Description

Showtime Fabrication is pleased to offer this direct pin-on hydraulic thumb kit to fit your CAT 311/312/313/314 excavator.  We build our thumbs custom to fit your bucket teeth and coupler situation so please contact us to dial in your measurements and get a price if this exact thumb (as detailed below) won't work for you.
This specific thumb is 50" long from main pivot to tip of tines and 24" wide at the tips featuring four 1.0" thick AR400 steel tines.  It will arrive in a
flat black finish
.
If you have a quick coupler, direct pin-on bucket, or don't know what you have, please get in touch with us to get you the right thumb that fits perfect.  If you have a different model excavator, please see our other listings or contact us for a quote.  All of our thumbs are backed by a 1 year warranty so buy with confidence knowing you are getting a high quality attachment that will stand up to your abuse.
This is a complete thumb kit including everything but the hoses, so you'll just need to bring your auxiliary hydraulic lines to the cylinder ports.  This item will need to ship via truck freight/LTL which is usually 0-250 in the lower 48 to a commercial address with means to unload the pallet.  We can ship to residential addresses for a small additional fee.
Please contact us in advance with your zip code for a freight quote or international shipping.
This specific
thumb measures
24" wide and features four 1.0" thick AR400 steel tines which are CNC cut and specifically designed for grabbing rocks, brush, stumps, and more.  We do offer upgrades to 1.25" tines for this model as well for extreme duty applications.  We use our custom USA made 4" bore x 30" stroke 4000psi welded hydraulic cylinder with an induction hardened, chrome plated 2.5" rod, and oversized crosstube pins which will fit into the supplied cylinder mount to be welded on your machine.  The hydraulic cylinder also utilizes a hardline from the front port to the base so that the hoses connect out of harms way, and finally we install replaceable bushings in the cylinder crosstubes for easy future maintenance.  The cylinders are also fully rebuildable and utilize standard components.  All pins are included with this thumb kit including a longer 65mm main pin and they are turned from HT4142 USA steel to the appropriate spec.  The main pin is not supplied with a countersunk grease fitting, but can be for additional cost.
Protected grease fittings are provided at all pivoting locations so that all components of the thumb can be maintained.
As you can see, we offer a completely turn-key thumb package that is thousands of dollars less than the dealership while still offering incredible quality and components.  We have thousands of excavator thumbs in the field and we stand behind our product.  We have had great success with our thumbs and other attachments for many years.  For Customer Service, or if you have any additional questions on this or any of our products, please 'Ask Seller A Question' or j
