You need some heat in that flange (lol) Weld a couple of nuts onto those studs, get the flange red hot and keep it red hot while you start working the studs out. Edit. Scratch that.

I thought of truck drivers.

Well done present day Matt.

Pop the pistons out of the calipers, give it a good clean up with a scotchbrite on the piston and bore. Carefully pluck the seal out and check there isn't a crud build up in the grove where they sit. If you're careful you can re use your seals and dust boots. Good blead up and it should be good. Pushing the pistons back and forward doesn't really remove the crud, it doesn't take much crud to make an imbalance either. Better living everyone.

Lols at the comparisons being drawn between this and other high performance engines of the ilk, such as K series, A series, and Holden 6.

@tintin What are those things?

@kws it will help your oil pressure issue. Engines loose pressure due to excessive clearance. Top end noise is probably the lifters bleeding down due to low oil pressure. I'd give it a try if it was mine. Thankfully it's yours though. Edit. Fair enough though if you want to upside. It's the perfect excuse.

Leave the engine in place, pull the sump off and sneak a set of big end bearings into it. If it hasn't run a bearing It's a legitimate fix. It'll solve your problem for a couple of hundred dollars and a few hours work.

Are the side bearings pressed all the way home on the carrier? (I’ve seen it happen before)

Have you calculated the effect of a better flowing exhaust? I theorise it may be directly proportional to the level of how hard it goes vs what it is

HQ holden.

No update for a while, I have been slowly pesting though. Made some new motor mounts, connected the hand throttle and altered the factory muffler to clear the bonnet and look more tractoresque. Annoyingly the motor was advertised as having a 1" crank with 1/4 keyway but it turned out to be 25mm with a 7mm keyway. No problem, I got the pulley re keyed and shimmed the difference in diameter with some coke can and lots of locktite. The pulley has provision for a grub screw to help hold it which I'll add when I find one. I also turned up a cupped washer to stop the pulley wanderin. I've used some bearings and another turned up washer to replace the missing belt tensioner. They might fly to bits, time will tell. So if I can get a new drive belt this week I should be able to go for a drive. In other news I visited Dubious Dave today who had found more Pwer Pony parts. Both belt guards which is super handy. They'll need to be modified but it's better than making new ones. Dave also came up trumps with a pair of mower decks. One is stuffed but it has all the mechanical parts on it. The other is in really good condition and appears to be compete. Perfect.

I'd be curious to know.

Why hello ThePog. I wonder what the total unladen weight of the Dynafari is in its current iteration?

Please 3d print a new exhaust soon. The suspense is killing me.
