Lee's Garage

could you not have made a modified blank plate that incorporated the pipe? less weld to rely on.

as i understand it welding cast is a bugger.

my other idea is run the pipe through the blank plate and bung up the hole in the block where standard pipe joins?

[lee303]

its harder to make it all seal up to the inlet pipe and th eblock if its part of the plate though, adn the lip on the inlet to the block would probably mean you wouldnt be able to do it that way either tbh, its fine how it is, welding cast is easy with a good enough mig welder these days as they put alot less carbon into cast nowadays compared to years ago

[lee303]

so, having found out my gearbox is a hockley, and having it rejected by quaife, thought i'd just rebuild it myself!lmao
not a big deal, except for fifth gear, which had somehow seized so hard onto the shaft, it took me all day to remove it yesterday!
you need to remove it first before the gears will come out of the sandwich plate.
the box arrived back minus its selector assembly, that was in a bag with it, so, having sworn and faffed alot with the fifth gear, here's what we started with today

as you can see, quite a few bits! the main reason for the rebuild was the missing synchro lug on second gear, i have a spare box at the garage with nearly new synchro hubs on it, so stripped that to bits to get the spares, the started to strip the main shaft on my SCCR and ,made the best box out of the two, thats why there's two fifth gear selectors in the above pic, the one in my spares box had snapped at some point and been welded up, didnt use that one obviously!
this is the offending fifth gear, is quite a tight fit!

the gear set out of the plate, is held in with tow circlips, one normal and one external tagged

so, in the vices soft jaws and away we go!

got the pu;ller out and removed first gear, having previosuly removed a circlip

this is the broken bit on the first/second synchro, note missing lug

so, bit of fiddling, and a new one is in

then refitted first, and the bearing retaining circlip, and the bearing it retains

then get the newly painted sandwich plate

hold the gears all meshed up, then refit into plate, retaining with a cirlip on each shaft

now time to refit fifth! is one million times easier when you can heat it in isolation from the shaft

on she goes, then fit a circlip, and fit two thrust washer halves to the other shaft, and a wrap around roller bearing
thrust washer comes in two bits so it can be fitted into the groove on the shaft


now fit reverse gear and its selector, then first/second gear selector

then fit thrid/fourth selctor,fifth gear selector, and then fifth gear itself and its synchro runner

this goes in here to act as a fifth gear detent

then the gear and runner go on

then fit the reverse detent, stops you getting reverse when you dont want it!

then fit the roll pinsin the selector rods, you can assemble these 180 degrees out, but you'll soon know, as the box will be stuck in one gear or another! lmao

then finally time to fit the corss shaft and detents that hold the gears in once selected, the longer one goes in the thrid/forth gear shaft

refit end cover, then pop the lot back in the box, remebering to fi tthe fifth gear thrust washer on its shaft

i did it upside down so it wouldnt fall off the shaft either!

job done, just waiting for the turret to dry before i fit that too!


quite glad to get that all done after yesterdays saga i can tell you! should now have no crunching into second either! not as bad a job as it looks or sounds either, although if you have no previous experience i can see it being fairly dauntinglmao
Brian is edging closer to spraying, kurrust time at the mo!

[spanishfly]

nice work.

[lee303]

cheers

[OllyTB]

Good work matey, i really need to sort out a box for mine but i have so little patience know i couldn't get through a rebuild like you've just done without breaking something.

[lee303]

its not that bad tbh, as long as your methodical and keep everything in order, and having the right pullers etc is a big help, fifth gear was just a pain in the ass though!!

[Benn]

Very cool,
So its all good in the box now?

[lee303]

yup, all fixed

[The Simps]

that looked like a nightmare! If thats was me i would have had to of taken a million fotos so i new how things went back together! lol

[Benn]

yup, all fixed

Sweet, get that engine built.

that looked like a nightmare! If thats was me i would have had to of taken a million fotos so i new how things went back together! lol

You and me both...

[lee303]

its a good task to accomplish though, and really lets you see how your gearbox works, i love stuff like that

[Colonel K]

glad you know what goes on in that box!

[lee303]

well, it still worked when i finished and i didnt have any parts left over, so i think i dolmao

[LongLiveTheNova]

lol
Gearbox parts scare me lmao

Top job that

[CraigGreen]

I'd only do that with my G/box if I had a spare sat there to use if it went wrong.

I was thinking there were no gaskets either until last couple of shots showed the tube of sealant & the sealant oozing through the gaps.

Top write up as always Lee. Most people could use that as a rebuild guide tbh.

[rudd86]

I was thinking the same about the rebuild guide, a tad out of my league I thinks tho lmao
good work.

[lee303]

thanks guys, the wirte up in the old blue nova haynes manual is also very good, with many detailed photos

[CraigGreen]

But not in the Green manual NO?

Lost my Blue one years ago.

[lee303]

nah, it just says 'gearboxes are complicated, mkay' in the green onelmao

[novarallycar]

Those F10 sccr boxes were the bane of my life!! i could actually strip one with my eyes shut now! I had a hockley box and once i got used to stipping it you can do it without taking the detent plungers out, there is a particular rebuild order if you do that though. also my 5th gear was a lovely sliding fit onto the shaft , no puller required, shows the hockley quality control i guess.
looks good though Lee how close are you to having an engine to build? have you had any bother getting a hold of Mr Bowyer yet!

[lee303]

yeah, you have to force the detents back into the housing when you refit if you dont take them out though, and as it takes about 2 mins to remove i always do, as for the engine and mr bowyer, getting hold of him is easy, getting him to get back to you is a bit harder!lmao should have all the engine componets soon, then will measure up, send a few bits off for machining then assemble, want it in the car in february if poss

[lee303]

well, finally, after what seemed like months(oh wait, thats cos it was!! ) deemon tweeks finally pulled their finger out and got me my tapered ring compressor, anyone who wants one should go direct to summit racing imo
great bit of kit though


still waiting on bowyer, but it shouldnt be long now

[KeithRobinson]

Great work Lee

[lee303]

cheers keith, sorry about your problem, and i dont mean to go on, hope you get it sorted one way or t'other
