Just found this thread http://www.theminifo... gasket__st__15
so its RTV for the diff housing to gearbox but gaskets for the side plates.....

[jameslearwood]

Simplest of things make you wonder about to put the block back on the box looking at the bolts not a clue which go where some longer than others and some have nuts others don't?
Might be able to figure it out just wondering if anyone knew to save time?

[jameslearwood]

All good figured out the bolts I have decided to think each stage through and plan in advance rather than attempting getting stuck, posting on here, then reattempting, to find out I've missed a bit and having to redo.
So tonight it's time to check primary gear and then attach the box to block need to order the countersunk bolts for timing chain and some others getting close

Right can anyone tell me what value i should be timing the cam too using the DTI and protractor i understnad the proceudre just not how i know what my TDC is for my cam, if that makes sense.

Also at what point should i install the fuel pump im just putting my mechanical one back in, i was going to do it after the oil pump but before i put the transmission on?

cheers

Which cam are you fitting? There is a good guide to cam figures on the interweb somewhere..or I could look it up in the yellow bible..

Here is that web page..

Just the standard cam out of the Rover 1993 rio 1275cc. Ooooohhh its in the yellow bible i have that, i think i will have a look.

cheers

[jameslearwood]

Shown Below is the OE 1275 A+ sprite/injection(50hp) cam.
It has 2 x 1/8" raised rings between lobes 7 & 8.


Checking height: 0.017" @ lobe

Timing: (Intake): 9/41 (Exhaust): 44/6

Nominal lobe lift: (Intake): 0.235" (Exhaust): 0.235"

Duration (Intake): 230 (Exhaust): 230

Lobe centre angle (Intake): 106 (Exhaust): 109

Lobe separation angle: 107.5

Lift on overlap: 0.025"

Accuracy: Very Good

Based on this photo i think this is the one

[jameslearwood]

So how do i get the timing from that info?

[jameslearwood]

Photos inside diff housing





Oil pump installed, is that hole uptop for oil flow? (block is upside down)


The rejoing of block and box

thin smear of hylomar under gasket and bead of RTV on half moon seal (dont worry the oil seal is on the transmission)







What a git that was to line up and tighten down but all done i didnt torque the nuts as there is no space for a socket, just went FT but not overtightened

Oh and the transfer float was 0.15mm as was the endfloat probably doesn't make sense but pretty confident its fine.

[AndyMiniMad.]

That cam wont need timed in with your DTI..Just set it dot to dot and it will be fine..If you really want to set the timing with the DTI then go for around 105 - 106deg ATDC...on number one inlet push rod..but you wont notice any difference than if it was set dot to dot.

Nice pictures!!

[jameslearwood]

Cheers Andy I may as well have a bash just to learn I an quite curious so how did you get 105-106?

[AndyMiniMad.]

Im going from memory here but I think thats the figures that are quoted in the bible..Im pretty sure the 107.5 figure is at the valve gear and you take a couple of deg off for timing at the push rod...Im not 100 per cent on that though.

[jameslearwood]

Right cheers Andy I'll have a read of the bible I want to learn this stuff so I have a better understanding it's all part of the fun hate not having the car but loving the project just wish I could work on it full time
