the bores does just want reboring cal...no damage just over wear lip at top of the bore where rings top out

slob · Guru

Looks like the same thing that happened to mines so would love to see the work being done. I got one of those double lipped seals of simply bearings. How will I know which way round is the crank side.

NORFE · DTR Trusted Engine Builder

if u look on ur old seal it says outside on 1 side, the lips are different angles just compare it to the old 1

slob · Guru

I destroyed the old seal getting it out and threw it away lol. I will take a closer look at it later on.

norfe text me today saying he has the barrel and the crank back from where ever he sent them, so i assume he will be busy putting the engine back to gether over the next week.
i am sticking a pic of the engine norfe recived so you guys can see the work this guy does.

Great work as always., Don't mean to jack the thread, just need some clarification. Have you ever found that this bearing can go in by hand? I had to put a bit of Lock tight on and it seems sloid it's a 6302. Just want to know befor I begin building lol!

int that the bearing the selector drum goes thru??? is that the correct bearing as the bearing on the selector drum is fitted on b4 the detecnt star is welded on ?????

slob · Guru

I see !!! knew I was being a total idiot lol and something wasn't right. Been so long since I stripped the enggine and the bearing just went In there like it was suppposed to be there. My mind set has been hole = bearing lol. Would have been in for a shock when I went to put it together lmao.

NORFE · DTR Trusted Engine Builder

gunna say u plank u boggled my mind then ha ha, yhat bearing is the output shaft int it in the right casing..heat it up with blow torch to loosen the thread lock and tap it out

slob · Guru

Ha Ha lol par for the course for me lol. Its one of the balancer shaft bearings cause I had two of the same kind for some reason, thats what started the confusion. It actually fills the hole perfectly. I was speaking to an engineer at work who hadn't seen it and he said a bit of thread lock will do, won't tell him the truth though

Only need to use Gen for head gasket, elsewhere pattern is fine

NORFE · DTR Trusted Engine Builder

You have to make sure the surfaces are clean before applying the gasket.

The engine is all done now, so i need to get it sent back, but had to pay for a driving corse because i got caught using my phone whilst i was driving, so that took my money i had stashed away for postage. when the engine arrives home i will post some completed pics (or norfe might beat me to it). just a huge compliment in norfes direction, been incredably easy to do buisness with, allways been avalable to help when i had stupid questions etc, if any of u guys are considering norfe for your engine works, then do it. u wont be dissapointed. Thanks again mate, and dont forget to get yourself some "tizer". u northan boys love tizer right?
