LCB Manifolds etc,
Discussion
Hi, still here, lurked a bit but busy with wedding, new job, new house etc...
Anyway, between trying to work out how I am going to get an imovable object (mini) 330 mile north of here to new home, I have got the following question.
The new LCB manifold flanges are thinner than the carb flanges..... when you tighten up the nuts (ooh er missus) the washer obviously twists and tightens on the carb manifold most. Any thoughts?
Also, supplied with the manifold was a bracket that clamps around the down pipe and fixes to summit. Top bolt of the diff?? Cannot work that one out?
Finally, and I know its been asked before, a 44HIF has loads of pipe connections, bottom ones obviously fuel ( i think) the others are presumably vacuum connections are they?
Think the aerosol fumes have gone to my head,

There's a PHer offering a trailer service in the south east IIRC if that's any help - can't remember his name, will do a search. It's Melv

Had this prob myself - would be interested in the answer, no idea though.

Bolts to the gearbox steady IIRC - at the start of the central tunnel just below the bulkhead.

The LCB problem is very common, alloy inlet manifolds nearly always have flanges that are thicker than the steel exhaust flanges.
The workarounds are:
1) File the inlet flanges down. Takes a fair while to do this, and if you have to make them much thinner it may compromise the strength of the flange.
2) Make a stepped washer. I did this by cutting a washer in half and tack welding it to a complete washer. If you can source some very thick washers you could also file/grind down one half of them.
3) As above, but weld the "half a washer" directly to the LCB flanges. File/angle grind to the desired depth.

I had the manifold problem on a budget lcb - the Janspeed one is ok - tried the stepped washer route but got fed up with losing them and getting them on round the right way all the time.
Plan B was to find some small strips of the correct thickness sheet and tack weld each end to top/btm of the manifold flanges...then filed out the stud hole.
Job done....permanently !
