Asked this elsewhere, but. What's the best way to check the oil cable play on a 94 vmax 600, do you pull the cable taught (toward the oil pump) and meausure the distance, adjusting the adjuster and locking the nut? I read elsewhere that you check by looking at the "indexes ??" scribed on the oil pump...can anyone spell out the best procedure, my sled runs great, but a lot of "wetness" around the y-pipe and the plugs seem a little rich. When I initially checked the cable, it measured 1.25 inches, well above specs according to the service manual, but I'm not sure if I'm doing it correctly...thanks in advance.
 
I would like to know also. I have the same problem with my 94 Vmax 600. I was told it may be a oil pump that is bad. I did not want to buy a $165 oil pump if that is not the problem. Are there any other oil pump manufactureers out there? Not hijacking post.
 
Oil cable adjustment

Form what I understand, the measuerment istaken at the cable (free play) between the one cable end and the jamb nut(and adjusting nut next to it). The larger the gap (more free play) the leaner your oil pump will be. I believe Yamaha sends them out pretty rich ( as they do most of the time) and spec it to 22-23mm free play, but I keep mine around 25-26mm free play as per a post I read about this a while back. Hope this helps.

Thanks for the input, I'm glad you mentioned...I didn't know how the free play correlated to the oil amount..thanks for the info.
 
Ya...I tried the search, but I only found someone referring to the index marks on the pump, I wasn't sure if more free play or less would result in more/less oil...sorry for the duplicate post.
 
Just a quick follow up question, if the longer the gap the more oil...what would be recommended setting, I have a 94 vmax 600, heard the factory settings are too rich...any recommendations?
 
VMax oil pump

Longer gap equals LESS oil, the pump will be leaner. Shorter gap equals MORE oil, the pump will be richer. Follow the link below and it will tell you about bleeding and adjusting oil pump on your sled. About 3/4 of the way down the page is the info for the 94 Vmax 600 oil pump. This info was found in the Technical Pages section from the TY home page, so it is easily accessible.

Upon looking at the recommended Yamaha specs it says gap should be between 27-29mm (measured at point A in pic in post below mine. Thanks daman. You are da' man! hahaha), which means you can probably go further beyong that (29-31mm perhaps) being Yamaha always yields WAY on the side of caution. Maybe somebody else can chime in how far beyond 29mm you can/should go. But that is the Yamaha recommended setting, 27-29mm

Hmm.... all the old post must be gone.



anyway it's measured here;

but make shure your throttle end play is right first;

factory setting is 27-29mm i would try 31-32 to start with then go from there.

throttle end play should be 1.0-2.0 mm

Thanks...I have the service manual with the diagram you posted, thing is it doesn't explain how to take the meausrement, I loosened lock nut (1) and pulled back on the adjuster (2) towards the oil pump until the cable is taught, then I measure. Not to sound stupid, but I just want to make sure I'm measuring the cable the proper way. I assume if my technique is correct, I should look for a gap of around 31MM. Also, is there a quick way to tell if the oil pump is bad and going full rich?

yes there is an adjuster nut to loosen then turn the collar and measure
the gap.

not shure on the oil pump gone bad thing,but you would know it ,she would
use oil like no tommorrow!!
 
Sandmanmike1, motogrid.com has them for 138 + shipping, I've used them, very reliable.
 
I've tried adjusting mine and then I get this feeling like I do not know what I am doing so I leave it alone. Is there a surefire way to tell if it is bad. I haven't read anything about how to test one.

As far as i know there is no way of "TESTING" a pump to see if it's
bad, they just go to WOT when bad.

But i have have yet to have one fail,,our '94's pump has performed
excellent over the years.

After looking around at www.ronnies.com 94 Oil pump part number is 8ca-13100-00-00 is superceded by 8ca-13100-01-00 which is then superceded by 8cr-13100-01-00. From what they are saying is the oil pump from machines 94-99 500 and 600cc will fit. Is this true or is there a mistake at www.ronnies.com
 
On the 95 Vmax which is almost the same It says loosen lock nuts then with throttle wide open turn adjuster in or out to align mark on control lever with mark on pump boss. Tighten locknut.
 
There is a mark on mine. Mine looks just like 95 does in the techpages. Also I can use a pump up to 99 model except SRX's and some 700's
