spur gears and mesh

[BTA2997]

I Broke My Spur Gear Jumping My Truck Today And I Was Looking At The Metal Spur, I Have Heard Good And Bad Things About Running A Metal Spur, Like If You Run Metal You Run A Larger Risk Of Tearing Up Tranny Gears, So I Am Undecided On Metal Or Plastic. Also How About The Gear Mesh, I Just Sold An Old Truck And How I Did That Truck Was Get Them Close As Possible. If Anybody Has Any Input Or Knows A Good Way To Mesh The Gears Or What's Better Metal Or Plastic Let Me Know

If I were you I would stay with the plastic spur just for the reason you mentioned above, a $5 or $6 dollar spur is cheap and easy compared to opening up the trans. When you change out the spur gear, put a small strip of notebook paper between the gears and push them up tight. When you remove the paper the mess should be just right. After you set up a few this way you will get the feel for how it should be in the future.

Good Luck

Thanks, I Have Seen People Who Run Metal Spur And Stock Tranny Gears I Just Kinda Agree I Would Rather Replace The Spur Than The Tranny Gears, Oh One More Question Have Any Of You Ever Heard Of Anyone Using Lock Washers On The Engine Mounts?

[daparrothead]

Blue loctite is your best bet, you can use lock washer's also if there is clearance just make sure the screw is long enough to get full thread engaugement.

i think i would go with the plastic one like all the other people said, the plastic spur gear is cheaper to replace that the tranny gears

I would stick to the plastic as well. I run plastic on my bigblock t-maxx with an axial.28. I can get like a gallon out of a spur gear. When meshed correctly they will last a long time. I have even stripped tranny gears running a plastic spur. If you are going to be doing alot of jumping I would not be afraid of loosining the slipper about 1/8th turn of so. This is relative to the engine you are running. Be sure you are not on the on the throttle when landing if possible. Just my 2 cents.
