Bracket, ALT Broke!

Was changing out my belts and notice the alternator bracket was broken! Where do you find one of these? Have one local marina looking. Any input would be appreciated! Thanks

That's a common problem with that bracket, someone over tightened it. When you do find a new one use a washer to take up any extra space between the alternator and the bracket or you'll snap it again. Ask me how I know.

Thanks guys! Weather is getting better and WAS trying to finally de-winterize the boat.

[/QUOTE]Art, if you could tell by the pictures, is it a bracket alt. LH or RH? After looking, R090055 is a LH alt. bracket but there are other options such as R090055A (says to use R090055C), R090055B (says to use R090055) and R090055C is a RH alt. bracket. [/QUOTE]

Wow, now you're teaching me something! I never realized that there was any difference between a RH and a LH alt bracket. The LH/RH has no reference to where the alternator is located, but rather the rotation of the engine. I have in my shop a 2001 LH rotation 351, and it has an 055 bracket on it, just like yours. I looked in the PCM price list, and it reads just as you quoted. What reference did you look in?

I am currently looking in my 1980's PCM parts reference manual, and now I have found out that part of the difference comes in with which alternator you have; a Prestolite or a Motorola. Here is the quote from the book:
R090055   Prestolite LH
    055A Prestolite RH
    055B Motorola LH
    055C Motorola RH

Looking at some of the other parts, it reveals that the difference is in the mounting bolt sizes for the long alternator mounting bolt. Prestolite uses a 7/16" bolt, while the Motorola uses a 3/8". Since you have the 055, that tells me that you have a Prestolite alt, but that still doesn't sort out the LH/RH question. Check the hole size in your alt, in case some PO has switched it out without changing the bracket.   

My advice now is to call SkiDim (Discount Inboard Marine) at 803-345-0996. Richard will probably answer the phone, and he is extermely knowlegeable about the parts, so consult with either him or Vince if he happens to answer.

Something is wierd here, because you have a RH engine (I assume) and I have a LH with the same brackets on them. SkiDim will sort it out for us. They will probably be very busy on Monday morning, so if you get put off, give them a chance! Please let me know what you find out.

Hey Art, that's what's great about this site, always will learn something new!

My reference was from Pleasurecraft Engine Group Retail Price List 02/01/13 Engine Parts, pic below.



I was able to confirm that I do have a Leece Neville, manufactured by Prestolight, model #8RG2062. Now I took a wrench to the bolts and the ones that mount to the engine block is 1/2". The one that mounts to the bracket arm to allow the alternator to pivot is 9/16".

Now, I did send SkiDim an email with all the pictures I posted here and they should get back to me, but of course I will follow through tomorrow morning. Once I hear back, I will let you know what they say. Thanks for your input and findings as well!

Jody, will let you know about the used one you have. I personally would like to buy a new one but if that fails, I will be contacting you. Thanks for letting me know you do have one available! Have a good one.

Hi Art, you are correct, I was referring to the bolt head size and I do not have any bushings on the alt.

I did speak with Richard from skidims and they do have the part He did mention the difference of RH vs LH alt brackets. Typically CC uses RH brackets but the LH could be retrofitted. There is a bump on the LH brackets, did not say where, that could be grind off in order to make it work for a RH application. He also said that next to the p/n it will have a "C" which mine does right below the p/n "CR1" (I overlooked it and had to trace it out for clarification) which would indicate RH bracket. So if it only had the p/n R090055, it would be a LH bracket.

Fun stuff! Thanks for your help!

Hey Art, wanted to give you guys an update, received the part today from skidim and it fit like a glove Below is a side by side of the parts.

After that was fixed, I notice my fuel gauge was not responding, after looking into it, will be needing a new fuel tank sender

Thanks Pete! Took your advise before starting the boat for the first time this season. Turned over on the second try!
