  4. Seized Brake Cylinder - Vitesse

    in Braking System

    Posted

    I changed rear brake cylinders about 5 years ago just stripped down to replace the rubbers as moving across to Silicone . Good job I did this as one cylinder was seized solid

    They were new when fitted . The brand was TB3 . I’ll clean out and see if the surface is corroded . Any suggestions as to a reliable replacement ? What causes the corrosion , the other 1 again new was fine

    the cheap ones are mainly Lucas 1500 distributers without the tachometer drive. I have no experience of new ones, I had mine rebuilt by the club shop. SimonBBC seems to have a good reputation. But most of the new ones don't have the vernier on the vacuum unit if that worries you

    I bought a new Delco copy with electronic ignition from SimonBBC for my Vitesse cost about £90 . It does have a tachometer drive . Having a vernier would have been preferable and the moulding looks a tad crude though 4 years on its working fine for me . I do carry a spare electronic ignition just in case cost about £30

    At the time I compared this price against a Lucas recon from Dist Doctor cost about £250 and this was for points

  9. Gearbox Cover - Vitesse

    in Bodywork & Fittings

    Posted

    The gearbox cover in my Vitesse saloon has always let in engine heat especially noticeable in the summer . On checking the fibreglass moulding it didn’t fit the curves in the floor on drivers side and there was a cutout for the diverter box so impossible to seal . So I’ve made a template and sealed to the floor and used rivenuts for a secure seal . The cutout for the diverter box has been sealed . Fitting was a pig though found that making all the holes in the cover oversize and using milk bottle caps as washers helped. No apologies for the pics as it doesn’t look very pretty but should keep most of the heat out now . To remove I have to remove the diverter box first which is not a problem .

  13. Spitfire Mk4 Differential

    You can buy Timken bearings for all of the diff (at least for Spitfire Mk. IV), unlike the gearbox bearings it's not a big issue and the cost is not that bad. Last year it was about £150 for the whole diff, I can dig out the part numbers if needed, but there's several different setups for carrier bearings depending on the exact year the car was built.

    the diff has the later oil breather

  14. Spitfire Mk4 Differential

    in Drivetrain & Rear Axle

    Posted

    I’ve got the opportunity of buying a Spitfire mk4 diff 3.63 for my Vitesse mk2 OD with 3.89 diff . The seller has stated “minimum backlash” 

    The 3.63 would have advantages with longer drives . I travel from Suffolk to the Wirral 230miles regularly and would like to use the Vitesse more on these runs .

    I know the diff would require 2 extra studs and I would also add a drain plug . At a minimum  the bearings on the inner axle shafts and the front flange oil seal and bearings would be changed and although I have not done this before reasonably comfortable about doing this . My question is how do I check if the diff is worth refurbing ? Does the diff need checking over by an expert or could I do the necessary tolerance checking . If work was required on the internals I know this would be beyond my capabilities and then part ex with Fitchetts  or hand over to Mike Papworth . Fitchetts current price for a recon is £540 which seems reasonable but what do you get with a refurb , accepting you won’t get anew crown wheel and pinion. 
    Any advice welcomed

  21. Changing to DOT5

    I believe thats why its recommended to do the change over to DOT 5 on new systems or at least flush existing ones with alcohol and then blow through...

    Buckeye doesn’t recommend Alcohol as it leaves a residue and Buckeye used a compressor to blow out the Dot 4

  23. Changing to DOT5

    in Braking System

    Posted

    When refitting the gearbox in my M2 Vitesse I must have strained the slave piping as there is a minor leak . Using the opportunity to move to DOT5 . Once I’ve cured the leak Is it simply remove the brake fluid from the master cylinder and replace with DOT5  and bleed as normal . I have already added a bleed extension so can bleed from the engine bay . The brake fluid is a few years old so looking to replace this with DOT5 as well . I’ve purchased 1/2 litre , will this be enough to do both jobs ? 
    Any tips appreciated
