Cushion tries to lower and is obstructed by a ball still on the Pit Board. Bowlers with high ball speed shooting at corner pins cause this as well. This will commonly not allow the machine to detect standing pins. It can also cause excessive deadwood, break the Trip Arm Assembly (12-252354-002) or the Hook Selector Bearing (11-436000-000) within the Detector. Although these parts aren’t terribly expensive, it is an unnecessary cost.
    
CORRECT LINKAGE POSITION      INVERTED LINKAGE POSITION

Even if the Elevator is in good working order it is still possible for the Rake Linkage to become inverted.

This month we will show you how you can keep this from happening. It will only take a couple of minutes and less than 1 dollar PER LANE!

Supplies needed

• 1 each- 2 inch shelf bracket
• 1 each- ¼-20 x ¾” bolt (11-002002-001)
• 1 each- ¼-20 nylock nut (11-170007-001)
• 1 each- ¼ SAE flat washer (11-190010-001)

Using the bolt, washer, and nut attach the shelf bracket to the existing hole in the C-Lever portion of the Rake Lift Arm Assembly (See photo below).  This will prevent the Rake Trip Linkage from inverting and causing expensive and time consuming repairs
