one that i think  "ace" might be interested in


a few weeks ago a oil pump spindle failed , first signs were the semrat rockers locking up , (as i was proceding at speed)

knowing this problem might happen again , i decided to do something?

now we all know that the bullet has low oil pressure , but a good flow , so a guage was out of the question.

I decided to fit a very low actuating oil pressure switch into the quill bolt.

the switch actuates between 1.1 and 2 LBi , (so is low)

I set this up , on a space on the cascette reseved for a warning light , that shows when my side stand is down (no cuttout fitted)


switch here http://cgi.ebay.co.uk/NISSAN-MICRA-BLUEBIRD-OIL-PRESSURE-SWITCH_W0QQitemZ220506484619QQcmdZViewItemQQimsxq20091126?IMSfp=TL091126206005r11527


i removed the plastic section , and its descrete , if for some reason the light comes on ,,,,,,stop!!!

[chumma7]

very good idea. got any pics of this installed?

[enfield freddy]

the switch supplied was an "intermotor" brand

51150 24 1/8" BSP Taper 0.7-2.2 LBS

and it was a simple job to put a spare quill bolt in a lathe to be drilled/tapped

only one wire was needed to be run to the cascette

It's a neat idea.

Are you running the floating bush or the roller?

I don't think the roller will hold any pressure.

[enfield freddy]

at present the standard big end , the switch has such a low operating pressure , i think it would work on the later roller type

as the cost is just an old quill bolt , a (£5 UK) switch , nothing is lost

if/when the light comes on STOP!!!!

Freddy, that is an excellent idea. I'm with chumma7, would love to see pictures and some directions. Thanks. cochi

parts are being manufactured at the moment for a mk 2 version, the idea is to make a semi hollow bolt , to replace the oil filter bolt , this new bolt will have a tapping on the back to take a switch , with a drilling running down it for several inches , then cross drillings to get the pressure from the filter housing , we are trying to find the correct dia /material that will not break on the cross drillings

this one will  sit neatly , where the nut at the back of your filter is now

[cochi]

Freddy, that's even a better idea. Keep us posted. I'm, for one, am very interested.       Thanks, cochi

I am having several sample made up (as we speak) the cost of the final article complete with a compatable UK made switch should not be excessive , the idea is to make the thing foolproof , reliable , unbreakable , and a cost effective upgrade.

when they are running , i will send photo,s/samples to kevin and let him decide if he wants to supply , if not i will make then available vie paypal

Freddy I'm a bit confused you say the nut at the back of the filter. The Bullet doesn't have a nut at the back. All the 700s I have do but the bullet I own doesn't. Is this just for the twins?  ERC

Thats a good idea the only one I ever thought of was with the Quill bolt. Actually CMW had a rig like this with the Quill bolt years ago but they discontinued it.  Must admit I never thought of trying to use the through bolt on the twin oil pumps.   ERC

cheers have tried on the quill , tapping in and fitting a switch ,, a guage is useless!!! but the switch works ok,

but it looks ugly , and in the case of my bike , is very close to the sweptback front pipe.

the prioity is finding a sutable metal that in a smaller size , ie: closer to 8mm that will not snap/stretch when cross drilling are made into it , along with the drilling running down the interior to feed the switch outlet when you tighten the oil filter cover nut

things are looking good tho,

I wonder if you might be better in putting a tapped hole for your switch in a capnut that is then used to lock your standard undrilled quill bolt. You could cut in an oring groove on the sealing/ mating face of the capnut so that oild could come up the threads into the capnut and switch without having to weaken the bolt...

[enfield freddy]

sorry , late in the uk , bedtime almost!

plan 1 was to drill the quill bolt that screws into the timing cover , that feeds the cork/neoprene seal at the end of the crank? , this has been done , and we have proved that a oil light works , but a guage is a no no.

plan 2 , which is progressing , is to fit a switch at the rear of the oil filter housing , between the housing and the g/box ,and will get a reading from inside the oil filter chamber, sorry if i have misread your post (polish lager!)

Sorry, my mistake I thought you were calling the bolt that rod that passes through the oil filter the quill bolt.
