Junior Whitehead thicknesser/planer PTJ Mk2 Help!

Postby steveindar » Tue Jan 30, 2018 8:14 am

Hi All, Firstly as intro I run an engineering maintenance contract at a tea estate in the hills of Tanzania. I am no woodworker but as part of our maintenance contract we have inherited a woodworking shop with some very old machinery.
If I could be so forward as to ask help locating an operating manual and repairs and maintenance manual for the above machine.
I also need assistance identifying what type of starter is needed, star/delta, DOL, two speed??
The full details are
Motor Type & No. G78161/481181
Machine No. W3503
Type. PTJ Mk2

Any assistance would be appreciated. I can post pics for those who like to perv the old stuff.

:D

There should be another plate somewhere on the motor giving electrical parameters without which it is difficult to know the type of starter needed. If all six terminals are connected to six wires going where a starter would have been then it will be a star delta motor. If the six terminals have straps fitted between them then a dol starter is likely. Motors rated at 5 hp or more are usually star delta.
If there are no clues. Wire in star and fire it up. If it seems significantly under powered eg by a factor 3 then try it with a star delta starter.

Many thanks Bob, I'll have the sparky scratch around.
