Ahh yes there is nothing like opening boxes full of new shiny bits...

Countersunk screws in timing plate..



Modifications to the inside of the timing cover to accept a duplex chain..There is a small lump that needs to be hammered flat aswell as removing the metal behind the breather hole.



I always cut the breather down a bit to clear the fan...most people just bash it flat with a hammer...either way works but i think this looks better..





Sorry to be filling your thread with pictures....let me know if you want links instead..

[jameslearwood]

Right thats great cheers andy
no worries on pictures knowledge should be shared

was going to do that to the breather saw it in your project good idea and it needs a clean out.

is that the inside of the timing cover after mods or before?

to get the lot balenced you send the crank with flywheel and clutch plate off to a machine shop and ask them to balance it. its not to expensive and is definatly worth it! and to balance the rods you could also send them off the the machine shop and ask them to balance them but i dont know how much roughly it would cost.

to do it yourself get a set of good, accurate scales and weigh them. then make them all weigh the same as the lightest one, but making sure you are not touching the bearing faces or anywhere near that are. just where the rough cast is.

[AndyMiniMad.]

Thats an after picture...Im looking forward to seeing your engine coming together...I love all this engine building malarky..

[jameslearwood]

I see clubman so its just about chipping away at rough casting to get the same weights might ask the engineer what he would charge.

Cheers Andy. I've got this bug now totally love the engine building wish i had unlimited funds and could go crazy

[jameslearwood]

So that is the engine ready for collection and my bank balance £350 lighter.

That cost is for: camshaft bearings, full set of crank and piston bearings, head skimmed, bores polished up, piston rings and crank polished. that is including VAT and some carriage cost on some parts.

you reckon thats reasonable?

Think i need a better paid job to fund this habit

[jameslearwood]

So its been a week b'jesus.
here is the shiny bits from mini spares



little bit of superficial damage on rad bit dissappointing but totally forgot to chase up and it will clean up easily enough.

[jameslearwood]

engine returns from the engineer






Nice and shiny bit dissappointed it was cleaned down afterwards but hey ho edges of head are quite sharp should i smooth down a bit or leave alone

[jameslearwood]

valves lapped in exhaust are nice but the inlets all have a flecked look should i sand down a bit then relap?



red oxide primed block (2coats) head is drying now



I am going to paint block blue and the head yellow, going to paint the master clutch cyclinder too

[AndyMiniMad.]

Just keep lapping the inlets untill they are the same as the exhaust...Course paste first, then fine paste..should only take two minutes per valve.. Head looks great..I love freshly machined parts..

[PhilipGCaldwell]

wooohoo, nice stuff, must of hit your pocket this little lot, the head crank and block look excellent

like Andy says, course paste first working down to fine for a nice finish and thus a good seal so

[jameslearwood]

Righto will go back to using the coarse first cheers thought I had missed something out
Aye it's made a massive pit in the finances lucky I don't have too much overheads still dossing at my folks place just be glad when it's on the road can't wait to start assembling.
Still need to get the clutch Plate, and look into upgrading timing chain and flywheel then hopefully I get paid enough to cover mot and tax

[grahama]

Engineering work looking nice indeed, had some done myself but not as much as you. I too like the look of.freshly machined engines, just degraded the cylinders on mime and keep looking and feeling them. Help me please !!!

Seriously tho, keep it up, enjoying the thread.

Graham

[jameslearwood]

Hahaha Graham that is a bit worrying but we all like to stroke it now and again shiny engine bits that is. Hoping tO finish paintwork tonight then assembly

[jameslearwood]

Interesting one ordered my new clutch plate, lightweight flywheel and duplex timing chain set (went with standard instead of adjustable), in process i measured the clutch plate diameter to double check lone behold only 175mm so guessing someone has installed a 180mm one at somepoint instead of a 190mm could job i am replacing it.
