I have just stripped & cleaned this gearbox and it is in good condition. I'm now trying to decide whether to just put it all back together, as all the bearings etc. are good & no wear on the shafts, or to splash the cash on it & renew some of the parts. https://i.postimg.cc/svKw4QfZ/2024...

Excellent. Thank you Peter. Looks like a good turn-out.

Anyone take any photos they can share?

I recently watched this video on YouTube.... https://youtu.be/fVYZmeReKKY?si=I4J0E2Uqx7Akjj74 to make your own Evapo-Rust alternative. I haven't tried it yet but, at a fraction of the cost and longer lasting, I will give it a go. Recipe: Per 1 litre of water. 1: 100 grams Citric Acid. 2: 40 grams So...

It's just a push fit. If it's too loose you can use some anaerobic sealant like Loctite.

Apologies. Must have gotten out of the wrong side of the bed.

FFS. I measured a used crank which was probably warn. I used a vernier to check the measurement (which isn't the most accurate tool). I may have even rounded to the nearest millimetre. The crank is going to be 3 inches, as it is imperial. 3 inches is 76.2mm.

When I measured the seal ID, I measured the smallest diameter which is the flexible portion, hence why I said approx.. When ordering a seal you need to know the diameter of the shaft it's fitting over. As Steve alluded to, the engineers have taken the flexible bit into account so if you order a 3&qu...

Erm! yes. I actually have a brand new one from Rimmers sat in front of me.

I see.

The end of the crank is 76mm.

The seal has an OD of 95.5mm. and an ID of approx. 72mm. the width is 9.5mm..

These seals are readily available from the usual suspects, Robsport, Rimmers etc. or do you want to try to source one from somewhere else?

Part No. 143148

OE is definitely 7/16" UNC both ends. The UNC is needed, where it screws into the head, as it is going into Ali, which has a courser density. The other end, however, would probably be better with UNF. ...but they don't screw into the head Mart, they screw into the block! Doh! sorry, senior mom...

These are the bolts for the rods.
