PART(S) INFORMATION:
FRONT TIMING CHAIN COVER RESEAL
1. Clean sealing surface on timing chain cover, crankcase, cylinder block and cylinder heads. Remove oil, old sealant, and dust from sealing surface.
2. Apply sealant "A": Suzuki Bond 1207F (# 99000-31250) to timing chain cover sealing surface area as shown in the figure. Ensure proper sealant bead. Do not over apply.
3. Apply sealant "B": Suzuki Bond 1207B (# 99104-31140) to the mating surfaces of the cylinder heads and cylinder block as shown. Use a plastic scraper as a jig to force the sealer into the air gap formed by the cylinder head, block and head gasket as shown in call-out "A" below. There are four areas "B" where this must be performed.
NOTE:
Failure to perform this step will result in oil weepage/seepage that will migrate down the front side of the engine block. This may appear and be misdiagnosed as a crankshaft oil seal leak.
