As you have the engine and spare gearbox, and there is plenty of inspection holes in the bell housing, trial fit the box onto the engine without the clutch and that way you could look into the input shaft through on of the holes to see how it sits in the bearing in the flywheel, as you would be able to see how much of the input shaft actually sits within the bearing, or isn’t as the case maybe, and while the box and engine are bolted up out of the car you could inspect the fitment between the adapter plate and bell housing from the inside of the housing and externally ?
Lots of good analysis. Spigot offset seems mist likely and combined with a bit of misalignment. Need to make sure non of studs protrude or it won't tighten up properly - put a steel ruler across. Like the comment from other poster about the plate being a bit thin round the bottom - hard to understand without being able to see the whole thing - have a look at that and ask Jonathan. Perhaps have a go with what you have then think about improving the plate design with Jon. Release bearing plan sounds good. Look forward to seeing how these challenges all turns out, and the next video. Enjoy! . . . and more importantly - Happy Birthday!
Idea to check the engagement of the input shaft in the input bearing: Bolt/mount the gearbox up but with the grease still packed in the bearing, flush with it's face. When you remove the gearbox check how much grease has moved. Also, I think i'd rather "caress" the sump with a soft mallet than grind it. Ally is pretty soft, should get you a few mil clearance without cracking. Happy birthday M8
Sounds like great customer service I’ve been thinking of getting one from there for a while now and now my mind is made up thanks for the recommendation
Happy belated birthday ,, for your clutch release arm adjustment you could just shorten the pushrod on the slave cylinder or slot the slave cylinder mounting holes so you can slide it away from the release arm to adjust the tension on the thrust bearing
Just shows how a number of very minor things can add up to a more serious problem. The Perfect Storm I suppose. Great video by the way. Very informative and extremely well explained 👍👍👍
Hello Marcus. I fitted an rx8 box to my escort and I was told I had to machine 15mm of the gearbox bellhousing to make sure the input shaft was will engaged correctly and for clutch to have the correct pressure. It might help you
adjustable rod from the slave cylinder to the fork arm just like they had with the mk1 mexico cortina most of the early fords was like this thinking about this most early hydrolic clutch systems had them to set them up right.
I'd say that the plate isn't flat on the block. Reason being is how much it bends out at the bottom unless its al bolted down. It suggests its being pushed out.
We always used a bit oak shaved down to spigot bearings diameter as a punch caused no damage and easy to get out. Happy Birthday and will you need a adapter fitting for zimmer frame.HaHa
Why not just make the slave arm post adjustable and leave it? Take the current post out & drill and tap with a lock nut - assuming you don’t need to machine the casting to make clearance.
It's great to find things out about the gearbox and on ur backplate. Could you weld that dowl near the sump on to the back plate so it does not push against the sump? When bolting the gearbox to the engine.
Welding the bottom dowel to the plate is defo an option. Jonathan was saying to me that alot of people do that BUT it can sometimes make the bolts a little sniff to screw in. But if I leave the top one un-welded (seeing as Carlo is modifying it for me to make it easier to use) it should be ok. 👍
Happy Belated Birthday mate 🎉👍 a good few things to be trying there, hopefully you'll get it sorted!! As other comments could you not weld the lower dowel to the plate? Also try a wooden dowel to pop the bearing out, that's the same method we use 👍
Thanks for the advice and the birthday wishes mate! 👍 Defo considering welding the bottom dowel on and I actually have a spare input shaft that I can use for the bearing but totally forgot when I filmed this video
Happy belated birthday 🎉mate , the hot wheels would be a great idea to do for sure , I just got the boulevard rs1800 mk2 and the zebra striped escort cossie , I got them imported from Thailand from Gavin squint and it’s mint
A marcus am doing a ztec focus engin with a rx8 box.a bud what did you did for flywheel and clutch and preasure plate .and your mazda box mount.and that adapter plate.hit me up with that info .please and thanks.
Hi Marcos , with the changes in the ULEZ regulations for London coming in to force next month will you be getting a ULEZ compliant car for day to day use ?
Hi Marcus, my backplate is thicker than yours and I welded the threaded dowls . Mine fouled the sump, I took some of sump off for clearance. Centrifugal slave cylinder is a good idea as well.
@@marcushayesford the other thing I didn't mention, dont go playing with the fork pin, it's alot of trouble wasted time, when all you need to do is shorten the slave rod to gain end float or make a slave rod adjustable, the first process is so simple. With the slave cylinder in its rested position, the original slave rod gives you no end float, so shorten until you get end float, can do this with gearbox out👍👍
Happy birthday mate, get yourself an old input shaft to get spigot bearing out,you can also use it to line your clutch up when refitting, nnever failed me yet
Happy birthday young fella, 30 year's ago I was working on my mark 1escort but it was a 13 hundred but changed carbys and exsort's and put a hot cam in it was ok for a bit and mag wheels on it , but now been working on my Rav4 it's been a pain because of not checking parts properly I got the wrong part's for the transmission but it was ok what I looked at , then I was waiting for new engine mounts but the delivery company lost them , lucky I got my money back but will still get new one's later as just want it back on the road, just wished I didn't start with it and spent the money on a mark 2 escort as I can fix those faster than the rav4 but that's life with car's, and hopefully will start saving for later project's for the future??
Hi mate. When you've got all your new Bits on. Do some measurements to make sure that the input shaft is sitting perfectly in the spigot Bearing. Don't Guess it. Socket & short Extension is also good for Removing spigot Bearing. Love the Videos.
You should be able to change the input shaft bearing when you're sorting the clutch arm pivot. Should be behind that bolt on cover I think. Happy Birthday from one Gemini to another ♊😁
Hi Marcus, belated happy Birthday ! The two counter sunk Allen screws near the head which have caused splitting of the adapter plate probably have a different shoulder angle to the angles machined in the plate, so when the Allen screws are tightened they cause a wedge jacking effect which cracks the plate relieving the imparted stress.. This can be checked by removing the plate thoroughly cleaning the screw holes and the screws,, apply engineers blue to the screw shoulders ( very light smear) fit in the holes and rotate by hand. a full smear of blue should be seen in the plate counter sunk holes. Your precision Engineering work shop could check and rectify as needed. Put a straight edge across the bell housing, then measure how much above the line of the straight edge the input shaft stands proud , I suspect that the input shaft spigot bearing shoulder is too proud and pushing the spigot bearing into the crank shaft, if too long it will be loading not only the gear box input shaft bearing but also the crank shaft thrust bearing hence its importance, fit the new spigot support bearing slightly sticking out from the crank shaft and bolt up the gear box, if the spigot bearing is pushed hard in after gear box removal, suggest you contact the adapter plate manufacturer for further advice ! The 4 paddle clutch plate centre is mullered because it has no springs to absorb shock loadings, the splines are softer than the gear box input shaft splines so are wearing to the point of slipping. The transmission shocks usually absorbed by the clutch will manifest as above and premature failure of the gear box teeth then the differential and the half shafts. Welded differentials do the same thing from the other end ! Regards from another Marcus
That plate is way too thin and running without the gearbox dowels is definitely causing the spline problems and wrecking the whole clutch, obviously way too much flex between the engine and gearbox, no wonder the spigot bearing is Knackered and input shaft has way too much twisting loads on the gearbox input shaft 😢

