Can i make this mod to my chassis.

[LeonN]

first please let me say sorry for my awful little pic. i am not good with computer drawing relay. it might show.

i have swung my engine into the chassis today and the sump if fowling on the bottom rail of my engine bay. my book is not with me but it is the opposing rail to BR9. i was hoping to weld in another tube and cut the first out as in pic A apposed to pic B witch is standard. marrying it in with the chassis platte under the suspension mount and the engine mount. much like the way i have seen people rase the top of the bulkhead for taller gearboxes.

is this safe and does it make sense?

Hi Leon,
not totally sure i understand which tube you need to alter ?

which tube would you alter?

cheers

thanks andy. 42 people it took before you point out i am not making sense.

hear is a pic of my bottom rails. i have added an arrow at the rail that needs a chop.



the pic in the first post is that section viewed from above.

hope it helps.

Hi Leon,
wasn,t a case of you not making sense mate, i just needed to know for sure which tube is causing you a problem before offering my opinion

I,m not a structural engineer but that rail BR8 is in my opinion a very important part of the chassis as it creates the triangulated strength to the front of the chassis.......look where it joins the BR1 tube at the front end.... right upon the area that holds the suspension mounts.

If at all possible i would suggest at altering the sump to fit the chassis rather than changing the chassis to fit the sump, can you do that?

Or make engine mounts to raise the height of the engine , it must only be a matter of a few mm ??
if doing this creates a problem above the engine for the bonnet then i,d rather raise the bonnet than alter the chassis.

Sorry if this is not what you hope to hear,

cheers

that is fare enough. unfortunately the sump hits the side of the rail rather than the top. so i need to take a bit of the bottom of my sump and some off the side. keeping the volume in the sump is going to be a bit tuff but if it must be worked out then work it out i will.

tar man.

I must agree with Andy.
Not sure why your sump should foul the rail.

But it would not be a good idea to cut this rail.
If you have no option then I would put a full length tube beside it,
back to the bulkhead tube

you can do what you want but you will need to box it in with 3mm plate top and botom to get the strength back. what engine is it and what part is going to foul? do you have any pictures as i find it hard to see

[LeonN]

m42 engion. i will go take a pic now

[LeonN]

ok so hear is a pic of the problem. not the best but was hard to get an angel that made any sense.



the sump you can see is hitting the rail and the engine still needs to go about 8mm to the right.

i dont know about tacking width out of the sump as well as tacking a little off the bottom. if i need to keep the volume the same then i will need to weld a box on the other side of the sump.

[HandyAndy]

what about raising the engine so it clears the bottom rail?
you could always put a nice bonnet bulge in the bonnet to increase the clearance needed above the engine??

cheers
