I just did the change over to all electric fans thos spring. I have two 16 pushers one on top of the other with an engine oil cooler in front with its own 10. Onthe pass side i have a trans cooler with a 10 puller. When everything runs they pull 26amps but ahhhh you can't hear anything! I went this route be use the clutched fan kept throwing the belt and the soild fan sounded like a convair 990 at takeoff. Ipulled a 4000# boat in 105 heat and never got over 210f. Its dark here now but ill post pics

I forgot to say you need to remove the fan shoud from the back side of the radiator that is the big trick to make the pushers work

One the discussion of oil selection and the 454, there is a VERY good thread onver on the Benzworld forum about additives and oils for older designed flat tappet engines... and the original poster is Ps2cho... my eldest son... the apple falls close to the tree it seems!
It seems that the best oils are Diesel engine oils...
Lots of great info there.

Good find.

Our 84 310 has the rubber sealing panel above the radiator and we don't have problems with running hot whether at idle or at speed.

The 345 I dismantled did not have the rubber sealing panel installed and it showed signs of over heating such as radiator core leaking and no thermostat installed.

I've already got the rubber to make the sealing panel for my Argosy. I do need to fabricate filler panels for the sides similar to the 310/345. I have the left side panel from the 345 to use as a starting point but there are enough differences that it will need modification. I'll worry about the right side when I get to it.

What rubber did you get to make the radiator panel?
Ours is MIA...

Pretty sure ours has the RH wheelarch panel, and like the LH, I plan to remove and paint it, so let me know if you need some dimensions!

I'm not sure which rubber sheet that I bought but this is the seller I bought from.

Rubber panel

Starting dimensions are always good!

Brad,
Further to the discussion about the engine side panels...
Did not get any sizes, but it looks like a simple flat sheet of steel on the passenger side.. no flanges, no contour at all.
I will pull it off soon and get you some dimensions, but I just gave the bolts a good douse of PB Blaster for this week.

Somehow, I was expecting it to be like the drivers side, but I guess that fits around the Hyydroboost unit..
FYI.., this pic was taken from the engine side of how it would be mounted... I think!

I need to compare the right hand side panels on the 310 to the ones I removed from the 345. I may already have what I need and didn't realize it

I vaguely remember removing one or two basically flat squarish panels from the right side of the 345. I'll look at the 310 in the morning.

Hi, all,

I don't participate too much in the MH stuff. It has been way too long to remember and I don't have access to all the OLD info I had when I was in Central Office. None of it made its way to our electronic database as we got out of that business some time back.
BUT one thing I remember is the above airflow info. IT IS CRITICAL. You will do yourself well to close out around the radiator and the wheel well. It is cheap and will cure many ills. I really don't remember if AS was a big(ger) issue than some other MH manufacturers, but with the age these are getting, I'd wager a lot of the units have missing or damaged closeout rubber.

As I recall the wheel well close outs are an even bigger issue than the radiator close outs.

Still no wrist-pin clips. Called them (Powerhouse) last Friday Didn't get in the mail till Monday to arrive Wednesday or Thursday. Now It's Friday and NO CLIPS. Ordered this November 12th. About ready to box this junk up and send it back. Called a couple places locally, "The clips come with the pistons." So, I call the makers of the pistons, 'Probe Industries' and they are going to mail me another set.
Now I guess I'll go take the wife shopping....NO ANYTHING BUT THAT!!!!

Thanks for the feedback. This might explain why our 310 never seems to have heat related issues. It has the rubber shroud up front and the wheel well guards in place as well. The 345 that I dismantled did have the wheel well guards but it didn't have the rubber shroud up front. I believe it had heat related issues, I say that because the radiator looked like it had suffered from heat and the engine did not have a thermostat installed which is usually a last ditch attempt to try and get an engine to run cooler.

Thanks!

Brad

It's amazing how the smallest thing can hold up progress. Hopefully you'll have the clips early next week.
