Investigation has identified likely sources of the seepage to be the sealant used on the CVT’s oil pump chain cover and the input shaft oil seal. The repair involves chain cover removal, a thorough cleaning and inspection of the sealing surfaces followed by re-sealing the cover and replacement of the input shaft oil seal with the new, redesigned type. PRODUCTION CHANGE INFORMATION: The available starting VINS for incorporation of the new input shaft oil seal are supplied to the right. This bulletin will be revised with the VINs for the remaining applicable models as they become available. Model Starting VIN Legacy L3002280 Outback L3100230 Ascent L3407153 PART INFORMATION: Description Part Number THREE BOND 1215 SOA868V9600 RING SEAL 31377AA510 OIL SEAL 806747030 SERVICE PROCEDURE / INFORMATION: As a first step, during inspection of the customer’s concern, confirm the fluid found to be seeping is CVT fluid (CVTF) and not engine oil. The photos below are examples of where CVTF seepage may be evident. Continued... CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS. Subaru Service Bulletins are intended for use by professional technicians ONLY. They are written to inform those technicians of conditions that may occur in some vehicles, or to provide information that could assist in the proper servicing of the vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do the job correctly and safely. If a condition is described, DO NOT assume that this Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Please recycle or dispose of automotive products in a manner that is friendly to our environment and in accordance with all local, state and federal laws and regulations. Page 1 of 6 • Once the inspection has confirmed the seepage is CVTF, remove the CVT assembly following the procedure outlined in the applicable Service Manual. • CAREFULLY remove the torque converter from the CVT and inspect the area of the oil pump chain cover as indicated in the photo below for any accumulation of CVTF and road dirt which may also have collected in the area. NOTE: A small amount of fresh CVT fluid may appear near the 6:00 position of the seal area during removal of the torque converter (GREEN circle). Seepage Point Fluid “Flows” to Low Point Seepage Out to Converter Case Continued... Bulletin Number: 16-103-16R; Revised 09/26/19 Page 2 of 6 • Remove the 7- (TR690) or 10- (TR580) 12mm hex bolts securing the oil pump chain cover. TR690 • TR580 Using a prying tool, CAREFULLY pry (GREEN arrows) the cover loose from the housing. Pry ONLY on the specific areas or “tabs” of the pump cover indicated by the BLUE arrows. When the cover starts to come loose, continue to pry ONLY on the tabs and not the machined sealing surface of the cover. Prying Tool TR580 TR690 Prying Tool • CAREFULLY remove all residual sealant completely from the cover and mating surface of the housing. DO NOT use any abrasive or gasket removal / cleaning discs. Use the adhesive side of a piece of duct tape (or equivalent) to pick up any loose pieces of sealant material which may be found in the cavity around the stator support. DO NOT use compressed air. Continued... Bulletin Number: 16-103-16R; Revised 09/26/19 Page 3 of 6 • Take note of how the sealant on the removed cover forms an additional “seal” when it becomes displaced into the chamfer around the inside edge of the case’s machined surface at assembly. • Inspect both of the machined sealing surfaces closely for irregularities. If necessary, replace the cover following the applicable Service Manual procedures. NOTE: Should the cover need to be replaced, always confirm the new part has the new-style input shaft seal with the additional side lip as described below before installation. • IMPORTANT: Before reassembly, always replace the ONE TIME USE plastic sealing ring on the center support and thoroughly lubricate it with CVT fluid. • The re-designed input shaft oil seal has a new side lip added to supplement the existing main seal lip. The purpose of the additional side lip is to direct the flow of dust and water around the seal and away from the sealing surfaces. Apply CVT fluid to the main seal lip only before installation. When installing this new seal, it is STRONGLY recommended to use the proper installer tool **OPTIONAL Special Tool 927890000 as shown in the illustration below. Otherwise, If the seal were to be installed too deep into the bore of the chain cover (beyond flush with the chain cover edge as shown below), the oil passage may become restricted or blocked. • • Oil Seal is installed flush with edge of chain cover and oil passage is clear. Continued... Bulletin Number: 16-103-16R; Revised 09/26/19 Page 4 of 6 • Once both surfaces and the area surrounding the cover are completely clean, dry and the new input seal is properly installed, CAREFULLY apply the new sealant bead to the cover along the edge of the chamfer as shown below. DO NOT apply sealer around the arrowed hole. DO NOT apply sealer around the arrowed hole. TR580 TR690 NOTE: As shown above, a properly applied, small bead of sealant will fill in the chamfered portion after the cover is installed. Do not use an excessive amount of sealant. • On the TR690, there are 2 different length bolts for the pump cover. Make sure the proper length bolts (A and B) are in their respective holes as shown below. Torque to 24 Nm (17.7 ft. lbs) in a crossing pattern. Continued... Bulletin Number: 16-103-16R; Revised 09/26/19 Page 5 of 6 • For the TR580 (all 10 cover bolts are the same length), apply the sealer, (EXCEPT for the arrowed hole), reinstall the cover and torque the bolts to 21 Nm (15.5 ft. lbs.) in a crossing pattern. • CAREFULLY reinstall the torque converter and the CVT assembly in reverse order of removal following the service procedure in the applicable Service Manual. • Road test to confirm the repair and proper vehicle operation.
