The plastic shoe for the TA typecomes as part of the main unit and no assembly is required.One flat washer should be installed on each side of the idlersprocket. However, the CT-TCS80 and CT-ETS80 should have twowashers installed on each side. The idler sprocket attachment boltand flat washers are included with the idler sprocket.LL1T2 L2Note: Only the CT-TCS80 has two washers installed on each side.Plunge ApproximateS H H1 F G B N T1 T2 E Z DP DO O L L1 L2 Force MasskN{kf} k /unitS H H1 F G B N T1 E W R T2ET1T2ET1TCS TypeDPDOStampFlat washersRAttachment boltZ: teethO : boltsize30 129 74 7 58 56.2 11 23 20 12.5 17 69.12 76 M10 42 29 6.5 0.10{10}0.25{25} 0.6030 129 74 7 58 56.2 11 23 20 12.5 15 76.35 84 M10 42 29 6.5 0.10{10}0.25{25} 0.6938 163 87 9 70 70.5 12.5 28 25 15 13 79.60 89 M12 52 36 8.5 0.15{15}0.39{40} 1.1538 163 87 9 70 70.5 12.5 28 25 15 11 90.16 102 M12 57 38.5 11 0.15{15}0.39{40} 1.37StampNBWNBFlat washersGFSGH1FHH1 SHETS TypePlungeForcekN{kf}Attachment boltFlat washersIdler sprocketIdler sprocketTensioner main bodyTensioner main bodyFig. 1 Chain tensioner assemblyApproximateMassk /unit30 143 74 7 58 56.2 11 23 12.5 140 120 20 0.10{10}0.25{25} 0.3938 164 87 9 70 70.5 12.5 28 15 140 140 22 0.15{15}0.39{40} 0.6538 164 87 9 70 70.5 12.5 28 15 140 140 22 0.15{15}0.39{40} 0.6544 187 104 9 86 82 14.5 33 17.5 140 160 25 0.29{30}0.59{60} 0.99125
AccessoriesHandling PrecautionsWhen installing the tensioner on a base after attaching the idler sprocket to the tensioner, be sure to fasten the idler sprocket and thetensioner with a bolt. The following table indicates the tightening torque. Be sure to use bolts with a strength classification of 8.8 or more.When setting the tensioner, adjust with a shim so that the center of the idler sprocket and chain are aligned.If the idler sprocket is anchored in place, check whether or not the sprocket can turn smoothly. If it does not turn smoothly, the bolt maybe too tight. Loosen the bolt and then retighten properly.

(Aslotted hole is convenient.)6) Push in on the chain with thetensioner and temporarilytighten the tensioner to thebase with a bolt. (Fig. 4)Then tighten the hexagonalscrew and anchor so that theswing angle is about 15.Fig. 2 Tensioner position (front)BaseShimRollerchainFig. 3 Tensioner position (side)BaseBolt10-10010-60ShimHexagonal screwFig. 4 Tightening the tensionerCT-ETS60,80 0.04{4.0} 0.04{4.0}CT-TA40 0.03{3.0}CT-TA50,60 0.04{4.0}CT-TA80 0.05{5.0}1) Push in on the roller chain with the tensioner’s idlersprocket (Fig. 5) and determine the position of the holeon the attachment base.2) Open a hole in the attachment base. In this case, two boltholes are required, but a hole that is as long as possible willmake positioning simpler, and the re-tensioning operationwill be easier when the chain elongates.3) Temporarily tighten thetensioner with two bolts. Atthis time, adjust with ashim, etc., so that thecenter of the idler sprocketand roller chain are aligned.(Fig. 6)Fig. 5 Tensioner position (front)BaseShimFig. 6 Tightening the tensioner4) Push in on the chain with the tensioner and, if the amount ofslack is appropriate (), tighten the nut and anchor the tensioner.Aim for a value less than = 0.02 x L.

If any of the following occurs, reset thetensioner.Contacts the side of the idler sprocket: Not centered properlyVertical or traverse vibration: Insufficient initial tensionIncreased noise: Excessive initial tension5) Perform a test operation and check whether the tensionerworks properly.
