had another tangent today, back to the clutch.

as I'm using a multiplate clutch I may need to limit the travel to save the possibility of clutch-cover's spring 'fingers' clashing with the top driven plate  wavey.png
 
possibly overthinking things but fail to prepare.......

easily sorted on a 5 as Mazda fitted a travel-limit to the clutch pedal with a rubber buffer, I removed the buffer from the pedal, drilled the hole out to 6.5mm & ran an m8/1.25 second tap through to cut a thread.

1wwpC41.jpg
this is adjustable for travel with anadjustable allen-bolt & locknut fitted.

more sillyness...

I've bought an AP Racing CP4623-90 master cylinder (evilbay again)

https://apracing.com...3-type?switch=2

with the intention of using as a handbrake cylinder BUT curiosity made me look at the clutch cylinder mount dimensions wavey.png

https://apracing.com...4-CP4623-cd.pdf

looks to be close as not to make a diference wink.png

the -90 denotes 0.625" / 5/8" /16mm bore and the Mx5 uses a 16mm bore so comparable cool.png

so looks like another braided hose to make then!


these cylinders are like the CP2623 type I'm using for the brake sustem so have the option of remote or fitted (screwed) reservoirs, will have to decide on the best option as a remote reservoir could make more room around the throttlebodies BUT maybe neater with a fitted reservoir - will bolt the cylinder to the car & decide...

new (old!) mastercylinders have landed, as they're used I'm going to buy seal / rebuild kits (~£13 each for genuine AP Racing).

Mg4TKp7.jpg
tried a rosejoint on one & offered against a clutch pedalbox, sits slightly off vertical @ about 11.30 o'clock undecided.png. nothing's easy is it?

7hizfxg.jpg

 

0Ao0hJN.jpg
also, is it wrong to sandblast & paint a spare clutch slave cylinder?

gbrkCun.jpg
or a propshaft...

at least it's clean where the flanges meet as are the bolting spotfaces smiley.png

fh5zAuQ.jpg
will find time to finish the delrin diff mounts this weekend hopefully.

mJKLrYV.jpg
due to a post on the fb / mx5itb page about cylinderhead port length I've taken a photo to add, obviously it'd be rude to not add it to this waffle rofl.png

pair of seal-kits & fluid reservoir ordered for the master-cylinders, going with one for clutch (needs the reservoir) and one for the handbrake although I might not have a lever connected just the cylinder fitted & plumbed into the rear fluid line to future-proof the car  :driving: 

also spent an hour mentally plumbing the brake & clutch systems, then ordered another bundle of fittings for a full braided-flexi line install :wallbash: 

 

22 'ends' plus copper sealing washers, banjo-bolts and a few metres of hose. chose plated steel over stainless due to my hatred of stainless as a fastening :yes:  

 

I'm refusing to count the costs for the plumbing (brakes & oiling) :trigger:

ebay strikes again...

cheap AP Racing 7 1/4" multiplate was spotted, a very cheeky offer was made & accepted pirate.png

when it arrives I'll see if its in better or worse condition than the 2 others I have  shocked.png

'ends' have landed, well I went to collect as somehow missed the courier yesterday superangry.png

2IwiW0h.jpg
some as stock spares and some to complete the car...

LFnFk6F.jpg
how the 'handbrake' cylinder will be plumbed, typically every fitting / thread in the brake system is m10, the fluid inlet on this cylinder is m12 so an oddity was needed shocked.png

now to decide where the handbrake cylinder will live, can be a bit tricky here as I can recess it into the gearbox tunnel in front of the standard handbrake lever (neat & out of the way) or do I go for a seperate lever to keep the cable and hydraulic systems indipendant 
obviously if I decide on a seperate hydro-handbrake lever this means deciding where it can live - another bloody decision rofl.png

more pieces for the jigsaw have landed.

the m/cylinder seal kits & reservoir are here, DemonTweeks via ebay and a few days delivery cool.png

pTOOOXK.jpg
will fit seals & look into making a cylinder fit the Mazda bulkhead & pedal...

4vJYkoC.jpg
another ebay sidetrack, AP Racing 7 1/4" multiplate clutch.

was cheap enough that I couldn't say no shocked.png
these can handle more torque than I'll be playing with and have a lower rotating mass than conventional clutches so a win cool.png

this one has the 'orange' pressure plate and 3-paddle plates so rated to ~310ft/lbs torque 

https://apracing.com...ly-twin-2-plate

I do have a few of these now, will use the best bits to build the 'one' wink.png
 
hu8ny4K.jpg

nYu1O5W.jpg

sectional design.
TGkBbCx.jpg

the seller advertised this as having been used on a normally-asperated Cosworth 'YB' engine so the driven plates have the 'Ford 1" / 23 spline.

I will be using the organic-faced driven plates  (made by Helix Atosport) as they have the correct spline size for the Mazda gearbox....

more tangental thinking...
 
bought some 8mm 'rosejoints'(rod-ends) to make anti-rollbar droplinks, pre made links are a little on the extravagant side of prices & I'm able to make my own for a significant saving - even if I add my time into the costing!
 
