Carrier gearbox Q+A’s

[Lynn Eades]

Richie the shaft is a bigger dia. at the end to tighten it up as it arrives home. I'm wondering. Does your gbox have thrust washers at each end of the cluster, or just one? (or none?) If it has two, try assembling it without the front one? See what happens now? Try tapping the shaft back, so that it is against the location plate. In 1963 the Eng. Ford industrial engines (equiped with manual 4 speed) had two thrusts, both the same part number. Does that help at all?

Cheers Lynn I will have a look, I noticed on the exploded diagram there are cross cut bronze thrust shims, yet on mine there are none (and no space to fit them)

The Dodge 4 speed crash box has no thrusts, but some Ford boxes do. They share the Cluster, reverse idler, The gears on the main shaft and sometimes the main shaft (not with the carrier though) the input (spigot shaft) is not shared. The selector forks and shafts are common as well. I'm not familiar with the genealogy, but I know the Dodge was New Process, I guess Ford did their own thing, and I believe Clarke used / made these gear boxes in manual forklifts of the era. Maybe the Ford counter shaft (cluster) pin needs relieving at the end or grinding at the locating slot to let it sit that little bit further back? There cant be much in it. Is you pin a replacement?

[RichardT10829]

No the pin is original as is the cluster. I put the worn original needle bearings back in with the same issue. I will do some more investigating.

[Lynn Eades]

Now you're making it difficult.

Located my DTI gauge and put the shaft in the chuck of my lathe… it’s bent

Looks like I need to find another cluster gear shaft.

O'neill Vintage Ford list 5 of them @ 22.95 incl. VAT under part number B-7111
The carrier part number in the 1941 parts book is 51-7111. It might pay to check it is the correct one.
I find it hard to imagine how it would get bent?
