Sprint Unobtainium and TR5 Refurbish Parts

After a few weekends away and Stoneleigh last weekend I am hoping to do a little work on the cars this weekend.

Anyway I managed to get some more unobtainium parts for the Sprint engine rebuild

4 NOS rocker arms - I need the other 4, but I do have an unmarked set of secondhand ones to complete the head

I also got a NOS jackshaft sprocket

and a NOS  roller bearing for the nose of the gearbox input shaft - this sits in the crank

As to the TR5 I eventually got the accelerator pedal assembley replated, this has sat on  my desk at work for the past 7 years !

The soft top handles have also been rechromed

and I got the door latches replated

The seat frames have gone off for blasting and powder coating too, so two days spannering ahead

More Sprint Goodies

No actual work on the cars last week as I have been away in Liverpool working on Top Gear, and this week I am going to Newcastle for a repeat of the same, but some more nice Sprint parts arrived in my absence

Nice steel flywheel - I have the ring gear for this, just need to "borrow" the oven one day when Anne is out to heat the ring gear so it expands and can be dropped onto the flywheel

Light weight clutch

Some NOS terry Valve springs

and a NOS timing chain

That's all for now, cannot wait to get back to some spannering !

A little more TR5 progress

This weekend I have been working so not much time for classics, but I did get a few little jobs complete on the TR

It now has a handbrake and its tunnel cover

and I got the inner wing splash guards fitted and the plenum drain pipes.

The TRs have that crappy arrangement where the plenum drains come out between the inner wing and the wing, so guaranteeing rust on top of the inner sill and the wings at the bottom, so I have extended the drain hoses and brought them out through the splash guard, as you can see, but with a nice 90 degree bend at the end of the hose to prevent water and air going the wrong way.

Thats it for today, however I have heard that some more nice engine parts for the Sprint are ready and on their way to me .....

Sprint Bits and TR5

My JE forged pistons arrived on Friday

These are 160 grams lighter (inc rings and pin) than the standard piston, so each rod and piston assembly is 340 grams lighter than standard :) - I hope this will help the engine rev a little better - I need to decide on a cam now.


I have spent the rest of the day on the 5, I completed the rear boot wiring to the lamps

Then I finished the B post and strengthener trim in the door frame

the next job was to install the finishing strips to the wing seams - I hadn't looked forward to this as the painters had used seam sealer between the panels, so after undoing the fixings, I had to gently cut through the sealer with a stanley knife (without causing paint damage) before I could open up the flange and insert the trim strips.

These will need painting body colour, but I will do this when the car is complete so any other paint damage (although I am hoping there will be none) can be rectified at the same time.

TR5 and Sprint EFI

I had a nice package in the post today from Jenvey, but before we get to that, I have resolved to finish the 5, so I spent the weekend working on it.

Windscreen, wiper arms / blades and interior mirror now fitted

Door mechanisms, window winders and glass now fitted and all working

Interior Dynamat fitted, and a start made to the inner rear wheel arch foams and trim

Steering completed

Wing and door trims and front sidelamps fitted

I'm on a roll with this, and intend to keep going .....

But back to the Sprint, inside the box from Jenvey was this

throttle cable, fuel rail, and linkages

idle air bleed kit - this replaces the idle bleed screws so you can control idle with a control valve driven from the microsquirt - the valve didn't come from Jenvey - its a vauxhall one

and finally a pair of twin throttle bodies

45mm chokes, so sexy in fact that I couldn't resist seeing what they looked like on the manifold

 
I know they are not in the correct placement - the linkages should be on the inside but who cares ? I need bell mouths but I want to see what room I have left between the bodies and the inner wing before ordering these.

Looks like I am going to be very busy with the 5 and the Sprint for a month or two

EFI Crank Position Sensor

The original fan carrier mounting holes in the timing cover are "blind" so I needed to make up a template, to mark and drill the holes in the sensor mounting bracket

The position of the holes was then transferred from the template to the mounting bracket that I had purchased

I then made lateral slots in the bracket, so the position of the sensor can be changed in relation to the teeth on the trigger wheel, so that the edis can be set to fire (in limp mode) at 10 Deg BTDC. I also cut the front of the bracket downm as it projected beyond the front of the crank pulley

The remaining issue is the timing mark, so I made a small bracket on which I will mark TDC, and 10 BTDC for set up, but I cannot finalise this until I find TDC on the actual engine (I need a timing wheel, and a piston stop which I will fabricate from a spark plug and a bolt.

I had hoped to get this fitted to the car today, but time was against me, so thats for next weekend

Trigger Wheel and EDIS

More progress on the EFI. I had only been able to source EDIS connectors with wiring tails fitted, this means that to make connections you need to join cables with solder and heat sleeve. i don't like this because of reliability and neatness issues, so I stripped the edis connector

and removed the pins, so I could strip them back and recrimp them

Here's it all done - the bare wires are the trigger sensor and edis pip and saw shield wires, that go round the signal cables - these will be hidden when the loom is wrapped, just like Fords and other manufacturers do

I also had time to make up the coil pack ends of the HT cables - the plastic "hats" on the cable ends retain the cables in the coil in addition to the normal press fit connectors - these will NOT fall off or come loose.

I got the trigger wheel mounted to the crank pulley too

The "teeth" are spaced nicely from the V belt pulley

So time to check it all fits on the timing cover

Just got to mount the sensor now, I will mark the bolt holes out, but then cut slots so I can adjust the timing, I also need to notch the bracket where it is a little close to the middle timing cover bolt
