2l pinto + lucas, inertia type, starter-motor

[Comadis]

hi alltogehter,


was quite happy that my 1.6pinto has been replaced by a 2l one...everything was put together..turned the key and? nothing...strange noise from starter.

short investigation:

1.6pinto-->inertia type starter motor (lucas type, with separate solenoid), the starter-ring gear has 100teeth.

the 2l flywheel uses a 135teeth gear...so my question is:

is there an inertia starter motor existing for this flywheel or do i have to use a pre-engaged one?


are there alternatives?

I think you will have to use a pre-engaged starter on it, apart from the different number of teeth, the chamfer on the teeth is on different sides of the flywheel on the two types.

This is true, but the alternative is to fit a new ring gear to the flywheel.

Obviously, this turns a simple starter motor swap into a major, engine-out job, but if you have no alternative (for example, if the solenoid on a pre-engaged starter fouls a chassis tube, as it did on my Crossflow engined Westfield), then it can be done.

If there's space, the sensible solution is definitely to stick with the pre-engaged starter, though.

lots of space.....so pre-engaged motor necessary...

not again engine out...lol...it came in on saturday!!!


what do you think of such ones:

are they worth the money (compared that you get new-old stock pre-engaged ones from lucas for 20,-pound sometimes at ebay)?

No, not worth the money, unless you have a race engine, running high compression, carbs and a fixed advance curve (non-vaccuum or mapped) ignition, in which case the standard 12V starter can lack the guts to turn the engine over when cold.

[Comadis]

compression ratio is now 11.1 and fixed advance curve at the moment with a about 17-20 degrees timing.

the inertia type had hard to crank with this timing on the old low-compression 1600 engine.

are these "modern" starters of a good quality or is it something imported /manufactured from china?

If the starter had a hard time cranking the engine, then a geared starter motor might be a good idea, assuming you have already sorted the main battery cables and earth straps to ensure they are up to he job and that you're not getting a high resistance somewhere.

As usual with your posts, Comadis, you need to give all the relevant information before we can give you a valid answer. Computer forum advice is like computers in general: garbage in = garbage out.

The geared starters I have seen appear to be of high quality, but I haven't enough experience of them to vouch for their longevity.

[Comadis]

battery-cable, earth cable..everything new, highflexible wire of 35 square-mm, short wires as battery near starter.

but small battery to save weight.

I built a 2ltr Westfield many years ago with a recon Pinto....

Never realised some starters have 9 teeth and some have 8....could have saved me a lot of time and trouble, as there was a horrible grinding noise when the starter hit the flywheel.......

[oakdale]

Also depends on what cam you're using (a longer duration cam actually reduces starter loading due to compression loss at cranking speed).

I've built a 2.1 Pinto with 11.7 cr, 292deg cam and 18deg static timing and there was no problem with the standard pre-engaged starter.

[Comadis]

problem is: i´m located in germany...but driving a RHD car...this means the starter motor is on the left side. if i use a pinto starter with domestic specification the solenoid will show downwards and will soon get torn off.

this means i need to source something in uk...as standard starters are very heavy this will dramandously increase the shipping costs.

as the high torque starter has half the weight it might be at the end the cheaper solution (and the better, too -- i guess)

i found a new lucas pre-engaged motor at ebay for 20,-pound (NOT on an exchange basis), but the seller (a company) does not ship outside UK...what a pity.

Just a thought, unsure if possible but could you not fit the 1.6 flywheel ?, then use the starter ok? may work?

[Comadis]

sure i could...but:

1. the 1600 flywheel is not lightend.
2. engine-out job (engine came in this satruday!!!!)
3. 1600 means smaller clutch.
4. 2l flywheel is also balanced with the crank.

so not a really good idea!!

the starter motor is the easier way.

[Comadis]

have ordered the high torque starter last tuesday...arrived friday...that was quick. they shipped by DHL.

unfortunately the holes in the fixing flange havent been machined in correct position.

modified myself (10min. job) and it works.

but even with this geared starter motor the battery MUST be in good nick.(as some companies advertize "better start , even with a poor battery").

what i found in the meanwhile is this:

looks like these starter motors come from Taiwan, but this company seams to be a well known brand in asia.

that link is for 24volts, maybe that's your problem??

[Comadis]

the link i posted should only show the design of the starter....i didnt say that i bought such a 24V one...

i only wanted to say that these taiwan startes look more or less identical to the ones offered from several UK-supliers (cambridgemotorsports, burton, rallydesign)
