Oil Light on 83 GL1100

Post by peterlong916 » Sat Jun 01, 2019 11:19 am



Hi all, first time poster here.
My oil light came on today whilst riding and shortly after engine stalled with a sqeak (metallic type :cry: )

Only changed oil and filter 30 miles before 10w-40 (fully syn) and levels were spot on.

The oil level in window was low but engine started again, no noise, ran fine (I was 200yrds from home).
I've changed oil (10w-40 part syn) and filter again and checked oil screen which was clean.

Engine runs fine (on stand), light still on.

Q1. Ive got through a lot of oil since oil change, was it because it was fully synthetic?

Q2 I'm going to manually check oil pressure and was looking for guide on how to, any help would be appreciated

Q3. If there was a blockage, which has since cleared (no thanks to me), how long does oil pressure take to build up? I have only run engine for less than 10s but would have thought it would sort itself out in that time?

Any help welcomed!

Hi Peter,

you can check the oil pressure switch,
maybe this is the reason?
In the link below, there is a nice photo of where the oil pressure switch is located.
There is also explanation to test this switch.

Checked oil pressure manually today - 0psi :(

Checked pressure switch wire and functions as expected

Going to check water pump impeller tomorrow to check for oil pump function

I've come across oil pressure release valve/spring - anyone got any experience with these causing problems?

Hi Peter,

before you check the pressure relief valve of the oil pump,
it might be better to first check the case oil strainer.
This filter is located at the bottom, right in the crankcase.
You will have to disassemble the right exhaust pipe, at least the exhaust bends, to be able to disassemble and clean this filter.
If this filter is clogged, this can cause oil pressure problems.

Greetings,

Danny

Yes did that on the first day, it was clean. Fun getting it out though!

Probably nothing wrong with the oil pump. The problem is more likely to be the chain that drives the pump in the rear. If the engine survives unscathed it is a great testament to how tough these things are.

Hi Peter,

it will be a reasonable job to dismantle the water pump,
viewtopic.php?f=11&t=275
but, if it is disassembled, you can turn the engine around and thus see and / or feel whether the shaft of the oil pump is turning.
If you turn the engine (manually) you can carefully try to stop this shaft,
if this is not possible, it is not the shaft of the oil pump and / or the drive chain.
If the water pump has been dismantled you can check it.
The main oil pump can now be dismantled by loosening the three mounting bolts.
You can pull them gently out of the block.
If it is the clutch coil pump or its drive,
I think you will have to remove the block from the frame.

Greetings

Danny
