90/95 series assist ram seals

Post by Tractor Tom » Fri May 14, 2021 12:11 pm

I'm putting new seals in my three point linkage assist/assistor ram, on a 1390. I purchased a seal kit which is not for a 1390, for some reason 1390 is not listed but it is for 1290 1490 and 1394. Anyway the seals look the correct size. The main seal is an o ring and leather washer. However, there is a buff/cream coloured lip-seal in the pack. It measures like it is a replacement for the o-ring and leather washer (more modern?) but I have contacted Sparex with the detail and they have done the 'modern thing' of not replying. Picture attached. Cautious me wants to put the o-ring and leather washer in, bold me wants to put the more effective, modern lip seal in; if that is what it is.

My resized .jpg photo is invalid. To add confusion Sparex show two blue seals extra https://gb.sparex.com/seal-kit-57975.html on their website, not one buff/cream one as in my kit.

Buying from an expert can pay off, as they are able to answer questions around parts they supply, please see http://www.davidbrownparts.com/Hydraulic%20System.html Please note that some seal kits include seals for more than one design.

I'm not against buying from DavidBrownParts (DBP), but I already have the seals. I asked the supplier what the extra seal is and they didn't know, so they asked Sparex, who replied to them in about an hour or so (helps not being an end of the line nobody). Sparex just said like for like. I reckon the o-ring and leather washer was replaced with a lip-seal at some point in production and Sparex put it in the kit to cover all bases. Annoying, as I want a lip seal but I'm not keen on being a guinea-pig, but I am tempted to take a 'hit for the team' for science (could be an oversize or for a different ram even). But it is confused that their online picture now has an extra two blue seals (mine is cream/buff/off-white) and they look different sizes. If Sparex don't know it's a bit of a guessing game. The DBP picture confuses further as there is one extra blue seal and no o-ring for the cap to body seal shown. I'm not saying it wouldn't be supplied or it isn't under its leather washer. Obviously after being ignored by Sparex and them not knowing about their own product, I'm not an immediate Sparex fan-boy, but I see the DBP kit is genuine CHN. It has been known for manufacturers to buy the aftermarket products and rebrand them as their own (ie CNH etc.) and double the price, just sayin'. And CNH aren't well known for giving a ... about David Brown parts. Unless someone else has a heart-warming story about their local Case IH stealership getting a conscience that went against their better business nature. Ram might still leak after all this, so if someone knows how to do an assist ram delete, don't hold back.

What I am trying to say is that David Brown Parts are dealing only with David Brown parts and that they know averything worth to know abot the parts they sell. Compere the prices, avaiability, quality and customer care and make your own choice. And yes, many seal kits include seals for different builds, but fit only the same type and size of seals as was used in the cylinder you repair. Deleting the asistor ram is really simple. Remove the cylinder and plug the hose that supplies oil to the cylinder.

That is valuable information about DBP and you obviously know what you are talking about. I will definitely put them in the mix in the future when I purchase parts, as I think it is good to support such people. I don't work my tractor, at least not at the moment, so I am very price driven when it comes to parts, eg postage. I'm not the best mechanic in the world, but at least I might make some others feel good about themselves, or just help out by sharing my experiences: https://www.youtube.com/watch?v=6XojXh-_YWY&t=184s

Sometimes being economical on parts can cost you more in the long run.

Ebay catches me like a mouse is lured to the trap by the cheese. I'm human: I'm flawed. Like Bart: https://www.youtube.com/watch?v=D0uUF3mK7Xk
