GLE220J - 1970 18/85.

Forged Omega pistons

Can't afford to eat anymore having now paid the engineers and James says you can only have a go if you are a very good penguin. 

Can you spot the subtle difference between the original and rebuilt head. 

Much swearing and bruised knuckles has seen the engine beaten back into place.

It has fought all the way. First it was stuck between the slam panel and servo. Then it got stuck on the displaces tube. After that it the cross member would not locate and as a final fight the drive shafts would not locate. 

After a threat from a big bar and a hammer it finally behaved and stayed where it should be.

Looking really very good. Getting excited yet?

It's in. All the bits are bolted on. Oil cooler plumbed in and fixed in place. 
Got exited. Turned the key. Nothing happened.   I suppose I should have known better than it start and behave it's self straight away. 
After some fettling it was tried again and it's not gong to run properly. 

Plugs out out and put on the Arger to warm through. 
Engine turned over to lubricate and prime everything. 
Hot air gun down the plug holes to warm things through 
Plugs back in. Turn key and the beast comes to life. (Sort of)


It's running but the fan is catching the shroud and the water pump seems to have developed a nasty noise. 

I've done a carb rebuild, though I donno if I did the best of jobs, to be honest.

I ordered a kit from SU/Burlen. Had a bit of trouble as my carb had the waxstat on the jet, which they no longer make (they're not very good to begin with, apparently), So I had to order a new jet, but otherwise I think it went ok.

One of the tricky parts is centering the needle into the jet.

I rebuilt a HS6 for a Volvo a few months ago. Other than the linkages, virtually identical to the Mk1/11 Crab.

I found a few short videos from Moss quite informative as it's been a few years since I rebuilt a SU from scratch.

Jet replacement

Float adjustment

Float issues

My observations:

(i) It can be a little tricky to seat the O ring correctly in the float chamber when replacing the jet (see video).
(ii) On my carb the jet locking nut would not undo without risk of damage. A few hours in the freezer followed by hot water and a few nights soaking in penetrating oil and it freed up.
(iii) I found that oiling the thread of the jet locking nut allowed the needle to be centred easily as you need to tighten it just enough to allow centring then tighten.
(iv) The nylon tube connecting the jet to the float had hardened and split and this can be a cause of leaks as it flexes as you use the choke.
(v) There was a surprsing amount of wear on the float needle tip given the fact that the carb had apparently only been used for very few years as borne out by the overall condition. This can lead to flooding.

All parts available from Burlen


Hope this helps
