bond68 Posted February 20, 2013 Share Posted February 20, 2013 hi, anyone have pics or drawing of the front crankshaft pulley on 1300fwd? Ray Quote Link to comment Share on other sites More sharing options...
That Man Posted February 20, 2013 Share Posted February 20, 2013 Do you just mean for identification purposes? they have 6 x 5/16" dia holes in the front face for mounting the starter ring carrier.I can take a photo of one if that's any help.

Nick Jones Posted February 20, 2013 Share Posted February 20, 2013 Have a vague memory that there are two different versions...... can't remember what the difference is now though....Nick Quote Link to comment Share on other sites More sharing options...
That Man Posted February 21, 2013 Share Posted February 21, 2013 This is a photo of the pulley you'll needIt also appears that rimmers have some http://www.rimmerbros.co.uk/Item--i-145713 a bit expensive though Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted February 21, 2013 Share Posted February 21, 2013 Do some have taper fitting to the crank and some (early ones?) have parallel? I know the one I had was a taper fit as it was an absolute sod to get off but IIRC Josh Bowler used one on his supercharged Spit (used the bolt holes to attach the SC pulley) and the Spit Crnak would have been parallel..... :-/Nick Quote Link to comment Share on other sites More sharing options...
yogi Posted February 21, 2013 Share Posted February 21, 2013 Hi Nick, yes you're right the early cars had a parallel one but apparently they had trouble with them coming loose so changed to the tapered design which as you say can be a right pig to get off.

bond68 Posted February 22, 2013 Author Share Posted February 22, 2013 Hi, Thanks for all the info,did this taper nose crank appear on any other model? I'm going to put back old crank and buy new bearing shells so I have reground taper nose crank and shells available Ray Quote Link to comment Share on other sites More sharing options...
That Man Posted February 22, 2013 Share Posted February 22, 2013 Hi Nick,I believe your mate Josh used a 1500fwd hub/pulley on his supercharged spit, this would have been tapered originally and of the larger size of 1 3/8" dia (1300fwd 1" dia) which he then bored out parallel to fit the spit crank nose.Ray, the taper nose cranks are unique to the fwd cars, as it's just for attaching the starter ring to the front of the engine Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted February 22, 2013 Share Posted February 22, 2013 Pretty sure Josh found one of the early 1300 ones that fitted straight onto the small-crank Mk3 Spit motor. He's very good at finding ready made parts!Nick Quote Link to comment Share on other sites More sharing options...

I'd assumed it was a MKIV large bearing engine, maybe that's why the crank broke ?I'll have to revisit his web site if it's still up, as i'm planning to do something similar myself at some point ;) Quote Link to comment Share on other sites More sharing options...

I hope you have a lot of spare gearboxes! Or do you have any plans to improve the box, though I can't think what. I really must pay you a visit sometime, I think I would find it very interesting :).

Nick Jones Posted February 23, 2013 Share Posted February 23, 2013 http://www.justdrive.ca/gt6/josh/supercharged.htmlNot heard from Josh for a long while now unfortunately. Pity, he did some very clever work on that Spit. Was an animal with the supercharger!Nick Quote Link to comment Share on other sites More sharing options...

Yogi, yeah i do know what you mean, but i've done over 150,000 miles in various 1300's over the last 25 years most of which have been modified in some way or other and i've never broken a gearbox, worn them out yes, but never broken, maybe you've just been unlucky.As regards supercharging a 1300, as i'm planning to run EFI i'll have the ability to modulate the midrange torque to something the box can handle, i hope!

Canley's uprated 1300 input shaft/primary gear would do the same for the 1300 box Quote Link to comment Share on other sites More sharing options...
