Volvo RWD 140-160 Forum

One of my manuals (can't find the other) shows a nice ear cast onto the bellhousing for the clutch cable but mine, of course, does not have any such thing. Anyone care to post some pictures of their clutch cable bracket to ease the fabrication process?

Otherwise, tomorrow is looking like d-day for the manual transmission swap into the car.

I helped take one of these out of a 164 today and in the first picture you can see the "ear". It is in the upper right corner, has the little notch out of it. The cable goes through that and then attaches the clutch arm. what year and make are you putting this in?

Here are some pictures of the lever style bellhousing

I have already measured and it appears to be the right bellhousing - it is also threaded because my transmission is not (apparently they came both ways). I looked it over pretty carefully and it looks like the cable ear was removed because there are grinding marks on the edge near the starter. I was staring at all the parts today wondering what I was missing and all i could come up with was a bracket for the clutch cable and a pilot bearing (this is waiting for me at the parts counter). I went in a checked my manual and assumed that all bellhousings did not have the ear and was just going to fab a bracket that mounted onto the bellhousing bolts. I am still pretty sure that is all I'm going to do tomorrow unless I fall into another bellhousing - I will make some calls.

You've never said what car or what engine you are putting this tranny in.
If it is a 164, B30 engine, I have a bellhousing that is complete (except for clutch shaft and fork).
If you need it e-mail me offline.

I think you best stop working on this project... now.

Until you get sorted what you have and what you need... if the bell housing is threaded, as opposed to the transmission, you don't have an M410.. you have an M41. And if you have no ear on the bell housing for the clutch cable, you have no way to install the clutch cable, and its difficult to shift without a clutch cable.

Sounds to me like you may have an M41 transmission with a 122 or 1800 bell housing set up for a hydraulic clutch.

Yes.. pictures would be nice. And all is not lost.. parts are available. Folk here just need to know what you have and what you need.

Well, despite all the alarm bells, I will be putting the tranny in.

Fine, so it is an M41. I will make a bracket for the clutch cable; it's an arcane art form known as fabricating. Yes, I have already measured the bellhousing - it fits the tranny and it measures the same as the BW35 bolt pattern on the block. I measure before I buy. Incidentally, I didn't know the crank pulley bolt trick Rhys dropped on here so I bought both a six bolt and an eight bolt flywheel.

Last but not least flywheel bolts - are the flex plate bolts long enough? The flywheel looks pretty thick. Because the car originally had a 4spd there is probably an even chance that they re-used the flywheel bolts for the flex plate anyway but I would rather spen a couple of bucks on extra bolts before rather than hooking a ride on the bus for them later.

Hello,

Unlike a 4 cylinder M410, the correct M40/M41 bellhousing for a clutch cable is very easy to locate.

You can reuse the flexplate bolts to hold the flywheel if you want.

I believe 8 bolt crankshafts use metric bolts so if you buy new, get hardened bolts.

I agree.. I would not try to fabricate a clutch cable bracket when the right part is so readily available... a bell housing with teh correct cable attachment is easy... any 140 bellhousing from a stick shift car will have the right one. I'm sure I've got a couple, but I bet you'd be able to find one more locally..

There is a lot of force on that bracket, and changing a bellhousing later is a pretty big job.

Sounds like your on the right track in other regards though..

You guys are killing me. Parts are not available here and I have already paid good money for the parts I have - they were not local. There is one yard on the island that has Volvos and it is attached to a dealer. When I was looking at carbs, they really tried to push a set of ZSs on me not rebuilt or anything for more than Rhys would charge - they are the same about other parts and they like to talk about the demand they have to ship parts around the world. I bet I have paid more than double what you are willing to pay for the parts I have needed and then doubled it again for shipping.

If there is another 140 rolling around Victoria, I haven't seen it and it likely only comes out on weekends or something. I have seen one 130 and one 160 - neither of which were daily drivers. Other than the body, mine was in very bad shape - I don't think they have survived here.

On the subject of fabricating well ... i used to run a custom metalwork shop in East Vancouver. Stock in trade was stainless handrails. Still did a lot of brass but there is stiff competition from off the shelf foreign suppliers and people like the low maintenance of brushed stainless. I stuck a Cleveland in a 67 Econoline, had a Suburban on 48" military tires with a diesel and a 5 ton transmission, a Mazda B2000 on 37s - all of which was custom fabrication. I think the clutch cable bracket will be fine and will not need replacing unless I get very drunk before I weld it up - even then it will likely be serviceable but just have ugly beads ;)

Well... if you must fabricate, that's your call.. but it's not just that ear for the cable.. unless it broke off or something.

My assumption is that you have a bell housing from an early 1800 or 122 with the hydraulic clutch... If that's the case, the throw out arm that's in there pivots between the actuation rod and the throwout bearing... such that you push on it (via hydraulics) to disengage the clutch, whereas, a 140 with cable clutch, that pivot is opposite the throwout bearing, such that the arm gets pulled on by the cable when the pedal is pushed.

A bell housing with throw out arm from me would be sent for the cost of shipping only... assuming I've got one. Seriously.. I don't mean to dissuade you... I just hate the idea of all that fabrication work to end up with a result that might not work as well, and might be more prone to breaking...

Thanks for the offer Matt, but the bellhousing has obvious grinder marks on it and came with a stamped metal arm that fits the cable I bought. It will be fine.

Good to know the flex plate bolts will be long enough for the flywheel. I do have a six bolt crank. Unfortunately for the volvo, I spent seven and a half hours on the beach today instead of changing the transmission ;). The only thing I can see as an impediment to making the swap is that it looks like whoever did the auto swap broke (or maybe just chiseled) off all four bolts for the crossmember. I will have to remove those before I bolt up the transmission.

Thanks again!

At the risk of completely screwing things up for you, have you measured the bellhousing to make
sure it is the right size for your engine?
If your bellhousing is set up for a slave cylinder rather than a cable, it may not fit your engine, either.
Measure and make sure before you tear a bunch stuff down!
I can provide measurements for both b18/B20 bellhousings and also B30.
They are about an inch different.

Hello,

Can you supply some pictures of your bellhousing?

I have a bad picture of mine... It's a B20 M410 bellhousing, and I know it works because it's in the car and been runnin' fine for the last few weeks.
