Hallo friends,

back after some time, I wonder if there is any compilation for exact and trust worthy values for all kind of clearances and torque values for  Listeroids of any kind.
My 12/1 “s for instance:
I asked the Lovson people and they gave me 1.9-2 mm head clearance  which I think is a lot.
They claim .10 - .13 mm big end clearance -
they give no info on head torque - which on a 12/1 with it“s larger bore should be higher than the 6/1 c“s !
Neither for big end torque.

Who knows for shure and where can I read it ?


thanks a lot
Rolf

btw I have built some electric starters on both 6/1 and 12/1 engines.
Ford Transit Van starter motor with fits the standard indian krank gear plates and turns even  a 12/1 cold start without the decompression device as long as you have a good 120 Ah battery.
The 6/1 is easy on a Nissan Vanette starter motor and also with a flexplate from a GM 4.2 l V6 engine.
The flexplate adapts fine to the crankshaft by help of a 1 mm sheet sleave .
I drilled thru the original fastening holes of the plate into the flywheels and tapped with 12 mm thread.

I also made a mask for a standard 54 mm steel pot saw for a slow power tool to mill a hole into the head to fit a standard thermostat and a standard Ford Fiesta thermostat housing .
The holes of the housing“s flange have just the right distance for the water outlet studs.
