1450 Hytran and filter change

timbo2 · #1 05-03-2013, 06:33 PM

Hello all -

Finally changed the Hytran and filter in my 1450 that I got a year ago and just got running this winter.

I'm pretty sure I drained the original fluid(1976), the gasket had yellow paint around the edge and nothing wanted to come off without serious negotiation(rear plate, filter)

** One question I wish I asked before I finished:

Do you PRE-OIL the rear plate gasket when you re-install? I know you oil the filter gasket but wondered about the rear plate.

Some before and after pics.
Thanks!!

I clean them with brake clean then a little silicone on both sides of the gasket. Just a thin film will do it.

Thanks Sam-

yeah I used alot of carb/brake cleaner and wire brush to get the old gasket off. soaked then scraped about a dozen or so times on both the hydro case and rear plate. Thank God I had those wire brushes that fit on 12v drill. went alot quicker vs. scraper.

so far so good but I'll remember the silicon next time or if this leaks and I have to re-do it.

take care,

My preference is to hi-tack both side of the gasket and clamp it down. No matter what I've done with that process, it's never leaked, but silicone has failed me...

I'm such a believer in that method that my vehicles that came from the factory with "gasket maker" seals get cork gaskets at fluid changes...

In regard to a drill w/wire brush... Get an angle grinder and a wire brush for it. It's a SHOCKING difference in efficiency!!!

Max what is hi-tack? not familiar with it but will google it.

Good idea on the angle grinder, I have one but I not the wire brush attachment. will keep an eye out.

Permatex and NAPA brand are also excellent.

Man... You won't believe with a decent angle grinder can do with a wire cup!!! My cup is a Hitachi brand and my wheel is a DeWalt brand.. Both purchased at Lowe's for about $15/ea.... You'll never chuck a wire brush in a drill again!

Here are representations of what I'm talking about that I'm sure will work fabulously...

Thanks guys,

good info. I ran it for a while and checked a couple more times, no leaks but I'll for sure treat that gasket on my next one.

Be careful with these.... They will remove the metal too and then your surface won't be flat and won't seal.... Seen it too many times. On a rear diff cover it's not as critical as say, a cylinder head.. or anything aluminum.

This is a MUCH better tool. Aggressive, but the roloc discs are made of a hard rubber. They will remove metal, but you have to work REALLY hard at it. You can buy any die grinder you want... they aren't expensive. The discs you can get from most parts stores. They are a little pricey but if you use them right you don't wear them out very often.
