rear oil seal on 5718

[jtubbs]

hi guys i am having difficulty getting a rear oil seal for this 5718 i am restoring for a friend the seal is on the end of the crank shaft and housed in an aluminium case the one listed is 120x140x15 but this seal wont fit as the measure is 125x140x15 the seal removed is white in colour and the replacement is red but no one seems to have come across this seal before ? the engine also has a decompressor above the waterpump i assume to aid starting by hand ! NOT SURE IF THIS HELPS but this 5718 is dated at around 1973 also the pistons had 5 rings and is a 4 cylender any info would be great

ive checked it out for you and the proper seal is 120x140x15 so im not sure how yours is 125? i phoned a few people i deal with including bearing supplier and the seal 125x140x15 doesnt even exist!

not sure what to say
