Impeller Shaft Loose V/P AQ 151C

[Ark-86]

I'm trying to solve an overheating issue on a "new" motor in an old boat I bought recently. It sure looks and sounds new, btw.

Got my new impeller (through iboats of course) and downloaded a manual. Looked like a simple swap....

1st thing I noticed was that the timing gear cover was broken and pushed away in 2 of the 3 place it is mounted. I removed the bottom allen screw and off came the cover. Looked like very new breaks in the white metal.

The old impeller looked perfect, except there was a lot of wiggle in the shaft. Pulled the whole works, and the little receptacle thing that drives the shaft fell out. (cross piece carrier et al?) There's a bolt in the center that hold that little assembly in place, and it was backed all the way out.
I thought of tightening it, but there seems to be a key or something missing from the back of the round metal piece that the cross piece carrier sits in, and the carrier itself is kinda bent inside. To my amateurish eyes, it looks like that bolt working it's way out caused the strain on the timing gear cover that broke it.

It would appear that if I put it back together, it will spin apart again, since there is nothing locking that receptacle arrangement in place. Yet I see no evidence of anything broken away, like a key. My manual is of no help here, and I can't find any similar threads here...

If anyone has seen this problem, or knows how that bolt normally stays in place, please let me know.

My children will thank you while I drag them through the frigid water!

Maybe post some pix, that would be of great help. I have the same set-up yet cannot follow what your problem is based on your explanation.

Have a great day

Rob.

Re: Impeller Shaft Loose V/P AQ 151C

Thanks for the replies. Bondo, you are right about the kids!

I have a picture from my manual that I moved to word and put an arrow on, but the "manage attachments' window won't let me upload it, says it's too large. To further complicate things, when I am at home in Canada, apparently I cannot open the Volvo links. Weird, since I just set up an acct and ordered a bunch of stuff while on vacation in Florida, with the same computer.

Not sure what to do now. I could email the pic if you want, Captmello.

The trick is to post your photos on a site like photobucket. Then link them to your post. There is some info on posting pics in the nonboating technical forum of Iboats. I also have had trouble with Iboats using Internet Explorer, I've been using Google Chrome lately, and it runs much better.

What manual and page number are you looking at?

Re: Impeller Shaft Loose V/P AQ 151C

I assume these are the parts you are referring to. If so, I think there is a boss on the back of the loose part that sets in a hole in the wheel. Pull it off and look is about all I can say.

Re: Impeller Shaft Loose V/P AQ 151C

You guys have no idea how much I appreciate you taking the time to help.

Don posted the perfect pic, and I have the loose part in my hand. There is a slot on the wheel that would line up with a dog or a key or..."boss"? on the back of the loose part, ("Carrier", says my manual), which houses the "cross piece carrier". Strangley, that boss must have disappeared without a trace, not even an indication it was ever there.

I guess I'll call Volvo in the AM and see if they can ship me a new one, along with a new timing gear cover.

Thanks again.

Item 26 - has a pin mounted into it(not apparent in pic). It appears they want to sell the complete unit. $132 rather pricey.

Item 21 "Bracket" VP# 855504 $200

These are very common parts and your best bet is to buy from a marine salvage yard. They are used on AQ151, 125's,131's and likely others.

I'll let others chime in with their preferred salvage yard.

Also ebay item # 350290831194 is for an AQ151 part(not what you need)but they are dismantling an AQ151 and may have what you're looking for. There is a phone # listed in the auction.

My guess is $50 should get this done.

Hope this helps,
MD

Re: Impeller Shaft Loose V/P AQ 151C

Thanks guys for the links.

Too bad I can't open the V/P ones 'cause I live in the frozen north....Even though I have an account with them and just bought stuff online while in Maine. They told me today I'm out of luck til I get back to the states. Will have to make a few calls instead. I'll find a deal on those parts somewhere.

The ebay angle sounds interesting. I can shop there no problem, same as Doug Russell and iboats aftermarket parts.

It's 37 degrees and blowing hard from the north right now here. The river looks like it can wait awhile.
