Lebro Posted November 1, 2020 Report Share Posted November 1, 2020 Is the TRshop offering the same as this one? & do have to modify the housing or is a new one supplied ? Bob. Quote Link to post Share on other sites

Bob. No mods needed except perhaps the length of the flywheel bolts. They protrude through the crank flange and may touch the seal. As an aside I thought you may have converted your own existing seal. http://www.tr4-racing.de/download/splitseal.pdf Cheers Peter W Quote Link to post Share on other sites
rvwp Posted November 2, 2020 Report Share Posted November 2, 2020 Hi Roy, I don't recon you will get the seal conversion kit made by Bastuck any cheaper than £89.50 from the TRShop. You also have the option to effectively 'hire' the alignment tool by purchasing and getting a 50% refund when returning it. I did this as it was 'simples' .

You are quite correct, I could easily modify my own, but where do I purchase the lip seal only ? I presume the "mandrill" used to modify the metal parts is the same thing as the centering tool to fit the seal to the block ? Bob. Quote Link to post Share on other sites
Motorsport Mickey Posted November 2, 2020 Report Share Posted November 2, 2020 Remember the dimensions for the oil seal scroll centring tool in the workshop manuals is incorrect, from memory 4 thou too large, another reason why the TR leaks from the rear scroll.

The seal only for the kit is sold separately by Marx for 31 Euros - see here http://www.tr4-racing.de/eng/madmarx-racing.html Peter W Quote Link to post Share on other sites
stuart Posted November 2, 2020 Report Share Posted November 2, 2020 TR Shop sell the seal or the kit, FWIW I have the fitment tool in both versions. The Christian Marx type and a factory original tool if anyone is stuck I can hire them out. Stuart. Quote Link to post Share on other sites
Lebro Posted November 13, 2020 Report Share Posted November 13, 2020 What is the difference between your two fitment tools, apart from the 4 thou error in the workshop manual he talks about. Bob. Quote Link to post Share on other sites
stuart Posted November 13, 2020 Report Share Posted November 13, 2020 The rear section of the Mandrel for the Christian Marx seal is much larger Quote Link to post Share on other sites
Lebro Posted November 13, 2020 Report Share Posted November 13, 2020 That puzzles me, surely the scroll part of the cm seal is the same size as original? His website shows how to modify a standard seal to take the lip seal, he does not touch the scroll area. Bob Quote Link to post Share on other sites
Lebro Posted November 14, 2020 Report Share Posted November 14, 2020 Stuart. Did you mean you have the smaller dia mandrel to use with the seal which required machining off the scroll ? Quote Link to post Share on other sites
stuart Posted November 14, 2020 Report Share Posted November 14, 2020 (edited) This is the original type mandrel above. The one I have is an ex-factory one same as this and I have the Christian Marx one as well, pictured in previous post, I cant picture them side by side at the moment as the original is out on loan. I never go for the machined off type as theres too many variables and once done theres no going back. Stuart. Edited November 14, 2020 by stuart Quote Link to post Share on other sites
Lebro Posted November 14, 2020 Report Share Posted November 14, 2020 Ok, but I can't see why the "original" should be any different to the Christian Marx one, other than the 4 thou error in the book CM talks about in his installation document Bob Quote Link to post Share on other sites
