Next remove all the large needle rollers from inside the input shaft and put in tray. Both M20's and M21's with as much ease. Positrack diff on the Vette and I can burn rubber on both back wheels at almost any speed if I let my foot get heavy. Well there is reason why your killing them, the cheap parts or how you drive. I will have a much more thorough look at everything and probably post some more pics.
It is more correct to call it an M20 but that isn't exactly right either although it's pretty close to correct. You can locate cars available on social media sites, in your newspaper, as well as specifically at your neighborhood car dealerships. I went with a Muncie because one popped up for the right price and I don't regret it at all. End of submission by Ben Simpson. Are you aiming to deliver a huge group in vogue? However I am not sure if this is the orginal box and therefore I would like to know the differance in input shaft length bewteen a 6 and 8 without stripping the box. Pretty sure you can't buy them by themselves. You'd only want the Muncie for big torque applications like a 377ci-400ci small block or big blocks.
Boy I'm going to be in the crap when I start pulling it apart. I realize everything has to be pretty damn squeaky clean in gearboxes and im fretting about it! The cluster gear has a lot of washers, a spacer and needle rollers. All Speco Centreshifts are complete with shift rods, selector plates and rubber boot kit where applicable and all hardware needed for simple installation. Interesting read on the various opinions on the various boxes. Note the one to the front of the gearbox can go eitherway around however the back one has a section removed and must go towards the center. And this is the only car I have ever had a major mechanical failure in. I'm in the middle of rebuilding my aussie 4 speed and have a couple questions.
Gearbox is a 4 speed M? When building your box I use Mobil Waxrex basically industrial vacaline to help hold the needle rollers inplace in the cluster. Yel327 has a lot more experience than me when it comes to these boxes. I forget what its called, sits on the input shaft between the shaft and clutch. But the down side of straight cut gears are the noise that they create reverse is straight cut. A V8 M21 is no stronger than a 6-cylinder M20. Ok you should have done your cluster and input shaft. Correct M20, 21, 22 are just option codes.
I don't know how that happens, I have had them out in the open air maybe a day or so, can rust form on them that quick? Havent got a 6 Cyl 4 speed out of a car here to measure the Shaft lengths but It's sure going to be very close! From memory the M22 has same gearset 2,3,4 not first obviously as teh M20, thus you end up with a big gap between 1st and 2nd and gap between 2nd and 3rd. Its quite funny to put a standard 5 speed knob on a holden with a M20 or M21, and park it on the kerb so they have to go forward, but then again, they will hit 4th thinkin its reverse and stall the motor, just like they will hit reverse thinkin its 1st and go flying backwards!! Spray a degreaser into the cluster to try to wash out as much waxrex as you can. The M2x boxes were good boxes and are reasonably strong as long as you dont start abusing them then they generally wont last. Doesn't make it an M21. Its funny I was talking to are local trans guy today about it and his response was who told you that crap.
You must check all internal bearing surfacse where bearings run, with you brass rings, they must be checked on the gears they came off. But in the defence of the all aussies, Most of the blow ups have been caused by driver abuse. The bearing in it is pretty stuffed and needs to be replaced, how do i go about that? Either Dr Terry or Yel327 I think? Most had blown input shafts and clusters. Thanks mate Snype Get Stoned - Drink Cement An M20 will hold out exactly the same as an M21 in equal condition behind a V8. Could it be a later M21 or M20 from a Commodore? This was fitted to 253's in 1 tonners for towing, and also in a few other cars. The car is fitted with an 8.
The clusters are as listed above. It will melt with heat approx 30deg+ but may affect cold gear changes. They are likely to be worn and wobbly by now too. But I have been told to use 3. I have had a box last twenty mins and another last for years. If you have a digital camera it will help you to take some pics. It is not like an M20 is a 6 cylinder box.
Next lay down the mainshaft with the small end pointing towards you with a pair of circlip plyers remove the circlip and put in tray, then you will notice a hub with a slot a brass ring and a gear, on the back side of the gear gently with a scewdriver, lever up the gear. Pre-check gear lever position prior to fitting where a bench seat is used in its most forward adjustable position. Good for thing like A9X's. Numerous car dealerships make use of the newspaper to list specials as well as sales on cars that they're trying to move rapidly, as well as this can enable you to conserve a lot of money on a high quality vehicle. Whether you wish to locate one online or in your neighborhood newspaper, you can locate the ideal vehicle for your spending plan as well as personal demands. I assume we are talking about a V8 box. The next common cause is the 2nd gear circlip, it breaks and mashes in with the gears or welds itself to the main shaft, you only find this when you go to change a gear off the main shaft.
I have lots of fun in my Black 71. So you can juggle bits to get the right clearances right. Totally different box but same design with reverse in the extension housing unlike a Saginaw. But very unlikely if you didn't clean the gears thoroughly with prepsol etc to remove all of the oil. But, each to their own I reckon. I don't know what the actual differences between a Celica and a Supra box are. Aussie 4 Speed selector shafts.
