Well big day ! all the machining is now done, , pistons, rebore, wrist pins, gapped the rings, .011 top, .012 second, oil .023 These rings a big mommas after the 2 ringers hey, BUT i'm happy, right now I just need to get a few passes under the belt before I get into the 2 ring shit again chasing the .01 HP increase

So now I'll strip the bottom end , clean check and reasssemble the lot.

I can tell when you are in the shed Johno,,the temp is always over 40 here when you do,,thanks for that

good one Genny, your right though, I must have some reptile blood in me.
going to spend some time today in the shed cos tomoz may be a bit warm for an old softy like me , around 40 deg it gets hard , the big choice xmas ham and beer or heat sweat and cursin,

yeah, but at least you blokes dont haffta "swim" thru the air down there,, (76* RH here),, ,,

Was going to just give the bottom end a petrol flush and put the top end back on but I thought after all the hard work I better do a nice job.
So pulled the bottom end apart for a check and a good clean of any aluminium crap from piston burn up.

All looks good, just have to swap the primary drive damper , I replaced the rubber dampers in the hub with hard arse solid plastic.

The bearings all look good, everything else aok

Wish it was back together like yours Finny

So case cleaned and blown off, the drive hub is changed over , time for some assembly.

Reassembled the bottom end after a good clean out of molten alloy, not sure why but it is making a rumbling noise, will have to split the cases again
bummer

Had a nice xmas yesty , ate too much drank too much

Found the problem today , had to split the cases again, found the rumbling noise was from the modified damper I put in , one of the roller bearings had a nick in the outer cage that made it sound like a gear problem, dont have time to try and replace the roller bearings, they are a bitch to replace so I put the stock primary damper back in.

The standard rubber need to be replaced with hard ares plastic when the 60hp engines start making close to 100 HP, the rubber dampers break up and get messy in the oil system, I'll be gentle on the throttle.

cases all cleaned up , gearbox sorted again , 3 rd time lucky

Now for the top end.

Forwards backwards land visits the mallee too huh ?

Cleaned up the alloy spray all through no 2 , cleaned up , checked vlaves

all done cleaned reassembled........again

giving the new barrels the big scrub 3 rd time lucky boys !
