Hi All, It looks like I have a slight front main seal leak on my 430 challenge. Can anyone tell me if this requires pulling out the engine for access? It looks like I might be able to get the front crank pulley off with a low-profile gear/pulley puller if I can find one. Does this require just removing the crank pulley for access, or do I have to remove the whole front engine cover? Anyone have any service manuals, instructional threads, or instructional videos on this? I haven't been able to find any yet. Also, assuming I can get the pulley off, replace the seal, etc....what is the torque for the crank pulley bolt? Great forum!....thanks for all the helpful folks on here!
