SiC Posted July 19, 2020 Share Posted July 19, 2020 It could probably be salvaged but needs a full rebuild. Could that crank go into the rebuilt 1300FWD lump? Link to comment Share on other sites More sharing options...
Yoss Posted July 19, 2020 Share Posted July 19, 2020 This is my bible. A very tatty and well used (not just by me, it obviously came from a garage, it's covered in greasy fingerprints and alterations. It is a thing of beauty) original parts book. They changed over at RD4036 from a parallel to a tapered front crank. They had trouble with the front pulleys coming loose. Possibly because there is a lot more centrifugal force going on with the starter ring carrier. I don't know why a tapered one grips better, in my mind it looks like it would fall off easier but it's something to do with physics which I don't understand. But it works, they really don't like coming off. Normal pullers don't work. And they don't slide off, you keep hitting them and they go with a sudden bang. A normal 1300 RWD crank should drop straight in. I'm trying to think off the top of my head if the FWD starter ring would hit anything if it was installed in a RWD car. Not sure.

GingerNuttz Posted July 19, 2020 Share Posted July 19, 2020 I reckon by using a Herald GE timing cover the fwd engine will work with the tapered crank. Link to comment Share on other sites More sharing options...

He does indeed and plans are already in motion to rip the timing cover off and see if we can cobble together something that works. captain_70s, somewhatfoolish, SiC and 1 other 4 Link to comment Share on other sites More sharing options...

A rwd crank should drop in, issue being it'd have to be a small journal crank (my mk4 Spitfire lump is a large journal example), and they're the expensive ones! 5 minutes ago, GingerNuttz said: He does indeed and plans are already in motion to rip the timing cover off and see if we can cobble together something that works. This. The secondary plan is to take the two pulleys to a engineering workshop and have them combined/modified/made to fit the Dolly timing cover. The other issue being crank balance. With the flywheel being at the FRONT of a fwd engine rather than the back I have no idea what difference (if any) chucking that weight onto the opposite end of the crank for a rwd application will do.

Yoss Posted July 19, 2020 Share Posted July 19, 2020 I think you'll find the FWD just had a smaller flywheel at the clutch end to compensate. Also, perhaps I should mention this again before you throw it all together. There's no dipstick hole in a FWD block, that's in the gearbox. But the casting is still there it just needs drilling out. You don't want to realise that just as your filling your new engine with oil. captain_70s, GingerNuttz and jaypee 3 Link to comment Share on other sites More sharing options...

Yoss Posted July 19, 2020 Share Posted July 19, 2020 Glad to hear it, I didn't want you finding that out too late. I forgot earlier that you can remove the starter ring from the front pulley. It's just six bolts. Then you are just left with a normal pulley. Link to comment Share on other sites More sharing options...
captain_70s Posted July 19, 2020 Author Share Posted July 19, 2020 Aye, that's what we've got! We were wondering what all the bolt holes were for... ? I'd gotten it into my head it must be the arse end of the crank that was different for fwd applications, me and @Jikovron took measurements from that end to compare to my Spitfire engine and found everything identical but we only checked the distance between block/pulley groove at the front which is the same... I couldn't get the pulley bolt off my engine so I never actually got a look at the end of the crankshaft itself. I never even considered the fucking flywheel and starter would be at the wrong end because the fwd gubbins would be in the way! Link to comment Share on other sites More sharing options...
GingerNuttz Posted July 19, 2020 Share Posted July 19, 2020 The bolt holes are for attaching another pulley for supercharging ............ CreepingJesus, Tickman, jaypee and 5 others 6 2 Link to comment Share on other sites More sharing options...

Also gave him some dangerous fucking plans for massively overpowered BL shitboxes. ?

captain_70s Posted July 19, 2020 Author Share Posted July 19, 2020 I failed to take any pictures today, but @320touring kept a decent record of today's proceedings... Your average street furniture circa 1995. Fucked engine Flywheel tae fuck. Crank pulley tae fuck. Timing cover tae fuck (after wrestling with one stuck screw for ages) Timing assembly tae fuck Tensioner was fucked, chain was slack as buggery, teeth on the sprocket were fuuuuuuuuuuuuucked. Backplate tae fuck, and the start of cleaning... There was quite a lot of cleaning/wire brushing/sandblasting... Not fucked engine On the stand with aid of Dolomite backplate Removal of head studs because some had damaged threads. At this point @GingerNuttz had gone off with the cylinder head to the workbench and started porting it because he isn't building anything featuring the levels of casting flash BLMC considered acceptable... Looking at two very different crank pulleys featuring two very different nuts and two very different oil seals... This was during a period of a lot of pondering and a lot of thinking about how we could actually get this engine to function in a rwd application... (No, I'm not going to use that head gasket on the new engine, it was just a cushion for the head when in transit.
