Popular Post cruiseliner64 Posted August 17 Popular Post Share Posted August 17 Hi all,well we took our Cruiseliner out for a drive today after getting insurance organised.it was really enjoyable to be out and about in it at last.the drive did show up a few niggles though.the gear change is really poor,its like stirring a bucket of bolts with a straw.me thinks the famous shift tower needs a rebuild but there is loads of power in the old girl and shes fairly comfortable.steering was good and the brakes were very good too.all in all we are really happy with it.anybody know if the parts are availible to sort out the shift tower or is it mend and make do with what we have.any ideas would be great.thanks Paul 8 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/ Share on other sites More sharing options...
mrsmackpaul Posted August 17 Share Posted August 17 I would think the shift tower should be pretty standard parts that can be replaced pretty easily Saying that I have never worked on one But Im guessing holes need rebushing and rod ends need replacing Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557171 Share on other sites More sharing options...
BOBWhite Posted August 17 Share Posted August 17 A guy on here rebuilt the shift tower on an Mh awhile back, not sure if there would be any similarities. Do Cruiseliners have a shift tower like an Mh or do they have the older style that goes in between the seat to the floor? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557182 Share on other sites More sharing options...
cruiseliner64 Posted August 17 Author Share Posted August 17 Yeah the gear lever goes through the floor between the seat and doghouse.i know maxitoqure gearbox takes a bit of getting used to but this shifter is very sloppy.it was the only thing that kinda spoiled the drive a little otherwise it was fantastic to be driving a cruiseliner at last Paul Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557186 Share on other sites More sharing options...
mowerman Posted August 18 Share Posted August 18 For what I remember shift like a dream very easy to move very tight, but It was only a couple of years old when I had it… good luck I was going to say just good lubrication with all the moving parts but if it’s sloppy, you definitely need something else… bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557251 Share on other sites More sharing options...
Popular Post mrsmackpaul Posted August 18 Popular Post Share Posted August 18 Once you get the sloppiness sorted Take your time shifting, no clutch pedal all the way to the floor like a European truck as this put the ckutch brake (if it still has it fitted) on and make things harder And take your time, there's a lot more spinning around in a Maxitorque than a RoadRanger or ZF box They are pretty box I find they can't be rushed at all On a 10 or 12 speed, about 400 revs between changes On 5 or 6 speed about 800 revs They do take a bit of getting used to if you have never driven one, just take your time For the rest of you lot from Yanky land and there abouts In Australia European and Japanese trucks generally don't have a clutch brake at all, only American based trucks Most truck drivers in Australia even use the clutch brake as most are used to driving with out one Even European trucks with RoadRanger boxes don't have a clutch brake fitted Paul 5 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557255 Share on other sites More sharing options...
Popular Post Joey Mack Posted August 18 Popular Post Share Posted August 18 the clutch brake is only used when stopped and you select the next ger to go,, forward or backwards.. Paul is so smart.. but who am I to judge,, I look up to Paul.. Mack transmissions shift slower than Eatonas Paul said,, I do a count in my head with the Mack trans,...

cruiseliner64 Posted August 20 Author Share Posted August 20 Thanks for the tips lads.the shift on our Cruiseliner is sloppy as in i cant get 1st gear at all 2nd can only be got when stopped 3rd and 4th are no problem and 5th can be got sometimes.the range changer goes smooth enough..filled shift tower with oil but it ran out passed the rods pretty quick.think i need to rebuild it....

Joey Mack Posted August 20 Share Posted August 20 as far as oiling the shift tower,,,, It is splash lubed by the spinning gear sets.. are the ujoints in the shifter shaft sloppy? a little slop goes a long way.. my guess is there is 2 close to the tower on the tranny? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557336 Share on other sites More sharing options...
mechohaulic Posted August 20 Share Posted August 20 my bet is on worn shirt linkage u-joints as above mentioned. 1 &2 are over towards seat ; worn u-joints would have the lever hitting seat preventing shift fork from proper alignment in transmission tower. 3 & 4 are easier since shift lever is in middle . cab up AND SECURED hold shift linkage going to transmission while moving shift lever. should be able to check for worn u-joints /bushings.. check shift lever side ways movement with cab down then do same check with cab up . wager side movement up cab is greater . 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557337 Share on other sites More sharing options...
Joey Mack Posted August 20 Share Posted August 20 Mech? is it the same as an MH? I remember doing shift tower bushing replacements and u-joints.. I think I still know how to do it today.. been a while.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557338 Share on other sites More sharing options...

mechohaulic Posted August 20 Share Posted August 20 have seen some with so much slop in linkage ; after centering the lever going to flip hyd down lever, shift lever moved and away goes the range selector button on the shift knob. oooops 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557341 Share on other sites More sharing options...
cruiseliner64 Posted August 20 Author Share Posted August 20 Hi all,the shift tower that is leaking oil is under the cab floor.see picture.inside it the two rods have gears which move with the shift lever.the oil is leaking from the ends of the rods.i filled it with gear oil but it was empty in a few days.i wonder if the gears in it are worn but dont know what the amount of play should be.the link from it to the tranny has only 1 UJ which doesnt seem to have any play in it.many thanks for your help lads this is a great site.

cruiseliner64 Posted August 20 Author Share Posted August 20 Sorry i meant to say the link from the tower has 1 UJ at each end.1 at the tower and 1 at the tranny.

Paul The shift towers has to be rebuilt ever 2 years or so. It was a very poor design. I can't remember all the part numbers but typically you replace the outer boots, bushings (80AX747?), seals (88AX349P3?), shafts and gears (because the teeth wear down). These was a Mack service bulletin on the rebuilding procedure stemming from customer complaints about a sloppy shifter and oil leakage. The side cover is reinstalled using silicone sealant. 5 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557355 Share on other sites More sharing options...

BOBWhite Posted August 20 Share Posted August 20 The guy that rebuilt his Mh's shifter had to cross reference a lot of the parts, specifically the U-joints. "The U joint on the shift linkage is a Rockwell L6N or MOOG 861 if anyone ever need to look" Probably a different setup on a cruiseliner but it could be the same U-Joint. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74475-first-drive-in-the-cruiseliner/#findComment-557363 Share on other sites More sharing options...
