Hi again I have an oil bath filter which I understand is a better bet than the pancake filter that I have fitted. Why is that BTW - what improvement should I get? Anyway, here it is with various tube connections and clip and a valve in the intake nozzle. I don't know if I need any other parts/connection hose? So how do I fit this and connect it properly to my engine?.. How, in particular is the oil bath case supported in the engine bay - see those clips on the bottom? Thanks
You need the round tray bit in the corner behind the battery , the filter sits on that and clips hold it on .
As above, the b.eige thing is the stand/support for the oil bath filter, which someone's chopped off in the past. The other bit is the breast tin that goes behind your crank pulley.
Much bigger filter area and better at stopping bits getting through (although the paper elements are even better) and most importantly pre heating of the incoming air helps stop carburettor icing, makes driving in cold conditions much better, lastly somewhere for the fuel tank to vent into helps with fuel vapour smells.
Thanks. Ah, I can see that that tin-wear is the pulley cover. That one is a spare I inherited with my bus See this better piccy of the filter tray. It has a bracket (factory by the looks) with holes drilled. Does not look as if it was the original as there is no trace of where a previous bracket fitted. It looks as if I could bolt it on using the seam in front of my battery and the engine bay floor. Regarding the filter pipework, I can see where the crankcase breather attaches to the filter housing but there is no-where obvious for the tank vent pipework (currently feeding into the top of my pancake). Also, the inlet trumpet valve has nothing to attach to it to actuate it (a thermostat?) and there is no hole in my floor for the hot air inlet pipe to feed through. Is this heating arrangement bit essential as I don't have it at the moment... Thanks all again
Should be able to bolt your stand back on. Failing that, just plug-weld it on. As @Bigherb says, the original will give you somewhere to connect all your breathers and will prevent manifold icing/chilling. There is a famous pic of all the air filter connections - sure someone will post it.
It looks like an prototype bay single port engine filter. The pre heat flap is just controlled by the airflow, the balance weight keeps it closed a low engine speeds the more airflow the more the flap opens. prototype bay tanks had a different tank vent, you will need to drill the side of the of the filter and attach a spigot for the tank vent. Find the correct rear tinware with the hole for the preheater pipe or cut a hole and find the correct pickup pipe too the cylinder head..
Thanks for that. Could you indicate where to drill the hole for the tank vent spigot? In the lower part (which holds the oil) or the upper part (which hold the coir filter)? Hopefully the lower! Assuming that I do not drill the bottom tin or replace, is there going to be a problem not using the warm air feature - because I don't have it at the moment! Ta muchly
Right, FFS this is blowing my mind T-piece to C, seems to be the lower pan - correct? So I need to drill my hole and connect spigot here? (see question above) A-E and B-funny - I have no concept of or sight of any connections on my filter top, or anything... Not even looked at that sneaky H pipe... My G-F pipe - Karma And I don't have a funny round thing I have a 1inch tube - see my original photo.
That is the late Bay filter. The funny round thing is a vacuum diaphragm for the pre heater hence the hoses to the top of the filter which is a thermostat. You only need to connect the engine breather pipe and the tank breather pipe in the place shown basically in the bottom part of the oil filter above the oil level making sure it doesn't foul the top part if the filter when refitted. The very prototype bay filters used a smaller diameter preheat hose.
No need to drill any holes , you might be missing rubber connecting tube on filter . That pic is not very clear on the actualcomponents . Have you got a Haynes ?
