5sp conversion

[Ruffy]

short of spending another 5 hours searching i figure it will be easier just to ask...
I have an early HJ60 4spd. I have been told that the later 5spd will not bolt up??? Is this true?
I am well aware of the Driveshaft length issues and crossmember/g/box mount issues, that's not the problem. I was told the bell housing would not bolt up to the engine??
Anyone know the TRUTH?..

I'm about 99% positive that the bell-housings bolt up fine. According to this info splines should be OK too.

on back end of 2F bellhousings (1981-1984/5) the provisions for "ears" on the input shaft retainer of 5 speed do not exist. 10 minutes (long time guess) of grinding and the tranmission will fit.

(1985+ use the "3F" bellhousing, yes even in US).

I would assume same is true of 2H bellhousings.

to id the ears, look at the cast/machined figure 8 on the front end of the transmission. the top circle of the "8" has two bumps at 10 o clock and 2 o clock.

1985 and later transmissions are also clocked to right side 3-5 degrees but this should not be a problem.

that is correct. the bellhousing needs to be ground a bit, but it is more lke 3 minutes than 10 minutes

Can you explain this more. So if I went from the 2F bellhousing to the 3F the transmission on my 82 FJ60 would sit over to the right and not be centered on the hole in the floor anymore?

 

[rick_d]

clocked, mean rotated not moved to right side. tower of tranny still emerges out of same hole with plenty of clearance.

effect was to drop the t-case slightly therefore better aligning the output t-case flanges with pinions (engineering beyond my math skills).

I stuck a 5 speed in both a 1983 FJ60 with factory mount and 1981 FJ40 w/o issues, but both involved modifying the original 2F bellhousing.

fitting the 1HD-T w/ H55 (a clocked bellhousing like the 3F) in the 45 wagon project showed the 1981-1984 J40 mount I used had to be mounted higher on left side frame than on right. difference was about 3/4" as I remember.

....at most 10 minutes to do the job including 3 sips of beer, 1/2 a cigar, chucking in the tool and putting everything away.

These pics of a bellhousings from a 1HZ and a 2H both suit the h55f. cheers

 

[NocalFJ60]

I am trying to figure out why my new 5 speed is not lining up in the center of the hole in the floorboard. It is almost touching the hole on the passenger side. I have an 82 FJ60 and the bell housing was changed to the 3F. I have all the mounts in and snug.

Any ideas?

 

[rick_d]

then there appears to be a problem using a 3F bellhousing in place of the 2F.

if you have the 2F, switch back!

early and later tranny insulators have different forms, bevel base early flat base late.

there are a number of solutions to move the tranmission side to side with a late flat type, but none on the early. (HZ H55 rubber mounts are 1" to the side of 3B/2F)

Cheers guys,
so if i want to do tihs i use my existing bell housing and grind it to suit the 5 spd, correct?
So does this mean that i can't use the 5spd bell housing?
Thanks again.

 

[NocalFJ60]

I really am not in a position to switch back to the 2F bell housing now. I found out the cross member and rear engine mount is different for 82-84 & 84-87. I am wondering now if I just need a cross member from an 84-87 to make it fit better now.

Does anyone have a picture of the 84-87 cross member?

 

[Cruiserdrew]

It is true that the 81-84 crossmember is different from the 85-87. The rear motor mount is also different and not interchangable. However, if you have an 82, you can stick with the old mount as it bolts on to the same place on the tranny. The mounting spot does not change 4 speed vs 5 speed.

When I did mine, I reused the my cross member and replaced the rear mount with a later one--it didn't fit. I had to order a year specific one from CruiserDan. You must have the mount that goes with your cross member. I don't know your set up, but I don't believe you need a new cross member. Keep looking at the problem, you'll find it.

 

[rick_d]

later crossmembers bolt under the frame to welded braces on the inside and outside,

early have bolt on brackets only on the inside and the crossmember itself does not touch the frame. hard conversion DO NOT DO IT.

for clarification:
1974-1980 2F bellhousings use "legs" to suspend tranny- these could be removed and used for your (Kevin's) repair.

1981 to 11/84 (non us) OR to 4/85 (us) is what your trucks was delivered with.
(and 10/82 and later J40's and J60's with H55 used this bellhousing without fail)

later than that are 3F.

if the trucks is not on the road, and the radiator is out you can pull the engine, tranny, transfer in 2 hours, replace bellhousing on floor in 1/2 hour, and replace engine in 1/2 hour. (I know, I fought fitting H55-t-case in fj40 for 4 days then pulled and replaced engine -myself- in less time than those quoted above.

OK. so it's too hard. I kept getting told that i couldn't do it. So now i know the cross member doesn't bolt to the chassis.
Thanks!
