does any one know some tricks to getting this cover back on a late model D2?
I removed the cover,the shaft and the yoke as a unit as the service book says,but cant get it back together either complete or separate.
the left brake pedal in particular is really being a PITA and I am tempted to cut it off with the gas axe LOL.
any suggestions appreciated

Hi Team,
can you undo the bolts holding on the brake pedal mount housing and then lay the pedal/mount back towards the rear of the machine to gain clearance.

My OMI addition for the Oil Clutch Service Information, it shows the clutch operators lever removed from its shaft.

In part of the text under NOTE is a piece of what looks to be heavy gauge wire linked from said shaft into the clutch cover opening is holding up and in a certain position the throw out fork lever--forward of centre --it says to facilitate cover removal and replacement.
I feel you may need to run another piece from to fork out and over to the vertical control shaft to hold the fork in a neutral position as I can see one wire pulling it rearwards due to the weight of the rod, fork etc.

Picture is dark and may not copy well.

Have not time to copy said instruction now and will see how I go tomorrow--
Cheers,
Eddie B.

Hi Team,
here are scans from a Cat Release with the introduction of the Oil Clutch, Form No 30942, Dated 11-53 for Tractors S/No's
4U 6373-up and 5U 13237-up.
Missing are the front and rear pages that do not have data for servicing on them.

Hope these help--save them now if you have a D2 as such.

Cheers,
Eddie B.

Thankyou Eddie for the replies and literature.
I have found that Putting the cover back on by yourself is a real battle and so still haven't got it on yet.
I hope to get some time and help latter this week.

Hi Team,
maybe, if you have not already, remove the vertical shaft and try that way.

I had a cover off one time on a clients machine to re-do the starter pinion assembly from the rear--as is known to occur the pinion gear had fallen off after the 4 bolts came out.
Do not recall much trouble but I had the workshop crane to do the grunt work and luckily it was a later unit with the same clutch cover as yours.
Good luck.
Cheers,
Eddie B.

with some help from a neighbour I managed to get it all back together. Was wondering is there a genuine washer that goes at 5 in this picture? my parts book doesn't list it, however shows it several times.
IMO It must help set the vertical clearance on the fork and thrust BRG collar.

Hi Team,
I do not have a Parts Book for a later D2 with your clutch cover, BUT, in my post #3, the last scan shows both a washer (😎 and a seal (7) on the shaft below the outer lever so I assume they should be shown in a Parts Book.

I have included a Service Mag. article from which covers mods before your S/No and cover, but may have relevant P/No's for you for the washers--(S94) = 0S 0094.
Cheers,
Eddie B.

Thanks Eddie
After looking at the machine today that service mag article makes good sense Regarding the two S94 washers.The parts book shows the S94 washer x 1 only which didn't make sense to me.
That S94 washer is just a plain washer nothing special, so I will machine one up to suit.
Also the clutch seems to have a slight rattle to it while engaged or disengaged. I think it is the back lash between the teeth on the plate and flywheel. I don't recall it being there before but think it has developed since I have cleaned the crud off the teeth while it was dismantled. I hope to get down to Mike's one day to return a Carby body of his, and at the same time maybe check out his d2 clutch.
That way at least I'll know what's normal and what's not.

Hi Team,
check your low idle speed --the Rack Chart says 500RPM. I have sometimes found that each engine is individual in that the sweet running spot(RPM) can be +or- a few revs (20-30 up) of that Spec RPM.
Try adjusting up with the hand lever or if no change you will need to adjust the LI stop down a bit to see if the rattle comes out--a slightly misfiring injector or any other mechanical issue causing one cyl to be low in compression can cause a 4 cylinder engine to Idle rough.

Just as an example on early 428 Back Hoe Loaders with Perkins 4 cyl. engines we had to get them up to around 1050 RPM Low Idle (from around 800 from memory) so they did not shake the machine to pieces--they idle against a fair load from the trans and hydraulics so need the speed for smoothness-- yes, it does seem a bit high but did not cause any issues and solved a lot of complaints of cracked mufflers and cabin parts rattling etc.--smarter operators simply set the hand throttles up a touch to find the smooth/sweet spot and worked from there.

Clutch Actuator Shaft,
Yep, later on I did find the dimensions of the 0S0094 washer in my early Thirty Parts Book as they are Best style Part Numbers.
0S0094 spacer washer 1 11/16" OD, X 1 1/64" ID, X No 12 Gauge Steel (0.1094" US Gauge or approx. 2.78mm)
