Suzuki Srad Fuel Tank Pump Flange Modifications

Suzuki Srad Fuel Tank Pump Flange Modifications

A typical fault with the Suzuki SRAD tank was the pump seal arrangement on the bottom of the tank.

If the pump and flange plate were removed for any reason and then refitted, there was a big chance that with a fraction excessive tightening of the clamp bolts that the spot welded flange would distort and then the sandwiched seal ring would not pull tight against the flared opening flange of the tank.

Major problem if you had done the above, filled the tank and had fuel pouring out the bottom of the tank on a nice hot engine / gearbox casing. Very poor design by Suzuki really.

Anyway, my customer having spent a good wedge of cash on getting his tank repainted was left in the same position the first time he put new fuel in his nice newly painted tank. Upon inspection it could be seen that the flange the clamp bolts thread into had distorted and hence the seal ring was not sealing against the tank flange lip.

1394333_10201812688990600_1496320034_n

As can be seen from the image above the original set up takes the form of a 4mm thick flange that is spot welded to the main tank in between the threaded bolt positions, you may also be able to see the dimples in the tank under the positions where the clamping bolts sit through the flange so the bolts dont actually damage the tank shell. You can also see the pressed up flange around the opening that the seal ring actually seals against when the whole thing is tightened up. Clearly also shown are the positions where the spot welds have been positioned in between the drilled and tapped holes.

1451558_10201812688110578_1319495453_nAbove image shows where I have had to drill out the spot welds in the original flange in order to get the damn thing off – best spot welds I have ever removed! This took a bit of tugging and hammering to get off and the next image shows that I then had to do a little panel beating with a small aluminium block to level the panel work back up a bit.

1488167_10201812686750544_1878547800_nA little bit of flushing off and a bit of sanding down and cleaning up and we are ready to fit the new flange.

1477649_10201812687190555_1337374619_n

Laser cut, mild steel, thicker 6mm pump mounting flange offered up in place on the original tank. This will be tacked and welded in  place using a 10mm thick top plate to help soak some heat away and to help stop the new flange from distorting whilst welding.

1st we need to drill and tap out the holes. Drill out 5mm (4.8mm actually) diameter in order to tap M6. I did this using a battery drill set at low torque setting to prevent breaking the tap off in the hole. Notice that I didnt get the holes laser cut as this leaves a “hard” surface on the material which is a nightmare to thread out then, so all I did was get the laser to put a cross mark exactly where the holes come, ensuring dead accurate marking.

1461168_10201812687470562_548027505_nOnce all the holes were drilled and tapped out, a double check on the orientation and bolt the blanking flange up, sett up on the tank for accurate tack up.

1465371_10201812685430511_1213561555_nOnce tacked up, I removed the blanking plate and double checked the tack up and positioning. I had to make sure that I clamped the tank panel work tight up to the flange. Unfortunately even with the new flange tacked tight up I still had a gap to fill where the original dimples in the tank are, so I had to weld as cool as possible but a large fillet size to cover the dimples.

601593_10201812684590490_1838420620_nOnce the weld had had time to cool down I removed the blanking plate, although the flange had stayed flat and level there was a bit of shrinkage in the panel work.

The blanking plate was the used as a template to make a silicon rubber seal for testing, I also had to drill the blank plate and weld 2 pipe stubs on so that I could connect an airline and pressure blow off valve.

The seal and clamping plate were bolted back in place and tightened up I connected an airline one side and a pressure relief blow off valve the other. Spraying soapy water around the welded area and then pressuring up the tank if there is a leak you can see air bubbles bubbling out of pinholes etc.

On to dry off, clean up, bit of paint and jobs a good un!

Just waiting for the laser cut nitrile seal to clamp up and finish the job.

Ducati Oil Catch Tank

Ducati Oil Catch Tank

A nice little fabricated aluminium oil catch tank to fit up behind the head stock and between frame spars on a customers special build Ducati motorcycle.

Initially a simple card mock up was made and changed several times just to get the tank to sit tight up and at the right angle to the frame miss all parts required.

995201_614518405260671_1390513078_n

Once the mock up was complete and we was happy with it, I cut out and pressed up the tank in 2 sections of 1.5mm ns4 aluminium.

