cpgeneration Posted June 19, 2021 Share Posted June 19, 2021 Does anyone know the secret to installing a Haldex swing style clutch brake with the crazy upside down Mack fork in the way ?? Bell housing hole needs a rework with a sawzall...!!!😵 after 2 hours i fell asleep under there and never did get it in. Thank You.

Onyx610 Posted June 20, 2021 Share Posted June 20, 2021 (edited) What seems to be the issue with getting it in? Hardest part is getting old one out.

mrsmackpaul Posted June 20, 2021 Share Posted June 20, 2021 Sorry Im of no help, I rarely use the clutch brake, it is out of adjustment Can understand it's gunna be a challenge working thru that little hole I'll follow along to see what I can learn Paul Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475529 Share on other sites More sharing options...
mrgumby Posted June 20, 2021 Share Posted June 20, 2021 I have big fat hands and fingers I’ve had to pull the clutch fork and shafts out of the housing for extra space most the new ones you just loop over the top of the shaft or where ever the ears line up and pop the button in to locks it Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475531 Share on other sites More sharing options...
Joey Mack Posted June 20, 2021 Share Posted June 20, 2021 I have had a helper to press the clutch fast and hard for me, while I had a piece of flat stock, or a large screwdriver put in place opposite the button, so that the throwout bearing doesnt just move at an angle relieving the pressure to push the button in..... I still dont like these clutch brakes. I prefer the 2 piece aluminum type with the 2 skinny allen headed screws. and the hole is way to small, as you say... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475532 Share on other sites More sharing options...
MACKS Posted June 20, 2021 Share Posted June 20, 2021 Should tell u on the brake what tang goes in the slot first,it’s a pain but not that hard at all..

mrsmackpaul Posted June 20, 2021 Share Posted June 20, 2021 Just wait a moment, European trucks as well as Japanese trucks dont as a rule have a clutch brake fitted Just push the clutch in and wait a moment, then slowly shift the stick into gear, you can feel the gear engaging, not grinding but actually engaging Maybe wait 5 seconds at the most before sticking it into gear Also I hardly ever do city stop start driving so I might have a different opinion if I did, I have driven thru plenty of big cities in Australia in peak hour I just mainly drive in rural Australia Paul Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475538 Share on other sites More sharing options...

Those allow you to force the lever slowly and after waiting for a bit of time the traction eliminates the speed difference between the engaging splines. Theory tells this style of the shifting mechanics is less reliable since the weakest point in the tranny is synchronizers. In practic it looks to me like good quality units work about forever.

mrsmackpaul Posted June 20, 2021 Share Posted June 20, 2021 Some do, not all A lot of European trucks have a Roadranger in Australia as do the bigger Isuzu's and still have no clutch brake, you just need to get used to driving them Paul Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475551 Share on other sites More sharing options...
Mark T Posted June 21, 2021 Share Posted June 21, 2021 If there's no clutch brake on a Roadranger , doesn't that make it difficult to adjust the clutch or give it way too much travel even if the bearing is close to where it should be ? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67065-what-is-the-secret/#findComment-475556 Share on other sites More sharing options...

The old one removed itself and was off and floating around, i will ask the driver how he managed to make it come out... but i already know, big dent in the floor board where the pedal stopped.. makes it even worse that it is a quad box the hole is the size of a postage stamp..
