It's not that difficult to do, just follow schematic, and pay attention
to where the parts came from.

Cheers AJB,the diagram is really helpful.what tools will I need to get the pump head off and split it?
                                           regards Jeff.

Spanners for the hoses, not sure but 3/4" seem to ring a bell,
a set of imperial allen keys, again not sure which size off hand
possibly 7/32".
a flat bladed screwdriver to drift the bearing loose on the thread,
and a hammer to tap the screwdriver with.
What symptoms are you getting with the pump.

[jeff1966]

The pump running fine at the moment but its been about 11 months since it was last serviced,just planning ahead.How often do you service yours?Amtech recomend every 6 months.
                                cheers  Jeff

Amtech recommend every 480 hours.
mine did 2500 hours or thereabouts before problems.
Personally if the pump is running fine, and not dropping
pressure or very noisy, i wouldn't bother. If it's just noisy
replace the bearing.

I more or less agree with AJB's approach above.

But there is one thing I still do even if the pump is running fine. At 12 months, or before if I have to open the case up, I will simply remove the pump head and apply some grease to the bearing. It's just 4 allen bolts and any other items you need to remove to gain access.  In my machine I just remove 1 vac motor (1 screw) and the pump mounting. I don't even need to disconnect any hoses.

Safe and happy cleaning
The Ken
