Mrs 3Ltr stopped today

[solarman216]

The finished bush about to be pressed into the pulley

 

[solarman216]

Pulley and fitted bush to be pressed onto the alternator shaft, took the full 6 tonnes of the press to push it home, well pleased with that as no need to weld

 

[solarman216]

The finished job, and the Mrs is now mobile again, Rick

 

[Flying Torquewrench]

Looking good Rick. Bit of proper engineering. :thumbs

OK so been doing some research re free wheel pulleys, the upshot is this, because serpentine belts have a self adjusting spring loaded pulley, which is crap, they had to find a way of stopping the pulley jumping under certain situations, idling is one, so they came up with the naff idea of a rubbish free wheeling pulley which smooth's out the the irregular crank rotation on the alternator as it's mass is quite high, never had a problem with fixed adjustment V belts, so next mod on the Mrs motor is fix that ruddy springy pulley and make the alternator the adjustment point, Rick

pullys are on line from 25 and full alts from 80,just saying for any others that might need.yes good job there rick,my lathe would not go that big as its more a model engine lathe.

 

[terranosaurusdoug]

Nice one Rick, I wish I was set up like that :thumb2

 

[panelbeater]

can i suggest that a spare belt be carried as making it a fixed pulley will put the most strain on the belt as its design is not like a v belt thats designed to stretch and dig into the v for extra grip under load.

Nice one Rick, I wish I was set up like that :thumb2

Got a guy down here with a mini digger, the bushes in the end of the main arm were none existent and so the bore had worn so much new bushes were not the answer, so he produced a lump of metal that had been used as a slide hammer, what was required is 61mm ext diameter by about 100mm long with a bore of 33mm, problem is the hole that had been drilled for slide hammer use is not central or parallel, started to machine it up today carry on with it tomorrow, if anyone interested I can post some pics, Rick

 

[Flying Torquewrench]

What lathe have you got Rick? Looking for one myself but not sure if I go second hand old school or brand new.

 

[solarman216]

Only a Myford Super 7 with screw cutting availability, sadly not big enough for skimming brake drums or disks but I would not want to be without it, Rick

 

[solarman216]

There is one on Ebay now for £1600 with stand, looks good, Rick

 

[Flying Torquewrench]

Very nice. The old British made lathes are certainly commanding a high price these days. It is difficult to spot a diamond in the rough that is nice an straight.

I have been looking at a Warco Gear Head lathe. Chinese made but Warco’s service is very good.

 

[solarman216]

Mmmmm lots of bells and whistles, depends on what you want to use it for, Rick

 

[solarman216]

Same digger guy gave me today a chunk of metal that is apparently a track roller for a 3 ton digger, it had been welded up and now needs machining to accept a couple of bearings, will post a pic tomorrow, not sure I can do this on my 63 year old machine, yes looked it up yesterday, nearly as old as me, Rick

 

[Flying Torquewrench]

Mmmmm lots of bells and whistles, depends on what you want to use it for, Rick

I make/adapt a lot of the attachments for my digger. Being able to make my own bushes, pins etc. is so much more convenient. A lot of the bells and whistles won’t be used but the one I am looking at has a 910mm between centres. Rather go for a bigger machine now and be able to “grow” my work into it then ending up buying a bigger machine later.

Put up some pics of the work on the digger when you have time.

How is the London cab coming along?

 

[solarman216]

London Taxi went home a week or so ago, to have the MOT done once the steering has been fixed by a specialist Taxi engineer, Rick

 

[Flying Torquewrench]

What was wrong with the steering? Not often that there is something that you can’t fix.

 

[solarman216]

This is the ghastly lump of metal that my mate thought I could put right on my lathe, this indicates how out of true it is, look at the gap between tool and job

 

[solarman216]

Now look at the gap