All good, and very methodically thought through Marcus..... lets hope your problems are sorted 👍
Happy birthday Geezer
Thank you Marcus for your sharing of this video. Cheers
Ah yeah, I'd definitely grab some MH hot wheels 🤔🤣
Glad you had a good birthday 👍

Would it work,if so would be a lot easier to shorten the slave cylinder push rod,to get some play
That's the easiest way and the most practical
Sounds like great customer service I’ve been thinking of getting one from there for a while now and now my mind is made up thanks for the recommendation
Happy belated Birthday Marcus, been following you for a while mate. Good Man!. Loving your Videos Pal. 😃 💯 👍

That is only for vauxhall engines.

Happy birthday digger fix all the things you said ya bi right mate.!

Best of luck Marcus
@marcus hayes thanks a lot for mention :)
happy birthday Marcus.
Happy belated birthday Marcus
I would be interested in buying them
Happy belated birthday mate
We always used a bit oak shaved down to spigot bearings diameter as a punch caused no damage and easy to get out. Happy Birthday and will you need a adapter fitting for zimmer frame.HaHa
Hello mate, massive fan of the channel, keep up the honest, funny and informative work😁 Can i ask, what year mazda rx8 did your box come from?
How did you overcome speedometer on the rx8 gearbox?
Really seems lots of hassle,why not go type 9,are there real benefits from using the Mazda gearbox
Why not just make the slave arm post adjustable and leave it? Take the current post out & drill and tap with a lock nut - assuming you don’t need to machine the casting to make clearance.
Happy birthday mate, welcome to the 38 club, two years and we both hit the 40 mark
Thanks mate! 👍 I didnt realise you were an old git like me! 😃

Im defo learning all the time mate! 👍
Always learning. Everyday something new. 💯

You have to turbo one of you escorts

Thanks for the advice mate! 👍 Iv actually got an input shaft that I use for a clutch alignment tool but I totally forgot when I filmed this video!
Happy birthday Marcus sorry for the lateness ....
Thanks mate! 👍
Happy birthday bud,all the best! Great work 👍
Happy Birthday mate! 👍😎
Thanks mate! 👍
You need a hybrid release bearing use the rx8 carier and a type 9 brearing ive just done it today
Do the hotwheels
7:30 RX8 Gearbox
Happy birthday to you
Thanks mate! 👍

Thanks for the advice and the birthday wishes mate! 👍 I'll have to do some research online and see how easy the input shaft is to replace.
@marcushayesford Any news about whether it is difficult to replace the input shaft bearing?
Check Haynes manual the Ford original ones fit exactly get the Ford bolts try burton power
Happy belated birthday 🎉🎉🎉
Thanks mate! 👍
Wishing you a very happy belated Birthday Marcus 🎶🎊

Definitely be interested in the hot wheels of Maude 👍 hit me up when they are available
Cool mate! 👍 I'll defo announce it heavily if I decide to have them made.
And a Hot Wheels Hiedi, that be nice! 🙌
Belated birthday Marcus
Thanks mate! 👍
if RX8 gear boxes are getting more rare, could you try rwd gearboxes from 350Z, S2000 or MX5?
Just buy a BGH semi helical. Rx8 box is a faff, heavy, too low a first gear and way more transmission loss due to larger gear drag.
Y don't you use bmw e36 gear box 328 one is bullet proof
The Mazda RX8 box is way strong enough for my application. 👍
Happy birthday you old git🎉
Thanks mate! 👍
Maude for me please , love that car
That plate is way too thin and running without the gearbox dowels is definitely causing the spline problems and wrecking the whole clutch, obviously way too much flex between the engine and gearbox, no wonder the spigot bearing is Knackered and input shaft has way too much twisting loads on the gearbox input shaft 😢
I have not been running without the dowels mate. The spigot bearing isn't knackered either. 🤔
Hi Marcus and your beautiful girlfriend Cat 🐈⬛, i really enjoy watching your videos, they are very entertaining and interesting 🤔 😊
Appy burfdee
The reason you killing clutch you drive like you stole it and being chased by police
7:10 the clickbait stops
Happy Birthday, mate!!
