what did you wrench on today??

No wrenching involved, but last night I helped recycled64 install a headlight bucket on one of his 650s.

He was a little apprehensive about the tangled mess of wiring that had to be re-arranged, we sorted it out in the process. :D

I wrench on this, when I'm not operating it....

11,250hp centrifugal compressor, GEC, circa late 1950's.

11,250hp ! Here I though our 75 and 100 HP ones at work were big!!!
Any other specs on that bad boy? CFM, Hours, etc?
 
32,000cfm, 330psig discharge pressure. 680A @ 7200VAC. Pulls 1000A at start-up through an autotransformer reduced voltage start. Sometimes a few lights go out in the plant when I throw the switch.

1000gal lube oil.

200GPM oil pump.

1200 rpm synchronous motor (weighs 30tons and has its own liquid cooling system). Power goes through the first 11,000hp planetary gearbox to spin the first 7 stages (in the blue section) @ 4500rpm. This feeds into a second 3600 hp planetary gearbox which spins the last 3 stages at 10,000rpm. This section is uncooled, and as you can see by the paint, gets rather hot (approximately 400F discharge temperature). I had to pull one of the main bearings a few weeks ago to get it trued at our machine shop. It was an 11" diameter Babbitt bearing which had gone out of round. The big square boxes have 5 heat exchangers in them each (20 total). I had one off last week. Each is 10 tons.

And like any good British machine, the fasteners are a mix of Whitworth, BSF, and BSP. Ask me how much I hate trying to find which wrench is the correct one. Most are labeled in both BSW and BSF, just to be extra confusing. It's very well built and has proven itself over 50 years though. It's also a marvel for ease of maintenance. I can have the main gearbox out in half a day, and one of the cooler boxes off before morning coffee.

Roger, I think this thread should be closed and another started for those who wish to post on this subject. Nothing any of us can post even belongs in this thread after yours.;)

I was going to post about spending several hours removing the front & rear axles from a friend's ancient Honda ATC. Why, of why won't people remove the axles and brake drums from this stuff and coat the spines and axles with waterproof grease?????

I had to cut the drum around the center hub, remove that then use my air chisel to split the hub into three pieces before it would come off the axle. The bearing retainer bolts just spun because the weld nuts were torn loose from the retainer, joy oh, joy?

It took a 12 pound hammer with blocking to remove the front axle and even then it had to be cut. Same cause, no grease and decade of water...


See what I mean about my post? It sounds like baby stuff....:o

I have a Third Class Power Engineering Certificate so got to play around with big stuff like that but never an air compressor that big. I guess when the earth stops and the air all flies off into outer space, we can phone you to pump the earth up again? ;)

Great posts, we immature "little boy types" are in terminal envy. Tim Taylor was right!:D

I'm glad it's not just me.
 
I *finally* polished the paint... and got a lot of it mounted back on and I shouldn't have to remove it again before getting on the road :D

at this rate i think i'll have managed to get across the pond to your little island before you've finished that bike ;D
 
Gotten too cold out here to do any painting so I just swapped out a battery terminal and the hood supports on the Jeep then fixed the front gate to our place. Need to finish replacing a switch in the living room ceiling fan later today.

Haha mate it's nearly done... Getting it ready for registration by the end of November is the target and it's looking quite possibly if not likely... ;)

And do I see correctly you sold your 400? :eek: What's the go?

Plenty in my rebuild and paint threads, but since you insist :p



Huuuuge thanks to Larry (nvr2old), Dale (rustybronco), Johnny Drummond, MisterCinders, Paul (laverda1200), and all the others on here that have lent advice, tips, and encouragement along the way. My lack of skills has left it not quite so perfect up close, but it's far far better than anything I could've done without that help, so thanks again guys! :D

(Don't mind the disc and tyres, they're being replaced real soon)
 
haha 10 footers are okay, all the more reason to stay ahead of everyone haha.

ya, sold it. didn't intend to keep it long. sold it for more than i paid for it.

riding my friend's cbr900rr at the moment. planning to get a 600 sport next season.

Aaah I see! In that case well done :D

We're just coming in to summer here ;)
 
Managed to move my bike into a friends' garage for the winter. Now I finally have a dry, heated workspace. Let the work begin!
 
Pulled the alternator on a 2000 'Chrysler' intrepid with a 2.7L.

Alternator is good, B+ from battery to alt is good, the wire to the field circuit measures okay (battery is disconnected). looks like the wire from the PCM to the alt could be open or possibly a driver (transistor) issue with the PCM. I need to disconnect the harness at the PCM and check it. (power is fed to the field and the PCM grounds the circuit)

If it's an issue with the PCM, I might have to rig up an external regulator for the field circuit.

Yesterday, helped Vmass adjust valves on his bike, then synchronized the carbs.
His bench sync was so close, I almost didn't want to try to get it any better. :clap: :clap:

Before we moved to changing the clutch springs, he mentioned a rattling that he had heard. Fired up the bike again and verified some extra noise. After pulling the clutch springs, we went ahead and pulled all the fibers to measure them (all are around 3.0mm :dancing:). I looked at the large hub nut, and even though the washer appeared to be properly bent up to lock it, it was VERY loose. After flattening the lock washer, I was able to turn the nut almost two full turns. :eek: Had to buy a socket to tighten the nut properly, then cleaned the oil level sight glass and re-assembled.

We did not get to the tire change and caliper rebuild that we had hoped to do, but he feels better having the valves, carb sync and clutch done. :D

I am certain that he was very appreciative.
