A few steps further down the track, engine off the front suspension, M41 box ready for a sympathetic refresh of seals and oil but not much more as it was working perfectly when I last drove Harry, will get a new clutch, machine the flywheel, etc, the engine will be looked at to see if there is any major wear or disintegration of things while he was laid up but most of that was done when I changed the cam to a Waggott D grind a few years back, new steel timing gears, and new front and back crankshaft seals, I did change the brakes to a set of 71 164 ATE 4 spot calipers and replaced the bushes and ball joints but will take it all apart and make sure things are all ok, roll on Christmas!

Good to see Mark, are you going to do the Mercedes oil cooler mod.

Been gathering some more stuff, new steel and alloy timing gears, new crank hub, new timing cover and upgraded seals, rest is in refurbishment and or paint mode, a Check of wear in the bores,crank and cam thrust play all almost zero wear, seems it will be a clean down and reassemble. Yes,will do the oil cooler mod, seems silly not to. Same almost zero wear is in all parts of the M41, so new seals a few bearings and bolt it together with a new clutch and pressure plate. The front suspension will get taken apart over the next few weeks, new ball joints, new bushes, took the ATE calipers apart, again zero wear so new seals, a paint and ready to be put back on. Will get the head back next Friday, all new injectors, sensors and switches a Bosch-new MAP sensor and new ECU forward wiring loom, thinking I should have a working DJet B20E ??? fingers crossed! Waiting for the rest of the body panels, doors, nose piece and bonnet, and can start putting the actual car back together!

Hi there 144 B20 brains trust ? am I over thinking this, hmmm, double groove crank pulley (from a AC fitted 74 144 with a B20) V current single pulley, the single pulley has a steel collar that the single groove pulley fits onto, is it as simple as that the twin groove has that collar built in to the casting, it all seems to be right dimensions wise, am I missing something? Oh, yes I know, Ihave not fitted the timing cover ???

If this works, Harry, my 1973 144 GL will have air!

Massive thank you to my Nephew Eric, who works at Northern Road Wreckers, read some of the posts regarding lower control arms, dug around way down the back and there she was, , going out with him over the weekend to see what other bits and pieces may be worth saving, it’s being crushed next week.

Hope you are all well out there in Ovlov land ???

If you are planning on long periods of high revs and less rotating mass then single pulley. The doubles are very thin in the keyway. A 164 cover and double pulley is a slightly bigger diameter at the pulley shank and therefore slightly stronger.

Are B20 and B30 timing gear covers the same shape? AFAIK, they're not interchangeable, but I may be wrong.

    Yes you are correct, the collar is in the casting for the twin groove. Almost every one I have seen has a fine hairline crack at the keyway thin wall section. If yours doesn't, then take care with install that the key is sized to the groove before installing. They also appear to wear a bit easier at the seal face, causing a groove. I was going to try fitting an engineering speedie sleve or similar to solve the problem, they are very thin and though polished metal.

    I love the shape of the 73 cars, and long live Djet

    I've had no problem. You do have to fill one or two holes used for location dowels on the B30, otherwise it will leak oil. The late B30 already has a lip seal too.

    Hi there the Volvo brains trust!

    query on my 1973 144 ATE brake proportioning valves, these are definitely the original ones, just took them out of the car and gave them a bit of a clean up while the car is up on the hoist and diff about to come out.

    Firstly it looks like there is no maintenance able to be done short of uncrimping the covers and see what is underneath, secondly before I do that is there any form of test to make sure they are doing what the Swedish gods designed them to do? I have never had a brake problem but while I can get to the underside and get to them I thought Id just make sure they are fine.

    All the rest of the braking system will be new or refurbished

    Thanks in advance ??

    Be safe out there!

      Assuming they’re not blocked (ie when you bleed the brakes you get good flow to the rear brake bleeders) then they should be fine. I don’t think you can do anything to them. They are a sort of proportioning valve that prevents the rear brakes locking up prematurely.

      Hi Greg, thank you, kinda thought that, and yep never had a brake problem and they tested up ok, will dust them up with some paint and put them back, one thing less to worry about, Mark

      Harry's looking good Mark. As is Katie and AJ. I'm thinking though that your collection is not complete. You also need a notchback VW with fat wheels and a Datsun 1600 with Turbo and oil cooler stuck through the bonnet. Perhaps throw in a Mainline ute as well? Seriously though, Harry will be worth the wait.

      Hi there the Volvo brain trust ? always wondered why it was only old blokes had wicked cars then realised the only time you have to do stuff is when you are heading towards or already retired, in my case I just joined those long haired, mung bean eating, dope smoking Blue Mountains types as a ‘professional’ retiree, and NOW can put a bit of time into getting Harry back on the road…..getting a pair of mints Cibie Oscars to make it a 4 Cibie (2 Super Oscar and 2 Oscar) rally look certainly has assisted motivation. Retired yesterday ?

      Enjoy my friend, Im looking into it to, Im over these 5am winter starts

      Congrats on retirement. I took an “early” buy-out from Holden at the age of 48 and haven’t looked back since. Having said that, I don’t find much time to work on MY projects! LOL!

      You can't get Harry on the road before Vivian Mark! I'll have to get really motivated now. Should we set a goal to go to the 2022 OzVolvo Nationals maybe? Congratulations on finally taking the leap. ?
