david lewis Posted January 14, 2016 Report Share Posted January 14, 2016 hi all, i have bought a s/hand gearbox to fit my 13/60 which was purported to be good and came from a vitess but the rear flange is square. my prop flange is round,the prop bolts ok to the box so does it matter ? cheers Link to comment Share on other sites More sharing options...

Ben Caswell Posted January 14, 2016 Report Share Posted January 14, 2016 Surely if its a Vitesse box the input shaft is longer than the heralds Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 15, 2016 Report Share Posted January 15, 2016 Thats correct, providing the ages are similar you can drop the layshaft and swap the input shafts over later boxes had a tooth profile change and mix and match could be a noisy mistake povidint the coupling spigot is same and bolt dia its a straight fit but its easy to swap the couplings over Link to comment Share on other sites More sharing options...
Clive Posted January 15, 2016 Report Share Posted January 15, 2016 Surely if its a Vitesse box the input shaft is longer than the heralds And the input shaft is a larger diameter too. Link to comment Share on other sites More sharing options...
david lewis Posted January 15, 2016 Author Report Share Posted January 15, 2016 so are you saying that if the box is from a early vitesse it is not a straight swop into my 13/60 ? thanks for your replies. Link to comment Share on other sites More sharing options...
Clive Posted January 15, 2016 Report Share Posted January 15, 2016 Yep. Link to comment Share on other sites More sharing options...
DBGT6 Posted January 15, 2016 Report Share Posted January 15, 2016 If the box is 'early' i.e.1600 Vitesse it will be three synchro and will have a different input shaft - as will any six cylinder 'box. The square flange is normal, but if different to the current box in your Herald then you probably have a Spit IV box - with synchro on first. You can probably cobble the bits together, but may be easier to get the right box. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 15, 2016 Report Share Posted January 15, 2016 If it has one ,,,,,,,Whats the code stamped into the top face of the case or a photo pete Link to comment Share on other sites More sharing options...
david lewis Posted January 16, 2016 Author Report Share Posted January 16, 2016 just checked for the g/box number and it is prefaced gb so i think it is from a 1200 herald so it should fit my 13/60---is that correct ? heres hoping ! Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 16, 2016 Report Share Posted January 16, 2016 Yes that gb is herald up to the 12/50 When you fit the clutch hsg make sure you have copper washer on the lower fixing ,seal the threads of any other through the case fixings or you get a leak Link to comment Share on other sites More sharing options...
david lewis Posted January 16, 2016 Author Report Share Posted January 16, 2016 thanks pete--the bell housing is still attached so hopefully no problem.. the box on the car at the moment is a 4syncro with bearing problems so i want to fit the other box so i can contnue to use the car while the 4syncro box will be rebuilt at my liesure. cheers Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 16, 2016 Report Share Posted January 16, 2016 I would whip the top off and check for any missing 1st and reverse teeth whats the problems with the 4 sync ? pete Link to comment Share on other sites More sharing options...
david lewis Posted January 16, 2016 Author Report Share Posted January 16, 2016 there is a loud rattle from the box at tickover especially when cold which goes away when the clutch is depressed,its also evident when accelerating in 3rd gear. i have phoned and emailed mike papworth several times for advice and quote for repairs but have had no response whatsoever--strange ! so i may have a go myself. cheers Link to comment Share on other sites More sharing options...

mishmosh Posted January 16, 2016 Report Share Posted January 16, 2016 Fitchetts do an exchange box. Link to comment Share on other sites More sharing options...
david lewis Posted January 16, 2016 Author Report Share Posted January 16, 2016 Yes I know about fitchets but am not sure of the quality of there boxes--heard some bad reports. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 17, 2016 Report Share Posted January 17, 2016 I have rebuilt many boxes for members around here and far away, there is always a problem with exchange... for you are trying to balance used core with few NOS very few parts are manufactured new. so parts to revive something well past its designed life become harder to procure. compromise does not always give you utopia. tooth fatigue is one hurdle that is un estimateable, the main wear culprit is the under engineered ,weak mainshaft spigot and layshaft needle wear. using the later 18mm gives some life but then you need a input shaft to match. if you want a run to Luton for a natter and cuppa we can examine and devise a repair .

david lewis Posted January 17, 2016 Author Report Share Posted January 17, 2016 thanks pete ,i will take you you up on your kind offer hopefully in the spring when i have got the box out,i am away in bali and australia for most of febuary and march so not much is going to get done over this period. cheers Link to comment Share on other sites More sharing options...
Steve P Posted January 17, 2016 Report Share Posted January 17, 2016 I think Mike Papworth had his BT mail account hacked as i got spam purporting to come from him,ring him,very helpful chap and good service in my experience. Steve Link to comment Share on other sites More sharing options...
mishmosh Posted January 17, 2016 Report Share Posted January 17, 2016 I bought a 4 synchro from fitchetts 20 plus yes ago. Still good. Link to comment Share on other sites More sharing options...
david lewis Posted January 17, 2016 Author Report Share Posted January 17, 2016 i think the parts that were around 20 years ago were of much higher quality than some of the asian rubbish around these days. Link to comment Share on other sites More sharing options...
