I have a number of books,new and old,that cross reference filters for DB tractors and there are no filters available that are suitable without modifications for later Cropmasters,thirty series and 900 tractors. If cross matching filters are not the correct dimensions and specification they will not filter the oil. Filters that fit in the filter housing are readily available and being marketed for David Brown engines but without the appropriate sealing arrangement, they are useless and people purchasing these are blissfully unaware of the fact. Filters being marketed as suitable for a specific engine should be correct.
The filters supplied by davidbrownparts.com meet the specification requirements.

Thanks for the heads up Cliff but we need a supply of filters locally not have to order them from the UK only. It appears the main problem is the seals top and bottom of the filter. Is this correct?
Paper elements now are all full flow with little or no restrictions.

The seals are the problem. The filter as far as I am aware is unique to DB engines and that is the reason for David Brown Parts having then manufactured. I would be surprised if you can find a filter manufacturer that would be willing to produce a batch matching the original specification.

Cobbadog, I would urge you to stop searching for the filters locally, they are not available on the open market, and this has been told to you and others, several times. There is absolutely no reason for why you can not buy these filters from UK. A lot of people from America and Canada are buying parts from UK, as they get excellent service and correct parts first time, dealing with davidbrownparts. I can not understand why you say that you need to get the filters locally as the filters you buy locally are coming from countries like Chine, India and others. I think you, and others, need to get the correct parts. And one more thing, this discussion has no been going on for a long time, with no real results. Sounds you are obsessed with finding a substitute filter, no reason trying something others have done for decades.

Blimey,
the paper filter that DB parts use is a standard off the shelf filter (I cannot remember the part number though - I think it may be the same as those that fit the 4.0 DB4/5/6 Astons but I am not sure) - its not specially made, but the bellows are. The filters are also not that cheap as they are low production run items.

The club looked into a bit a while ago but the cost to have the bellows made up were not making it viable.

......so, if say someone in Aus / NZ bought a Cropmaster filter from say a supplier who specialises in these things, cross referenced it for definite, then looked to get the bellows made up by a local manufacturer but you`d need to order a lot to make it cost effective then job sorted. Perhaps the DB Aus or NZ club could look into it or a local entrepreneur in Australia etc .

The DB parts ones are not cheap but are good value when you look at a low production run / sales item, although the shipping probably kills it for the guys south of the equator. If you do as I suggest then it may not actually work out cost effective unless the DB club Aus wanted to buy say 200 pairs of bellows to get the cost down????

Not sure how much clearer you can make it - the tricky bit is yes you can use a filter and washers etc to save say £10/15 but when the seal is not right and a shard of metal ends up in the big end bearings its not worth it.

Cheers

Andy

Hi first there are probably 100s of DB owners in New Zealand alone who would like to purchase a filter localy even to the extent of some taking the old filter out and washing it . The DB housing is not a machined fit and a cast finish hence the use of cork end seal washers that work ok on this, if the total length of the filter and whatever end seals matches the length of original filter and seals there will be no problems. The last of original filters had rubber lip end seals and were fine but went hard after long use, but there is no reason why two small hydraulic seals the same size as the old cork seals could not be used and cleaned and re used with replacement filters as required. Here we have the cost of more than double the UK price + post that makes for very expensive parts that is why local available replacement service parts work for us.

Thank you once again db2d and ollek. Your accurate knowledge on this topic is duly noted and you are correct in saying that david brown parts have a brilliant service and I have purchased many items through them that cannot be purchased anywhere else like an engine rebuild parts and recently a rotary ignition switch. But when it comes to something as simple as an oil filter there can be no issues with another product so long as it met the original specifications of length, diameter, flow and the ability to be sealed successfully at both ends. None of us are tied down to buying only a certain brand of tyre or oil and the same can be said for a filter.
As stated cost is an issue in bot currency exchange and then postage which has of late become a big issue. Yes, nearly everything now is made in China and can be suspect as to the quality but then items can be made anywhere to a code and be as good as an OEM part. I had been involved in doing just that with the making of skid steer tyres to our Australian specifications but made at the source of the rubber in Thailand and are still a great success and still out sell and perform a Toyo product which was a leader in the market.
So in my humble opinion anything can be made to a specification and work, surely one company in the whole world does not have a monopoly on that.

I hope you are successful in your search for an oil filter that fulfills the necessary criteria on your side of the world.
Rear tyres for the David Brown 2D “600 x 22” are unobtainable over here along with 31x9 fronts for the older industrial tug tractors, maybe new ones can be found in your country.

Thanks for the kind thoughts Cliff. Unfortunately both those tyre sizes are not available here either. When ever a 2d comes up for sale you nearly have to buy the tractor just for the tyres if you really need some. There have been some very scarey looking tyres at some Rallies over the recent years.

Hi probably the only way around tyres is to put the original wheel centers on to suitable rims for tyres that are available and close to the right diameter this was done with old spooked steel wheels to tyre rims and the tractors are still vintage and easier to work with and move. cheers Geoff

Regarding aftermarket oil filters, on my 50TD crawler, I was having oil pressure issues,so I removed the existing filter housing (only one was fitted, not a twin set-up as shown in my parts book), made an adaptor block from 1" thick steel, bolted this to the engine block and remote mounted a canister filter on the back of the air cleaner bracket. The filter is the same as fitted to Perkins 6 & V8 cylinder engines, low cost and easily available. May not be original but does the job of filtering the oil and may prevent an engine failure due to defective filtering. I can post photos if required.

Good and helpful information there John.
It shows that another oil filter can be successfully utilised, not that much different from using an aftermarket oil filter inside the original housing providing you have the correct seal at both ends regardless of how that may be achieved.

Hi cobbadog have found the right end washers at my local Hose&Pipe store they are 1 1/4 " by about 7mm thick same as cork end washers they called them buna washers used for Cam Lock fittings and are suitable for oil or chemicals were a bit over $2 ech or they had Viton washers at $12 ech which they thought were not necessary for what i am using them for. I was considering cutting them from neoprene sheet but didnt need to as they were available ready made. So a Sakura filter EO-30120 and 2 washers and you are set to go. cheers Geoff

If they are not telescopic, just plain thick washers,they are not suitable in my opinion.
The correct, purpose made filters are available and unless a suitable direct cross matching version is obtainable this is what should be used.

Hi Cliff they are the same measurements as the old cork ones and should seal better so cant see any problems and will be using them myself,but if you want a filter with seals attached you can just drop in get the DB shop one. cheers Geoff
