Can anyone shed some light on part numbers for this engine? My parts I want to order all start with 201 but im finding when I search for them online they start with 570.
I.E.
My piston: 201-50851/OS 020/19 (assume thats 020 oversize)   Internet piston: 570-10940/020
My Big end bearings: 201-50971       On the internet : 570-12170

Any help would be appreciated. Thanks

Hi Hes

first of all: strip every part, clean thoroughly every part (some pics wil help when reassembly), mesure main parts (bore, piston, rings, journals, babits, bushes, etc).

After that - only - you will see IF you need some parts. Dont expect to have a Ferrari!

You seems to be hurried!

Be safe

PS: tilt pics and resize pics, and tilt and cut.

Had a good clean of everything today. This engine was stood full of water for a long time and was seized tight.

Cylinder is pitted heavily, piston is scored, valves are like a sieve, push rods are bent, big end shells worn through, mains worn through.

All parts il have to renew, probably a few more yet aswell.
