Iain T Posted April 29, 2020 Report Share Posted April 29, 2020 Morning All, When I unbolted the adaptor from the block the assembly 'exploded' into its constituent parts and fell into the dirty oil pan! I assume the threaded banjo tab is only there to align the centre part and spring while bolting assembly onto the block. This tab retains the centre part and spring, am I right is assuming to reassemble providing the centre is proud of the main body ie positive pressure on the centre seal, the system will work or is there a set offset distance? Thanks as usual Iain Link to comment Share on other sites More sharing options...
Nigel Clark Posted April 29, 2020 Report Share Posted April 29, 2020 These adaptors can be tricky. You appear to have the later version with the spring-loaded clip on the central mounting bolt. It's very important this is fitted correctly, with the clip floating on the plain section of the bolt above the thread. These clips can ride up the thread, which will cause leakage, sometimes inside the adaptor so the oil can bypass the filter. Service kits are available for the adaptor: https://rimmerbros.com/Item--i-RR1238SKIT Nigel Link to comment Share on other sites More sharing options...
Iain T Posted April 29, 2020 Author Report Share Posted April 29, 2020 Thanks Nigel, I bought a service kit from the club. I don't have the adapter here but from memory when I spun the clip down the thread the centre piece locked up meaning the original bolt was incorrect thread length? So it seems this may have been fitted incorrectly when the engine was rebuilt 10 years ago! I haven't tried the bolt in the club kit, hopefully this will be OK. Thanks very much for your help.

Prince Brainier of Meccano Posted September 20, 2020 Report Share Posted September 20, 2020 Are those 2 holes for an oil cooler if drilled and tapped for the flexy hoses? Link to comment Share on other sites More sharing options...

I believe that's why they're in the casting but I'm not sure whether there's a drilling in the non-cooler version that would need to be "undrilled" before making it a cooler type.

There is just such an internal drilling in the non-cooler versions. For the same reason just blanking off the oil cooler tappings on the cooler version does not convert in the other direction. If you do that you’ll get no oil circulation at all....... Nick 1 Link to comment Share on other sites More sharing options...
Iain T Posted September 21, 2020 Author Report Share Posted September 21, 2020 I don't have an oil cooler so they are blind drillings. Why are they there? Iain Link to comment Share on other sites More sharing options...
johny Posted September 21, 2020 Report Share Posted September 21, 2020 Are they drillings or part of the casting used for both cooler and non cooler applications? Either way they indicate where the holes have to be should you wish to convert to using a cooler... Link to comment Share on other sites More sharing options...

Because they're not drillings, they're cast. Having them there allows a common casting to be used for both versions, which reduces cost (quite significantly) and means you don't have to pay as much for your adapter.

Prince Brainier of Meccano Posted September 25, 2020 Report Share Posted September 25, 2020 Is it safe to assume oil comes through the outer gallery into the filter and then to the engine oilway through the hollow fixing bolt? Link to comment Share on other sites More sharing options...
johny Posted September 25, 2020 Report Share Posted September 25, 2020 yes correct, on some spin filters you can see the flaps of the non return valve through the outer holes so thats where the oil goes in.... Link to comment Share on other sites More sharing options...
