Rake timing

[yazu]

JBEES or someone please post link for fixing rake problems. Thanks. Rake caught side board and when it went back out, it also took out pin light. Got a break though, bulb did not shatter when it hit the deck. Yea. Never seen the rake board so high. It catches the deck when dropping. Crossing my fingers. Too old for this.

Steve Stafford has one posted in the referance section called "raking in the dough" BUT
I believe he has made some changes to that one. It will work but the newer version is
easier to do, I think. Give me an email and I will send you the copy ...

Follow this adjustment step by step. Don't cut any corners:

Step 1: Perform deck lift shaft adjustment. Adjustment 13 on page 3-16 in your service manual. This will position the deck lift shaft and the rake sweep shaft in the proper positions.

Step 2: At zero degrees, position "C" lever so that its closest point is 1/4" from rake sweep shaft. To adjust, cycle to 90 degrees and loosen set screw on rake trip shaft assy. (If you loose the gap at the trip latch, don't worry. Don't open trip latch until you get done with step 7) Remember that the shaft must be adjusted in 1 turn increments. Each rotation of the shaft is about 1/32” change in gap.

Step 3: At 45 degrees, raise out-of-range latch. Set rake sweep hook clearance above block to 5/16" by adjusting the link between the collar for the curved shoe and the rake hook sweep cam follower. (You should have changed 12-250040 link and roll pins if there was too much wear) This adjustment may cause you to have to adjust the out-of-range latch.

Step 4: While still at 45 degrees, lower out-of-range latch. Pull the out-of-range reset lever at the rear of the pinsetter and while holding it in its rearmost position, rotate the middle cross brace until the short inner arm on the out-of-range blocking latch just drops over the pin in the cross brace. (The reset lever can be held in its most rearward position by placing the palm of your hand on the connection of the adjusting link and the collar for the curved shoe and holding this down) Tighten the bolts. The cross brace may be rotated by placing a pin punch through one of the roll pins in the center cross brace.

Step 5: Position rake at rearmost position (180 degrees) and measure gap between rake sweep arms and cross member of frame. This gap should be 1/4" at the closest point of either arm. This gets the rake as far to the rear as possible without hitting the frame. Use the rake sweep link to obtain this clearance.

Step 6: While still at 180 degrees, loosen rake lowering stop bracket and allow it to fall away from rake lift shaft. Position rake lift cam follower in low of rake lift cam by rotating the gear box by hand and watching the rake lift shaft until it has reached its furthest clockwise position. Adjust the rake lowering stop bracket to obtain 1/16" between it and the lower side of the "V" lever. Be sure the bottom of the stop bracket is solid against the frame of the pinsetter.

Step 7: Loosen right hand rake stop and move it as far forward as possible. Position machine at 135 degrees and set clearance between rake sweep hook and block to 1/16"…or less if you like. Use your left hand rake stop bracket to obtain this clearance. Tighten left hand rake stop bracket. Using the right hand stop bracket, push the bracket and the rake support arm rearward until the left support arm just starts to lose contact with the left stop bracket. Both sides should feel the same when pushed toward the rear. Tighten right hand bracket.

Step 8: Loosen jam nut on shock absorber plunger and turn fixed stop counter-clockwise until rake trip latch WON'T latch. (You will have to trip it back to see if it won't latch.) When you reach that point where the trip latch won't latch, start turning the fixed stop clockwise until the latch just falls back into place. Turn fixed stop 1/2 turn more clockwise and lock jam nut into place. This will create a 1/32" gap (actually, slightly less) at the latch.

Step 9: Position rake board between the 2,3 and the 4,5,6 spots on the rearward sweeping motion of the rake. Measure and record the height of the rake board. Continue to cycle pinsetter until the rake board is 1" behind the #1 pin spot on the forward motion of the rake. Measure and record the rake board height. Release the rake sweep hook and allow the rake to come forward. This will release the pressure off of the rake lift cam. Take the two measurements and find the amount of the difference between them. Divide the difference in half. If your first measurement is higher than your second measurement, add the divided difference to the second measurement and record it. Record this number as your "desired height". Loosen the six bolts holding the rake lift cam in place on the 1:1. Rotate the cam clockwise ever so slightly and tighten the bolts. Move rake rearward and latch back onto block so rake board is again 1" behind the #1 deck spot. Check to see if your rake height is at the "desired height" you wrote down before. If not, continue adjusting cam until you obtain that height. If you did this properly, you should be able to return to the spot between the 2,3 and the 4,5,6 spots on the rearward motion of the rake and obtain the exact same measurement. (If your second measurement was larger than the first, reverse the procedure by subtracting the divided difference from the measurement to obtain the "desired height". Then rotate the cam counter-clockwise to get the desired height.)

Step 10: With rake at either position mentioned above (1 inch behind #1 deck spot on forward motion of rake or between the 2,3 and the 4,5,6 spots on the rearward motion) set rake board height to 1/4 of an inch by adjusting the rake lift rod from "V" lever to sweep arm. This clearance can be set to your preference, but I have found that 1/4 of an inch is a reliable height.


By following these adjustments step by step, not skipping ANY of them, your rake will sweep near perfect. If you skip any adjustment or do them out of order, you will not obtain the desired effect. In other words...you’re on your own. If you have any questions, feel free to call me...480-620-6758

Well like we thought on the phone JBEES she was indeed 180 Deg. off. Thanks much for the help. When I got her back in time, we had a roller coaster in the sweep pattern. Took a few trys and this and that adj. and she is better than before. Had a few bends in small rake lift rods. Only thing did not get done was pin light. May let elec. (Smit-smut) have that honor. Thanks to all for the help. Been to Albaqr. but never Mesa. Some day maybe.
