Bits n pieces for Apollo Tank fitment

[AndrewE]

Need some help to identify some bits for Apollo Tank set up (K series)

Can anyone advise part number / spec for following

1. Magnetic Drain Plug

2. Fittings for cam-cover end of breather hose

3. Breather hose to cam cover (just the hose not the fittings)

 

thanks

Andrew

Andrew,

from memory the drain plug is the same as the sierra diff fill plug.

the breather hose is -3 and you could easily make one up. Its a male / male fitting into the tank. Bulkhead fitting into cam cover with copper crush washer. I put the nut on the outside so could see if it came loose rather than it drop into the engine!

the hose uses mini olives to make a seal onto the plastic fluid carrying pipe inside.

Thanks

What do you mean by -3

Also is there anything special with the bulkhead fitting? I heard there was some sort of restrictor in it - I plan to use a non-return valve so maybe that's not an issue

 

[Wrightpayne]

-3 or dash 3 is a hose & fittings size - front flexible brake hoses are an example.

The kit from caterham only included a plain hose. Some people fitted a non return valve to stop the Apollo draining once engine turned off. This was to aid oil pressure build up when restarting.

Now you mention it pretty sure the fitting in the top of the apollo was caterham specific - I think it only had a fine hole in it to restrict flow.

This is still available.....

And this - images might be useful.

interestingly the left hand drive kits are cheaper!

This is a shot of the cam cover fitting. I think (and it only a think!) the size of the orifice is important. If the hole was too large it might reduce oil pressure and discharge [too much] oil with the air into the cam cover. 

[AndrewE]

Thanks

I have the tank plus the sandwich plate and two large hoses (although they have 90 degree fittings both ends so may be from a LHD car)

I also have what I believe is a NRV* so now just need to make up the top hose - not sure whether to mount NRV direct to Apollo tank top fitting or direct to cam cover. I assume with NRV I do not need a restricted bulkhead fitting. So what I would like to know what is the thread size of the top tank hole?

* What I think is a NRV looks like the images on Think Automotive but has the word HINGE stamped on one of the flats on the hexagonal end pieces - is that to tell me that that end is the INLET end?

Finally is there an easy way of finding out the thread size without resorting to detailed measuring and my Zeus chart?

[StevehS3]

Andrew, my NRV is in-line rather than fitted to the tank or cam cover. Others might have fitted it differently though.

[AndrewE]

Thanks Steve,

I have read of some fitting it direct to cam cover although i suspect in line imay be better (especially as you can secure it somewhere and there is less strain on the cover)

Does yours have any markings?

 

[StevehS3]

The cam cover is soft, thin alloy as you will see when you drill it so I think it is better inline. Mine is secured to a chassis tube with a couple of zip ties.

I am away and will check the valve on Friday but if you blow down it you can determine which way it goes.

[AndrewE]

Quoting Wrightpayne 'from memory the drain plug is the same as the sierra diff fill plug.' 

These seem NLA - are there alternatives for bottom Apollo tank plug or does anyone know the thread size?

[Wrightpayne]

There are some gearbox specialists known to the caterham community - road & race transmissions, SPC and BGH geartech. i’m sure one will be able to supply one.

for my piece of mind whip the plug out of the diff and check it fits!

Found this on the caterham parts website but out of stock. Their part number is actually the ford FIN code

http://caterhamparts.co.uk/fittings/290-filler-plug-differential-a-gearbox.html?search_query=Sump+plug&results=191

 

fin code is 6118746 and part no 83BG4N202AC google auggests M20 x 1.5

[Wrightpayne]

Bingo

just check the size!

 

[AndrewE]

Thanks, I also resorted to google and found it shown as M20 x 1.5 

Will go and measure the thread (and may do the 'take plug from diff' method)

Thanks again

Next thread to work out is the top breather hose connection. It doesn't seem to be JIC or metric so could be BSP as per the temp sender

Blatmail me I’ll dig out the invoice from think with all the sizes on it as I’ve just had a new pipe made up with the NRV in it

[StevehS3]

Hi Andrew, I had a look at my NRV and it has the word HINGE on the Apollo tank side of the valve.

[AndrewE]

Thanks Steve

 

I gave mine a blow and eventually it opened up one way

 

Andrew

[StevehS3]

Great, sounds like you are pretty much sorted with everything.

[AndrewE]

Thanks Steve, yes

 

Is there a specific location for the bulkhead fitting into the cam cover ?

[StevehS3]

Here are some photos. I don’t think it needs to be mm perfect and I remember it was obvious with the cam cover removed.

 

Here are some photos of where it fits. I don’t think it

 

[AndrewE]

Superb, many thanks

Andrew

 

[AndrewE]

So I have most of the bits needed but I am still struggling to identify the thread size of the top boss on the apollo tank

it is not 1/8 BSP or 3/8 BSF

Can anyone help tell me what it is?

 

[SM25T]

Could it be NPT ?