I've gone for 8mm Joints for cost & size / weight, I believe the standard Mazda links use 10mm fastners so I'll either machine some small 'tophat' spacer-washers to take up the difference or just tack-weld 8mm penny washers onto the wishbones  :wacko:
 
I'll drill & tap some 16mm diameter aluminium bar-stock to link a pair of joints with nylock nuts to fix the length.
 
as to arb body mounts, I'm looking at nylon stock and making simmilar to industrial hydraulic pipe clamps (also widely used in the kitcar world) 
 
more waffle to follow...

ebay again responsible for my financial losses....

bought £21 diff from a mk1 1.8 uk spec car

QNVdXH7.jpg
(photo from ebay advert)

collected it on Monday from Pembroke (ish) so a ~120 mile roadtrip in my B3 Passat tdi @ 60+mpg - cheaper than postage & an escape from the house so a result  :lol: 

I've stripped the diff from the alloy housing & its another 4.1:1 ratio so I'll pull the gears from the pigshead & prep the casings for whenever I 'find' the coverted 5.1:1 crownwheel & pinion   :yes: 

unfortunately the 5.1:1 ratio is about as rare as going to a car show and finding something unique  :popcorn: 

anyone want 4.1: gears?

more bits have landed, the ebay Fidanza adjustable cam pulleys.

5cskRlw.jpg
these are marked with 94018 that corrisponds with Fidanza's p/number for the Mazda engine, oddly these are different as one has larger holes in the central section than the other  :unsure: 

OX5Sej7.jpg

yc0kkZr.jpg
they've been used but not done much work as the outer-pulley's teeth have no wear in the anodising & just the lightest hint of marking that tallies with a belt's position...
the centers have witness-marks from a cam-bolt's washer and also from the end of a cam.

I'll strip, clean & degrease then locktite the bolts into the outer section, also I'll fit new washers as the ones fitted are dished / deformed from use.

now time to 'find' some cams, these will not come from ebay as 'pre-loved' cheapies so thats going to be an expensive purchase (will order a pair of new ones as I doubt the standard cams can be re-ground to the size I fancy :P )

Damn you evilbay  :wallbash: 

saw someone selling new genuine Mazda brake discs, the partnumbers looked to be mk2.5 sport big brake type so in went offers.....

I'm expecting 4 different sized & fittment discs to arrive  :lol: 

I have a set of 'sport' calipers in the shed, will dig them out & inspect.....

also, this has (hopefully!) decided on the disc / caliper & wheel size :yes: 

also, back to the engine, made a a decision on timing reference, going for the Mazda 36/1 timing wheel that fits between crank-pulleys with a sensor mounted on the oilpump / front cover, as fitted to the 1999-2001 Mazda Protege.

p/number ZM01-11-408

UZb8KVz.jpg
when it lands I'll have to re-measure & machine the pulley-setup I've adapted as theres now an extra ~3mm to consider  :doh: 

NEXT!

decided there was zero chance of buying a Setrab AN12 oilcooler so going the el-cheapo method with one of my 'stock' 1/2"bspp threadded serk or mocal items.

fqgGv96.jpg

 

AN12 male to accept the pipework and 1/2"bspp female with a tapered seat.

its the little things that count up the pennies, thats £23 in that photo  :blink: 

and I didn't buy them because of the colour  :lol: 

now to buy pipe & 6 or 8 fittings with pipe @ £10-15 / m and ends @ £10+ each  :rolleyes: 

^^ thats for the scavange side, will be using the cheaper 1/2" bsp hydraulic hoses for the pressure side :)

back onto the Bias braking again, been looking for a Tilton or AP Racing bias adjuster for a while, no other reason than snobbishness as the 'el-cheapo' generic adjuster I already have will work fine anyway  :blink: 

anyway, ebay again responsible for my financial irresponsibility & today a secondhand Tilton adjuster arrived  B) 

unfortunately, to get it cheap enough I had to buy a complete pedalbox with the adjuster, ballance-bar and a pair of Tilton cylinders BUT these will either be re-purposed or sold...

more junk in the collection  :o

I've just made an offer on a Hayabusa drysump kit as I need a few fittings and having another pump to choose whichever is better makes sense, also because it was a cheeky offer so cheap enough to have as stock.

lsO3nei.jpg
the kit as bought, the Hayabusa specific parts will go on a shelf for that 'rainy day' but fittings & possibly the pump will be considered for the Mazda install  :wacko: 

98b5nnN.jpg
Pace 3 stage (2 sump scavange & 1 pressure) pump...

or do I fit a Hayabusa engine in the 5  :o

yup, sbd do a bolt-on 200+ kit that opens up a standard motor  B)

Hayabusa drysump bits have arrived B)
 
the pump is actually a bigger version of the one I already have so I might use that :wacko:
by bigger I mean it has longer 'scavange' sections so in theory will be able to 'suck' more from the sump / crankcase - although nothing is free and more pump / suck means more power to drive it :blink:
 
internally it's good, theres some scoring but nothing drastic (I've never seen a used pump without any!) so I'll do some measuring and maybe a test run with a bucket of oil & a drill to turn the pump :)
 
more fun.....

Posted Yesterday, 10:27 PM

the 36/1 timing disc has landed, bought through ebay USA, cost £26 delivered & between purchase / delivery was 8 days   B) 

maybe I could have sourced through local Stealerships but my experience is its probably cheaper internationally! :lol: 

1Hi5gxb.jpg

missing 1 tooth but easy to remove another for 36/2 profile  :wacko: 

also started collecting oil pipe 'ends, AN10 (pressure) and AN12 for scavange, also fighting the urge to get a Laminova oil / coolant heat exchanger as opposed to a conventional oil  air cooler radiator. - more money  :wallbash: 

NEXT.
