I'm honestly not sure. I'd prefer to fix it before using them, that's for sure. Shouldn't be a big deal if it's just a thrust washer - I've pulled these pumps apart and it's not hard. You don't really have calibration to worry about except in certain places, and just measuring length of screw / counting turns is 'good enough' when you are talking about a beater pump that's beyond it's warranty period in any case.how long you have some running this way?..im thinking about stowing this one away for rainy day in case it well...rains..when you say changes timing, is it considerably and i wonder what are the repercussions of running it that way? seems creepy
I honestly didn't notice/realize the whole in-out play until a few months ago - When I bought big red(93 in avatar), it ran fine(advanced a bit when I got it; retarded it on the way home and she ran good). A few months after that, when I started to leak coolant from the head gasket, I figured "Eh, needs more power anyway. What's the harm?" and swapped on my RD2-110 IP, put the original IP aside as a 'known good'.
Cut to a couple months ago, when I'd just built a motor for my '88(block from big red - that got a running 7.3 IDIT instead of just a head gasket swap), and decided I needed my RD2-110 for the '88. So I pull it off Big Red, and need an IP. I pull out the 'known good' IP, install it... and notice it has a bunch of in/out play... I got it running, but then got concerned and decided /not/ to use it. So I search through my IP pile and find several IPs... all doing the exact same thing. I found one that didn't do it(actually the one that came with the running 7.3 IDIT) and used that instead.
So, I'm not currently running(that I know of) a loose IP, at least in my DD. I'll have to check my other vehicles, and /have/ to learn how to fix it, because my 3-4 year old RD2-110... is doing the same thing! That's too expensive to give up on, when it has less than 30K on it(and still works fine, though I wondered why I'd get a puff of white/blue smoke on deceleration).
Once I tear into one and figure out what part needs replacement, I'll probably buy a half-dozen; got a stack of pumps that otherwise would be perfect.
Worst case, I might have to do something silly like make a custom IP-gear-cover front place that contains a thrust bushing of some sort and just push in on the shaft that way. Hey, if it works...
