Re: Assessing an unknown engine

I thought Mike had retired? Hopefully he still wants to share his experience. Don't the pistons pass through the cylinder holes in the block halves? That lump of alloy jamming the piston should tap back into the case where it dropped in from? Do the rods move on their big ends or tight? When my 3.2...

Thanks, that's most kind of you, (if it comes to that).

I might drop Mike Bainbridge a line as I'm sure he has dealt with this eventuality on multiple occasions.

Re: Maddening Running Issue

Sell the fuel tank on ebay (or on here). That will fill a gap for somebody, and people value originality.

Re: Assessing an unknown engine

Perhaps you’ll need to drill or cut the piston to get access to the rod bolts, ideally without damaging the rod? I contemplated that but I'd have to do both, and one is a good piston (one broken). A new oil pump driveshaft is £60. A new piston, more. Although in truth, I'm probably replacing all th...

Re: Assessing an unknown engine

If you can get a set of three pistons off and then release half of the crankcase you can maybe get to whatever is jamming it, or to the other rod bolts and then it should come apart. Just put the engine stand connection on the side with the stuck pistons pointing towards the floor and leave the cra...

Re: Assessing an unknown engine

Being entirely satisfied that it is the seized oil pump that's preventing the crank from turning, I formed a plan to break away these circlips and see if I can slide the centre of the oil pump driveshaft off its splines in one direction, allowing the crank to turn. https://uploads.tapatalk-cdn.com/2...

Re: Assessing an unknown engine

I have no clue where this is going because 3 and 6 are irremovable but it feels like a step forward in some sense. https://uploads.tapatalk-cdn.com/20240425/5322ec617f8c5847f6ded8c425888443.jpg https://uploads.tapatalk-cdn.com/20240425/723cb5e4c3b251471396336c44a4738d.jpg Sent from my SM-G988B using...

Oil pickup contains metal flakes - feels like magnesium.Image

Re: Assessing an unknown engine

Ok what should have been obvious before has now dawned on me. The case can't be separated with the pistons on the crank because the pistons will not pass through the webs of the case. So these wrist pins will have to come out by hook or by crook. One option I have is to remove the circlip from the I...

Re: Assessing an unknown engine

Next little obstacle - I can see a piece of metal jammed alongside this piston. It's dropped into there while the engine the other way up.Image

Re: Maddening Running Issue

Nothing there overly concerns me. I'm more hands on than most, so this wouldn't be for everyone. But if it were me I'd chemically or electrically remove the rust then epoxy line the tank. It looks very thin, maybe less than a tenth of a millimetre thick on a tank wall probably 1.2mm thick. I'd be mo...

Re: Assessing an unknown engine

I followed those with the 23 case nuts and as per Dempsey's advice I left a few on loose to prevent the case half, crankshaft and pistons falling on my gouty toe. I turned the engine loose side down and I set about the perimeter with the plastic hammer. Soon one end was separating. https://uploads.t...

Re: Assessing an unknown engine

These through bolt nuts were surprisingly loose. But all consistently torqued so I assume that's the right setting. As with the case nuts, I broke them free with the socket or spanner then spun them off with the baby impact driver. https://uploads.tapatalk-cdn.com/20240424/bcb87e0560c25fbb72124e72c3...
