Re: Perkins 4.108M DIY Rebuild -- A Narrative

Thanks for taking the time to do that for me PorFin. Did you use a dial caliper or a micrometer for the measurements?

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Por Fin, I appreciate that.

SloopJonB, I know, I was surprised too. They've got everything else but that.

Capnblu, I wanted to avoid turning the crankshaft because I didn't want to have to...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Ultimately, yes I am--either by it being explicitly specified in the manual or by subtracting the piston diameter (which is not in the manual) from the liner ID (which is there).

I can't find it...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

PorFin,

Where did you find the piston-to-liner clearance value for your engine? I've been over my manual twice with no luck...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

More info on oblique cut connecting rod caps:

Because of the large diameter of the crankpin to increase bearing area and decrease bearing load, the width of the bottom end of the con rod is...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

SJB,

I found the answer to your question on rrconnectingrods.com's website: "The angled rod cap is used on small bore engines or for camshaft clearance."

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Have you by chance had any dealings with either the Chinese or Indian arms of Caterpillar? Any idea where I might start poking around?

Re: Perkins 4.108M DIY Rebuild -- A Narrative

I certainly could do as you have suggested and install 0.010 inch undersize bearings and then "tune" the crankshaft to match the installed bearings by grinding and re-nitriding (Tufftride is the...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

I know that Perkins engines were used in a lot of different brands of equipment so they may have been the same!

Re: Perkins 4-108M Switch details

This is five years too late but what the heck...

Diesels do not require any electricity to run per se. On my Valiant (which has separate start and preheat switches) the ignition switch simply...

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Thanks for the kind words. I'm the new guy here and my reply kinda turned into a narrative of its own!

Re: Perkins 4.108M DIY Rebuild -- A Narrative

Re: Perkins 4.108M DIY Rebuild -- A Narrative

I wish I'd been around when you were rebuilding your engine. I am currently rebuilding a Perkins 4.107 and have found that the connecting rod IDs are out of limits. I'm trying to figure out what to...