Just to make sure I tacked the tank up and we tried it in position to ensure it wasnt going to catch anything as it is maneuvered into place. Once held in position we could see what actual room we had available to us and where we could put breather, site glass, filler cap (to empty in this case), and of course the mounting points. Very little room was left and we decided to mount the tank on welded brackets to each side frame spar, this also then needed thought to be able to bolt the tank in position. The best idea we came up with was to machine top hat, blind threaded bosses to weld into the bottom of the tank. Shown below.

1382397_614518408594004_1194232634_n (1)

Now the mounting top hats are welded in we can see that there is very little room for the breather and inlet pipe, made from 6mm aluminium tube with a 1mm wall thickness.

67062_10201573501611065_1449171905_nSo above you can see that the bottom of the tank is quite “busy”, the pipes had to be welded into the bottom of the tank as there was no room above or down the sides of the tank to run flexible hoses.

1380439_10201573500891047_1419960809_nSo if we look at the other fittings on the tank you can see the black filler bung is on the top, the sight gauge is mounted half way down the tank (black with clear lens) and if the oil mist ever fills enough you will see oil in the tank.

Both of these fittings had a simple little machined threaded boss with a “flange” round the top. My customer actually provided the machined fittings, only the filler threaded fitting had very little top flange to weld to. This with aluminium can be a problem as unless we have a flange with a little “meat” on it will rapidly be saturated in heat and “blow” away before we fuse to the main tank.

Aluminium dissipates heat very quickly unlike stainless steel or mild steel, but as this tank was so small and thin it quickly became “heat saturated” and you really have to watch the heat input otherwise the weld will “flood out” and look poor as well as being uneven and have massive excess penetration into the tank.

249077_614518415260670_1364078305_nAbove you can see how small the flange was on the filler boss, only approx 2mm in section.

67062_10201573501611065_1449171905_nSo once complete and welded up the tank needed to be tested for leaks, a simple process whereby we block all the holes up, add air pressure into the tank and simply brush soapy water around all the joints and welds. If there are any pin holes then the air will bubble through. Luckily this had no such issue.

14138_10201573502131078_872299244_n

Above you can see the finished article and the basic drawing we worked to.

Now the tank is complete my customer is taking the whole bike to Italy to a specialist frame builder to have a frame built.

Making Simple brackets for motorcycle exhaust mounting

Making a simple stainless steel Bracket / Mounting plate.

20131020_130318 20131020_130447 20131020_130502 20131020_130721 20131020_13104320131020_132531

The selection of images above from left to right show simple steps in making a pair of stainless steel exhaust

mounting brackets. The stainless steel brackets have been hand cut from 3mm thick 304 stainless steel sheet.

I have used a 0.8mm thick cutting disc in a 115mm grinder to slice through the stainless. These are purposely for stainless steel material and slice through it like butter. You do have to be very careful though as any sideways movement will shatter the disc.

A cardboard template had been posted to me, I had simply marked around the template with marker pen, used a centre punch to dot the hole centres and then once happy with the rough cut out I clamped the 2 plates together in the vice jaws (protected with masking tape to prevent marking the metal). Once clamped together I sanded all the way around the metal plates to ensure that an even size and both plates were to marking out.

Once happy with the size and finish of the plates I used 3 different drill bits for drilling through the plates whilst back to back in the vice jaws.  Now an important thing to remember is to always use a good quality drill bit that has been sharpened correctly – do not drill at a really fast speed setting otherwise you will burn the drill bit out.

To make life easier I have used a 3mm, a 5mm and an 8.5mm drill bit. Pilot drill, intermediate drill and a finished size drill bit. If you can remember to drill holes in stainless steel using a similar process you stand a lot better chance of drilling an accurate hole without burning out drill bits and putting heat marks in the stainless.

Once drilled through the correct size of 8.5mm diameter (clearance for an 8mm bolt) I used a small countersink tool (at a slow speed) to debur the holes.

To complete the job I used a coarse Garry Block to clean and put a light grain in the plates.

A quick check against the template proved the mounting plates to be accurate and therefore ready for packaging and dispatch.

Dodgy Mock up of the tank (below), done to ensure that we could actually get the tank between the frame spars and fitted onto the rubber lug mounting points.

20131005_200103

I now have to make a finished item from new aluminium, c/w all the holes and fittings and pipe work.

No mean feet in 1.5mm thick  alloy, heat dissipation / excessive heat build up will be a problem I will have to overcome, otherwise I will have some very uneven weld profiles.

There you go then now to actually make the thing proper like !

Blog to follow will detail the build of the Ducati Oil Tank

Ducati Wheel Speed Sensor Bracket

I have recently been asked to manufacture 1 off replacement Ducati wheel speed sensor bracket.

The original one was manufactured as 2 separate pieces and then welded together. This had been knocked and bent.

I managed to straighten this out, nick through the existing weld and re-weld around 3 sides to”repair” the original.

Knowing that this original design may have a weakness where the joint between the 2 parts are only able to be welded on 3 sides, I machined the item as a single part, using a manual lathe and mill.

The material I used was HE30 Aluminium, or  what is now commonly known as “6082 grade alloy” or “T6″.

Particulars of this grade of material is ideal for this application – “Alloy 6082 is a medium strength alloy with excellent corrosion resistance. Alloy 6082 has the highest strength of the 6000 series alloy. Due to the higher strength of Alloy 6082 it has replaced Alloy 6061 in many applications. Alloy 6082 is typically used in highly stressed applications, Trusses, Bridges, Cranes, Transport applications, Ore Skips, Beer Barrels, Milk churns”. (taken from http://www.aircraftmaterials.com/data/aluminium/6082.html 30/9/2013).

A more typical application for this grade is aircraft parts, billet alloy slab yokes, fork clamps, handlebar risers.

Above image shows 1 piece sensor bracket, machined from billet T6 Alloy, etch primed and painted silver

Formula Ford Fuel Tank Modification

I made this fuel tank in aluminium for the local Further Education College when they started a Motorsports course. One of the first cars they purchased for race and testing was a formula ford with 1600cc engine.

The race car itself had been stripped down and various improvements made to it to improve all aspects of the car by students and lecturers .

Original tank with new sender flange hole cut in

The fuel tank itself was originally made with fuel pickup  fuel filler neck and breather and foam filled, no facility had been required for a sender unit. Upon strip and rebuild it was decided this year that they wanted to upgrade the tank to include a fuel level sender.

Sender unit & machined flange

A new sender unit was sourced and a new alloy flange to mount the sender was machined and collected with the tank for mods and fitting.

Now with a tank that has been foam filled to prevent fuel slosh is not as easy to modify as a tank with baffles. Typically you can never get all of the foam out of the tank. As this foam has been soaked in fuel it is very difficult to prevent ignition of the fuel vapours when electric arc welding.

CAUTION !!  – DO NOT TRY THIS AT HOME

So to modify this tank I needed to mark and hole saw the new aperture for the new fuel sender mounting flange, upside down to any swarf falls out and not into the tank. I cannot just start welding – I had to fill the tank with an inert gas (argon) to remove all the oxygen in the tank.

Filling with argon gas

Argon – an “inert” gas

Argon gas is an inert gas (non-reactive) and is also heavier than air. I f we completely fill the tank with argon gas – even if there is still tank foam and fuel vapours in it the fuel vapours will not explode. I would not recommend anyone try this at home as it can be dangerous and I have seen a tank “blow” and send the welder across the workshop (he was lucky not to be hurt) and the tank ended up ripped apart due to the explosion when the fuel vapours ignited.

Fuel tank foam clearly visible through new hole

 I could not remove all of the foam and hence filling the tank with argon. I prefer to completely empty the tank, wask it out / steam clean it inside and then fill with argon before welding new fittings to a used tank.

Having had experience of welding aluminium tanks that have been used I know that I can get away with filling foam filled ones with argon before attempting welding of new fittings etc.

tacked up sender flange

See above the sender flange in position tacked up and level in the tank, note also the argon gas is still being fed into the tank by the black hose. Please also note that the bottom hose stub (fuel take off stub) has been taped up to prevent heavier argon gas escaping from the bottom of the tank.

New Flange welded in position

New flange welded into position, once this has cooled down its ready for blanking off and pressure testing again just to make sure that there are no pinholes in the weld and potential leaks.

If it is leak free then we need to fit the sender and squash the foam blocks and push back into the tank through the filler neck.

Fit the sender 1st and then push foam back in thro filler neck

AGAIN I NEED TO REITERATE – PLEASE DO NOT ATTEMPT THIS AT HOME !!

Hopefully the college will be happy – and now they can see how much fuel is in the car without using a stick.

Hope the students take care of it and plumb back in neatly :)
