Enfield's Rebuild

[EvilEnfield]

Yeah I thought so. I think I'll leave it for a week or so, just until I calm down.

Alternatively tip the whole bike upside down - somebody did it on here and it worked.

Or try flushing it out with some derv (but throw some oil down the bottom soon after flushing to save the bearings from drying out.

[EvilEnfield]

Funny you should say that, I was just thinking it would look better upside down, albeit at the bottom of the hill and on fire. I don't think it will flush, I can't turn the crankshaft in either direction, it must be perfectly wedged somewhere in the bottom, what do you think would give first if I gave it some welly on the crankshaft? Also is it a straight path out of one of the hole on the bottom if it does dislodge? I can't see or feel how it would drop down.

80-=81 750's are known for tearing up the ex cams. Has to do with poor oil flow. you should drop the oil pan and shim the oil pressure relief spring. Use synthetic oil and change it often

[hampshirehog]

I think if you can free it from whatever is keeping it from getting to the bottom of the crankcase then it will settle out of the sump with the plate off. I've rescued a few GS(X)s where things have gone down the cam tunnel and they have come out fairly easily with a bit of jiggery-pokery. However, that is all on GSs with roller cranks - things might be tighter down below with plain cranks, I'm not sure.

[EvilEnfield]

There are very few holes under the crank shaft for it to fall out of, I think I'm going to save up for a gasket set and exhaust cam shaft, have the engine apart and paint it. I can't believe I was so close to riding a couple of months ago and now I'm done in by a bolt. Never mind, these Cornish hills should be a giggle come winter, might trade it in for a Ural Gear Up.

[EvilEnfield]

My gasket set has arrived, woo hoo, but I've been reading the manual (for an 8 valve, I haven't got a real one) it says I need a special tool for taking out the 8mm head bolts, is that true or will an 8mm deep 1/2" drive socket be ok? I don't want to start and then be stuck for tools. Are they really 8mm or is it a typo? Tiniest head bolts ever.

[hampshirehog]

If you don't have the special tool all your children will be born of the devil and your hair will fall out........

No special tools required. The Suzuki manual is available on Cliff's site for free if you haven't got it yet. You'll just need a torque wrench when you put the cylinder head back on.

[EvilEnfield]

Cheers HH, I'm afraid you're correct about my children. Which manual is it on Cliffs site, I downloaded the one I thought it was and it was different, unless I clicked the wrong one, I'll have another look actually.

http://www.mtsac.edu/~cliff/storage/...50_16valve.pdf This is the one you need.That list can be a little much,missed the one I needed for mine to.Asked here and had my nose nicely pointed to it.

[EvilEnfield]

Thanks for the link, I thought that was the one I downloaded, must have clicked the wrong one.

Anyway, I've got the head and block off, but I heard that bolt fall as I lifted the block away. I'm sure it's sat in the bottom somewhere now but I still can't get at it, so, my new question is- can I split the case without removing the pistons, governor and clutch etc? I think if I could then I would probably be able to just lift the top a bit to be able to get a magnet stick in there. I hope so.

[hampshirehog]

You can leave the pistons on but you have to pull the clutch off. I don't know what you mean by the governor.

Is the engine out of the frame now? If it is that bolt will come out of the sump with a bit of a shake.

[EvilEnfield]

I was trying to leave it in the frame, I don't know why, trying to back track as little as possible I suppose, but it's nearly out now, I think this was just one big act of Suzuki God to make me clean and paint that damn engine, would probably never have happened if I'd just done that in the first place. Curse my laziness.

[EvilEnfield]

Bolt is out, arms and shoulders are killing me, engine is being de-greased ready for painting, can't find my piston ring compressor, but I only have one anyway, or adequately sized hose clips. Anyone have any back yard tips for getting the pistons in without any proper tools?

I'm going to order some ring compressors, too many cylinders to mess about with fingers.

I found this on the floor, I'm assuming it is from when I was shaking the engine about or when I removed it, but hopefully it's just from my car.

Does anyone know what this is?

I really do need a better camera.
