Costas Posted May 29, 2019 Posted May 29, 2019 (edited) I note that LEGO have released a reinforced version (bb875) of their small 6L pump where they have beefed up the material around the base of the pump. I suspect that the following problem is why they released a reinforced version in 2018. I have a number of 18482c01 pumps which were sitting around in my spares currently unused. I needed one today for a small compressor project and when I put it to use I noted that I had an air leak in my system. Upon closer examination of my pressurised components I tracked the issue to a leaking pump. I placed it in some water (under pressure) and found air escaping through the body of the pump. Under some magnification I noted what appeared to be stress fractures in the main body of the pump - These run 360 deg around the whole base. Note that this pump was new/unused - I also went through my spares inventory (6 new pumps in total) and found another one with the same problem, so 2 out of 6 seemed to be affected - although the second pump exhibited fractures around its base it was still airtight. Just wondering whether others have experienced the same...? Below is closeup where you can see the fractures running lengthwise along the base. There is a thread a while back discussing a similar issue on an earlier pump variant that exhibited a similar problem but that may have just been a one-off: Edited May 29, 2019 by Costas Quote
mwyns Posted May 29, 2019 Posted May 29, 2019 I had the same problem with the pumps of my 42043 and 42053 sets after 2 of 3 years. Both where replaced without any problem by Lego. Quote
Costas Posted May 30, 2019 Author Posted May 30, 2019 Ok - Thanks... I'll do the same and request a replacement. Quote
rm8 Posted May 30, 2019 Posted May 30, 2019 have the same problem. My leak hole is near LEGO sign, around the base also Quote
Maaboo the Witch Posted May 30, 2019 Posted May 30, 2019 Guess this is why TLG issued a revised version. Hey @Costas, make sure you get that one. Quote
Costas Posted June 21, 2019 Author Posted June 21, 2019 (edited) Just to follow-up, LEGO Service replaced my spare pumps with the reinforced version bb875. All good...! Edited June 21, 2019 by Costas Quote
trinitechnic Posted June 21, 2019 Posted June 21, 2019 @Costas, Good day, can you please explain the process of getting lego to replace these? I myself have at least ten of these and stress fractures in four of them... Quote
Timoonn Posted June 21, 2019 Posted June 21, 2019 (edited) Well, its time to contact Lego Service again Edited June 21, 2019 by Timoonn Quote

Go to the LEGO website specific to your country and look for the 'support' link. In there you will find steps to replace broken and missing bricks etc - I just used that link and then entered my details etc... Quote
trinitechnic Posted June 22, 2019 Posted June 22, 2019 Thank you for the reply @Costas and @Timoonn Quote
Mantarri Posted June 23, 2019 Posted June 23, 2019 I bought a Merceds Arocs set off BrickLink awhile back, as I bought it used, I decided to fix it myself, just put some super glue over the affected area, just a tip to any future thread readers who can't get a replacement for whatever reason. Quote
i really dont know Posted March 13, 2021 Posted March 13, 2021 On 6/22/2019 at 11:32 PM, MisteryMan said: I bought a Merceds Arocs set off BrickLink awhile back, as I bought it used, I decided to fix it myself, just put some super glue over the affected area, just a tip to any future thread readers who can't get a replacement for whatever reason. I did this on some of my old pumps, it didn't actually help. You can check by putting the bottom of the pump in a container of water, the air inlet is through the top. Might have helped if I prepped the surface a bit better though. Quote
pleegwat Posted March 14, 2021 Posted March 14, 2021 Pumps can also leak internally, which is not as easily fixed. Quote

Found that out while building my Arocs, and was almost finished ... Quote
