This is the stock that it will be made from, took some hunting down as I needed steel not cast, this is a roller from an old pipe bender, but not today, job for tomorrow, Rick

great set of picks rick,never seen inside one of the pulleys.

Lovely stuff Rick!!!

Can't beat the old school tools

solarman216 · 27-05-2021, 19:40

Back on it today interspersing with directing tree surgeons, so this is boring the shaft hole aiming for 1Thou smaller than the shaft

solarman216 · 27-05-2021, 19:44

Bore done now the outside, had to do it in two halves as the bore would not quite go over the internal chuck jaws

solarman216 · 27-05-2021, 19:45

The finished bush about to be pressed into the pulley

solarman216 · 27-05-2021, 19:49

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 · 27-05-2021, 19:52

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

Looking good Rick. Bit of proper engineering.

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 · 28-05-2021, 16:52

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

panelbeater · 29-05-2021, 09:34

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.

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

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