hello there, Quick question for the tractor fans out there. Earlier in the year I changed the cylinder head o`rings, is it worth re-torqueing the head nuts as it says in the rotax manual or is this just done after the first 300 miles? On the engines I normally work on we never re-tighten. Mike_604 |

May be worth checking, is it leaking now? I had to make a special tool to torque the bolts up as the 2 bolts cam belt side are in a recess |

No, there are no leaks; its all good in that respect, just didnt fancy peeling off all the silicon behind the cam belt plate again, especially if those who had done the job before did`nt get anything on the nuts. |

I checked mine after 300 mile and they were still on 35 Nm, i wouldn't bother unless you see oil. Theres a proper spanner to fit on the torque wrench for the rotax motor on shoply £5.25,just type in cylinder head wrench for those interested,handy peice of kit especially for the lower rear bolt. |
