Jonny-Jimbo Posted January 13, 2018 Share Posted January 13, 2018 Hi all,I've got a Spit 1500 in the workshop for finishing off as the owner is now spending most of his time in Germany. When setting the valve clearances on the engine I found with my 8" long spanner I could turn the crank nut. I think therefore, it ain't tight! What's the torque setting for it? Needs a 1-13/16" socket I think, looks like a 1" thread, maybe a Whitworth one or something?In my Dolomite 1500 manual it says 150lf-ft, is that the same for Spitfire?

davidb5964 Posted January 13, 2018 Share Posted January 13, 2018 hi JonIf you need a large torque wrench i can bring one home monday.Dave Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted January 13, 2018 Author Share Posted January 13, 2018 Cheers John, always best to double check these things.Dave, I'll have to double check what mine go up to. I know my little one does 110lb-ft, think my bigger one will go to 250, but I'll check and let you know. I need to have a word with you about your Herald actually, I'll pop over tomorrow afternoon, I'm about to go to a mates stag do. Quote Link to comment Share on other sites More sharing options...
JohnD Posted January 13, 2018 Share Posted January 13, 2018 150 ft-lbs is a convenient torque to improvise.70kgs, normal adult weight, 150lbs in Imperial, on the end of a foot long lever!Or half that on two feet.John Quote Link to comment Share on other sites More sharing options...

However, I do possess a good torque wrench... Cheers, Dave. Quote Link to comment Share on other sites More sharing options...
JohnD Posted January 14, 2018 Share Posted January 14, 2018 On the contrary, Dave!110kgs = 242lbsIf 150lbs at 1 foot = 150ft-lbsThen 150ft-lbs = 242lbs at (1 x 150)/242 = 0.62ft or 7.4 inches.It's not quantum chromodynaamics, or even algebra! It's arithmetic!If you can work out the price of four tyres when you know the price of one, you can do this calculation.John Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted January 15, 2018 Author Share Posted January 15, 2018 In any case my 8" spanner undid the nut by hand, without trying, so either way it wasn't correctly torqued! Quote Link to comment Share on other sites More sharing options...

Jonny-Jimbo Posted January 16, 2018 Author Share Posted January 16, 2018 That method would also need the bar to be perpendicular to the crank and parallel to the ground, otherwise you have to factor in vectors etc. Quote Link to comment Share on other sites More sharing options...

Jonny-Jimbo Posted January 18, 2018 Author Share Posted January 18, 2018 Torqued up last night with my torque wrench and a chuffing great socket. I removed the started motor and used a pry-bar on the ring rear to lock it whilst my other hand gave a good tugging. The nut needed nearly a full revolution to bring to torque, so it must have been pretty damn loose.As is often the way though, doing one job revealed another issue... or two...Waterpump gland seal failed, cooling fan held on with two out of four bolts, every single stud and bolt on the engine to bellhouse face has the fasteners in the following order; nut, plain washer, spring washer... ideal. Also the engine backplate is bent. I wonder what else I'll find... Quote Link to comment Share on other sites More sharing options...
