Hi, can anyone tell me what the part is that is on a BMC 1.5 just to the right of the airfilter (the part with 2 x spade terminals) & if it needs a dial where can I obtain one from.
Thx in advance,

I would guess oil preasure send unit.If your oil preasure gauge works it could be an extra.Sometimes guys use a second one that turns on an alternator or acsesories.

Many thanks for the info Larry. I havn't got a "oil preasure" gauge, just a voltage gauge and temperature gauge hence the question. Then hopefully I can fit a oil gauge and would really like a speed gauge but havn't got a clue on where to purchase or how to fit either of them from scratch, so ANY help would be gratefully recieved. I have got the manual but it doesn't help.
Regards.

Based on the look of the mounting flange, angle to the block, proximity to the camshaft rather than the oil gallery, i'd say that it is a tachometer generator for a rpm gauge. Can you post a shot of the mounting style at the base of the unit?


Cheers

Hi Nobby, really hope your right that it is for a tachometer. I have attached another photo taken from a different engine but still the same unit?

Yep tach generator, that big nut is female to a male stub that sticks out from that 2 bolt flange. If you unscrew that nut the unit will come off and you'll see the the drive with a square hole or more normally a slot that correlates to the piece that slots in to transmit rotation to the generator.

Brill thx Nobby, just emailed A.S.A.P Supplies to see if they can source a tachometer & whatever else I might need in order to install a tachometer. Unless someone else can point me in the right direction?
Many thanks for all your help.
Regards,
Don...

Hi boating folk. The more I try to find my way,the more lost I get ---- I'm looking for a KELVIN P4R gearbox ---- or internal components, as I have killed my gearbox without even trying. It seems that gears with toothache is not a good deal, to make for happy boating.ANY help gratefully received!!! TA, Alex.

Referring to the above request for a Kelvin P4 gearbox. My gearbox is a 1;1 direct box --- not a reduction box as mentioned. Confusion reigned as I thought the "R" denoted "REVERSE" ---- but it's for "REDUCTION."
Regards, Alex.
