    303M HydraMatic rebuild

    Received the quote from "Gardico" gaskets today. They want $80.00 per kit. So for ten kits that's $800.00. I sent them a message asking if they will drop the number of kits to four. I'm sure I will not receive an answer until next Monday. Honestly that price is not that bad. That's only $10.00...

    303M HydraMatic rebuild

    Another interesting item about the "C" MWO and the newer rear servo was the "rear band actuating lever spring" was removed. So no more automatic rear band adjusting. Like I mentioned earlier, it never really worked well. I circled the "actuating lever" . You can see there is no more "spring"...

    303M HydraMatic rebuild

    I was thinking about problems rebuilding front pumps on the 303M transmission. Really there is only one and that is the lack of new "vanes" . The front seal is being repoped, the seal ring is being remade as is the gasket and bushing. The housing is easily machined if there are any grooves in...

    303M HydraMatic rebuild

    I know "Fatsco" sells a bushing kit. I think they sell the thrust-washers on a need basis. As far as a kit for the front pump goes, that might be diffucult. I haven't seen the vanes for sell for several years now. We might be able to use vanes from another manufacturers pump. The front seal is...

    303M HydraMatic rebuild

    I talked with the people at "Gardico" gasket manufacturing today. We settled on a material to use. It has a 1700 PSI rating and a 700 degree temperature rating. It is also partially reusable. Meaning parts can be taken off and the gasket reused if it has not torn. They are getting back to me...

    303M HydraMatic rebuild

    That transmission should clean up nicely. The output carrier looks good too. No. I only have the MWO for the "C" modifications. I don't see them changing things much though. There was a change in the rear servo though. They went to the newer style with the "exhaust valve" built in. This valve...

    303M HydraMatic rebuild

    In that new 303M information manual I just got, it mentions all the specifications of the transmission including the spring pressure on the "Reduction Accumulator" . Remember I told you to leave it alone if the springs where not broken, well here's the reason why I said that. The smaller inside...

    303M HydraMatic rebuild

    I forgot to mention. We have tons of Blackberries out here. Grow wild everywhere. A real nuisance plant actually. They only ripen in late August early September though. We will also have plenty of Blueberries this year. They should start ripening late July.

    303M HydraMatic rebuild

    As per our PM message, this should be a real interesting trip ! My injections went well, so I should be in less pain and able to withstand a long trip like this.

    303M HydraMatic rebuild

    Once you bust up that housing (it is a real pain, that cast iron does not like to break ! ) and remove all those fun little bolts, the transmission slides out like butter. Then your left looking at that poor housing you had to destroy and cleaning up all that spilled transmission fluid. Oh...

    303M HydraMatic rebuild

    Sorry no. You need the "C" MWO applied for that. Yours was probably still in good condition so they left it in. I was thinking about why they (the military powers that be) decided to finally use this servo. I believe it was because the old style parts had dried up since all the civilian...

    While i've been away..

    Duuane loaded up my truck with the 303M I bought from him with this beasty. I asked him at the time if he wanted to sell it. He just laughed. :cry:

    Hey Duuane, are you moving all your stuff from the Vancouver house to your main home ?

    303M HydraMatic rebuild

    Any HydraMatic from 1953 on will have this servo. I am at the clinic waiting for my procedure and thought I would check in.

    303M HydraMatic rebuild

    So Thursday I'm going in for a "Spinal Nerve Root Block Injection" . This will lay me up for a day or two. Also, my wife has been after me to finish the Gazebo in the backyard. I need to finish the roof panels. That should take a few days. So, this week and a bit of the next week I won't get...

    303M HydraMatic rebuild

    Before I start on the rear servo rebuild, I have some really interesting news. As many of you know I collect Military manuals. All types, but especially ones with Automatic transmissions in them. Well I just bought another copy of the "TM 9-8025-2" ( an original June 1957) which makes four...

    303M HydraMatic rebuild

    Hey, are you really attached to that main case ? I could use one as one of mine has that nasty crack in it.

    303M HydraMatic rebuild

    OK, here's an update on that front servo mod. Yes this 1953 servo will fit and work just fine in our 303M transmission. So if you want extra braking power going down hills than get yourself this servo. I found two more in my pile of parts. One I had thrown in the metal recycle bin. Saw it and...

    303M HydraMatic rebuild

    Hey plowboy, you out there today? I was looking at the main housing end gasket in the kit you sent me. This gasket will fit either the 301MG or the 303M transmission. That tells me there was probably a "supplemental" gasket kit made for use on the 303M transmission. So instead of looking for a...

    303M HydraMatic rebuild

    Well you should get some credit as you sold me one of those 303M transmissions. :) Now If I could only find a few more. Do you have any leads ?
