Mighty Shee Posted December 20, 2019 Report Share Posted December 20, 2019 I had new bearings installed in 4 mil got rid crank. I place it in the bottom half of case and it spins freely. I’m doing this without the top half of case. Once I install the 2 new crank seals the crank is a bit tougher to turn. I did pack the inside of the seals with plenty of grease. Is it normal that the crank would be a bit less smooth to turn with brand new seals? Also, I ripped the darn rubber band that goes around the red piece in the middle of the crank. What’s that rubber piece for and can I still install the crank with that rubber broken? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

the boris Posted December 20, 2019 Report Share Posted December 20, 2019 That rubber should prevent mixture leak between the left and right crank chambers I think.Sent from my ONEPLUS A3000 using Tapatalk Quote Link to comment Share on other sites More sharing options...

You can buy replacement one, no big deal.Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...
Keno Posted December 20, 2019 Report Share Posted December 20, 2019 The pink thing is a labyrinth seal. The orings keep it and the bearings from moving and chattering. You can just CA glue the oring back together, or buy a new one. You can also just smear motoseal around it. Quote Link to comment Share on other sites More sharing options...

If I cannot find a new one in Southern Ca. today I guess I’ll just try using CA glue to glue the two ends back together. I’d rather find a new one to buy. Anyone have any info on my seal question? I’m thinking new crank seals mean a bit tighter crank seals for at least until they are broken in.

Keno Posted December 20, 2019 Report Share Posted December 20, 2019 Yes, perfectly normal for the oil seals to make it a little harder to rotate. Quote Link to comment Share on other sites More sharing options...
