so i got a nvg149 off a member of the form and busted it open 2 install the new oil pump clip. to find that there were metal shavins n the pick up tube and bout a half inch of metal on the mag. found out that the shavings were from just normal were and the plantery gear was bad. but my question is there was also sum black rubber/plastic lookin material n there also. looks like splines of sum sort. could this b the material out of the vicous coupler? if any one has buisted one open and saw this let me kno what u did. do i run the viscous coupler or get a new one? any help would be amazin thanx

 

A lot of the time the rubberized material you’re describing is actually the sealant the factory uses to seal the case halves. You would think they would do a little cleaner job; however a lot of people describe finding the same issue upon disassembly. As far as the viscous coupler, it’s a sealed unit, so nothing should be coming from it. It is a non-serviceable unit and if it were to go bad, the only course of action is replacement. Sonnax also has an item that is probably more fool proof in protecting the housing from the oil-pump than the factory pieces, however I'm sure it also costs quite a bit more.

Sonnax addresses the problem by replacing the steel clips with plastic clips and also includes a screwed on wear plate to keep the aluminum pump body from making direct contact to the case.

ya i got the sonnax kit thats y i busted the case open and 2 check the chain and were on everything. we also thot it mite b the sealent the factory uses but y would it look like splines. and if it was sealent it wouldnt b alot rite?

 

I can’t say why it looks like it does, especially not seeing it, but some people have found there is so much of the crap in the oil pump pick-up screen that you would wonder how it didn’t starve of oil from the get-go.

 

wow thats just crazy. thanx anyone else kno anything bout this

 

If found the same type of rubber stuff when I took apart my np261...

 

did u just clean it up and use it or what

 

yea, just cleaned the gunk off

 

my olny concern is the coupler cuz they cost as much as a case.lol
