Epic work, Alex! Shame about the box

Alex, just took a screen shot of your engine - for two reasons, (a) I love the colour scheme and may use it and (b) I was about to start a thread to get some help with a Speed problem and the part I need is clearly shown on your engine

Cheers mate, what was the problem you had?

 

I've got 4 weekend to get it all done and back up and running and hope that it doesn't slip out of fourth gear ready for Beaulieu... 

 

 

Speedo not working which is preventing me getting the MOT done. Cable snapped at speedo so I changed it, but cable is not spinning, maybe not fitted in properly at the Gearbox end? 

I'd like to go to Beaulie again but we will have to see.

Hope you get the Gearbox sorted

Ah right that's annoying, it is a bit of a fiddly job when everything in.

Might see you there again then.

Hi Alex the car is looking very good!
What did AC do to the engine regarding needle and timing?

Cheers Andy.

Cheers.

 

He checked that the timing was correct, it was spot on 10 degrees at 900 rpm and fully advanced was 30 degrees across the rev range as AC Dodd has re-curved my Dizzy for me, it was 17 degrees from factory and he set it to 10.5 degrees. He used a lambda sensor in the exhaust so that he could tell if it's running lean or rich. Mine was very lean as I had a lean needle fitted for running it in. He then polishes the needle diameter to let more fuel through, fits it and then rechecks until the mixture is correct across the rev range. He also checks the carb piston drop and puts in the correct dash pot oil to suit the carb, mine had automatic transmission fluid to get the correct response, My 998 that was in the car previously had 10w40 when AC Dodd tuned it 2 years ago.

Good news - Speedo fixed, had to disconnect the top plate where the speedo connects to the gearbox to get the round speedo threaded cap on.

Bad news - son's future inlaws have planned to visit us same weekend as Beaulieu - oh well IMM it is then

[andyt]

Thanks Alex, what needle do you have in yours? i too have had my dizzy re curved by AC but i have been struggling to set the mixture anywhere near correct i have a BCE needle at the moment but may try a BDL which i have.

AC lives in Salisbury which isn't to far from me and i was wondering if he did individual tuning?

I had a BDL in mine but then AC took (I think) 0.25mm off the diameter. Looking on minty lamb BCE is very slightly smaller diameter and richer than the BDL. 

Have a look on minty lamb here ---> http://www.mintylamb.co.uk/suneedle/

 

He did say he would do individual tuning, or if you could get together a few others then it would work out cheaper. Send him a PM. Just make sure everything is in good condition such as the spark plugs and most importantly the carb, if it's unknown then may be worth rebuilding before hand.

[andyt]

Thanks Alex, I'll PM him and see what he says, carb was rebuilt with su kit including spindle bushes and seals.

So last weekend the engine came back out, gearbox off and stripped down. Before stripping it I checked the position where it went into gear and took another gearbox off a 1275 and compared it, both were pretty much the same just the synchro hub didn't cover the 4th gear on the 1293 as much as the 1275 so something was wrong. Unfortunately most parts from the 1275 G/Box was scrap as well as the casing unless I machine it.

 

1st problem was the moly surface was no more.

 

2nd problem was the Idler gear shat it self causing a bit of damage

 

I made a tool for removing the first motion bearing so I didn't damage it.

 

also made a 1st motion shaft puller.

 

I ended up changing a few bits on the G/box, first was the 1st motion/4th gear as slipping out of gear caused damage to the little teeth, I out of the 6 gearboxes I've stripped I had one usable one . The next thing was the selector levers, they had a lot of slack in them, I could move it up and down quite a bit, measuring the height of the pivot bush and then the lever assembly there was 0.45mm difference, measuring another one there was 0.25mm so swapped parts around to get about 0.1mm of difference between them. I then had to change my brand new selector fork, holding the G/box in 4th seems to have worn it quite a bit, luckily I had a good spare. Also a the reverse gear wasn't very pointy so found a better one.

 

 

It's all back together now and ready to be fitted to the engine, I've got an oil leak from the timing cover but need to get a new gasket that's 0.7mm thick rather than 0.4mm which I have about 7 of .

 

 

 

The cardboard box with all the gears in at the bottom of the photo is all scrap , 5 X 1st motion shafts, 5 X reverse gears and loads of 1st, 2nd and 3rd gears.

 

 

 

[alex-95]

So the engine went back together

 

 

Back in the car and took it for a test drive, Fortunately it doesn't slip out of fourth gear anymore, unfortunately it crunches into second I thought I fitted a better baulkring but maybe not, Either that or the selector levers are too tight?

 

 

Had to get the wheels re-tracked, which was a pain as no-one local had gauges to fit 10's anymore.

 

Drove it around a bit.

 

Then made the trip up to Beaulieu mini cooper day last sunday, The mini went very well apart from the 2nd gear crunch and the temperature rising quite quickly when stuck in traffic so I'll fit an electric fan.

Absolutely stunning mate

[andyt]

Did you stop off at Sammie Millers Museum too? I also went to Beaulieu it was very good as usual, i did see you Alex with the bonnet up just as i was leaving! 

It must be quite a trip from Cornwall, very nice car a real credit to you.

Yeah drove up on saturday. Yeah was a good show again, bit of a rubbish layout IMO. Oh right, I must have been at the car as I didn't leave the bonnet open unattended  I didn't spot yours.

 

Yeah about 3 1/2 to 4 hours but wasn't that bad. I got back about 8.15 and my ears were still ringing from the noise at 11 o'clock  .  Cheers

The weekend after the last post the engine bay looked like this ... Again. Driving it was just going to damage 2nd gear so took it out.

 

 

Then the next weekend I rebuilt the gearbox again, fixed a silly mistake with the help of mokespider and refitted the engine.

 

I made some brackets to bolt an electric fan to the inner wing to aid cooling when sitting in traffic ... hopefully ... still need to try it out, it doesn't seem to stop any flow from the mechanical fan.

 

I had to re-route my fresh air vent for the passenger side, With the van grille on you can't have the standard saloon air intake so I made my own that goes under the front valance.

 

Oh and drove it, all the gears are good now, just need to sort out the vibrations when going around 70mph
