Clutch Dog Wear

[Paulywog0667]

The spring for my clutch dog broke. The reverse side seems to have gotten some wear, from lack of tension. Opinions on how a slight grinding would hold up?

Fix it correctly. JMO.

I found one online. Couldn't find the part number on the website.

That is some pretty severe wear on your dog. It would be reasonable to expect wear on the mating gear also. It is a waste of time and money to put a new dog against a worn gear.

What motor ?

What motor ?

A 1972 50hp. Johnson hydroelectric.

I bought the reverse gear awhile ago. There was a lot of crud and took it apart to debate grinding, clean and found the spring broke. I'm at a guess if the solenoids aren't pushing great or normal long wear for a 1972. I was debating since the reverse side is new, if grinding the clutch dog would last. Seemed silly a reverse gear for $25.00 and a clutch dog $40.00, but it's a 1972 and better than pretending I would pay $200.00ea..

To get reverse requires the highest oil pressure.----If there are problems with oil flow to the pump or water you will see that wear.-----And I guess that some still think that reverse is a braking system for a boat.----$ 40 for a better dog is cheap.

There was water in the gear unit. It cracked all around where one of the retaining rings were. That got welded, bought a new seal kit, forward, reverse, pinion, and clutch dog. Picked up a toggle switch and relays to shift from, control units pricing seem rediculous for being a toggle and two $1 relays. I haven't messed with the solenoids beyond they'll probably get through one more impeller at least or guessing if getting rid of the water and cleaning would resolve the problem.

That gear is as worn out as the dog is. You say you replaced it not long ago?

However with the added information (it's a hydro-electric) it might work anyway if you don't give it a lot of throttle in reverse. But only because hydraulic pressure holds it in reverse to the limit of its ability. It surly would be grinding and chattering if it was manual shift.

Your choice what you want to do with it.

I was getting opinions about why wouldn't a dremel work instead of buying new, but found a new one not at a boat payment price.

That has been done, with varying degree of success. Main problem is the hardened surface is gone and it is softer underneath.

Once I debated balance if grinded, even though a solid prop shaft, $40.00 seemed less hassle. If it was something that routine pulling of the carrier was standard, maybe. If $150.00 was the only option, I would have grinded and caught some fish before entertaining the price.

A reliable machine shop could easily clean up the gear lobes... worth a try.

The new clutch dog that now lists for $165,00.... Are you saying that you bought a new one for $40.00? (Your Post #6)

 

[Paulywog0667]

Some places had high pricing. $165.00 would be the most expensive I've seen. Not comparing, but how expensive do people think brake calipers and trailer hubs should be? Forward, pinion and reverse gears look more like a bit wear debate of cost than a clutch dog. Actually under $40.00 including shipping.

Well, you got one hellava deal, I'll tell you that. The seller actually sold it to you for the price of a good used one as used is normally figured "half of half the price of new" or roughly 75% off.

I still have a brand new one in my remaining stock... think I'll list it with some of my other stuff on eBay to see what it goes for.

 

[Paulywog0667]

Sometimes the local marine warehouse says $2.00 for a retaining ring and sometimes $20.00 for the same ring. They don't try to say one is worth more or cost them more.

There may be a day when spare parts for motors will not be available the way it was in the 1960's / 1970's.-----The cost of identifying / packaging / preserving / storing / retrieving from shelves / shipping is getting too expensive.-----That is why nuts and bolts for motors are around $10 instead of 19 cents in a bin at the hardware store.

 

[Paulywog0667]

I always buy $0.19 nuts and bolts at hardware stores instead of paying $10.00. O-rings at $0.05 without $8.50 in shipping too. I usually support specialty shops when feasible, but $150.00 for a clutch dog wouldn't have been one of those times. If it was shattered and only a $150.00 one left, I would buy another $200.00 1972 motor instead of $150.00 for the clutch dog.

 

[racerone]

But not everybody has the time and ability to do that.-----OMC / BRP / the dealer is not making a lot of money getting that one nut / bolt / ring to you for $10.00

 

[Paulywog0667]

I fully support if someone wants to charge/pay what they believe is reasonable. Sort of the same market with the $40.00 one not there though. Some are 20-40$ and some are $150.00.
