Well after fixing the intake problem on my SS/16 yesterday, Finally got that buggy running good again. I started working on the 19.9 that i originaly planned on before. I did some adjusting on the engine and changed the oil. I started her up and let the oil circulate for a bit. I got down the drive about half way when all of a sudden I noticed my left boot was covered in oil!:dunno: I was like, Here we go AGAIN!! So I shut it off, And looked underneath. It turns out the sump gasket blew out. So the very small oil leak it had when I got it has now turned into a very bad leak.:banghead3. So I pushed it back up the door yard into the shed. I was in a bad enough mood as it was, So I had no ambition to work on it yesterday. So I was ambitious enough this morning to start work on it. Took no time at all to get the motor off. I run into a couple of suprises in the process. It turns out that 32 years of oily greasy grass was clogging the cooling fins on the bottom of the oil pan. And check out the peice blown out of the right side of the head gasket! The inside of the engine is in really nice shape. No discoloration at all. The cylinders are mint, Even the piston skirts are flawless. Seems to be a keeper. Anyways, I ordered a new set of head gaskets and an oil pan gasket. I will post progress reports as I go. Enjoy the pics! - Brad

Here's some of the bottom end. Looks pretty clean and well cared for.

Well at least it gives you time to clean the frame up while your waiting for parts. I gotta replace a couple gaskets on my new '68. I like your SS 14 hydro, can you post a couple pics of it? Thanks

Yeah the frame is pretty greasy for sure. She'll be cleaned up before i reinstall the engine. I'll post some pics of the 14. - Brad

Yeah the engine runs super. Im kinda glad I got a chance to take the motor apart so I could inspect it. And so far im impressed. Congrats on the SS/16, I love mine. Its a '73 as well. Mine had fuel and intake problems when I first got it. But it runs great now after its little hissy fit two days ago. - Brad

That engines been apart once before!! the one rod has a #2 stamped on it and the cap! NONE of the onans ive ever opended have that on them...

I thought all connecting rods had some kind of proof marks? Maybe its something the B48G had? I like the idea of it being rebuilt. - Brad

Yeah it does look like a 220 doesn't it! Yeah I see that about the starter mounts. I guess thats one flaw they had. One I get the gaskets for it, I'll be able to listen to it for noises. Then I'll put the plow or blower on it to put a load on the engine. - Brad

Yeah definately Hugh! Hopefully the parts come soon, I can't wait to get it back together. - Brad

blower! plow doesnt do a thing for that motor as far as working it hard..... blower you'll get her grunting alittle but not much

my B48M 18 when I bought new rods and pistons for it werent even marked...and the old ones werent(what was left) and NONE of the BF engines ive had apart where, my franken P218 onan wasnt, and my P224 big block isnt either,and my NHC isnt(its got cast iron or steel rods instead of aluminum!) id bet urs has been rebuilt sometime in its life! is the piston labeled anything? all new pistons are labeled with their size(std. .010, .020 ect...)

 

[searstractorfan]

Ps, just realized!!! thats a P220 Onan, the 19.9 was supposed to have a B48G wasnt it? the P series is much better anyways!

Yeah your right, It was probably rebuilt a while ago. Back when part prices weren't rediculous. Thats cool that the NHC's had iron rods. The CCK's had them too didn't they? I hate aluminum rods, When I think of a heavy duty engine, I think of a cast iron block and steel rods. I'll check the pistons, I believe pistons are marked on the crown or inside the skirts. - Brad

No i don't think so. The ID tag says B48G on it. What gives you the idea of it being a P220?

the way the starter is mounted...the B series engiens the starter mounted to the oil pan on the back side of the motor, that starter is mounted to the block and in the front next to the grill isnt it?

Ah I figured that might have thrown you off! The B48G was the only engine on a suburban that had the starter mounted on the left side of the engine. If you don't mind me asking, Whats wrong with the B48G? When I hear people talk about them They seem to avoid them. I was reading a thread about someone finding a 19.9, But they ran from it when they found out it had the B48G. I do realize that everyone wants the N52M.
