Stuart Wilson Posted September 20 Share Posted September 20 (edited) Well I've eventually got the engine for the Moss on an engine stand at work ready to take to pieces and rebuild. Only I think 10 years since the engine that was in the car died on the RBRR This one is a "replacement" one Edited September 20 by Stuart Wilson 2 Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted September 22 Author Share Posted September 22 1500 spitfire engine which will be getting a strip down and see what it needs. I'm thinking it'll need a fair amount. It'll be fixed to an overdrive gearbox, which will also need checking over. The main gearbox I'm reasonably comfortable doing but never done anything with an overdrive. So it might be sent to a specialist. Any recommendations for this? Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted September 23 Author Share Posted September 23 Sunday saw the start of the strip down. Should hopefully get a little bit done most days/nights after work. Trying to remember to take pictures as I go plus keeping a note of parts I'll need as it all comes to bits Quote Link to comment Share on other sites More sharing options...

If the OD is "known good" open it up, clean it, clean filters and put it back together - carefully. If it's unknown or bad - specialist. They are not impossible to work on, but any major work needs the proper set-up and testing. Are OD services still about?

thescrapman Posted September 26 Share Posted September 26 Looking at the followers the camshaft isn’t going to be great. pulled a similar set out of a 2500 engine, couple of the lobes would have struggled to open the valves Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted September 27 Author Share Posted September 27 Plan has always been a new camshaft and followers anyway Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted September 27 Share Posted September 27 I heartily recommend cams and followers from Newman cams. Not cheap, but good quality. 2 Quote Link to comment Share on other sites More sharing options...

Stuart Wilson Posted October 1 Author Share Posted October 1 Am I correct in thinking there are 3 main diff' ratios in Herald/Spitfire 4.11/1 3.6/1 3.8/1 Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted October 1 Share Posted October 1 Yes, 3.63, 3.89 and 4.11. On my 1500 with OD box I run 3.63. 1 Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted October 1 Author Share Posted October 1 A later job will be see what I've got fitted and look to change if necessary. Get the engine done then it'll be gearbox and diff 1 Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted October 2 Share Posted October 2 There's also a "rare" 3.27, used in Swiss Spitfires and GT6s and the 4.875 and 4:55 from the Heralds. But as stated the 3.63, 3.89 and 4.11 are the common ones. Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted October 2 Author Share Posted October 2 Knowing my luck with the Moss based on a Herald I'll probably have a 4.875 or a 4.55 Which would definitely need changing Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted October 4 Author Share Posted October 4 I'm off and actually at home for a day, so had a look in to the Moss garage Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted October 4 Author Share Posted October 4 While in the garage I uncovered the gearbox I acquired at about same time as the engine, so about 9 or 10 years ago. Yes it will need checked over as will the D type overdrive. What are people's opinion of fitting this gearbox to the 1500 engine? Or am I better with single rail?
