What oil filter

[miker519]

Hello all
I am new to the minor owners club only joining at the NEC show on Saturday and collecting my 2 door saloon on Tuesday.
I have a simple question I want to give the car a service but do not know which screw on oil filter to get, the one that is fitted is a crosland 573 but i do not know what vehicle this would refer to? to order a replacement.
Your assistance would be appreciated.
Best regards MikeR

I get mine from Halfords , ask for the classic Mini oil filter .

[panky]

But not the later MPI filters as the tread is different.

Welcome, good choice of car and club, hope you enjoyed the show. There are various equivalent filters that you can use, including:
Cooper G714
Direct Components DTF1
TJ FB2099
Fram PH966B
Champion C103
Wix WL7098
They all have a 3/4" - 16 thread.
I usually find that the Fram is a good one to search for.
I'm sure you know that you need 20/50 multigrade oil, not the more widely used (these days) 10/40. The gearbox uses the same oil as the engine.

[Myrtles Man]

The Halford's version is HOF203W.

What ever screw on oil filter you use - fill the filter with engine oil before fitting. This helps get the oil around the engine quicker so reducing the possibility of bearing knock.
Smear the rubber seal with engine oil and only hand tighten the filter to the filter head.

The last couple I got were ALCO SP-828, as simmitc says, it's a 3/4" - 16 thread.


Crossland Filters went under about 15 years ago and the name was brought by Eurocarparts, but even they don't seem to stock Crossland any longer.

There's a few conversion websites out there, that included hundreds of equivalents.
This one is quite a reasonable site: https://www.autodoc.co.uk/car-parts/oem/6041176

So all these are to OEM spec 6041176, but you'll notice there are small differences in height.

So, your car has been given a Spin On Filter conversion, it may or may not have had the bottom of the engine bay cut away slightly to make it easier to fit the filter.
These different filters can be anything from around 70mm to 90mm in height. Typically around the 80-85 mark.

Thanks To all for the help and advice

another question Raised
Thought the gearbox used EP90?
Regards MikeR519 ?

[simmitc]

NO! As I wrote previously, the Minor gearbox uses the same oil as the engine. Using EP90 will not do it any good. Only the back axle and steering rack use SAE90. If you have already used EP90 in the box, then drain, flush, and refill with the correct 20/50.

[myoldjalopy]

Unless the OP has gone and bought himself a MM sidevalve. I believe these earliest cars did use EP90 in the gearbox......but, yes, if it has an A-series engine then the gearbox oil will be 20/50 engine oil.

[philthehill]

Unless the gearbox has been changed to a Ford Type 9.
The OP has not specified the size of the engine or type/make of gearbox fitted.

[simmitc]

Good points. At times we all expect things to be standard unless the poster specified otherwise, but Mike is a new owner, so yes, we need to confirm the engine and box fitted to the car.
Mike, could you post a photo of your engine and confirm if the gearbox is 4 or 5 speed; just to be certain.

[geoberni]

I didn't even know you could do a Spin-On Filter conversion to the MM Side Valve Engine....
It seems you can, however flipping expensive, about 3 times the price of the A Series engine conversion kit.

Let's see what MikeR comes back with....

[philthehill]

As an aside and with regard to a spin on oil filter for the 918cc SV engine there has been considerable discussion on this web site and if I remember correctly the kit in the link below is suitable and at a reasonable price.

That looks a better option than the one I found. It's going to place it down the side of the engine much like the original, whereas the one I found is going to stick out like the 803 one does.

I used a mK2 escort oil filter which seemed to work fine, on the gearbox oil personally I cannot see why with advances in tribology over the last 70 years anyone would use an engine oil in a gearbox now (particulalry after tearing a few boxes down), I use a multigrade gear oil (75w90)which has given no problems, the only modification to our gearbox being a lip seal on the front.

Everyone to their own though, if you do use an engine oil make sure it is the classic type with ZDDP.

[philthehill]

One of the main reason for using engine oil in a Minor gearbox is that it clears the baulk rings quicker making synchronising the gears that much easier.

I sure that would be the case with the traditional EP gear oils (hence why boxes like LT77 used ATF) , the gearchange with a modern multigrade 75W90 GL4 gear oil in our re-built box seems fine though.

It would be very interesting to do a back to back dyno test, of the 4 boxes I striped down the one which had been running in EP oil showed very little pitting of the layshaft or gears, the others all had considerable amounts of pitting, not knowing the history of the boxes it's difficult to draw conclusions but knowing that gear oils are much better at maintaing a film under extreme pressure leads me to believe this could be a significant contributory factor.

[philthehill]

The last thing you want on a Minor gearbox synchro baulk ring is extreme pressure oil. You need a oil that is quickly cleared from the baulk ring.
Everything else in the Minor gearbox can cope with EP oil.
