420 crawler 1957

[kevencyr]

anyone would know where i could get an engine for my 420 crawler, 113ci liquid cool. thanks

We have a few but a fair drive to get them. If your is salvageable, they are fairly easy to rebuild and the parts are reasonable.

I just did my 420 engine. I had to go 40 over and have my crank down. Did save on pistons as we had a real good set of used on hand. It was the first engine I assembled by myself and runs great. Waiting on some items from Lavoy to finish it and I will post some pictures.

thanks, i think mine is in really bad shape, got a broken piston, my 2 cylinder have a noticeable edge at the top, can't get my piston to get out from top, rings get stuck on that edge. notice some damage where connecting rod connect to crankshaft, that what i;m saw so far. regretting paying to get my cylinder head done last summer. that why i;m trying to find an engine.

Keep in mind, nothing says the used engine you get is any better than the used engine you have now. Engine parts are readily available, why not rebuild yours.

X2 LAVOY plus he already has a rebuilt head AS for getting the pistons out you might have to get a ridge reamer or at least take a hone with the piston at the bottom an knock some of the ridge down

anyone knows where i could get new sleeves for a 113 engine, did some research around here and none. got 3 good piston, like i said, i got a pretty big ridge, so i probably need new sleeves.

[Lavoy]

It is not a sleeved engine, so no specific sleeve for it, machine shop just orders by bore and height and machines to fit. Can't it be bored for oversize? Sleeving is a double bore and decking, plus the cost of the sleeves, way cheaper just to go oversize.

if i go oversize, i would need to get 2 new piston right?, that what i was trying to avoid. the person i talk to in canada told me it would cost me over a 1000$ in parts if i needed everything. was trying to keep my 2 original piston. can i just remover the ridge and put new rings?

[Stan Disbrow]

Hi,

Bores wear in an egg shape across the bore, and in an hourglass shape along the stroke. The only way to true the cylinder is to bore it.

So, no. There is no reusing the original pistons. There are usually two oversizes for replacement pistons, with the idea that you can bore twice for rebuilds before the block is junked.

When blocks become scarce, then sleeves can be had. But, as Lavoy pointed out, using those gets even more expensive. There is more machine shop time required. Even then, they don't always wind up using the original piston size.

With your having such a ridge at the top, that tells me your bores are quite worn at this point. You might have the original size pistons yet have so much wear you have to jump over the first oversize and go to the second to get it true again....

ok, thanks, then i might have to wait until canadian money and us get closer, right now its a crazy difference from american to canadian money. where would be the best place to check for a overhauled kit.

[jtrichard]

HI Stan i found 3 oversizes .045..090 and .125 and looks like the parts are in the $700 to $800 range

[Lavoy]

If you use your old pistons, it will still cost the same money as you have the cost of the sleeves, the cost of boring the block, installing the sleeves, decking the block, and boring the sleeves. When you are done, you have a nice square bore with two old worn out pistons in it, all in all, a waste of time.
As to the overhaul kit, again maybe I sound like a whiny 3rd grade girl, but me selling parts pays for the website you are on for free asking where to buy parts.
The oversizes JT mentioned are normally readily available, I have sold and used more sets than I can count.

thanks lavoy, so next step to be able to get a kit from you would be to find out what would be the cylinder oversize, probably the same thing for my crank and cam i assume. and also the prize range would be around 1000 canadian right
