TJSB Posted February 11, 2022 Share Posted February 11, 2022 (edited) Dear all, the diff pinion oil seal on the middle axle of my Crusader EKA needs replacing. I have tried the Manufacturer's Part Number (5091-257) and the NSN (5330-99-819-3008) from the ISPL through google and the suppliers I can find but no joy. Does anyone have a drawing of the seal or know of a someone who sells them? Does anyone also have the EMER or AESP for the job or know if any special tools are required and any relevant torque settings. Thanks in advance Toby Edited February 11, 2022 by TJSB NSN added Quote Link to comment Share on other sites More sharing options...
radiomike7 Posted February 11, 2022 Share Posted February 11, 2022 The pinion shaft on the leading drive axle is fully enclosed and does not have an oil seal, do you mean the input shaft oil seal? Any decent oil seal supplier should be able to provide a replacement if you provide the inner, outer and depth dimensions or take along the old seal.

TJSB Posted February 12, 2022 Author Share Posted February 12, 2022 Thanks, I do mean the input shaft oil seal. Taking the old one out is definitely plan B if I can't get a seal before stripping it. Anything of the right size I have seen available looks an odd shape, hence why knowing will be useful. Quote Link to comment Share on other sites More sharing options...
john1950 Posted February 12, 2022 Share Posted February 12, 2022 It will have Leyland hub reduction axles so parts and information should not be a problem. Quote Link to comment Share on other sites More sharing options...

Yes, it was known as the Albion bogie, part of the Leyland group. Quote Link to comment Share on other sites More sharing options...
attleej Posted February 12, 2022 Share Posted February 12, 2022 Dear All, It is actually a Maudsley axle made at Alcester. We just hope that someone had already ID'd the seal so that we could have a new one ready. The alternative is to strip it down, measure it up and then order the new seal. Fortunately they come very quickly from Simply Bearings. John Quote Link to comment Share on other sites More sharing options...

John You are absolutely correct John, early 6x4 Crusaders used the Albion bogie as Maudslay were still developing the through drive axle which was used on later models.

john1950 Posted February 12, 2022 Share Posted February 12, 2022 Every day is a school day. When I ran T45 6x4 Constructors there were 37 axle variations through the range, if I remember correctly. Quote Link to comment Share on other sites More sharing options...
