Hi John,
I get my blower and pump oils direct from woodbridge.
Water pump is dead easy.
Drain from pipe, refill to half way up glass site.
Blower is a bit fiddley, but i managed.
Drain plug on bottom.
Level plug on side.
Filling plug on top.
Drain oil.
Fill it up untill it comes out of the level plug on side.
I use a small oil can, with a flexible pipe, to put the oil in. It doesnt hold much
At 500 hrs I would also change spark plugs, fuel filter, air filter.
Its not a major job, only needs to be done once a year.
regards
Chris
ps
£330 + vat for your water pump
I thought it was just the 12 volt fresh water supply pump ?
Flojet or shruflow ?
