DAF T244 Cab Rams

Postby Brian-reynolds » Thu Oct 11, 2018 10:20 pm

Cab Rams....

For those that do not know, the T244 rams seem to be failing quite regularly now between the DAF owners, so some time back, after mine failed and I had to resort to buying a used pair and a pump from Crouch Military Sales for £300, I decided to try and give them a service....

After contacting numerous hydraulic companies, and being told by all of them that they cannot be serviced, I managed to strip one of my rams and find out the cause of all the failures.

It was one of the seals, obviously, but the seal was not available to purchase as these rams are not designed to be serviced, just replaced, so after the strip and finding the failed seal, I found a company that could machine a new set of seals for me, so after I placed the order and took delivery of said seals, I embarked on the assembly....

I have now managed to give one of my spare rams new seals, and after assembling it last night and leaving it on test over night it has actually worked!!!!!

Now I am going to fit new seals to another ram I have in stock, and after testing that, I will fit the pair to my truck and see how they perform.... If successful I will then get some more seals made and service my remaining 3 rams.....

I will be back with the results.

As a foot note, these things are absolute bastards to get apart and it took 2 of us to get the first ram back together.... no wonder hydraulic people say do not bother....

Cost of seals £25 per ram.....

Good work Brian, there's nothing like being told "can't be done" to encourage you
An old craftsman told me "man put it together, man can fix it"

Top result Bri, I take it you went with the heat-lube-and-slide method?

I did give it some serious thought.... but it did slide over the piston relatively easily.... with help from Mark!

I had to fit a couple of rubber 0 rings into the first slot to allow the seal to pass over that slot and into place, result.

The test rig went OK, and it is still fitted upside down there.... I now need to find a better way of stripping the second ram and fix that.... then place another order to have some more seals made then I will have 2 1/2 sets of rams spare (but accounted for.... you and Simon!)

Thanks Steve, I am very hopeful at the moment.

A second ram "serviced" today and sat on the test rig for the night! Well chuffed!

May not mean a lot to the members that have modern vehicles, but the DAF owners cannot get new rams if/when they do fail, and every hydraulic company I and others have been in contact with say they are impossible to service, and I certainly do understand where they are coming from, but I think I have done it!

Andy, this is something you do need to do before you go off, if they work now and are old, they will break at some point!

Maybe....

I now have two "serviced" rams fitted and am pleases to say they now work! How long the seals will last is anybody's guess, but it should be around 10 years or so!

Any DAF owners want theirs fixed, just PM me.... I will need to order some more seals to be made....

Hi Brian, what are you suggesting? Service them before we leave or get the service parts and do it when they fail?
May need you to talk me through it all!

cheers
Andy

Hi Andy, now that is a question.... It is VERY difficult to get them apart and not something to be done without a few home made tools, the sort of things you will not have with you, so you will be stuffed.

So far all 3 rams I have taken apart have had the same seal go, but they are all probably old and original, so I would recommend fixing them before they break.... but it is a gamble. If they do break you can open the cab using a jack and some timber, but run the risk of twisting the cab which could smash the windscreen... I have not done that, and have my doubts that it can be done, but another chap on another forum says he has done just that....

You can also tie a strap to the cab roof and use another vehicle to pull the cab forward, but I do not know how you stop the rotation as I think the rams stop it rotating too far...

Also to remove the rams, you first have to tip the cab to remove the split pins from the big pins... I have done this with the cab down, but it took ages and a good amount of choice words! I ended up jacking the cab up just a few inches to access the split pins, but was very careful to have the cab supported on both sides with good lengths of wood as well as the jack.....

I think the best bet is to give me a shout and we can talk about it....

I also need to get some more seals made as I only had one set manufactured till I could prove that it could actually be done.... there were quite a few times when I thought the professionals were right in that it could not be done....

I also need to buy some more oil as I have used about 2 litres testing and spilling it on the floor and some of it up and over the walls!

Give me a call buddy when you get a moment.
