611 Posted July 5, 2022 Share Posted July 5, 2022 Hi I had someone with an A series contact me through my Opel blog asking if i knew what the issues was he was having when fitting the 5 speed to the A. If anyone has any thoughts here is an over view. He had a red top (or similar) fitted that ran like a bag of crap, so he got a 2.0L CIH engine, a 5speed box and fitted these in place of the other engine and box. When he first started it up it was squeaking, so he did some reading and decided it was the needle bearing in the end of the crank as he had not changed that before fitting the engine, so pulled the box, fitted the new bearing popped the box back in and started her up, problem solved. Until he went for a drive and after 1/4 mile it started to squeak again. (i have attached a video he sent of him turning it over so you can hear the noise) it now squeaks all the time? He is now convinced that the shaft from the box is too long and touching the inside face of the crank, getting it hot and the grease is melting and knackering that new bearing?? not head that before but thoughts? He also say that first and reverse wont engage when its running with the clutch down and that if its running and he has it in gear with the clutch down the car creeps like its slightly engaged? and recons it the issue with the shaft being turned by the crank where its touching. He has auto box oil in it and not the proper stuff and he said it has a new clutch and release bearing Any thoughts?? Does he have more than one issue??

Jessopia74 Posted July 5, 2022 Share Posted July 5, 2022 Has he tried to use the clutch plate from the redtop with the 2.0 I wonder. Sounds like the big boss on the clutch plate it touching flywheel to me. Quote Link to comment Share on other sites More sharing options...

Sounds like the big boss on the clutch plate it touching flywheel to me. Not sure. He is trying to see if he can solve it without taking the box out again as its a bugger to get in and out on the A. He said if he un bolts it and moves the box out a couple of mm it stops it? so its got to be something touching when its bolted up. I will pass on your thoughts. Thanks for the help Andy Quote Link to comment Share on other sites More sharing options...
®evo03 Posted July 6, 2022 Share Posted July 6, 2022 Would it be the shaft or clutch? Or the spigot bearing? Shame, as a few mm spacing cures it. Think the box is gonna come out. Is it easier to drop front subframe with engine and box in place? Possibly run it. Quote Link to comment Share on other sites More sharing options...

H-400 Posted July 6, 2022 Share Posted July 6, 2022 35 years ago I changed a 4-speed to a 5-speed without changing my clutch/needle bearing. So it would wonder me if the nose of the shaft is too long. Quote Link to comment Share on other sites More sharing options...

So it would wonder me if the nose of the shaft is too long. I suppose he needs to space the box out evenly all round to see if it cures the issue, then hope it is the shaft that is too long and not something else as otherwise it will be box out, shorten the shaft, box is, noise still there, back to square 1! I have never heard of anyone have that issue, but with an Opel there is always a first time for everything! Quote Link to comment Share on other sites More sharing options...
611 Posted July 8, 2022 Author Share Posted July 8, 2022 Ok, a bit of an update. 2mm washers added to space the box out have stopped the noise, but he has said he is using the clutch friction plate from a 1.8 manta B 246mm one. Any thoughts if this could cause any issue? Thanks Andy 2 Quote Link to comment Share on other sites More sharing options...

Any thoughts if this could cause any issue? Thanks Andy Yes, the clutch driven plate is wrong, I thought perhaps it’s the case. He needs to swap it to correct plate as there is a difference in the boss length of the clutch. It’s bottoming out. IIRC you can flip them (run backwards effectively) without much issue, but then the travel will end before plate is fullyworn. Recommend he speak to CG motorsport in Leeds https://clutch-specialists.co.uk Edited July 9, 2022 by Jessopia74 Quote Link to comment Share on other sites More sharing options...

Looked on auto doc at 1.8s friction plate and 2.0 Cih plate the centre boss is the same size and only difference is 1.8s is 3mm smaller on surface area 1.8s clutch plate is also half the price Quote Link to comment Share on other sites More sharing options...

Reason I say is that there is difference between manufacturers. Quote Link to comment Share on other sites More sharing options...

Not sure mate. He has some weird reasoning for why things are right as he sees them. Im going to leave it up to him to work it out from now on as he still seems to thing the clutch is alright and its the box shaft that is the issue. He may well be right!!

cam.in.head Posted July 11, 2022 Share Posted July 11, 2022 if its the box actual input shaft why would it be different .surely the engines use the same crank be it 4 or 5 speed or auto and the same spigot bearing .if you changed a box you wouldnt have to fit it to a different engine or change major bits .thats assuming that it is a manta box ? does sound more likely an issue with the plate (or clutch related) is the release fork correctly adjusted ?is the fork actually in the bearing slot ( cant see that you would actually get it in or enough afjustmentif not but who knows.

He said its a getrag 240 box but i have not seen any pics of it. i did ask if he had the clutch adjusted properly, but now he says he is running the 1.8 clutch plate i wonder if the adjustment being right for a 2.0 is different for the 1.8 and causing the issues. To be honest, if i was him i would make sure the clutch was the right one for the 1.9 CIH and then go from there. He said he couldn't get 1st and reverse when it was running and i check which oil and he said he was using auto oil which was correct for that box and that would not be the issue, i gave him the correct part number for the oil and he reluctantly bought it and change the oil and guess what!! no issues with the gears now 🙂 Im going to leave him to it now as he is one of those people that ask you for advise and then says what he is doing is correct, which it seems it isn't always 🙂 Andy 1 Quote Link to comment Share on other sites More sharing options...

Ok step away 😂 You know it will be one of the issues already mentioned, but arrogance can get away of the obvious to some 🤦♂️ 1 Quote Link to comment Share on other sites More sharing options...
