WTB Front Bearing retianer sm420
 

I need a front Bearing retainer off a SM420 manual transmission. Retainer is 4 11/16 inches four bolt cover for input shaft on transmission.

Re: WTB Front Bearing retianer sm420
 

I may have a spare in my stash of parts in the parts shed. Will look tomorrow and do some measuring. Do you have any numbers that may help? I know I have a bearing retainer but not sure what it came from.

Re: WTB Front Bearing retianer sm420
 

I cant get any #'s without pulling the trans. I know the retainer is 4 11/16 inches. 4 bolt holes around it

This is novacks billit design Attachment 881491


And this is what it looks like on the trans Attachment 881490. I dont know much else. I think mine may be cracked as it is leaking 80/90 out the front pretty bad, either that or the seal is bad. I would like to have both seal and retainer when I pull the trans out so I can just fix it and put it back together.

Thanks

Erik

Sorry but can't help you on the bearing retainer. Think mine must be for the sm465 as it is a larger at 5 1/8" dia. with four bolt holes, "GM 12" cast into it with " 3920748" stamped on the edge. Sorry to get your hopes up.

Re: WTB Front Bearing retianer sm420
 

I may have one, I will check and let you know in a little while.

If 70Stovebolt can not help I have this http://67-72chevytrucks.com/vboard/s...d.php?t=480846 and I can measure it this evening. It was a 4 speed out of a 1967 C20 but I do not know what number it is.

Re: WTB Front Bearing retianer sm420
 

I don't have one. Todd, those parts look like they might be New Process pieces. What is the casting number on that front bearing retainer?

Re: WTB Front Bearing retianer sm420
 

I really do not know what the transmission is that I got the parts off of. The transmission case looks like it has a casting #C-95948 D. I need to clean the bearing retainer up and recheck but it looks like it has a casting #97127. I measure it out at 4 5/8" diameter. I found this web site http://www.novak-adapt.com/knowledge...on_gateway.htm and it states the New Process has an aluminum top cover and this one is cast iron. It also states the SM420 was used up to 1967 and the SM465 were used 1968 and newer. I will get it cleaned tomorrow and get better pictures. Thanks

Re: WTB Front Bearing retianer sm420
 

I looked at your other thread, and the pics look similar, but if you would could you post a pic of just the front retainer, front and back when you get it cleaned up? I think this is the piece, its supposed to be 4 11/16 so 4 5/8 is dang close. My trans is out of a 67 k20, I think the last year for the 420.

Re: WTB Front Bearing retianer sm420
 

I thank the rest of you for looking, I appreciate the effort.

Re: WTB Front Bearing retianer sm420
 

Sucks man. I just took a SM420 for scrap a week ago. No one wanted it.

Re: WTB Front Bearing retianer sm420
 

Thats just the luck I have. My buddy had one in his jeep that he put in the scrap pile at work about 6 months ago. I keep kicking myself for not getting it. 3rd gear was shot but the rest was good, I didnt even think about getting it for spares. Live and learn I guess.

Re: WTB Front Bearing retianer sm420
 

Here are some pictures. There are pictures in post 5 of the thread that shows all the parts that are available. If you are interested in all of it $20.00 plus shipping or if you just want this retainer for $10.00 plus shipping. I would need a zip code to figure shipping but I thing everything but the top cover and shift forks will fit in a flat rate box for $11.35 or the bearing retainer by itself will be less. Thanks

Re: WTB Front Bearing retianer sm420
 

Guys, Todd's trans is a New Process 435 according to the casting number on the case.
The casting number on the front bearing retainer is for GM w/tapered bearing, 1967 according to my books. Sorry Todd, not trying to derail your sale, but if odog is positive
he has a SM420 then your cover will not work. The bearing retainer for the SM420 should have a
casting number of 3761932.

Re: WTB Front Bearing retianer sm420
 

No problem on my end. Like I said before, I do not know what the transmission is and I do not want to sell the wrong part to some one so I am thankful for any and all help. I still have the entire transmission so I can check anything or get pictures, just let me know. Thanks

Re: WTB Front Bearing retianer sm420
 

Stovebolt, can you de-code the bearing retainer I have in the 4th post to this thread? I haven't been able to find anything on it. GM 12 cast into the housing, 5 1/8" in diameter and has " 3920748" stamped into it. Would be good to know for future reference. Thanks for any help.

Re: WTB Front Bearing retianer sm420
 

Can't find any info on that number. Do you have the whole transmission? If so I can probably ID it by the casting number off the main case.

Re: WTB Front Bearing retianer sm420
 

Now I don't feel so bad as I couldn't find anything at all on it, LOL :lol: Don't have the tranny it came from, had it for years and don't remember how it showed up. ?? Oh well. Thanks for the try.

Re: WTB Front Bearing retianer sm420
 

todd stovebolt is right that wont work. it looks good except 4 the tapered bearing. Thanks for looking 4 me sorry we couldnt make a deal. Stovebolt thanks for catching that I appreciate it. Ironhorse that may be off a sm465 rans. those measured 5 1\8 I believe.

I just got off the phone with the guys at Novak and ordered 1 from them. didnt want to go that route very badly but kinda need to get this going. Thank you guys for looking for me.

No problem.

Re: WTB Front Bearing retianer sm420
 

Sorry I could not help. I am glad that we did not make a deal on the wrong part. That does not work for either of us.
