Hello all,

I was wondreing if anyone out there could help me with some information about replacing a Thomas power take off winch shear pin?

I just recently bought the above mentioned vehicle and in my excitement filled haste, forgot to release the handbrake while experimenting with the winch. Ahh the things we do! Lucky it was in the comfort of my driveway and not some boghole in the middle of, well anywhere because I have yet to find a replacement pin.

I looked it up in my original Toyota manual but the winch described in that is of a different design. My winch must be after market.

Any info would be greatly appreciated.

Yes it is after market. The shear pin is located just behind the gear box, you will need a pin punch to nock the old one out (leave it in the glove box, punch that is) as for replacements I found a cotter pin was the best to use, available at most nut and bolt places.

Match up the size with the old one, and get a couple of spares.

Jim, the shear pin is of a particular shear-off value that will shear off before any overload occurs to the winch and drive line. These are available from Landcruiser Field services in Moe, Victoria, about a dollar each. Two sizes are available depending on the model year. I find that it is easier to loosen off a saddle bearing mount to access the pin which is located through the body of the first cardan joint near the winch end. The copper-coated pin is knocked through with a pin punch. Aligning the holes for the new pin is the tricky part. Later pins have tiny spit pins at each end to allow easier fitment. Breaking the pin is a warning that all is not right with your tackle set up. You need to consider another snatch block or two, to lessen the load and increase the mechanicl advantage in your favour. In the army, two pins and you were out!

I thank you all for your responses and I have a question for desert.

Can you please describe for me what a cardan joint is?

Is it that chain wrapped disc mounted on the winch drive shaft just behind the winch itself?

Jim, disregard the comment I made re cardan joint. As you stated you had the "chain wrapped" coupling, that is where the shear pin is located; on the vehicle side of that "chain coupling". I just had a scratch about in the shed and found one with the pin still inserted. But, as I said, you may need to disconnect another bearing saddle back along the drive shafts, so that the shafts will droop more. This will allow you to slide the shaft out of the chain coupling, which will reveal the broken shear pin pieces. Tap them out, install the new pin and remount the bearing saddle and you are done.In future you can "witness mark" the coupling and the shaft so that you know when the holes are aligned to allow you to drive the broken pin through, without having to go to the bother of all of the above.

Hi Jim, the distributor on Melb for these parts is powauto I think it is the sam ein Adelaide. DO NOT replace this part with a cotter pin, I had a rusted up pin and ended up stretching hte chassis 2 inches and busted the main winch shaft. cost 200 buck Oh well, keep the shear pins greased now!!!!
