I can't find my last thread on this . Do all these take the same clutch and throw out bearing ? all cars ion working on are 70-75 slant six cars darts & dusters . Trying to order stuff and things are not as clear as id like. seem no sense in dropping trans and not replacing both. two of the cars are looking to do swaps and 2 cars are squealing bad when clutch is pushed in and several people told me it was throw out bearing. If they are no the same can I get links or part numbers to them ? I love brewers but man I can afford. I'm looking at eBay and Napa. Napa only lists A230 and A833 . nothing for a903 or a833od .
 
As far as I'm aware, they all use the same disc spline (1x23) and throwout bearing, as long as you exclude the Hemi A833, anything 4WD truck, and 2WD truck with a top-mounted shifter or granny low.

In most auto parts systems, passenger-car 3-speeds are all lumped together when it comes to clutch stuff. Sometimes they're even tossed in with the 4-speed stuff.
 
Yes those all **should** take the Same part for the TOB.
All Are the same Snout Diameter except for the Hemi 18 Spline input Shaft which has a Different TOB.
May I recommend the Hays 70-110 TOB. for this install. Why do this job again due to questionable parts quality?

The parts store parts and rockauto may have vague quality or have Plastic Sleeves or parts on them.

Alternatively, you can reuse your existing sleeve and just buy the Bearing separately and have it pressed on.

I dont have any clutch Kits part #'s handy for a slant 6 on hand. If it's a stock motor than any quality Clutch and PP set should do.

You can always have your parts rebuilt by falcon clutch or kentucky clutch too.


Cheers!

I just don't want to buy stuff that won't work lol . money is tight and lift time is limited once I put put on a. friends lift we have sat and Sunday only to get cars off it. So it so important to have correct stuff on hand the first time. I do lot of stuff at home but I can't do engine or trans swaps in the driveway ( not comfortable with it ) so I take to a mech friends shop and I assist with this type stuff but deal is it must be gone by Sunday night.
 
I hear you on TOB , what about the clutches ? all these cars are pretty sad slants , my car is a 198 pushing maybe 85hp now lol but I want a good tough clutches so they dont need changing again ever lol.
 
Not sure.

I have not put a parts store kit clutch behind any of my slants in the last 20 years.

Part of Chrysler Corporation's "Extra Care in Engineering" motto was not having 4 different parts for an equal number of applications. Hell, 2002 B-vans still had '60s A/B armrest bases in 'em. How long did the new-for-'72 side-marker lights last in production? Some '80s FWD cars came with them.

Get the flywheel diameter right and you'll have no problems.

On the throwout bearing, Timken #610436 is what Chrysler put in 'em.
 
'72 Side markers were Still available on the '93 D150

I dont know what flywheel wheel is or could be unless on a lift and drop trans right ?
 
wouldn't all slant A body cars 1970 -75 be the same ? I dont know lol . I have 3 of these cars needing love asap and my car I want to go to 833od in my duster. it dead in the water right now.
 
If it's a Slant, it should be a so-called 9.5" flywheel, so called because that's what clutch it takes. It's got 122 teeth on the starter ring gear. I'll be putting an A833OD in place of the factory 3-speed in my '68 Valiant. That requires a different bellhousing, but the flywheel/clutch/pressure plate/throwout bearing/pilot bearing (bushing) are the same parts.

The A833OD uses a specific bellhousing with a 5.125" pilot opening. The first year for that bell is 1975 and it's overdrive-specific. '75-'76 A-bodies used it, as did '76-'80 F-bodies & pickup trucks. The '81-up truck bell can also be used but it requires a similar-year clutch fork. The throwout bearing still didn't change, though.

If you look up the clutch for the car, unless some serious shenanigans have happened--which would be obvious--you'll get the right parts. Don't over-think this.
 
all clutches listed say 10 1/2 for 4 speeds . but not clear answer if are same for slants . seems strange . thanks for the 75/76 note . I knew they came out later but thought it was 73 ish
 
Stop concerning yourself with the transmission. You're not buying a transmission.

Are you trying to do this on NAPA's website? I tried; it's dreadful. Still, if you go to the top of the page and enter the vehicle and engine, then search "clutch" it's going to give a bunch of automatic garbage. Among them you'll find two manual options: 9.25" and 10.0". 9.25" is the stock replacement; the 10" is a size upgrade (trucks used a 10" disc on a 122-tooth flywheel).

It doesn't show any manual transmission options for lookup that I could find. No 10.5" option is shown because that size will not physically fit on the flywheel.

If you need a clutch for a '72 Duster with a 198, look it up for that. Stop trying to force the issue of what transmission it fits; as I said above they all use the same clutch and its attendant parts.
 
10 1/2" Clutch and PP is for the 143 tooth Flywheel in V8 land.
If you get that one you will be returning to the parts store.

Most V8s are 130-tooth flywheels. The 143-tooth is pre-1970 HP big-block only, excluding the Hemi (172 teeth from 1966-'69). 143-tooth flywheels take an 11" clutch, which was never available with a small block. Everything V8 1970 & up uses the 130-tooth 'wheel.

The above only applies to cars. Trucks and vans? That way be dragons. I don't go there. :D

Thanks for the correction. I meant the 130 tooth!
 
The advantage to the 10" disc is more swept friction area. Better grip, and probable longer life.

Disadvantage, and this is relatively minor, is that it has a greater flywheel effect on the input shaft of the transmission. Shifting requires a bit more effort, but again, it's not a huge deal and it's still easier to shift than any 10.5" clutch. If your synchronizer rings are worn it will be more noticeable, though.

well we not talking about v8s at all and that's the confusion for me and part places . slants and what TOB and clutches for a 3 speeds and or 4 speeds and having nothing listed. you say they are the same ill go with it
 
If you're asking a human being for a clutch, tell them "I have a '71 Duster with a 198 six-cylinder and I need a clutch." (or whatever car/engine you have). If they don't ask you which transmission it has, don't confuse them with information they don't need. If they do ask, no matter what answer you give them, you're going to get the same clutch because only one clutch fits the Slant Six, with the exception of the 10" upgrade (the only difference is the disc, by the way). If they ask what size clutch, and you want the larger one, tell them the 10". If their system delivers a 10.5" clutch which won't fit your flywheel, find a better parts store.

I've been in parts, both dealer and aftermarket, for almost 36 years. You're making this entirely too hard, believe me.

Also, since I don't recall seeing it mentioned, you need to have your flywheel properly resurfaced when installing a new clutch. It will dramatically increase the life of the disc, as well as removing all or most of the heat fractures you will find on the flywheel surface. Don't worry about 'em, don't post on the forums about 'em. They're normal, and if some remain after resurfacing that's normal too. You have a Slant Six, not a nitrous-fed W2 340. Resurface the flywheel and you're good to go.
 
I have a 833od out of a truck complete. It still has the clutch, flywheel TOB, fork, and bell housing and even the truck shifter.
I can look at or send pics tomorrow if that helps.
It is all on the floor of my shop.
