Re: Perkins 4.108M DIY Rebuild -- A Narrative

I've said it before, but I'm totally amazed at your ability to stop and take the time to document this all with pictures.. and your explanations are succinct and easy to follow. It's great, and this thread should be bookmarked by any Perkins owners out there.

Thanks again, Porf (or should we say Prof )

Medsailor. That was not fun. Porfin has been a real sport in sharing with us all that great work.

For your information, mabey Porfin looks like this ! Ok, that would explain why I invited Porfin to help me with my engine ;-)

Med, you got the pics out of order

Before starting (notice the younger man, covered in grease and oil, and smiling in compete ignorance):




After completion (a much older man, no longer amused, but confident in his knowledge of the subject matter):

Re: Perkins 4.108M DIY Rebuild -- A Narrative

PorFin,

I am in Martinique on my sailboat and have looked through the various printed manuals that came with the Perkins 4.108.

There is a "Core and option parts book" that may be the one your are looking for !

It is the Perkins engines North America version 4.108 M

It has a "part number" : NAP000265 PB, Issue 1, October 1981.

It has almost 100 pages.

I seems to be exactly the proper one for my Perkins 4.108 M (1989) with one exception : the heat exchanger is slightly different, it is the one you find on the "low line" 4.108 engines. The shop manual that came with it is the 1983 version, which shows the proper engine on the cover (with the Bowman heat exchanger) but does not show anything about the exchanger in it!!

I guess they may never have made a part manual for the public !?

Anyhow, with that "one and only" diagram of the Bowman I posted earlier it is pretty complete.

If that is the manual you are looking for, I can bring it back to Montreal (in about a week) and scan it for you. I know it is a little late, but it is now that I come visit my boat.

Jacques

PorFin, is everything OK? I forget, are you still waiting on some parts? Don't tell me it's all over!

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Ahoy. folks.

First, let me extend my sincere apologies to those whom I've left in the lurch -- I should have let everyone know that I was dropping off the net for a little while.

Bottom Line: I will conclude this story complete with (ahem...) cost data, so don't give up hope.

Here's the deal: Now that we're dirt dwellers once again and the weather started to warm a bit, I began to tackle a few "simple homeowner maintenance chores." As a somewhat conscientious older boat owner, I should have known that those words in the quotation marks rarely go together.

I discovered a small leak at our front door. I grabbed a tube of caulk and a putty knife, and figured it'd be a 15 minute fix.

Boy, was I wrong.

As I was digging out the old caulk, I noticed the jamb was soft. Doing some exploratory surgery with the putty knife, I soon realized that painters over the years (while I had the house on the rental market) had applied PVC caps over what they had apparently also noticed as soft wood. All this did was trap water in the wood, and to make a long story short, I've got a new prehung door with sidelights on order.

If the pain ended there, it wouldn't be so bad.

The water that was coming down the wood fibers of the jamb also rotted out the sub sill (another WTF discovery -- the builders used 3/4 OSB on the concrete slab to elevate the door sill to clear the oak flooring; who in their right mind would have used OSB?)

The mission creep continued. The hardwood floor adhesive was beginning to fail, so I tore the floor up in the foyer and am now prepping for porcelain tiles. Getting all the adhesive off the slab was way, WAY too similar to scraping bottom pant for my liking. I still need to hit the slab with a diamond cup to get the remnants off and to roughen up the surface so the thinset will bond well and I won't be faced with tiles popping up too soon.

So, once again, apologies extended and I promise to wrap this tale up once the home project gets put to bed.

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Glad to hear that you are still alive my friend.

I hope this whole description is about your house, not you boat ;-)

Had about the same experience last summer when I decided to replace the patio door, ended up redoing the whole wall, stripped down to the concrete foundation, changing all the windows and changing the flooring. Looks nice now.

Next project is the Perkins!

Looking forward to the rest of the Perkins story!

As a former door and window pro, I know your pain. Nothing does more damage to the doors and windows of a house than a painter on a budget.

It's 5 o'clock somewhere:
