Both machine using the same Gbx, an adaptation muss be available.

Simon,

use a 1ft of clear plastic tubing (windshield cleanner nozzle)

Push it over the oil nipple and maitain it with the hand (the oil pressure push it out)

d'ont forget to oil the back gear mechanism (2 points)

Hi joylon,

The ML7 manual say

640 Rpm ( 1"7/8 pulley & 1450 Rpm motor)

870 Rpm (2"1/2 pulley & 1450 Rpm motor)

1070 Rpm (2"1/2 pulley & 1750 Rpm motor/ 60hz)

This higher value is the max safe Rpm, old babbit bearing manual say

100 meter/minute (330ft) linear speed is max , with heat contol (hand touch)

The probleme is less modern lubricant than heat evacuation.

Certainly too much modication for the benefit

Kevin,

Scroll down to "Myford" then dowload :

1 _" Myford pignonnerie" an explanation of change gears for Series 7 lathes + ML10

2_"Myford ML4 manual" a succint manual for the ML4 with a threading chart a the end

For the set-up remove all gears, then start from the lead-screw, inserting a strip of copy

paper between the gear teeth (remove prior use).

hi kevin,

Have a look here: (ML7 apron IPC, similar to ML4)

http://www.myford.co.uk/acatalog/Myford_ML7_Apron_Assembly.html

The play is the play from the gears & rack assy, for precise move, use

top slide or lead screw & graduated hand wheel.

No idea for the gearbox installation (depend on your skill)

Hemingway kit is selling plans & kit for a ML7/S7/ML10 Gbx,

this plans contain certainly installation instructions

hi James,

An good explanation by david of the ML7 back-gear here:

http://iwr.ru.ac.za/~iwdf/lathe/backgear.html

The pulley is certainly sized by lack of lube,

another common problem is a separation of the pulley and is gear (press-fitted)

Further dismantling will requiring a Press
