A kind of naked front end picture whilst the engine is being put together and a close up of the remote gear linkage for those who wondered how it worked

Brief update, new head gasket Head on and torqued up!

Richard, Yes it was from Kevin, great kit of parts. All the shim gaskets for setting end float as well as seals, piston, con rod. All gone together really nice. Shame the engine has seen a hard life and zero maintenance. The oil was just a sludge and massive amounts of carbon built up everywhere. On the same advice I've left the gears out. Bendy will work but never flat out. Its a tickover to 1500 rpm kinda machine. Plus I might run it straight stack just for maximum effect

I didn't measure the bore, visually it looks good. If i spend any more money in the engine I can buy a whole tractor with an engine. Currently the £170 I have in it will now not burn oodles of oil or drip everywhere! Everything has been cleaned in petrol, blown with airline and then cleaned again.

Tidy work

yes they are out! Shakin horse might have some competition

Well it's been a busy day! 6am this morning We drove 30 miles up to Horton in Ribblesdale to do one of the three peaks before breakfast! Then it was back to the rebuild. Here's the crank and cam out... the infamous balance gears - which run on small needle bearings - same as the high low idler in an 8 speed! They are incredibly loose - I'd say the bearings were shot! after a good degrease, the valves were lapped - both in pretty good shape. Probably the gallons of oil that have been through them! them the bore was honed, again it's in great shape at the top but a little worn where the oil rings have been. a little light scoring cam back in place, note the timing mark - and the ACR lobe to the right - it's a little worn but still functional! Also the two pins to the left where the balance gears lived crank back in and timing marks aligned that's pretty well it! Piston is in, but no pics - just lots of swearing

looks an interesting piece of kit, how old is it?

Ah yes I see a resemblance, I did hear there was a fracas over food that evening, but the missus sorted it... hows the black eye

not sure what I was expecting - maybe flames and big holes in the ground where you had spun the wheels!?!

interesting...

Omg, how loud!! Bet you are still deaf, can we have subtitles on the next video? I won't be able to hear anything! Well done.... How long then before the first donut?

Looking good Norm, next you will be wanting stickers

Hi, A photo would help. My brother has a mountfield 25 he restored last year... It was our first ever ride on in 1982 Btw where in north yorks are you?

looks a useful bit of kit!

I think it's got djs name on already, only 10 mins from his

great work Richard, looks like new!

Apparently not, most engine rebuilders say leave them out. I'll let you know if there's any vibration...

I think the challenge is on Norm

it's coming out - it's what makes most of the rattle on a k or magnum. Especially when you rock the crank to feel for big end wear. They are always really rattly!

Richard, like I said - just about within tolerance for what I'll be using it for. It's not going to be worked hard, but does need to run properly and not haemorrhage oil. Either through drips or burning...

Here you go, First instalment The piston and rings look reasonable, but closer inspection shows heavy scoring and erosion due to being coked up. I thought it was oil ring stuck to the plug, but apparently not. From the bottom end, some light scoring on the big end journal. It's 4 thou out of round and 6 thou out at its maximum. Just within acceptable tolerances for what I'll be using it for. Pic shows cam to left and balance gear to right, which will be coming out. I dislike the rattle from it!

Looking good Sam

I was dead lucky, no Idea when I'll get another good day.

Great machines and pics, thanks for the pics
