installing front crankshaft seal but seal pops out when it bottoms out.
Hello and welcome to Just Answer! I would be more than happy to assist you today. What is the part number of the seal you are trying to install?
ok do you have a engine serial number. I show a different part number i just want to verify
this seal i also tried(NNN) NNN-NNNN my serial #625443 when i press the seal in the lip curls under and pops in the middle. I can see the seal coming out from the sides along the crankshaft after it seats.
Ok, Please verify the ESN it should be 8 digits and located on the data tag. The info you gave me is NOT for an N14 but a 1968 NHC 250. if that is correct let me know. see below
the full serial # XXXXX XXXXX
That is the VIN# XXXXX need the Serial number from the engine data Tag located on the gear housing by the air compressor, It is an 8 digit number should start with 119 or 120
Ok thank you(NNN) NNN-NNNNis the correct part number ONLY if you don't have a wear sleeve on the nose of the crank. Once you mess up the seal it cannot be reused,Are you using the plastic seal lip holder while install? You must. There is no trick but to follow the procedure . A normal seal is smaller... A seal that can accept a wear sleeve is larger , can you see a lip on the nose of the crank?If so there is a wear sleeve and you will need to get the correct seal.
oil seals for service replacement have an assembly tool which protects the seal lip during shipment and installation. The "LDL TFE" oil seal must be installed with the lip of the seal and the crankshaft clean and dry. Do not use any lubricant. The use of lubricant will result in oil leakage at the seal.
